I was excited to drink them (RIS is one of my favorite styles), and they were good but REALLY boozy (11.5%). At first I just expected that's what a homebrew RIS to taste like. After I drank the one that aged, I was kinda angry that I didn't save any more. The boozy flavor subsided so much and...
My second brew was a RIS and I was dumb and drank the majority of them with my buddies as soon as they were carbonated. Last month I found one that was hiding in the pantry for almost a year.... I really wish I would have waited longer on the others.
I bought 100 ft of 3/8" vinyl tubing from coleparmer.com for about $20. Now if it still looks nasty after I rinse with sanitizer i just toss it and cut a new length.
