Cans of two limited edition beers produced by the Southern Tier Brewing Co. near Jamestown have been recalled because of worries they could burst open.

Wegmans issued a recall Monday for packages containing 16-ounce cans of Southern Tier Brewing Pumking Nitro and 12-ounce cans of Southern Tier Brewing Blackwater Nitro Chocolate Milkshake.

The Wegmans notice said the recall is "due to reports of inconsistent nitrogen gas pressures that may lead to package integrity issues, including bursting cans."

There have been no reports of actual cans bursting -- at least in the Syracuse area, according to Carissa Monahan of the Branching Out Bottle Shop in Camillus’ Township 5. She received notice of the recall this morning. Branching Out still has a case of the Pumking Nitro.

Monahan said she was told the cans could be “over pressurized.”

Both products are limited, seasonal releases. Both contain nitrogen, often used by brewers as an alternative to carbon dioxide to create a creamier level of carbonation and cascading bubbles..

Southern Tier, in Lakewood, Chautauqua County, is one of Upstate New York’s best-known and most highly acclaimed craft breweries. It frequently uses nitrogen to carbonate some of its specialty beers.

The recall does not affect other versions of Pumking, which are pressurized using carbon dioxide, or other beers in the brewery’s Blackwater series, which often contain nitrogen.

According to the Wegmans notice, the Nitro Pumking has the UPC code 81601402113. The Chocolate Milkshake has the UPC code 85375900053.

Update: On Wednesday (Nov. 6), Southern Tier issued this statement:

“At Southern Tier, quality craft beer has been our priority since we opened our doors in 2002, so we take any concerns about our products seriously. In the past few days, retail customers and consumers have seen some of our nitro beer cans bulge and, in a small number of cases, burst. We looked into the issue and found that a couple lots of Southern Tier Pumking Nitro cans (16oz) and Southern Tier Blackwater Chocolate Milkshake Nitro cans (12oz) had slightly too much nitrogen – the ingredient that makes Nitro beer so smooth and creamy. While a small change in the amount of nitrogen shouldn’t affect the quality of the beer, it can - along with environmental factors such as temperature variation – increases internal pressure on the can, causing it to bulge or, rarely, burst. The issue happened while we were implementing and refining some new packaging equipment. Once the problem was identified, it was corrected for future runs. Out of an abundance of caution, we asked our wholesaler and retail partners to pull impacted products from their warehouses and shelves. The issue impacts only the four-pack of Pumking Nitro cans and the Blackwater four-pack Chocolate Milkshake cans. If consumers have these products in their possession, they should throw them away and call 855-274-0047. Representatives will collect the information we need to issue a full refund. All other Southern Tier and Blackwater Nitro brands, including Crème Brulee, which is currently shipping to the market, have passed our quality checks, and are ready to enjoy. We sincerely apologize for this issue. As always, we continue to look at any and all additional steps that we can take to improve the process and quality of all Southern Tier brands.”
