Hop Sock Weights? in DIY Brewing Blether Posted October 19, 2019 · Edited October 19, 2019 by Journeyman I'm new to all this - figured to begin with Coopers cans and then start hopping a lager can to experiment. I was looking at the hops balls from Kegland, says stainless and they're Aussie so hopefully should be decent steel? They also have a hop tube that I thought would be good. Edit: Page says... "Specifications: Made from: 304 Grade Stainless Steel (for both bomb and tube) But I don't want to lose brews to rust flavouring. What do you put the hops in? About all else I have seen are nylon or polyester bags.
