Light Strike

[Bevitron]

I've read a couple of posts mentioning light strike and how this can be a problem when conditioning in clear glass bottles.

Is this something to worry about when the first fermentation is taking place. I've got a Coopers European Lager on the go (first ever brew) and it's currently on my landing happily bubbling away. Was wondering whether I should be shielding it from the light?

Cheers

Yep you should hide it from direct light.

Just stick them in a box or a black back and they should be ok.

My FV is sat in the kitchen an ive never had the beer go funny. I think that its actually direct sunlight that causes off flavours and can "skunk" the brew. If in doubt tho you could always put a black back round it or cover it with a towel ^^

I don't know about you but my FV isn't very clear so light strike wouldn't be a problem and I would be more worried about heat if it was in direct sunlight.

Not worth the risk if you can help it.

This seems to be more of an issue with all grain or extract brewing when the bitterness is produced by boiling hops (pellets or whole flowers). Kit manufacturers tend to use isomerised alpha acids which aren't affected in the same way as alpha acids from whole hops.

So basically good practice to hide your beer from the sun/daylight but not absolutely nessacary for most kit beers.

Cheers guys, very helpful. Have wrapped it in a towel to be on the safe side.
