PLEASE NOTE! We do not ship liquid yeast. Yeasts are available online for IN STORE PICK UP ONLY. We order Imperial frequently, if this strain is out of stock, it will be placed on back order. Backorders are generally filled within 2 weeks. Placing a backorder on a strain ensures that when yeast are ordered you will be receiving the FRESHEST PACK not one that has been sitting around a shop for several months.
