WHITE LABS YEAST
The success of your brewing with our ingredients is very important to us. Your yeast is guaranteed healthy and fresh from the date of delivery to the expiration date; it will still be highly viable for a period beyond the expiration with the use of a starter. We recommend always using a yeast starter prior to pitching to ensure healthy yeast growth and good fermentation. If you do not get significant yeast growth in the starter or active fermentation in the primary we will replace the vial of yeast at no charge (shipping included); we can replace the yeast but not a batch that fails to ferment properly.
