BB22204 – S. Arlingtonesis – Bootleg Biology HB Pitch

BB22204 – S. arlingtonesis

From Bootleg’s website:

Availability: Limited

Source: Isolated from wild yeast starter jar in Arlington, VA.

S. Arlingtonesis is Bootleg’s flagship Local Yeast Project strain. The very first culture added to our bank, and luckily, one of the most unique.

“This culture ferments extremely cleanly in the low 60’sF (Kolsch and Lager hybrids), and subtle fruity/citrus esters in the higher end of the Ale fermentation range (wheat-centric beers). May produce sulfur aromas during primary fermentation, but those will be eliminated within a couple weeks (allow longer aging if fermenting at lower temperatures). S. arlingtonesis is a higher attenuator than most ale strains, so adjustments made need to be made to grain bills or mash temperatures if a drier beer is not preferred.”
