From summer sours to winter warmers, we aim to capture the feel and flavor of each season in our unique Private Collection releases. These exclusive strains are either selected from our extensive archive or a little something experimental we’ve been working on, but they are always a limited release. Explore this season’s strains below.
Limited Release from July through September 2021.
Species: Brettanomyces claussenii
Profile: This wild yeast produces a mild “Brett” character with overtones of tropical fruit and pineapple. Typically used in conjunction with other yeast and lactic acid bacteria, it ferments best in wort with a reduced pH after primary fermentation has begun. It may form a pellicle in bottles or casks.
Metric Temperature Range: 15-24 °C
Species: Saccharomyces cerevisiae
Profile: Isolated from a small Belgian brewery, this strain produces beers with moderate esters and minimal phenolics. Apple, bubblegum and plum-like aromas blend nicely with malt and hops. This strain will finish dry with a hint of tartness.
Metric Temperature Range: 18-23 °C
Species: Saccharomyces cerevisiae
Profile: A widely-used strain in the production of Witbier and Grand Cru. This yeast will produce spicy phenolics which are balanced nicely by a complex ester profile. The subtle fruit character and dry tart finish will complement wheat malt, orange peel and spice additions typical of Wits.
Metric Temperature Range: 17-24 °C
