For me, the greater question is why there's no standard storage method. It's the same product sold around the world, but there are so many passionately differing opinions on how to store it properly.
Where's the Scopes Monkey Trial for coffee storage?
I spoke with some local roasters and did a little research of my own to see if I could get any clarity on this topic.
Were coffee more démodé in Denmark than say, murder, Hamlet's famous soliloquy might have gone like this: to freeze or not to freeze. That is the question, but the answers depend on how much coffee you have and how long you want to keep it. Rick Milton, owner of Northwest Coffee Roasting Company
recommends an opaque, airtight container at room temperature: "You don't want sunlight hitting the coffee. The sun heats up the coffee and starts to degrade it."
When I asked about freezing coffee, Milton said that there is always concern about the freeze-thaw cycle and the condensation that it creates. Caramelized sugars and oils in the coffee start to lose their punch
-- very quickly in at least one drinker's opinion
Gail Maher, one of the owners of Shaw's Coffee Ltd.
, doesn't agree: "Those oils aren't going anywhere." Maher recommends freezing your coffee as soon as you get it home. She says that, in her opinion, coffee is like any other agricultural good; therefore, freezing is the tried-and-true method to maintain its freshness.
Remember my argument from earlier? It was over this point. My friend was adamant that beans should always be frozen. He went so far as to accuse the coffee-industrial complex of a global conspiracy against the consumer -- lying about the merits of frozen coffee to save on shipping and storage costs. He's not alone. A "Coffee Talk" article
on Shaw's Coffee's website states, "Additionally, such opinions are very self-serving for coffee roasters and distributors who typically maintain coffee for long periods on grocery store shelves at room temperature."
There is an interesting point here: Were freezing the "best" way to store all coffee at all times of its life, the costs to larger companies would be astronomical. Consider Starbucks: It labels bagged coffee beans as "good" for up to months at a time. Last week, I saw a bag of unrefrigerated, non-vacuum-sealed Starbucks coffee that was supposedly good until January 2010! If that coffee is still fresh then, you're drinking the coffee equivalent of SPAM.
The only time I've ever had something remotely close to an argument with another coffee drinker was over how beans should be stored at home. How often have you heard of someone storing their beans one way and thinking, "Oh god, they're ruining that coffee"?
