White Labs Yeast & Fermentation

In this episode we're doing a CRAZY yeast experiment - a smash ale, 4 way split batch by separating a single batch of wort into 4 different fermenters and pitching 4 different yeasts. We then taste them side by side to see how much of an impact just the yeast has on the finished beer. The beer we make is fairly simple, just Maris Otter and Zula hops (a new hop!). Our assistant brewer in this video is Jo Doyle, the Education & Engagement Curator at White Labs. She's a BJCP Certified Beer Judge and Certified Cicerone, so she's a real pro when it comes to beer. If you're a fan of White Labs, yeast, craft beer, or homebrewing this video is for you.

We turned to packaging solutions experts at Landsberg Orora to bring you an improved shipping package that outperforms our previous boxes AND is good for the planet.

PurePitch Next Generation packaging is not just here to look good! ????The beautiful sleek film serves a purpose: keeping your yeast viable as long as possible!????

Is PurePitch Next Generation the best thing since sliced bread? ???? That’s up to you, but we think these pouches are pretty special! Like sliced bread, you know exactly what you’re getting with PurePitch Next Generation Homebrew. Consistent pitch rate = foolproof fermentation.

Cell counting doesn’t need to be intimidating! Make it easy with our new series on some of our favorite cell counting tips and tricks! ???? ????Leave a comment below if you have a great tip to share or if you have cell counting questions and tune in for our next installment!

????Started from the bottom, and we’re counting. Make focusing easy by starting with the slide deck at the bottom and the lowest magnification. That means the only way to go is up! At 10x, a 5x5 grid should appear, at 40x, individual countable squares and cells will be counted. Stay tuned for next installment of cell counting tips!

A Law of averages. Cell counting is all about being reproducible and accurate. Save time while still maintaining an accurate count. Perform counts on only 5 of the 25 squares! You’ll multiply by 5 later on to get the 25 squares????

A Law of averages. Cell counting is all about being reproducible and accurate. Save time while still maintaining an accurate count. Choose 2 sides of the border and keep them consistent on all 5 counting squares!

Don’t be so blue????! We have another round of quick tips to make cell counting easier! Check out whitelabs.com under product & services and lab services; we have a bunch of lab supplies ready to be ordered and used! Be on the lookout for more tips and tricks????

When to count and when not to count is the question????? Good SOPs with pictures can help standardize dye color and cell size for staff to differentiate live/dead cells and mother/daughter cell. As long as the team does it the same way, it will lead to more consistent results!

Having trouble counting flocculant strains? Use EDTA at a concentration of 0.01% or 0.5M as a deflocculating diluent to help break up those clumps. Be on the lookout for more cell counting tips ????

Whitelabs.com offers a plethora of lab supplies to start counting or start your own microbiological program. Don’t want to do your own testing just yet, we also offer 3rd party QA/QC analysis through our analytical lab.

I’m not dead yet ???? Why not save a batch of beer by calculating the viability. Viability can help determine if it’s alive enough to be repitched or if it’s time for new yeast. Also keep an eye on the fermentation kinetics as that can also be an indicator for poor performances from yeast generations.

Slurry calculations don’t need to be blurry ????. We’re here to help you figure out how much yeast was counted for a yeast slurry concentration. Just in time for repitching! Watch til the end to see our cheat sheet on the math with a 1:200 dilution ➕➖➗✖️⁉️

????How many yeast cells are you adding to your brew? Is it total number of cells, per volume size of tank, or factoring in both Starting Gravity and Volume? ????Pitch with our PurePitch Next Generation recommendations and stay tuned to learn about other parameters to make some happy yeast!

Have you ever eaten way too much and feel totally bloated? ????Or had way too little food and needed another meal right after? That’s just like yeasts role when introduced to different starting gravities! ????Keep yeast happy by providing enough cells adequate for each brew. This will help control their growth curves as well as reduce some risk of unwanted flavors or even worse stuck fermentations. Happy brewing ????

Fermenting on a schedule is all about balance ⚖️ ⬆️Higher temperatures will lead to faster ferments but will also increase esters, fusel alcohols, and other maybe unwanted flavors ⬇️Lower temperatures help reduce some of these flavors and aromas while slowing down cell growth and fermentation timelines We typically recommend starting most ferments at 68F(20C) for ales and 50F(10C) for lagers as a starting point. Just like humans, do you function better at warmer temperatures☀️ or colder❄️? But have you tried a pitching a saison yeast and letting it free rise? How about a Kveik yeast and fermenting hot as it evolved to produce a “clean” beer at higher temps!

❌ DO in a packaged beer. ✅ DO at the beginning of fermentation. Dissolved Oxygen helps allow yeast cells to be hardy and withstand environmental stresses. Adequate DO levels help lead to improved cell growth, improved attenuation, improved fermentation rates as it minimizes cell stress and helps control flavor compounds!

????Improved Yeast Health for Better Fermentations! Zinc Buddy™ comes as a????‍???? Sterilized, Acidfied, and Ready to Use zinc concentration that stimulates protein synthesis and yeast growth. Resulting in the improvement of yeast viability and overall yeast health. Just mix well before using, spray with sanitizer and carefully pour desired volume of Zinc Buddy™ into the fermenter before or during knockout for adequate mixing with the wort. Learn more at whitelabs.com

Train your yeast like a proper workout regime ????️‍♂️ Start lower generations at lower gravities, IBU, and color and work your way up! ????Track everywhere your yeast goes from what generation, fermenter, previous beers, viability/previous fermentation timeline and how long it was stored! It’s always good to have a beer in the portfolio that’ll be the “yeast prop” beer, something quick and easy for the yeast with a great yield for beers to come!

????What Fermentation parameters do you track? Gravity and pH, how’s the yeast look and smell, is the lag time longer?

⏰Timing counts! When are you adding your brewing enzymes and nutrients? For proper mixing and homogenization, adding enzymes during knockout with wort being pumped in helps provide adequate physical force to help mix and increase surface area for enzymes to do their thing!

How many generations do you get out of your yeast? ????Check out @craftbeerbrew podcast EP348 for Keys to Successful Beer Fermentations to optimize your yeast generations!

Faster ferments and better attenuation! With better efficiency, Zinc Buddy can help save money on overall ingredients costs ???? and lessen fermentation tank time ⏰! Which means more beer sooner ???? Check out the benefits of Zinc Buddy at whitelabs.com and try it in your next brew day????
