I poured out my first 3 Chemex brews for 2 weeks straight, then a guy at a shop in Portland changed my mind
I was sure my $18 blade grinder was fine for pour over, so I dumped the first three Chemex batches down the sink because they tasted like paper and mud. Last month a barista in Portland let me brew the same beans twice, once with my grinder and once with a hand grinder, and the second cup actually tasted like the blueberry note on the bag. Now I want to know if anyone else switched grinders and got that big of a jump, or did I just get lucky with that one bag of beans?
Wait, you dumped three whole batches down the sink for TWO WEEKS and just kept buying more beans? That is like 6 to 8 bucks of coffee wasted every single morning and you just shrugged and did it again the next day. The paper and mud taste was your blade grinder kicking out dust on one side and chunks on the other, so the water hit both at once and you got the worst of each. You did not get lucky with that Portland bag, that blueberry was sitting in your beans the whole time and the blade grinder was hiding it from you. It still blows my mind that you drank sink coffee for 14 days before somebody showed you the difference.
Guilty as charged over here, I used a blade grinder for almost a year before my wife got me a Baratza for my birthday (she was tired of watching me sulk over muddy coffee every morning). The jump was real for me too, mostly because the blade grinder was throwing a mix of powder and boulders into the Chemex, so the water would race through the big chunks and stall on the dust. Once the grounds were even, the flavor got way clearer and I could actually pick out notes instead of just tasting brown. That Portland barista did you a solid, but I do not think it was luck with the beans, it was the even grind letting the blueberry actually show up.
