Default skunky beer

So the last batch of blonde ale i brewed tastes very skunky. It fermented in primary for 1 month and secondary for a week. The fermenters sat on my tool bench in the garage were afternoon sunlight came in direct contact with them every day. Could that cause skunky taste or is it just to green still? Its been chilled and kegged for two weeks now.

Sun light interacts with hop oils to produce skunkyness. Please keep beer out of light.

You hit the nail on the head. Find some way to protect your beer from light.

A t-shirt can help, but UV can still penetrate if they're sitting outside. Ever get a sunburn thru a t-shirt? I definitely have.

When I use a t-shirt over my carboy it's to protect against short bursts of indoor fluorescent light. If you have sunlight streaming through a window onto the fermenters, I'd definitely try to ferment somewhere else. In addition to skunking, you could also be causing temperature swings.

If you're using glass, try fitting a cardboard box over the fermenter or putting a heavy blanket, towel or sweatshirt over it. Or just switch to plastic buckets.

Some skunky beers are pretty good though, Beck's & St Pauli Girl have that skunk smell, and they are great beers !!........

Use tin foil. The same one that you can make anti-mind reading caps.

+1 on the tinfoil. Or just find a way to store it under the work bench. there are threads of people that have made fermentation chambers under their benches.

I take a black, heavy-duty trash bag, cut one bottom corner off so that the neck of the carboy can just fit through the hole, slide the bag upside down over the carboy with the opening of the carboy poking through the hole I just cut, and secure the bag around the neck of the carboy with a rubber band...and sanitize everything.
