Yorkshire Square Ale Yeast PurePitch Next Gen WLP037

The PurePitch^® Next Generation is an evolution of White Labs' PurePitch - the most superior and consistent yeast on the market - has been made better with new packaging powered by FlexCell^® technology for ease of use and a pitch rate resulting in a foolproof fermentation every time. The new packaging features a modular pouch with a cap and a consistent cell concentration intended to pitch at 7.5 million cells/mL per 5 gallons. The new process has also increased the viability and improved the shelf life of the yeast now lasting 4-6 months. Meaning that now you get more yeast and a foolproof fermentation with out a starter since you are starting out with 2x the pitch rate than before.


Yorkshire Square Ale Yeast WLP037 is a yeast that will produce a beer that is malty and well balanced. You should expect toasty flavors with malt driven esters.

It is highly flocculent and a good choice for English-Style Pale Ales, Brown Ales and Milds.
