I may have made a big mistake when dry hopping, I read somewhere that some use marbles or ball bearings to weigh hop bag for dry hopping. Well, I used a large ball bearing, I boiled it with my hop bag for 10 minutes and then submerged them into a star san solultion. I bottled today and I noticed that the ball bearing turned black prolly from the acids from hops. Any danger? Dont seem to have changed the taste of My IPA.
