These results are promising and stay tuned for some results from Escarpment Labs testing the impact of pH buffers and nutrients on yeast storage between batches. This study showed that a pH buffer (potassium phosphate) and sunflower oil can help improve yeast viability during storage between batches. If the viability is below 80%, we suggest using the yeast within 1 week of cropping.Ī great study titled "Long Term Yeast Storage: Novel Approaches" was shared at the MBAA conference in 2019 by Matt Couch at Lazarus Brewing. Note 2: Storage time is HIGHLY dependent on the viability of the yeast coming out of your fermentation. Note 1: If you are able to perform a propagation/“vitality starter” step prior to pitching, you can often extend the viable shelf life of your stored yeast up to several months. Increase pitch rate or make a starter if over 2 weeks.Ĭheck for presence of yeast cross contamination using a microscope before reusing. In general, we recommend maximum storage times of yeasts based on the following table: There is not much good information or data out there on how long brewery yeast will last between batches, especially at craft beer scale and with craft beer strains such as ale yeasts. How long can I store my yeast in a brink between batches of beer? If you have any concerns about the health of a repitch however, we always suggest going back to a fresh yeast pouch.
Note for homebrewers: you have a lot more flexibility here, if your stored yeast is more than 1 month old we recommend building up a stir plate starter and your yeast should be OK to use for several generations.
Our simple answer is: for most yeast strains, plan to reuse it within 3 weeks, although some strains can last longer between repitches. Since it is more cost effective to repitch liquid yeast, we thought it would be helpful to put together some resources and share some research we did on yeast storage time between batches of beer! Last year, Lazarus House Emergency Shelter and Center for Transitional Living Programs provided care for 137 individuals, 11,961, nights of shelter, and 35,000 nourishing meals to people in need in the community.One of the biggest challenges and mysteries that brewers using liquid yeast face is how long yeast can be stored in between batches without risk of poor fermentations or off-flavours. Lazarus House helps people in need find the shelter, food, and other support services they need to get back on their feet - open 24 hours a day, every day of the year. One dollar from every sale from the STC Six Collaborative Beer and the limited-edition glassware will go toward Lazarus House.
This is the perfect beer for the warm weather and is best enjoyed sitting outside on a patio soaking up the sunlight. This light-bodied beer has the hop profile of grapefruit, floral aromas, and a hint of lemon zest all coming from the Centennial and Lemondrop hops. The 2023 STC Six has come together to craft a Summer Pale Ale. The breweries invite everyone to help celebrate the launch with the first opportunity to taste the new beer on Wednesday, June 14, starting at 5 p.m.
