About

A grouping for the non-commercial wild yeast and bacteria cultures used across spontaneous and mixed-fermentation sour ales, where the exact microbes differ from batch to batch (captured cultures, dregs, blends and barrel slurries). Because each pitch is different there are no fixed specs; the individual brew notes record the culture origin and result, and the stats below reflect what these mixed ferments have actually achieved across your batches.

Recipe pairing

Grains
Pilsner and wheat-forward bills for lambic and saison-leaning sours
Hops
Aged or low hopping so the culture leads
Adjuncts
Fruit and barrel character are common; long aging develops complexity
Suited to
Wild Specialty Beer, Lambic, Saison, Farmhouse Ale

Brewing tips

  • Treat each batch on its own terms; the culture and result vary, so the per-brew notes are the real reference.
  • Expect long, slow fermentation and souring rather than a predictable primary.
