Tim Hortons supersizes its coffee cups

Tim Hortons new sizes. The beloved Canadian coffee joint will shift the names of its sizes starting Monday to make room for a 24 oz. cup — the new extra large. Small will become extra small, medium will become small and so forth, making the sizes more comparable to American standards
Size matters

Tim Hortons new sizes:
Extra small – 8 oz.
Small – 10 oz.
Medium – 14 oz.
Large – 20 oz.
Extra large – 24 oz.

Starbucks:
Short – 8 oz.
Tall – 12 oz.
Grande – 16 oz.
Venti – 20 oz.
Trenta – 31 oz.

You know that large Tim Hortons double double you order every morning — well it’s now a medium.
Timmies is now giving you more coffee but not increasing the cost.The beloved Canadian coffee joint will shift the names of its sizes starting Monday to make room for a 24 oz. cup – the new extra large.

Small will become extra small, medium will become small and so forth, making the sizes more comparable to American standards.

“We tested the names of the new hot cup sizes with our guests and the response has been overwhelmingly positive,” said Dave McKay, a marketing director at Tim Hortons, in a statement.

At 8 oz., the current small is not available in the U.S., but will remain at the approximately 3,225 Tim Hortons locations in Canada.

Customers will pay the same price for the same amount of coffee, according to the statement.

Ordering a large coffee will put an extra 6 ounces of coffee in your system, making the new large the same size as a 20 oz. Starbucks venti. Starbucks tall (small) and grande (medium) sizes will be 2 oz. larger than the same sizes at Tim Hortons.

To cater to its consumers’ expanding desires – and waistlines – the American premium coffee giant introduced a 31 oz. cup called the Trenta in January 2011.

Health Canada recommends that adults have no more than 400 mg of caffeine per day – about the amount in a 24 oz. of coffee, it says. (There is 200 mg of caffeine in Tim Hortons’ current 20 oz cup, according to its website.)

Green Mountain, Starbucks get jolt from coffee deal

SIMON AVERY — INVESTMENT REPORTER
From Friday’s Globe and Mail
Published Thursday, Mar. 10, 2011 7:26PM EST

Last updated Wednesday, Apr. 13, 2011 7:36PM EDA deal between rivals Green Mountain Coffee Roasters Inc. (GMCR-Q50.90-1.27-2.43%) and Starbucks Corp. (SBUX-Q48.150.130.27%) to sell single-serve coffee sent shares of both companies soaring Thursday, raising the question whether there is a bubble brewing in the caffeine business.

Green Mountain, which dominates the single-cup home-brewing market, agreed to sell Starbucks coffee and Tazo tea for its Keurig system. For Green Mountain, the arrangement is expected to boost revenue for both its brewing systems and its coffee and hold off further competition in the $2-billion (U.S.)-a-year market. Starbucks, in turn, is spared having to develop its own single-cup brewing device, potentially saving the company hundreds of millions of dollars.

How to make the best coffee of your life

CHRIS NUTTALL-SMITH
From Wednesday’s Globe and Mail Published Tuesday, Jan. 10, 2012 5:50PM EST
Last updated Wednesday, Jan. 11, 2012 5:08PM EST

In the couple of decades since North America first started caring about its coffee, espresso has reigned as the king of the brews. If you wanted to make truly great home coffee, you had little choice but to spend upward of $1,000 on a brass-boilered espresso maker and specialty grinder.

But in the last 18 months or so, espresso has lost much of its lustre to cheaper, easier brewing methods that many in the coffee world say can make just as good a drink. High-end coffee shops and java geeks who once lived and died by pressure-brewed beans have rediscovered old-fashioned vacuum siphon pots, French presses, drip brewing (yes, drip!) and even a $30 specialty press-pot of sorts that was invented by the maker of the Aerobie, that Frisbee-like flying orange disc. Used properly, enthusiasts say, these brewers allow home-bound coffee hounds to do the near-impossible: to capture the complex smells and flavours of fresh-roasted coffee beans in liquid form in cup after consistently brilliant cup.

And so, for one progressively caffeine-jacked week, I holed up in my kitchen with a gram scale, a stopwatch, a thermometer, a “precision pour” water kettle, a hand-cranked ceramic burr grinder from Japan, plus five different coffee apparatuses and nearly $100 worth of freshly roasted, single-origin, micro-batch coffee beans that variously promised tastes of praline, orange, caramel, toasted nuts, tropical fruit, earth, cherry pie, citrus fruit, tarragon and crème brûlée.

