Jester King Brewery is producing another SPON variant, and this one is being aged in very special barrels.

In an email, Jeffery Stuffings, owner of Jester King, told Tenemu that the Austin-based brewery put a fresh batch of wort from its coolship into Armagnac barrels, a type of brandy produced in the southwest portion of France. According to Stuffings, six 225L barrels were filled, and the beer is expected to age for between 18-24 months before being bottled.

SPON — Armagnac is the fourth SPON variant so far, after 2016 SPON — Raspberry & Cherry, 2016 SPON — Peach & Apricot and 2016 SPON — Flor were released in December 2016. In November 2016, Jester King debuted its first 100 percent spontaneously fermented beer named 2016 SPON — Méthode Gueuze, a blend of one-, two- and three-year-old 100 percent spontaneously fermented beer that was made using the same traditional method that produces authentic Belgian gueuze.

While the first three variants of SPON were packaged exclusively in 375ml bottles, Stuffings told Tenemu that there is a possibility that SPON — Armagnac will be sold in both 375ml and 750ml bottles when it is released.
