24-Hour Yeast Shipping Protection | Insulated Mailer + 8 oz Ice Pack

24-Hour Yeast Shipping Protection for Liquid Yeast Orders

This protection option is built for shorter yeast shipments where the goal is to reduce heat exposure, buffer temperature swings, and give your liquid yeast a better chance of arriving in healthy condition. It uses a lightweight Cool Shield bubble mailer paired with an 8 oz cold pack, making it the right starting point for many overnight or true next-day routes.

At SoCal Brewing Supply, we keep liquid yeast in temperature-monitored refrigeration 24 hours a day before it ever leaves our facility. That part is under our control. Carrier handling, routing delays, hot trucks, weekend holds, and extended transit are not. That is why we strongly recommend choosing the right protection level and using expedited shipping whenever liquid yeast health matters to you.

What this option includes

• One lightweight insulated bubble mailer sized for yeast shipping
• One 8 oz cold pack included in the base price
• Optional extra ice packs for customers who want more protection

Best use case

• Best for 24-hour protection expectations
• Best paired with next-day or truly short transit routes
• Useful for customers who want a lighter, lower-cost layer of yeast protection

What it does and does not do

This package helps protect liquid yeast from temperature spikes during normal short transit. It does not guarantee arrival temperature, yeast viability, or perfect carrier performance. If a package is delayed, left in a hot truck, rerouted, or held over a weekend, that is outside our control. Melted ice packs on arrival are normal and do not automatically mean the protection failed. The cold pack's job is to slow warming and reduce the severity of temperature abuse, not to keep yeast refrigerator-cold indefinitely.

How to choose the right amount of ice

Your base purchase includes one 8 oz cold pack. You can add extra packs if you are shipping into hotter weather, a warmer region, or a route that feels riskier than normal. Customers are responsible for selecting the level of protection they want for their shipment. If you are worried about heat, longer routing, or uncertain delivery timing, it is usually smarter to add protection and pay for faster shipping now than to gamble with liquid yeast later.

Important shipping guidance

• Liquid yeast orders are best placed Sunday through Wednesday, depending on expected transit time
• This helps reduce the chance of shipments sitting in carrier systems over a weekend
• Flat-rate ground shipping has no transit-time guarantee and may take longer than estimated
• Dry yeast is much less risky to ship than liquid yeast
