I have 3 sets of bottling equipment. One for Sach, one for Brett, and one for sours. While people can argue they have a good enough cleaning regiment, which they very well could have, I dont see it being a big deal to play it safe. In reality this is the cheap side of brewing anyways. For not that much I can buy a bottling bucket, siphon, and tubing (<$30?). My annoyance is purely on the storing of all three rather then the purchase. But in the end would rather spend a couple dollars so I dont have to worry about it, and not run the chance of turning one of my brett only batches sour.
