Species: Lactobacillus brevis

Profile: Unlike most lactic acid bacteria used in brewing, Lactobacillus brevis will tolerate higher levels of IBUs in wort. 5223-PC will produce alcohol along with lactic acid during fermentation. This strain is excellent for remixing the profile in a Lambic-style or Flanders Red Ale, or for kettle souring wort for a balanced Berliner Weisse.

Metric Temperature Range: 15-35 °C

Species: Saccharomyces cerevisiae var. diastaticus & Brettanomyces blend

Profile: A blend of two saison strains and Brettanomyces creates a dry and complex ale. Classic earthy and spicy farmhouse character meets tropical and stone fruit esters. Aging brings elevated Brett flavor. Expect high attenuation with this blend.

Metric Temperature Range: 18-26 °C

Notes: This blend contains Wyeast yeast strains that have been classified as Saccharomyces cerevisiae var. diastaticus using rapid PCR analysis. These strains carry the STA1 gene, which is the “signature” gene of Saccharomyces cerevisiae var. diastaticus and will be found in all diastaticus strains.

Species: Saccharomyces cerevisiae

Profile: This strain is ideally suited to the production of West Coast-style American craft beers, especially pale, IPA, red, and specialties. Thorough attenuation, temperature tolerance, and good flocculation make this an easy strain to work with. Flavor is balanced neutral with mild ester formation at warmer temperatures, allowing hops, character malts, and flavorings to show through.

Metric Temperature Range: 17-23 °C
