As some of you may remember, I got a really cool supply of different hops from a brewer who was slowing down his brewing and wanted to get rid of some stuff. So, I had about 7oz's of Columbus pellets I had my wife put in a vacuum seal bag. I am going to use the probably in the next week or two, so I took them out of the freezer to make sure I have enough as I am making a Morebeer run for some stuff I forgot to order. The bag was still frozen, but the seal might have been broken as they pellets were able to be moved around. Since they were in the freezer, them being open can I still use them? I don't mind either way as I am going to get other stuff too.
Also, they are labeled as Columbus, but my recipe calls for CTZ. I have done a bit of reading and they appear to be the same. Am I right there? Any input is welcomed.
