Please note the wyeast yeasts are sent out without any cooling products, we been selling liquid yeasts for years and have very little trouble. Just try to avoid ordering on a Friday as they could be sat in the Parcel Force depot over the weekend. When using any liquid yeasts good idea to have a dried yeast as a backup JUST IN CASE.
Elevate the quality of your homebrews with Wyeast Premium Liquid Yeast.
With Wyeast Activator Smack-Packs™ that double as a yeast viability test and with proven quality control – allowing your craft brewing skills to ascend to new heights.
For 35 years, the Wyeast Activator™ is the only product that “proofs” the yeast and shortens lag time when it hits your wort. Activator™ packages include an internal packet which, when smacked, releases its contents into the yeast slurry and revitalizes the cells. The available sugars and nutrients initiate the culture’s metabolism which in turn generates CO₂ and causes swelling of the package, serving as a viability and vitality test as well. Although beneficial, cultures do not need to be activated prior to inoculation.
