<aside> 🤖 About Optimus Primary:

Brett primary fermentations can be beautiful, but are often unreliable and frustrating. Optimus Primary is a new approach for Brett-forward, quicker-turnaround beers.

We devised a unique blend of Saccharomyces and Brettanomyces that produces the prominent pineapple esters of our Brett D, but with the reliable turnaround time of ale yeast. With Optimus Primary, you can get Brett-primary character in half as much time.

We supply Optimus Primary ready to pitch at the correct ratio for your wort. Please note that this ratio is not stable and results may vary when repitching. However we will supply the components to Pro brewers to save some of the Brett and prop up for repitching if desired.

Brewery testimonial:

Optimus Primary was test-driven by Oast House Brewery to make their Full Orchard Farmhouse IPA. Here’s what Mike Pentesco at Oast House had to say:

We have been pretty happy with the blend so far. Definitely getting the nice tropical fruit and pineapple that I am familiar with from our previous Brett D ferments as well as that moderate phenolic funk.

Ferment went from 13.8ºP to 4ºP in 3 days, by day 10 it was at 1.4ºP and stable. The plan is for total turnaround time to = 3 weeks, a savings of 2 weeks.

FAQ:

Can I repitch Optimus Primary? We supply Optimus Primary ready to pitch at the correct ratio for your wort. Please note that this ratio is not stable and results upon repitching may vary.

For pro brewers, we supply the components separately so you can prop up some of the Brett to hit the correct ratio when repitching.

What strains are in Optimus Primary? Optimus Primary is a blend of Cali Ale and Brett D. It sounds a bit weird pairing such a neutral Sacc with Brett, but it works really well! We noticed this combination performed surprisingly well during research conducted at the University of Guelph. The Cali is nice and attenuative to boot, resulting in less risk of overcarbonation.

But my Brett primaries work great! That's awesome to hear! Unfortunately, we have found these ferments to be unreliable in many breweries so we created Optimus Primary as another option.

Why is Brett so slow at primary fermentation? Put simply, Brett has not been domesticated for beer primary fermentation like Saccharomyces. This means it sometimes struggles in this environment, especially switching from an oxygen-rich environment to an oxygen-deficient environment. Brett's lack of domestication means it often lags for a long time or doesn't take off when it is used in beer primary fermentation.