I admit that I never did taste tarragon. But I did manage to make several of the best coffees of my life.

The Good The first glass vacuum pot was patented in the late 1830s and the method hasn’t changed much since. Consisting of a large, lower glass bulb that you fill with water, an upper glass bulb that fits snugly on top of it and a glass siphon that connects the two, it’s an excellent party trick. As the water in the lower chamber boils, vapour pressure pushes it up the siphon into the upper compartment, where it mixes with coffee grounds. You stir, then let it steep for a minute, then remove the pot from the heat and the coffee gurgles and floods its way through a filter back into the lower bulb.

The vacuum pot I used, which is made by Bodum, was easily the most entertaining of the brewing methods I tried. Yet there are plenty of downsides: The siphon tubes, made from thin glass, are infinitely breakable, and between the careful heating, the requisite stirring and the precariousness of moving a pair of stacked glass orbs from the burner, the process is about as far as you can get from dump and brew.

After some fiddling, I managed to make a pot of crystal-clear brew that balanced nicely between earthy, caramel low tones and fruity highs. Which is to say that it was better than most of the non-espresso coffee I’d ever had. But getting there took a whole lot of bother. I moved on before too long.

The Not Bad

Since it appeared in Modernist Cuisine last year, there’s been a renewed interest in the Toddy, a cold-brewing system first introduced in the 1960s. The chief benefit of the method is its lack of acidity. (Toddy coffee has 67 per cent less acid than regular drip, the company says.) It’s simple, too: You dump most of a pound of ground coffee and two litres of cold water into a steeping chamber and then refrigerate it for between 12 and 18 hours. You then pull a cork from the bottom of the chamber and let it slowly filter into a jar, which you can store for two weeks. Whenever you want a cup, you mix the concentrate with boiling water, or cold water if you want to serve it iced. (You can even use cream or alcohol in place of the water, Modernist Cuisine’s authors enthused.)

But the lack of acidity is also its weakness: If the goal of brewing coffee is to extract the smells and flavours and complexity of the beans, cold brewing only succeeds half-way. The stuff I made tasted like a liquid Tootsie Roll, with none of the brightness or balance that makes for something great.

Out of a sense of duty to French-press fanatics, I made French-press coffee on a new, semi-automatic Bodum French-press machine that heats the water and then mixes it in the press pot with the grounds. I don’t get French-press coffee. No matter how many ways I made it, it tasted like good coffee mixed with coffee sludge.

The Amazing

I had little faith that anything good would come of the AeroPress, a tubular contraption invented in 2005 by the creator of the Aerobie flying ring. The press, which costs around $35 and is made from rubber and (BPA-free) plastic, works a little like an open-bottomed French press: You pour in grounds, add hot water, quickly stir and then press a plunger to push the resulting coffee through a paper or micro-perforated steel filter into a sturdy mug. The system has built a bordering-on-rabid following in the last few years; there’s now an annual World AeroPress Championship and high-level coffee dorks are known to pack them when they leave home for more than a couple of hours.

My first attempts weren’t particularly successful. If you follow the instructions on the AeroPress packaging, the water starts trickling through the grounds and into your cup before you even press the plunger. But that’s what YouTube is for: The site is loaded with videos of AeroPress advocates making coffee. They almost universally operate them upside down, and then carefully flip them over while holding the mug underneath. It’s easy to tip the whole thing over, of course (the AeroPress was clearly not designed to be used upside down) and spill half-brewed coffee everywhere. Which I did. Twice. But after a few tries, the coffee I made was fantastic: rich, delicious, notably sweet-tasting and smartly balanced. I plan to keep one, along with a little hand-cranked grinder, at my desk from now on. I may never drink stale cafeteria coffee again.

