買了幾瓶美國鐵錨啤酒，保質期到底是多久？

01-28

一些店家說是保質期一年，另一些店家說保質期是兩年，而且瓶身上也沒有裝瓶日期，很是莫名。畢竟裝瓶日期是很影響口感的。

What do the codes on the bottles mean?
The date code currently being used by Anchor Brewing Company (post-October 1991) replaces the clock-face that used to show the bottling month as one of 12 small notches around the main label. A three character code is now included on the new back label of the bottle. The code works like this:
The first character is always numeric and represents the last digit of the year. The second character is always alpha and represents the month by using the first letter of the month unless that letter has already been used:
January: J

February: F
March: M
April: A
May: Y
June: U

July: L
August: G
September: S
October: O
November: N

December: D
The third character in the code is either alpha or numeric and tells the day of the month. The first 26 days are represented by the alphabet with the remaining days listed as:
27th through 29th = 7 through 9
30th = 3

31st = 1
An example of a date code would be: January 20, 2012 = 2JT

根據Anchor Brewing的官方介紹

瓶身上的三字代碼表示了生產日期

第一個數字是年份 201x

第二個字母是月份

第三個代碼 A-Z的話是1~26日 27-&>7 28-&>8 29-&>9 30-&>3 31-&>1

所以2JT就是2012年1月20日生產。

保質期的話可能還要瓶身找一下？

建議IPA類越早喝掉越好（Stone的Enjoy After系列這種類型除外）

其他按照常理是12個月-24個月，Porter、Stout、Barley Wine可能120個月應該差不多或者更長。

以上。

啤酒大多數的保質期的是一年，超過六度的一般可以存放一年半兩年

但是，老美的習慣是三個月，所以趕緊喝了吧
