Brewer Wadworth is expected to launch a new 4.1% ABV stout, Corvus, into the on-trade later this year.
The stout, which takes its name from the Latin word for "raven", will be available in 30-litre kegs.
"We have noticed that publicans struggle to maintain the quality of stout in the more widely available 50-litre format, and therefore have produced a smaller keg in order that throughput is faster and quality can be maintained for the lifecycle of the keg," said Wadworth brand manager Christine Evers.
Pubs with a higher turnover can buy the beer in 9 gallon kegs.
The beer has aromas of malt and coffee and is brewed from a blend of roasted barley and toasted malt.
The following 10 Wadworth pubs will be stocking the stout for free tasters for the rest of this month. They are:
• The Crown, Devizes
• The Goat & Tricycle, Bournemouth
• The Red Lion, Lacock
• The Cleveland Bay, Chandlers Ford
• The Victoria, Old Marston, Oxford
• The Linden Tree, Gloucester
• The Pheasant, Chippenham
• The Penny Farthing, Bristol
• The Barge, Seend
• The Wheelwright Arms, Reading
