LONGMONT, Colo. — Left Hand Brewing is recalling 20,000 cases of its most popular beer.
The company said while its Milk Stout Nitro is safe to drink, a foreign yeast got into the mix. When the bottle is flipped upside down into a glass as recommended, it may overflow.
Left Hand said because the yeast looks similar to its own ale strain, it was not identified until the bottles arrived in the market.
Affected beers have best by dates of Oct. 16 to Feb. 28.
The brewery is also pulling Milk Stout Nitro included in its Mountain Mixers variety packages with codes 130-B to 242-A.
Left Hand is asking consumers to return the affected beer to the store where it was bought. Replacement beer will be available in about six weeks.
