I don't read all the threads and I haven't been around as some of the old boys and girls, but from the short time I've been on the forum, I have to say I don't recognise what the OP is saying. I don't recall reading about other brewer's methods being rubbished. When a newbie asks for advice, we give the best advice we can: all in one brewers give their advice, three-vessel brewers give their side of the story as do the BIAB lads and lasses chip in their advice. this will lead to conflicting suggestions on a thread and the newbie has to weigh up the pros and cons and decide which way to go. I've seen a lot of arguments against bottling in PETs recently, but no one has been rubbished for doing so. I haven't come across anyone saying buying a Brewzilla is a waste of money either- although it may be in a thread I haven't read.
Nope, I don't get it. And while we're at it, don't buy a bread machine to make your dough, get your sleeves rolled up, my lad, and get stuck in there up to the armpits. Is that rubbishing bread machines and their owners?
