  • Episode 189: Long Term Yeast Storage

    August 19th, 2024  |  25 mins 4 secs

    For smaller brewers, yeast management can be a challenging prospect. Many mid-size to small breweries attempt to make a wide range of beer styles that require a plethora of yeast strains. Due to production limitations, brewers are often forced to stretch yeast pitching windows or purchase brand new yeast pitches at a dramatically high cost. A study was performed to evaluate potential media that would allow for adequate dormancy and viability of harvested yeast slurries for long term re-pitching opportunity. Various media were added to decanted yeast slurry and viability was measured over determined time periods to track health of the stored yeast. Results indicate that monopotassium phosphate, standard distilled water, alkaline mineral water, and a solution with sunflower oil all provide varying degrees of health preservation of long storage periods up to one month. Minimal changes were observed with adequate dilutions and these results will be discussed.

  • Episode 174: WHAT IS BEER?

    July 22nd, 2024  |  1 hr 10 mins

    "The Inspiring History and Legacy of American Lager Beer" is envisioned to be a nine-volume series of books covering the history of the American lager brewing industry from the 1840s to the 1940s and the evolution of adjunct lager beer as America’s “national beverage.” The “surprising” aspect of this history is that it ever happened at all, given the half-century-long assault on the industry between the 1870s and 1910s to impose an “American Reinheitsgebot.” Unified in this objective were a plethora of the nation’s political, cultural, and agricultural institutions—all seeking to ban to use of rice and corn-based products in the brewing of American ales and lagers. Equally united in opposition to this effort were the brewers and brewing scientists of America. In battles that were passionate, highly public, and intense in nature, these brewing industry advocates successfully defended the right of American brewers to brew with the ingredients of their choice. It is a powerful legacy not only for America’s first revolution in beer (the adjunct lager brewing industry) but also for the nation’s second revolution in beer (the American craft brewing industry).
