How We Handle and Ship Yeast

At SoCal Brewing Supply, we store all liquid yeast under optimal refrigerated conditions with 24-hour temperature monitoring to preserve freshness and viability. For best results when ordering online, we recommend adding an ice pack to your order.

Note: Ice packs may arrive melted, which is normal. Their purpose is to reduce temperature shock during shipping and protect yeast over short transit times.
