So I had a Festbrew Brown Ale I recently finished in bottles for over three weeks. I stored one dozen in a box in my kitchen and the rest in a cabinet above my fridge. I transferred the beer from the box into the fridge and it tastes great... good carbonation, good flavour, all good. However, the beer I've stored in the cabinet above my fridge tastes flat and gross... The temperature in the cabinet is not hot... feels like room temperature, but is it possible that it has spoiled?

If so, is there any way to salvage it or is it wasted?

Thanks!

Try keeping it in a warm place and try to resuspend the yeast in the bottle without shaking the shit out of it,

I wonder if the fridge over heated the beer when it was in self defrost and then cooled down. The beer was like warm then cool, warm then cool. This may be a dumb theory though.

I think the beer in the cupboard was probably just too cool overall and hasn't carbonated. As Tony said, if you agitate it a little to re-suspend the yeast and move it to somewhere warmer it will probably be fine in a few weeks.

You should send it all to me for proper analysis. If it is deemed worthy for mass consumption, there may be enough left over to send back to you.

Great thanks guys! I'll give that a try.
