I'm curious about something; I know that aluminum is sort of universally frowned upon in the metal community, but what are the real disadvantages of using an aluminum brew kettle. The reason I ask is because there is a Vietnamese supermarket in my city that sells these ridiculously large aluminum pots for what would be dirt cheap compared to stainless or enamel. I've got one of the smaller ones that I use for cooking, and they are pretty well put together by the good folks at chue chin hua limited partnership, but I wanted to get some opinions before I plunk down some money and bring one home.
