How much sunlight does a beer in green bottles need to become light struck? How can they get light struck in carboard 4 packs, in cardboard case boxes?
I have a homebrew I put in Grolsch bottles, back in the 4 packs, in the closet. We open the closet to grab some coats and stuff and then nclose it right away. Now I am worried; they way you guys talk it seems like 5 seconds of sunlight and the beer is trash.
