I am absolutely perplexed about something. I made an acerglyn. Honestly I wasn't impressed with the flavor when it finished, it batch aged for almost a year in a one gallon carboy then I bottled it in hopes that aging it further might help. I had about four bottles worth all in my basement which stays around 50 to 55 degrees year round. They have been in the bottles for about six or seven months and I went into the basement after work to dig out some gardening tools to find that ALL four blew their corks today. I know it happened today because I was in the basement last night and it had not happened yet. So my question is why? Why after sitting a year in a carboy then sitting six months in bottles did they suddenly decide to blow their corks?
