Looking for the juciest, frutiest coffee rn.
I saw a video by Lance Hedrick recently where he's sorting out bad beans before grinding, and then sifting the chaff out of the grounds after grinding, and says that it makes a big difference and even showed a blind test where the differences were pretty apparent, so I had to try it out. Here's the video:
Picking out beans is sort of tedious, and I haven't spent too much time on this: I mainly toss the really deformed looking ones, as well as the ones with empty shells. I haven't found too many light-colored quakers yet. This also feels wasteful to the cheap person in me especially for a really expensive coffee.
Sifting out the chaff after grinding is also tedious and messy. Basically you shake the grounds so that the chaff migrates to the top, and then blow across the top of the grounds to remove the chaff. I do this over a large plate, but a good amount still ends up on my counter. No need to blow very hard too: like maybe half or quarter of what you might use to blow out a candle: the chaff is very light and blows off easily. Anyway, repeat this as many times you care to: I do it until my water's finished boiling.
So what are the results? Well I think the cup it produces is less astringent, more round in mouthfeel, and a little sweeter. You can also steep the chaff you collected above in hot water, and taste the chaff tea that produces to get an idea of what off-flavors you're removing. To me, it tastes like overextracted tea with that astringent kind of taste you can get from black tea.
I've noticed that different bean varietals and roast levels will produce different levels of chaff. The amount of chaff for the coffee I tried (a Colombian Gesha from Paradise) is on the low side. I've seen light-roasted Ethiopians throw off tons of chaff, and I imagine this technique will be more effective on those kinds of beans.
Has anyone else tried this, and what did you think?
Suggestions for a brewer to use at work? Doing dishes is a pain in the neck there so I'd rather not doing something I need to rigorously clean after every use like a French press or Aeropress. Just go for another retention dripper (Clever etc) like I use at home?
