BBXMAD1 – The Mad Fermentationist Saison Blend

Availability: Limited

Source: A unique blend of cultures curated by The Mad Fermentationist, Michael Tonsmeire

Bootleg Biology is proud to announce The First Official Mad Fermentationist Culture!

Fine tuned over two years, this blend morphed over time to become an elegant powerhouse of classic Saison spice, stone-fruit Brett, lactic tartness and a dry but well-rounded body. The final master blend consists of Saison yeast, wild Saccharomyces, rare Brettanomyces and an opportunistic Lactobacillus culture.

At temperatures as low as 68F (20C) The Mad Fermentationist Saison Blend exhibits a relatively clean primary fermentation profile and high attenuation. Traditional saison temperatures (around 80F/27C) bring out citrus and elevated phenols (pepper and clove). The Brett character shifts depending on wort composition, as maltier beers emphasize cherry and stone fruit qualities.

This blend integrates beautifully with fruity and tropical hops, with the unique Brett culture keeping hop aromatics crisp and bright for an extended time. For best results use a highly fermentable wort, dry hopping during the tail of active fermentation, and carbonating naturally.

    Perfectly versatile Saison Blend. How you brew determines what this blend does.
    More IBUs decreases the acid. Higher mash temps favors the Brett. Add sugar to increase the dry spice.
    A great blend that lets you experiment/refine your brewing techniques. All with different beers in the end.

    Used this yeast 3 times now, and love it. I do make a 2 liter starter for a 5 gallon batch (1.070 gravity), within 5 hours fermentation is going very well. First 2 times using it, the beer came out excellent. Lots of fruit notes (pear, peach, apricot) with a nice, light Brett backbone.

    This is a fantastic and very versatile blend. It makes great hoppy saisons, it makes great funky saisons and when pitched into unhopped wort it makes great sour beers in about 6 months. This blend does it all and gets extensive use in my brewery.

    Ordered 6 different strains. Brewed the Maltose Falcons “Saison Experimentale” recipe and split into 6 buckets. The Mad Fermentationist Saison Blend was good 6 weeks after bottling, but was great at 12 weeks when the brett funk developed and gave it great balance. Not very sour yet, but again, well balanced. Definitely will used this one a lot.

    Great High attenuation and nice tropical brett after 3 months of conditioning. I was hoping for something close to WLP670 Farmhouse but different and this does a great job at that. Makes a great American Farmhouse or funky Saison
