Our Commitment to Yeast Health

At SoCal Brewing Supply, we take yeast storage and viability very seriously. We ensure yeast is always stored under optimal conditions, with 24-hour monitoring of refrigerator temperatures to prevent spikes that could negatively impact yeast health.

For liquid yeast orders, we recommend shipping with an ice pack and insulated envelope to ensure your yeast arrives in top condition. It’s normal for ice packs to melt during transit; their purpose is to protect the yeast from extreme temperatures caused by external weather conditions.
