What does the 06 13 mean on a Guinness glass?

Answered by Joseph Vos

The markings “06 13” on a Guinness glass refer to the date of manufacture. To understand the meaning behind these markings, it is important to delve into the history and evolution of glass markings used by Guinness.

In 2006, the National Standards Authority of Ireland (NSAI) introduced a new marking called the “pint” mark. This mark consisted of a circle with two wavy lines, with the word “PINT” written between them. Additionally, it featured a year mark indicating the last two digits of the year, and a three-digit batch code on either side.

The purpose of these markings was to ensure the accuracy of the pint being served and to adhere to regulatory standards. By having a specific mark for pints, it helped to prevent any confusion or misrepresentation regarding the volume of liquid being served.

However, as time went on, the NSAI pint mark started to be phased out in favor of a European standard marking known as the “PINT/CE logo stamp.” This new mark features the word “PINT” along with the “CE” logo, which stands for Conformité Européene (European Conformity).

The transition from the NSAI pint mark to the PINT/CE logo stamp was likely driven by the desire to have a standardized marking system across Europe. This would make it easier for breweries and establishments to comply with regulations and ensure consistency in serving sizes.

Now, coming back to the specific markings “06 13” on a Guinness glass, it is important to note that Guinness has been using these markings to indicate the date of manufacture. The “06” refers to the year, while “13” indicates the month. In this case, it would mean that the glass was manufactured in June 2013.

By including the date of manufacture on the glass, Guinness aims to ensure the quality and freshness of their product. This information can be useful for both consumers and establishments to track the age of the glassware and assess its suitability for use.

The markings “06 13” on a Guinness glass signify the date of manufacture, with “06” representing the year and “13” indicating the month. These markings are part of Guinness’s efforts to maintain quality and adhere to regulatory standards.
