So tonight I called my brew partner over to bottle our American amber ale that we brewed 3 weeks. ago. We made the priming solution and racked the beer and sanitized and cleaned all of the bottles...but when I went to grab the caps..(which were the leftover from a previous batch) they were covered in rust..I sanitized all of them last tine and took what I didn't use and shoved emm in a plastic bag..we had to use them cause everything was already ready..my question is: am I okay? Or should I go to the brew store tomorrow and get new ones? I'm afraid if I recap ill lose carbonation.. Thanks!!!
