Trillium Brewing Co. is telling purchasers of its fruity Daily Serving: Blackberry, Plum, & Raspberry beer to keep the cans cold, not just because that means the best taste but because otherwise the cans might, as Trillum says, burst.
Trillium reports at least three customers have had cans go kablooie of late because they stored them at room temperature.
The problem, Trillium says, is yeast. Trillum says it does its best to get rid of yeast before cans go out for distribution, and estimates it eliminates 99.9% of the wee beasties. But leave just one yeast cell in a can of warm beer mixed with sugary fruit and you're looking at a Malthusians yeast growth explosion that can then be followed by a bursting can as a now rapidly growing yeast colony yums up all the sugar and excretes, among other things, carbon dioxide.
We don't want anyone to have to clean up a mess and advise that you store these cans in a refrigerator immediately. ...
Any cans of Daily Serving: Blackberry, Plum, & Raspberry stored warm should be inspected for bulging and disposed of quickly to ensure they do not make a mess. Customers that would prefer to dispose of their remaining cans rather than take the risk of their cans bursting will be provided credit towards a future purchase upon request.
