I am looking to trade in the near future for some vintage BCBS and I want to clear up a few things. 1. What is the specific bottling date/s for 2007 bCBS made in PvW barrels? 2. What is the last year bottles used twist off caps? 3. Was 2009 the only vintage that came in 22oz bottles? It was also on 12oz I assume? 4. Are there any specific bottling dates from any vintages known to be infected? If you have any other noteworthy and nfo about vintage BCBS please leave it here, and thanks!
