Large Batch

Brewista Tornado Duo Misc pourover by Derek Ku

A larger 1:16.7 batch for the Tornado Duo, shared on r/pourover by D1ckSteele. A bloom and four even pours; the tester found notably better sweetness and a fuller body than a plastic V60, especially on juicy light naturals.

Notes

Medium grind, around 28 clicks on a Comandante C40. Let the water draw down close to the bed between pours; the double-wall glass holds heat, so an unhurried, even pour won't lose temperature.
