Gday Brewers. Was hoping someone might be able to help me troubleshoot reasons why my kolsch is coming across too tart/Acidic. Is this a kolsch thing? I'm guessing not but it's obviously a flaw in my brewing of this recipe- https://www.brewersfriend.com/homebrew/recipe/view/717899/k97-kolsch . Now that to me is too much lactic Acid? Too low final PH (but that should be negligible as yeast play their part in dropping PH). I used 3ml of lactic acid to hit the brew calculators PH of 5.3. My only other explanation and I'm leaning heavily toward this too high carbonation resulting in high carbonic acid taste in beer almost a bighty back of the throat kind. I've found letting the kolsch sit and warm up some brings out the malt more and lessens the bite I think I'm up for a new regulator... The preassure climbs sometimes ever since purging beer through it ! New dighapram who knows maybe youse do...? Heres the beer in question cheers for any help!
