WildBrew Philly Sour Brewing Yeast (2 Pack) - Lachancea spp. | CAPYBARA Distributors Inc.

Overview

WildBrew Philly Sour is the first yeast in CAPYBARA's WildBrew line, a Lachancea species discovered in nature and studied at the University of the Sciences in Philadelphia. In a single fermentation, it yields modest lactic acid alongside ethanol, delivering a refreshing acidity with stone-fruit character. This versatile yeast is designed for homebrewers who want to push creative boundaries while keeping a straightforward process.

Key performance traits

• High attenuation (roughly 74–82%), which can lead to a drier finish in many sour beer styles.
• High flocculation and reliable head retention for clearer pours and satisfying textures.
• Temperature range of 20–30°C (68–86°F) with an alcohol tolerance up to 9% ABV, giving you flexibility across environments.
• Hop resistance, making it a good match for hop-forward sour beers like Sour IPAs.
• Produces lactic acid in addition to ethanol within a single fermentation, enabling a distinct, drinkable acidity without blending cultures.

Ideal beer styles and uses

• Berliner Weisse and Gose — classic tart profiles with bright acidity.
• Lambic-style and American Wild Ales — fruit-forward complexity with a rustic edge.
• Sour IPA and other hopped sours — balance fruity hop aroma with tartness.

What’s included and how to use

• Includes 2 x 11 g sachets in a 2-pack, ready to pitch into your wort.
• Pitching guidelines align with wort gravity: 50–100 g/hL for <14°P, 100–150 g/hL for >14°P.
• Best results within 20–30°C (68–86°F) to match its target range.
• Expect a clean fermentation with the potential for a moderate aroma of stone fruit, depending on your recipe.