The Best

In the summer of 2010, Hario Glass Company, a Japanese consumer-products firm, introduced the V60 manual pour-over drip filter cone to North America. The product almost instantly transformed drip brewing in the minds of coffee’s early-adopting elite. The V60 is not like other manual drip cones: Its ceramic surface is covered with a vortex of raised vertical ridges that allow coffee to escape out a paper filter’s sides as well as its bottom. The cone’s bottom has a hole as wide as a nickel where the filtered coffee can pass into a cup. Hario’s paper filters culminate in a pointed cone, so the water has to pass through a thick bed of grounds before it hits the cup. But the best thing about the V60 is that it allows complete control over the brewing process, particularly when used with a stopwatch, set on a scale and slowly filled with hot water via a precision-pouring kettle.

There’s no end of technique required. You need to pre-wet the filter and cone with a litre of near-boiling water to remove any paper filter taste and then measure out between 12 and 18 grams of fresh grounds for a small single cup. Your water should be just below 200 degrees Fahrenheit, and after you’ve set a mug and the filter cone and the pre-washed filter and the grounds on a gram scale, you need to pour in about 40 grams of 200-degree water and then leave it for 30 seconds to let the CO2 in your freshly roasted grounds bloom.

After that, you pour slowly in concentric, counterclockwise circles from the inside out, never touching the paper filter with the stream of water, and all the while watching your stopwatch as it ticks toward three or four minutes, which is the ideal brewing time. You need to watch the scale, too: It takes about 260 grams of water to make a small cup. All of this, admittedly, is one of the most precious-sounding things I’ve done in life so far. But, damn the coffee tastes spectacular.

Done properly, drip coffee is rich, satisfying and full of body. It tastes exactly the way great, freshly roasted, fresh-ground beans smell. Depending what beans I was using, it tasted of praline, orange, caramel, toasted nuts, tropical fruit, earth, cherry pie, red wine, citrus fruit and even chocolate-covered blueberry compote, though I didn’t find that anywhere in the descriptions on the coffee bags.

Honestly, it did. I swear.

How Coffee Can Galvanize Your Workout

December 14, 2011, 12:01 AM nytimes 

By GRETCHEN REYNOLDS

Phys Ed

Can a cup of coffee motivate you to relish your trips to the gym this winter? That question is at the heart of a notable study of caffeine and exercise, one of several new experiments suggesting that, whatever your sport, caffeine may allow you to perform better and enjoy yourself more.

Scientists and many athletes have known for years, of course, that a cup of coffee before a workout jolts athletic performance, especially in endurance sports like distance running and cycling. Caffeine has been proven to increase the number of fatty acids circulating in the bloodstream, which enables people to run or pedal longer (since their muscles can absorb and burn that fat for fuel and save the body’s limited stores of carbohydrates until later in the workout). As a result, caffeine, which is legal under International Olympic Committee rules, is the most popular drug in sports. More than two-thirds of about 20,680 Olympic athletes studied for a recent report had caffeine in their urine, with use highest among triathletes, cyclists and rowers.

But whether and how caffeine affects other, less-aerobic activities, like weight training or playing a stop-and-go team sport like soccer or basketball, has been less clear.

So researchers at Coventry University in England recently recruited 13 fit young men and asked them to repeat a standard weight-training gym regimen on several occasions. An hour before one workout, the men consumed a sugar-free energy drink containing caffeine. An hour before another, they drank the same beverage, minus the caffeine. Then the men lifted, pressed and squatted, performing each exercise until they were exhausted.

Exhaustion arrived much later for those who’d had caffeine first. After swallowing the caffeinated beverage, the men completed significantly more repetitions of the exercises than after the placebo. They also reported feeling subjectively less tired during the entire bout and, in perhaps the most interesting finding, said that they were eager to repeat the whole workout again soon.

“Essentially, we found that with the caffeinated drink, the person felt more able to invest effort,” says Michael Duncan, a senior lecturer in sports science at the University of Exeter in England and lead author of the study. “They would put more work into the training session, and when the session was finished, in the presence of the caffeinated drink, they were more psychologically ready to go again.”

How caffeine influences the physiology and psychology of weight trainers isn’t fully understood, Dr. Duncan says. In contrast to endurance sports, an increase in fats in the blood wouldn’t provide much benefit in this kind of exercise.

Instead, Dr. Duncan says, he believes that caffeine “antagonizes adenosine,” a substance in muscles that builds up during exercise and blunts the force of contractions. The more adenosine in a muscle, the less force it generates. Caffeine reduces adenosine levels, “which then enables more forceful muscular contractions and delays fatigue,” Dr. Duncan says. “That’s the theory, anyway,” he adds.

