Catering equipment dealer Stephensons has put together a temperature experiment for the traditional British Lantern tankards it sells.
Carried out last month by industry analysis and training expert Brewlab, the test is said to have revealed that the vintage design keep beer and ale over 40% colder than traditional pint pots, which should improve drinkability.
Comparing the temperature warming rate between identical liquids in two different types of glassware; the 10-sided Lantern Tankard with its prominent handle, and a nonic pint glass, the 50-minute experiment saw the drinking process mimicked whilst the pint glasses were held by the handle for the tankard, and around the glass for the nonic pint pot.
The temperature of the liquid was recorded every 3 minutes, with a noticeable difference said to be found between the two glasses. After the 30 minute mark the nonic glass measured in at 20°C, compared to the tankard’s 14°C. By the end of the test, the Lantern finished at 17°C – cooler than the nonic’s final reading of 24°C.
Henry Stephenson, MD at Stephensons, commented: “We recently revived the 1920s/1930s lantern shaped tankard in a bid to bring it back to Britain’s bars and pubs. The glass not only showcases the liquid but also, as proven in our temperature test, improves the consumer’s entire drinking experience.
“Beer is most commonly preferred at a cooler temperature, and the Lantern Tankard has shown to be the glass of choice to enhance that experience.”
Alison Hedley, laboratory manager at Brewlab, added: “We ran the experiment in duplicate to eliminate any anomalies, and were surprised that both tests showed such a difference in temperature between the two different glassware.
“To ensure the experiment was statistically valid, we followed all procedures requested, ensured the glasses were the same temperature at the start point of each assessment, and carried out the test within our controlled laboratory facility using UKAS accredited thermometers.”
