This weekend, members of American Solera’s Society will be able to pick up an imperial stout aged in some very unique barrels.

Our Queen is an imperial stout aged in three different types of barrels before being blended together: an orange bitters barrel, a vanilla extract barrel and bourbon barrels. The new stout is an exclusive release for members of the Tulsa, Okla.-based brewery’s American Solera Society club, which debuted in 2016.

According to American Solera, Our Queen will be packaged in 500ml bottles and will be released on Saturday at the brewery, with each member being allocated four bottles. There will also be an extra 200 bottles of the imperial stout that will be sold for $20 each exclusively to members, with each member limited to one extra bottle.
