Pre-ground Coffee Aging Test

In answer to the oft posed question 'can't I just use pre-ground coffee from __[insert your favorite store/roastery/cafe here]__?', we have held an aging test. We're big on freshly grinding your coffee before each shot, as pre-ground starts to dry out (even in air-tight containers) within the first 24 hours. To show you how the shots degrade, we dialed in and ground a bunch of coffee, then pulled a shot the day of for baseline purposes. We then pulled shots 24, 48, 72 hours and 1 full week later to show how the shots measured up -- and to give our unequivocal vocal and facial feature responses to their flavor. Yowza! Watch Gail as we go through the initial testing and then check in throughout the subsequent week.
