A workmate brews. He makes weird, funky beers including super high alcohol content ginger beers. IMO most taste like shit. His partner has some sort of doctorate in something to do with biology. She has told him the yeast is yeast, so he uses the yeast from bread packs in his beer. I told him he is wasting his time and its probably the reason why his beers taste like cat’s piss. Who is correct, the partner who says yeast is yeast, or me .. who says yeasts ain’t yeasts?
