Allagash Brewing Co. is brewing up a new beer, this time using various parts of blood oranges.

Dubbed Invisible Orange, the 9 percent ABV Belgian-style porter is brewed with two-row malt, coffee and chocolate malts as well as both blood orange pulp and zest before being hated in French oak wine barrels for 18 months.

“After fermenting with a Belgian Abbey yeast, it was transferred into barrels and underwent an aging period in barrels with Lactobacillus and Pediococcus,” reads the label. “Before packaging, a small amount of fresh blood orange juice was added.”

According to filings with the Alcohol and Tobacco Tax and Trade Bureau (TTB), the new bottle-conditioned beer will be packaged in 375ml bottles. An email sent to the brewery for additional details was not returned.
