Ice Pack & Insulated Popup Pouch Mailer

Liquid yeast is alive, and it needs to stay that way during shipping. This ice pack and insulated popup pouch combo gives your order real cold-chain protection — not just a thin foil layer. The popup pouch holds up to four packs of liquid yeast and uses 1 3/8" thick self-expanding foam that conforms around your yeast pack, keeping your yeast colder for 48 hours longer than standard ice and bubble mailers.

What's Included

• Insulated popup pouch — holds up to four packs of liquid yeast; self-expanding foam insulation, no cardboard box needed
• Reusable ice packs — provide hours of cooling in transit

If you're ordering liquid yeast, this is the right call — especially in warm weather or for longer transit times.

Please note: This ice pack and popup pouch is designed to keep your yeast colder for longer than our standard ice and bubble mailer (up to 48 hours long), but we cannot guarantee your yeast will arrive cold. We are unable to replace liquid yeast that arrives warm. During the warmer months, we strongly recommend ordering dry yeast instead.
