TEST RESULTS


This coffee threw me for a loop at first! Typically with lighter roasted coffees, I usually increase the brew temp to help ensure the coffee is fully extracted and doesn't taste sour. So I started dialing in at 201F. At 201F it still tasted good, but wasn't quite right, so I increased the temp a little more to 202F. At 202F it started tasting worse. This was really strange. I decided to increase my preinfusion time, and lower my brew temp to 198F. Sometimes an extra long preinfusion time produces the necessary energy to fully extract a lighter roast, and therefore the temp doesn't need to be higher, but actually lower. Bingo! This worked like magic! All of a sudden the flavors went from muddy and barely distinguishable, to crystal clear. I first noticed the bright sweet taste of the raspberry marmalade. It was so recognizable that I was waiting to feel the crunch of a raspberry seed between my teeth. Next I tasted a warm graham flavor that reminded me of toasted oats. Lastly I noticed a bittersweet chocolate flavor that lingered and melded with the initial raspberry flavor. I really enjoyed this combination of flavors. Sometimes a little bit more experimentation is required to really taste everything a coffee has to offer. It was a good reminder to paint outside the lines, try new things, and always follow your taste buds.
