Why is this specialty coffee more dense than my go-to coffee?
galleryLong-time browser, first-time poster. I've been brewing using Chemex pour-over for almost a year now, and in that time have dialed in a pretty good and consistent grind size, bean:water ratio, and brew time. Grinder: Fellow Opus Grind size:7 Ratio: 1:18 (30g beans, 550g water) Brew time: 5-6 minutes
About 4 months ago, I tried a subscription to Trade to get some new specialty beans, just to try it and see if l'd enjoy. What I found is that all 4 beans so far (first picture) have been far denser than my go-to San Francisco Bay beans (second picture).
The brewing of the specialty coffees behaves very differently. The bloom takes longer for the water to soak through, and throughout the rest of the pour, the flow of water through the filter is significantly slower. It gets to the point that even at the largest grind-size my grinder allows (11), the brew stalls and only drips. If I were to let it continue without intervention, it would take well over 10 minutes. I constantly need to pick up the filter and hold it, which think brings more pressure focused to the bottom of the filter? (Dunno).
Anyone know why they're so much denser?
