The way these breweries print their dates is always subject to change. We have determined these dates from the best of our abilities. Although most will be accurate we cannot guarantee total accuracy. Please let us know if you recognize a change in their dating process so we can update our records.

The “10” denotes the year of production, and the three numbers after mean that the beer was brewed on the 84th day of the year, or today, March 25th. The letters and numbers after that indicate a brewery and packaging line.

Gritty McDuff's: They use a Best if used before date. From information we have seen the brewer states that on their 12 ounce bottles they have a Best if used before date. It is typically on the left side of the label. You'll see a notch for a month and a year.
Guinness: They use a coded bottling date of day, month, year. The month is a letter so 16B9 is 16 Feb 99. Previously, the date code was a reversed date like 79 10 21 for 12 January 1997.
