LMSC So, going back to Clever and V60, I wonder if I should be brewing at longer ratios; say 60g/l than the usual 65g/l for V60 and perhaps at 70g/75g a litre in the case of Clever keeping their grind size unchanged.
But you brewed the cupping at 65g/L? I guarantee you that the cupping was weaker than the V60 at the same ratio. So, it suggests to me that it’s not the ratio that is the issue. First off I’d brew the Clever at the same ratio as the cupping, same grind, leave it 30min.
V60 relies on flow through the bed to brew, so there is always some particulate making its way through the filter, so I’d try going coarser on V60 and see if the muddled flavour improves, before everything turns green/underdeveloped/sour.
You say the grind is mid way in the drip range, but we don’t actually know what this is in any objective sense.
