Paint thinner

I just tasted my japanese lager after 2 weeks in the bottle and I seriously cant drink it. It tastes like paint thinner or vodka or something. It's only 7% alcohol. It wouldnt make it taste that bad would it? I know you can get paint thinner taste from fusel alcohol at high temperature fermentation but I fermented this in a fridge at cold temperatures. Where the hell did this taste come from? I hope it disappears because I dont want to flush 20 liters of beer away.

Did you do a dicetyl rest?

It is possible that with very light lagers that you need much more aging for it to mellow. Since the taste is very light it does not cover up odd flavors like an ale would.

Lagers ferment at cooler temperatures too. Too high of a temperature in your primary could cause lots of off flavors.
