Roast or brew?
15 Oct · Day 9 of restFault
V60, 15 g to 240 g, boiling water. Fruit and sweetness, but a sour-bitter edge. Not sure if it is roast or brew.
15 Oct · Day 9 of rest
Suspect the boiling water, not the roast. Next test: 93 °C, nothing else changed.
17 Oct · Day 11 of restGood
Water off the boil for 30-50 seconds. The sour-bitter edge is gone, which points to water temperature rather than the roast.
One change at the kettle, no roast spent: the roast was fine.
