The Bruery is commemorating another day of the week with a new bottled release, but you will have to be a member of the brewery’s membership program to get it.

According to Joel Kennedy, marketing manager at The Bruery, Sundae Sunday is a 17.2 percent ABV imperial stout aged in both bourbon and wine barrels “for about a year” with boysenberries and vanilla before being packaged in 750ml bottles.

The stout uses the brewery’s Black Tuesday imperial stout as its base, a beer that was first released in 2009.

In an email, Kennedy told Tenemu that Sundae Sunday will be an exclusive release packaged in 750ml bottles for its Hoarders Society membership programs and is scheduled to be released on June 4.
