After making the same beer for 10 years, Allagash Brewing Co. is changing things up a bit.

While Interlude will remain the same 10 percent ABV Belgian-style ale that is aged in red wine barrels, the packaging is changing from the 750ml bottles that it has been sold in since its inception to 1.5l magnums in order to commemorate the 10-year anniversary for the beer.

“Two yeast strains were used to create this Belgian style ale,” reads the label. “The first, a Saison yeast, establishes the flavor foundations of a classic Belgian-style ale. The second, a house strain of Brettanomyces yeast, contributes a myriad of flavors including pear, apricot, graham cracker, and bread crust. A portion of the Interlude is aged in red wine barrels, which imparts a distinctive vinous, plum character and a drying, almost tannic finish.”

According to a label submitted to the Alcohol and Tobacco Tax and Trade Bureau (TTB), the 10th anniversary release is limited to just 1,500 bottles.

An email sent to the brewery for additional details was not returned.
