A while back I sanitized a bunch of bottles with StarSan, gravity-drained as much foam out as possible, resealed them (put the caps on to slight firmness), then stored them shut.
I was expecting to use them in ensuing batches, but with some major life-interruptions, I unexpectedly brewed far less frequently in the past 6 weeks.
Are these bottles still good to use now, 6-8 weeks after sanitizing? They've been stored shut the entire time. There is a tiny bit of liquid residue in each that was the starsan foam I left in them when capping.
Sure, I could just re-sanitize... and perhaps should... but I'm lazy. Do I really need to?
How long would you let a pre-sanitized bottle store closed and still feel good about using it?
