It has been cultivated and consumed for centuries, and today it is one of the most valuable agricultural commodities in the world. On average, Canadian coffee fans consume 2.6 cups of the stuff per day, according to 2003 figures from the Coffee Association of Canada.
We know that Wine Access readers put a lot of thought into what goes in their wine glass. But do you put the same level of attention into the contents of your coffee mug?
“I’ve been working in coffee for about 8 years and I do notice that people want to know more about it, but there’s still a lot of people that just — they don’t have any idea the many aspects that there are to coffee,” says Amanda Wiley, regional operations manager of Waves Coffee House in Alberta.
We talked to Wiley and Peter Izzo, another Calgary-based coffee expert, to give you the basics of what you need to know about joe.
Where Does Coffee Come From?
There are three major coffee-growing areas in the world: Latin America, Africa and the southeastern parts of Asia, particularly Indonesia. Like wine, the soil in which the coffee is grown can affect the flavour profile, but altitude is also a major factor, according to Izzo, owner of Cappuccino King, a retail store selling and servicing high-end coffee equipment. The best beans, he says, are grown between 3,000 and 4,500 feet above sea level.
These beans are most likely to be Arabica, one of the two main species of coffee produced for human consumption. Arabicas are the higher quality beans — they take longer to mature and are bigger and more flavourful than Robusta beans, which can be bitter, but have a better crema (the thin layer of reddish foam on top of an espresso) when brewed.
Within these two species, there are many different varietals, frequently named after where the beans are grown (think Java, Kona and Jamaican Blue Mountain), but sometimes there is such a small lot of a varietal that it is designated only by number, Izzo says.
Unlike wine, most of the coffee you’ll find will be a blend. Blended coffees use different varietals, different roasts and even small amounts of Robusta beans to create a specific flavour and mouthfeel.
One trend that’s becoming more popular is single-origin coffee — one varietal from a specific lot, roasted in a particular way. But, Izzo says, it will likely always remain a boutique product.
And don’t even try looking for a single-origin espresso, says Wiley.
“Espresso is so dynamic and has so many different layers to it, and in order to create what you want to create, from the flavour to just consistency and how you get that nice rich crema on top, so often it will be a blend of three or more coffees,” she says.
How to Buy Coffee
The first step in preparing a good cup of coffee is finding a coffee that you like. A lot of this is trial and error — simply figuring out what you like or dislike about the coffee you presently drink and trying different products in line with what you like.
In a grocery store aisle, Wiley says, bags of coffee will frequently have descriptions on the back labels (like you see on bottles of wine). Alternatively, you can visit a specialty store or coffee shop, where the staff should be able to tell you more about the products.
Some general pointers to keep in mind are that Latin American coffees usually have nutty flavours, African coffees have floral or citrus notes and Asia-Pacific coffees have earthy flavours. Latin American coffees tend to have higher acidity and African coffees are less acidic.
If you stay away from dark roast because you don’t like strong or bitter coffee, Wiley advises that what people perceive as strength or bitterness is frequently acidity. Lighter roasts are actually more acidic than dark, which tend to have more sweet or roasted flavours, more body and less “acidic punch,” she says. Wiley suggests experimenting with dark roasts, but avoiding those that have “smoky” as a prominent descriptor, as those tend to be the darkest roasted.
Before you can brew your new coffee, it will need to be ground. It is important to tailor the grind to the type of machine you’ll be using, Wiley says, and most home grinders (the ones with the blade) aren’t up to the job. For this reason, she suggests having coffee ground at the point of purchase, in a proper burr grinder. Once it’s ground, though, use it quickly — within 7 to 10 days, Wiley says.
How to Prepare Coffee
To taste test your new coffee, Wiley recommends using a French press, her favourite method of preparing coffee. It’s the brewing process that’s closest to cupping, which is how roasters taste their coffees, as it allows more contact between the water and the coffee grinds. It produces a drink with a slight grittiness, more flavour and higher caffeine levels, Wiley says.
“It does the coffee more justice,” she says.
If you’re using a machine, Izzo advises that there are a few things you can do to ensure your coffee continues to taste as it should
-
Check that your equipment is clean.
-
Use good water — some municipal tap water has odd flavours and aromas that will affect the taste of the coffee.
-
Make sure you use the proper coffee-to-water ratio for your coffee. More coffee does not equal a stronger cup!
-
If you have a machine where you can control the brewing temperature, check that it’s about 200°F (give or take about 5°F depending on altitude). Hotter water will burn the coffee and colder water won’t extract all the flavours.
Finally, it’s important to note that even your favourite coffee won’t taste great if it’s stale. Make sure you’re buying coffee that’s fresh — roasted coffee beans are good for up to 6 months past the roasting date, but are best between 5 and 6 weeks. Coffee should be stored in an airtight container in a cool, dark place (but not in the freezer). Once the bag is open, it only has about a week before it starts to lose flavour, so drink up!
