Getting frustrated so need some help. Brewed a mexican lager (Mexican Logger Clone) and the beer is gassed, has head retention but is drinking flat. It's as if the CO2 is coming out of solution straight away. The beer is force carbed and was accidentally carbed too high @ 1.1 bar should be 0.9 bar. Interestingly I had this problem with a ginger beer that I brewed last year - just wouldn't hold any gas as well though it was force carbed correctly. For the lager I brewed with a very low mineral content in the water (water varies greatly here but I test before very brew and adjust). Also only other anomaly was that my brew buddy managed to mix the star san at way too high a ratio (2.5ml to ~700ml). Everything else as it should be. 15 other brews with no issues. Sorry for the lack of conversion but it's late here. Help pls!!!
