Help! My Hario Mini Mill is giving me a lot of fines. : Coffee
My Hario Mini Mill is giving me a lot of fines. () submitted 3 years ago by RxDealer88. I got a mini mill about a month ago for use with my V60. I did the tape modification right away. It seemed to be working fine for the first few weeks but lately I get so many fines 350g would take 4 min to drip through.
