I admit I've become a bit obsessed with fresh produce in the last couple of years. There is no doubt that the wonders of modern technology have enabled us to have fresh produce all year round, no matter what the season, but if you think seasonality no longer matters for produce you're kidding yourself. Tomatoes are the perfect example. This time of year, anyone in NYC would be hard pressed to find a really fresh tomato. Of course, you can find them in your supermarket and of course they look fresh but the taste can't even compare to the mid-summer tomatoes you can pick up at the farmers market.
Since coffee is a produce, it also has seasons. Getting fresh coffee in season is definitely not as easy as getting a tomato in season but depending on your roaster, you can certainly get fresh roasted coffee that's in season.
The seasons for coffee differ based on its origin and the seasons shift based on the growing conditions in a given year. I found a great little post on coffee seasonality on the Counter Culture website. Enjoy.
