hello all, new poster/homebrewer here.
I brewed a mexican cerveza for my first attempt, after about 4 weeks after bottling, it was excellent, held it's head all the way down the glass and was crystal clear (as long as it was carefully decanted out of the bottle)
Next batch was a german pilsner. I seem to be having a bit of a problem with this, brewed as per instructions, then bottled with half tespoon of brewers sugar and capped. Left for 4 weeks, opened one bottle, and it basically turned to froth all over the sink and didn't taste the best. I left the bottles for another 6 weeks, just opened another bottle, and it's done the same, out of a 750ml bottle, I can just about manage to get 1/2 pint of lager out of it, the rest is a very active froth that ends up in the sink. It doesn't taste the best, and looks even worse. The looks I'm putting down to the fact that with the explosion of bubbles, it's disturbing the sediment, but the non-lager taste it's got is causing a problem, still tastes quite yeasty
Is this just a case of leaving it for longer in the bottle?
cheers for any advice
