AB InBev is running a dual font trial for Stella Artois offering cold or extra cold variants.
The trial which is running in a limited number of pubs until the end of the month will be reviewed for possible roll-out.
A spokesman said: "AB InBev UK is constantly looking at ways to develop and innovate within the beer category in order to meet changing customer and consumer needs.
"We have been running a limited edition trial of a new dual cold dispense font for Stella Artois 5%: "froid" and "tres froid"— which is served slightly below regular serving temperature.
Trials continue until the end of the month in a small selection of on-trade outlets, following which, we will evaluate the results."
