I'm trying to figure out if I'm doing stuff correctly. According to David Line's book, you need to boil the wort until the proteinous matter coagulates into small matchstick-head-sized lumps. I never seem to get that. Here's a collection of pictures taken at 5 minute intervals towards the end of my boil (90' in total), so from about 50 minutes onwards until flameout.
Does this look like I've boiled long enough. The protein flecs don't seem to be the size of matchstick heads.
Would it have benefitted much if I'd have let it boil more, or do you think that break is sufficient?
As for the wine glass - it seemed to make sense. It's a small glass that you can hold by the stem so that you don't burn your fingers on the scalding wort!
