), I set out to test several common methods for coffee storage in the hopes of finding out if there really is a “best” way to store coffee, or if it is all just superstition.We are very familiar with the aroma and flavor.-In a sealed plastic coffee bag (with gasket) – no light gets in [note: we didn't use Velton's Coffee in this test, and this wasn't even the bag we used.-In a ziplock bag, with most air pushed out, wrapped in a brown bag, in the freezer – no light exposure, minimal residual air moisture in the bag to begin with [note: one of the assumed reasons for saying that freezing coffee is bad is due to the exposure to moisture condensation that can happen in a freezer, by removing air from the bag to begin with, there is little moisture left to condense on the beans].Here are some initial impressions from the 7 cups that were tasted (1 of which was the freshly roasted batch).It was noted that the two glass jar beans and the fresh roast smelled the best.I believe our overall assessment of aroma was that the less air contact with your stored coffee – or, the more airtight your seal – the better aroma you will find (which is not much of a surprise).The open-air storage – which was thought to be the worst, and which may have had one of the less pleasing aromas, was not the worst tasting.The coffee stored in a paper bag was remarked by one as the least favorite, and we discerned very little difference between the coffee stored in a regular paper coffee bag, and the coffee stored in the plastic bag with gasket.As I mentioned before, it is clear that these are 4-week-old coffees when compared to fresh roasted coffee – however the test has demonstrated that there are indeed better ways to store your coffee during those 4 weeks.It should also be noted that the freezer coffee was stored in a sealed plastic bag that had most of the air removed, and was also put inside a brown paper bag to block incidental light (due to opening the freezer at any point throughout the month).There was little to no difference between the airtight gasket bag and the regular brown bag – this, along with the surprising mediocrity of the open-air coffee, perhaps suggests that external air exposure is not the worst thing for your coffee (though it obviously has an effect).Here is the order of best to worst coffee storage methods, in terms of flavor (not including fresh roast, of course):.*In a ziplock back, with most air pushed out, wrapped in a brown bag, in the freezer – no light exposure, minimal residual air moisture in the bag to begin with.**In a sealed plastic coffee bag (with gasket) – no light gets in.**the brown bag and the plastic gasket bag were almost identical in flavor. .