Additional mechanisms may also be at work, other research suggests. For an experiment published last month in The Journal of Applied Physiology, researchers asked a group of volunteers who regularly play team sports to complete a grueling workout designed to simulate the physical exertion of a soccer or basketball game. Such sports commonly involve repeated bouts of intense sprinting, but little prolonged slower running. Most of the effort is anaerobic.

In the test, the volunteers performed about 16 percent better if they had ingested a caffeine capsule 70 minutes beforehand. They also, as it turned out, had far less potassium in the fluid between their muscles afterward. “We believe that potassium buildup is involved” in the kind of fatigue that occurs during anaerobic activities, like team sports and weight training, says one of the study’s authors, Magni Mohr, an exercise physiologist affiliated with both the University of Exeter and the University of Copenhagen in Denmark.

At the same time, caffeine, while affecting muscles, seems also to have a striking effect on the central nervous system and on those parts of the brain involved in mood, alertness and fine motor coordination during exercise. In a study published last month in The British Journal of Sports Medicine, soccer players dribbled, headed and kicked the ball more accurately if they’d had caffeine than if they hadn’t.

All of which would seem to indicate that a grande Americano is the ideal sports beverage. But, Dr. Mohr cautions, many questions remain. “We don’t know the best dose” of caffeine to provide performance benefits without undesirable side effects, he says, like heightened blood pressure or the jitters. In his study, volunteers consumed the equivalent of more than five large cups of brewed coffee before their workout.

Similarly, it’s not known whether people who swill cappuccinos and green tea all day get the same benefits from dosing themselves just before a workout as people who only occasionally drink caffeine, or whether the hour before a workout is the ideal moment to imbibe. Dr. Mohr suspects “it’s likely that you get more effect” if you’re not habituated to the drug, but he and others are currently studying those and similar issues and expect results soon.

In the meantime, “probably everyone can get some” fatigue-delaying and mood-enhancing benefits from caffeine, Dr. Mohr says — meaning that your gym gear should probably include a travel mug.

Caffeine levels depend on preparation

(From BCuz.com)
Depending on the type of coffee and method of preparation, the caffeine content of a single serving can vary greatly. On average, a single cup of coffee of about 207 milliliters (7 fluid ounces) or a single shot of espresso of about 30 mL (1oz) can be expected to contain the following amounts of caffeine:[81][82][83]

Java jargon: Coffee lovers take language lessons from wine snobs

Vocabulary of wine is being adopted by connoisseurs of coffee, chocolate and other foods By Colleen Ross, CBC News Posted: Sep 15, 2011 8:01 AM

About The Author  Colleen Ross is a national news producer for CBC Radio in Toronto with master’s degrees in English literature and journalism. Trilingual, she has lived on three continents and taught at a German university before entering journalism. She is originally from Fruitvale, B.C. (Note:CBC does not endorse and is not responsible for the content of external links.)

You’ve been there, sitting in a restaurant beside some tweed jacket type who swills his glass of red through tobacco-stained teeth and expounds on the delicate notes of currants and figs, the slight eucalyptus aftertaste. Or perhaps the young professional, giant sunglasses perched on immaculate updo, droning about the complexity of the white, what with its blend of vanilla and lemon, its slight taste of cotton sheets.

Really? Who tastes their sheets?

Let’s face it, wine snobs are annoying — what with the way they crowbar ordinary words to describe something many of us just slug back and quietly enjoy.

Well, now there’s a new snob on the block. With the growing interest in purity, body and single-origin, this drinking dialect is expanding to a different beverage.

Coffee, it seems, is the new wine.

It was inevitable. Most accounts plant the origin of the word “coffee” in the 1600s. It stems from the Turkish word kahveh and the Arabic wordqahwah, which originally meant –– wait for it –– wine.

History professor Ralph S. Hattox explains the etymology in his bookCoffee and Coffeehouses: The Origins of a Social Beverage in the Medieval Near East:

“The Arabic root q-h-w/y denotes the idea of making something repugnant, or lessening one’s desire for something,” he writes.

“According to one medieval Arab lexicographer, qahwa is ‘wine, so named because it puts the drinker off his food; that is to say, it removes his appetite [for it].’ The application of this term to coffee was a simple step: just as wine removes one’s desire for food, so coffee removes one’s desire for sleep.”

