A: We recommend against using shallow plastic tubs as coolships. Most plastics are not food grade. And those that are may not be food grade at boiling temperatures. Also, boil kettles provide suffficient cooling rates as long as outdoor temperatures are cold enough. If you are looking to mimic commercial processes, then a homebrew-sized boil kettle has a surface area:volume ratio more similar to commercial coolships and will have a cooling rate more comparable to commercial producers. See the [[coolship]] page for more info.

We have two great pages that help you brew your first kettle sour. See the [[Sour Worting]] page, and the [[Lactobacillus#Culture_Charts|Lacto Culture Charts]]!
