A classic Yeti variant is being bottled for the first time.

According to a label filed with the Alcohol and Tobacco Tax and Trade Bureau (TTB), Great Divide Brewing Co. will be releasing Vanilla Oak Aged Yeti, a 9.5 percent ABV imperial stout brewed with vanilla and aged in both French and American oak barrels. The stout uses the Denver-based brewery’s Yeti imperial stout (9.5 percent ABV) as its base, a beer that was originally released in 2003.

Oak-Aged Vanilla Yeti will join three other Yeti variants being released this year:

  • Chocolate Oak-Aged Yeti — 22-ounce bottles available from January-April
  • Oak-Aged Vanilla Yeti — 22-ounce bottles available from May-August
  • Chai Yeti — 22-ounce bottles available from September-December
  • Barrel-Aged Yeti 2018 — 22-ounce bottles available from November-December

According to Great Divide’s 2018 release calendar, Vanilla Oak Aged Yeti will be packaged 22-ounce bottles and is scheduled to be shipped to retailers in May.