‘Pure coffee’

So, with coffee linguistically linked to wine, it makes sense that we’re now using similar language to describe it.

With a disdain for foam, the caffeinated wine snob is embracing “pure coffee,” mimicking the move from table wine to Cabernet, if you will. A quick trip to a few pure-coffee blogs yields the following: “the coffee held notes of fig, chocolate milk, a bit of wheat, black bean and bran. The overall feel was smooth with a little kick. As it cooled, a smokiness entered the sensory picture.”

And, “the espresso held bright lemon, ginger, rosemary, milk chocolate, with a velvety texture amidst a brown healthy crema.”

That all sounds quite nice, but I’ve never detected rosemary in my espresso. Then again, the two packets of sugar eliminate the need for all but one adjective: “sweet.”

Coffee connoisseurs talk more about single-origin or single-estate coffee, made with beans from one country or one farm. So, instead of Bordeaux and Gray Monk Riesling, you have Costa Rican Tarrazu and Panama Geisha Aristar.

And what of body? Like wine, java has body, and it’s being increasingly sized up (better assessed if you swirl it in your mouth). We yak about Brazilian and Honduran coffee having light and medium body, of Tanzanian beans being full-bodied.

So, why is java jargon becoming more refined?

Chocolate, salt also have own vocabulary

Morton Satin says people are trying to express their individuality through the products they consume. He’s the author of Coffee Talk: The Stimulating Story of the World’s Most Popular Brew and vice-president of the Salt Institute, a trade association for salt producers. Satin says it starts with marketers making us want to buy a product like coffee or wine and is driven by the likes of the Food Channel.

Once we taste a product and learn more about its nuances, we then need the language to describe it.

Satin says what’s happened with oenological language is spreading to not only coffee but chocolate, too. The brown stuff is described in terms of how well-tempered it is (whether it has a good gloss and healthy snap); its aroma (released by rubbing the chocolate with your thumb), which can range from kumquat and mushroom to juniper and baked bread; and how it melts in your mouth: creamy or greasy, or perhaps waxy and gritty. Like wine and coffee, more attention is paid to terroir, and cacao content is also of essence.

Satin says even salt is getting more descriptors. We used to speak merely of table salt, but there’s also kosher salt, sea salt and fleur de sel(an expensive sea salt harvested from the surface of pools of evaporating sea water in France that is said to have high mineral content). There’s Brittany and Japanese sea salt, Hawaiian sea salt, Himalayan rock salt, finishing salt, flake salt,Kala Namak and now even smoked sea salt.

Satin likes the idea of using more refined language to describe the essential things we consume. It means we’re trying to renew our interest in the basics of life, he says, that “we’re starting to recoup a certain part of our consciousness, so our life isn’t just about work.”

This new language doesn’t initially roll off the tongue, Satin admits, so we have to practise it, but as we gain more confidence in knowing what is a good wine and what is good coffee, chocolate and salt, we’ll eventually have the words for it.

And we may already have the words, even if they’re not snob-sanctioned. At a wine-tasting party I attended a while back, we had to come up with a few lines for each wine.

People wrote descriptions like “cinnamon velvet” and “amber mist.” But my favourite was an Australian Shiraz someone said tasted like a “sunset in Manitoba.” I can’t think of finer language

Coffee Bean Mosaic Makes Guinness World Record

International Business Times by Cristina Merrill | Dec 13, 2011 07:19 PM EDT

An Albanian artist has landed himself in the Guinness World Records again thanks to a mosaic he made out of one million coffee beans.

Artist Saimir Strati used 309 pounds of coffee beans to create a mosaic — now recognized as the largest coffee bean mosaic in the world — that features five people from around the globe: an African drummer, a Brazilian dancer, a European accordion player, a Japanese drummer, and a U.S. country singer, Reuters reported.

“I wanted to give the message that sharing love over a cup of coffee brings us closer, a cup of coffee brings us more love than a G20 meeting,” he told Reuters.

This marks Strati’s sixth time in the Guinness World Records. A previous entry was made entirely of 229,764 corks and depicted the Mediterranean region.

“I also wanted to appeal to Mediterranean countries not to create mosaics based on computer pixels, but as our forefathers did,” he said of that work of art in 2008. “The Mediterranean is the home of the mosaic.”
