HAVE YOU SEEN OR USED OUR PUREPITCH NEXT GENERATION PACKAGES? 


Do you still have some questions about what is printed on the pouch and how much to use? If the recommendations confuse you a little bit, or you just want to dig into some of the science behind it, keep reading!
 

SAME SIZE, SAME CELL COUNT


Our PurePitch Next Generation’s modular size fits perfectly with the advancements we have made in precise and consistent cell concentrations. Each lot is cultured and harvested with specific specifications to ensure each pouch arrives with a consistent 2.15 billion cells/mL. Making all strains and lots you’re getting the same amount of cells in each and every pouch! 

Making it easy to pitch 1 pouch into 5 HL/BBL of standard wort, 2 pouches into 10 HL/BBL, and 3 pouches into 15 HL/BBL, all at the same consistent pitching rate of 7.5 million cells/mL.
 


 

ONE SIZE DOESN’T FIT ALL


Our easy recommendations work for most fermentations, but we recommend doubling your pitch rate when starting your fermentation below 61℉/16℃ OR at a higher gravity of 18P or higher. If your fermentation has both, we recommend tripling your pitch rate. These are due to some important factors explained below.
 

WHY PITCH MORE WITH COLDER FERMENTATION


The most important reason is that colder temperatures inhibit yeast activity to some extent, resulting in reduced or slower cell growth.
 

Slower cell growth can cause longer fermentation timelines, varying flavor profiles, and most commonly a stuck fermentation. To prevent this, we recommend pitching more yeast to ensure complete fermentation. This means increasing your pitch rate to 12+ million cells/mL versus the standard 7.5 million cells/mL.

WHY PITCH MORE WITH  HIGH GRAVITY BREWS


Higher gravity brews provide a higher stress environment for yeast cells. Not only is the wort viscous and challenging to reach adequate DO (dissolved oxygen) levels, but higher gravity fermentations also need the healthiest yeast possible to withstand the higher alcohol levels. To overcome this challenge, more yeast is required for a robust and reliable fermentation. 
 

FOOL-PROOF FERMENTATION


Still unsure how much to use?  We have you covered there too! Our online yeast calculator provides an easy way to find and customize your pitching rate. 

Input your batch size, pitching temperature, and starting gravity, and let the calculator give you the optimal pitching rate and the number of pouches needed.

PERFECT YOUR OWN PITCH RATE


Are you looking for a specific pitch rate? Do you want to under pitch for a kveik fermentation or pitch a lager fermentation at a higher rate such as 1.5 million cells/mL/°Plato? 
 



Our calculator also provides an advanced button where you can customize the pitch rate by moving the Pitching Slider to your perfect pitching rate, larger or smaller! 
 

With PurePitchNext Generation, we made it easier by giving you the customization to create your own fool-proof fermentation!
