Canadians
drink over 15 billion cups of coffee every year. Whether
relaxing and gathering with friends or starting your
day with the aroma and taste of fresh coffee, this ancient
and exciting drink is Canada's favourite hot beverage.
Creating coffee's varying taste characteristics is a
fine art, utilizing different countries of origin, roast
styles and blending profiles. Appreciating coffee's
differing taste profiles is only one part of the coffee
beverage experience.
How
you store and prepare coffee at home will have a dramatic
impact on the freshness and "quality" of your
cup.
The
information presented here will improve your knowledge
on brewing and storing roasted coffee. Using the guidelines
that follow will ensure that your coffee's full body
and unique characteristics can be fully appreciated.
This
information is based on the Coffee Association of Canada's
"Guidelines for Storing and Preparing Brewed Coffee",
developed in June 1996.
The
following offers a step-by-step guide to preparing your
favourite cup of coffee.
Amount
of Coffee - The amount of coffee that you use will
affect the strength of the finished cup, and should
be based on personal taste preference. Industry experts
agree that 1 to 1.5 tablespoons (15-25mL) of coffee,
per 6 ounce (175mL) cup, will ensure full development
of coffee characteristics. Many roasters and retailers
provide recommended serving sizes to be utilized for
further guidance.
Coffee
Grind - The grind style you choose will also affect
the strength of your coffee. Too fine a grind will result
in a strong, perhaps bitter, cup, and too coarse a grind
will result in a weak cup. The grind must also match
the design of your coffee machine.
Establishing
a consistent grind is a key element of coffee quality.
When considering grinders for home, be aware that machines
that "grind" with discs will offer a more
consistent result than those that "chop" with
blades.
Water
- A cup of coffee is 98% water. To paraphrase a saying,
the quality of the water that goes in, determines the
quality of the coffee that comes out. Always use freshly
drawn cold water, ideally filtered through an activated
carbon filter. Avoid artificially softened water which
will result in a "flat" tasting cup.
Coffee
Machines
- The answer to one of the most commonly asked questions
... "why does the cup of coffee I buy in my favourite
restaurant or coffee shop taste different than the coffee
I make at home?" ... is usually equipment related.
The performance of coffee machines varies depending
on the temperature of the water and the speed at which
the water passes over the coffee grinds. Restaurant
and coffee shop machines are specifically designed to
achieve water temperatures of 200oF (75oC) and "draw
times" of between 3½ to 4½ minutes
per pot. It is difficult for in-home brewers to achieve
the same standards, but these parameters can be used
as a benchmark for your machine.
To
avoid water bypass, which may result in a weak cup of
coffee, ensure coffee filters fit snugly in the basket
and coffee grounds are evenly spread.
It
is important to properly store your coffee, both before
you brew it, and once it's been prepared.
-
To ensure the freshness of your coffee, exposure to
oxygen, moisture, and outside odours must be minimized.
-
Freshness is optimized by purchasing quantities that
can be consumed within 7 to 10 days after opening.
-
After opening your package, be sure to transfer coffee
to the proper storage container. To ensure coffee maintains
its full flavour characteristics, use an airtight, glass
container, stored in a cool dry environment. Minimize
empty "head space" in the container.
-
Whole beans will begin to lose freshness 21 days after
roasting. As with ground coffee, freshness of whole
bean coffee can be substantially extended if vacuum
packed, to avoid exposure to oxygen.
-
A good rule to follow is not to leave coffee on a warming
element longer than 20 minutes. Prolonged exposure to
heat will cause coffee to burn.
To
store brewed coffee for longer periods of time, transfer
it to a thermal container, which has been preheated
with hot water. This will maintain coffee's flavour
and temperature.
