From what point in the brewing process do you need to be concerned about light skunking the beer? Only after the fermentation has started? Or right from the start?
From doing a bit of research on the net, it seems even a short period of light can cause the beer to skunk, but obviously you need some light for seeing what you are doing during the brewing and bottling process. I try not to do any of this during the day (so I'm only using artificial lights), but the exposure for this short a period even something I should be concerned about?
Also, as I'm brewing this in a garage with windows, I've ended up putting a large wooden barrel over top of my brewing container to block out the light completely during the fermentation process. Is this a reasonable approach?
