I brewed my last full cup of coffee with my Starbucks medium roast beans this morning, which is noteworthy only because this was my first foray into grinding beans myself. I’ve had the bag since last winter, and started out using a blade grinder and a drip coffee maker. Needless to say, the results were inconsistent — some cups were good, and others were not so good! I soon switched to a good quality burr grinder and a French press, which produced much better results. Somewhere along the way, I started measuring beans and water by weight rather than volume. Then, I upgraded from a cheap electric kettle to an expensive one that lets me heat water to a specific temperature, and I added an Aeropress. I now brew most of my cups with the electric kettle, burr grinder, scale, and either Aeropress or French press. But the point is, these beans have been with me through the entire progression.
I brewed this recipe with the Starbucks beans yesterday and today. Yesterday’s cup turned out pretty good, but ever so slightly bitter. Today’s was great. The difference: yesterday, I dumped the beans into the grinder directly from the jar, and a lot of “fines”, husks, and other smaller fragments from the bottom of the bag got mixed in there, which I suspect imparted a little bit of bitterness. Today, I made sure that only whole beans got into the grinder, and the result was a better cup.
There are still a few beans left at the bottom of the jar, which I’ll probably grind up along with the fragments and use for cold brew. I guess it won’t be too long before I’ll be looking to buy some new beans.
