i have just brewed my 17th batch on my Grainfather, with generally excellent results .
A good mix of ales and porters, but with less success with lighter beers, (lighter coloured not low alcohol).
2 batches, number 7 and number 17, both variants of a pale ale brewed several months apart have a distinct aftertaste which I don’t believe was present in the wort, but showed up during fermentation.
I am convinced there are no issues with sanitation, but can’t put my finger on the cause.
Looking up types of off flavour, it is difficult to be certain without a reference, but I am leaning towards chlorophenols.
I checked my local water report, no chloramine is used, and chlorine levels are typically 0.35ppm (with a high of 0.6) which seems quite low.
Would love to know if there was a way to confirm what the off flavour is, without resorting to expensive testing.
Grateful for advice / suggestions
