Hi, I've brewed a few lager beers that have unintentionally ended up being about 3.5-4% ABV due to high mash temps and poor efficiency, as I dial in a new system. I have found the beers tasted really good initially, but lost their flavour as they got up to my desired carbonation level (¬2.4 volumes, 37F at 10PSI). I think the beer is overcarbonated, not because there is much foam, but because hop and malt character is gone.
I suspect the lower ABV means that the CO2 overwhelms the beer at lower volumes than it normally would. However tables and formulae don't seem to consider this. I guess most styles are normal to high ABV and have higher recommended volumes of CO2. Perhaps I should be targeting 1.5-2 volumes for a low abv beer such as this. thoughts?
