Helps extend the time that the yeast stays cool in transit. Cool temperatures help keep the viability of the yeast higher which in turns leads to faster fermentation start times and better beer. The Insulated shipper helps the ice last much longer, however neither option will ensure your yeast stays cool the entire trip.
The Insulated Shipper option can hold 10 White Labs packages, 3 Wyeast packages, 3 GigaYeast packages, 3 Omega Yeast packages, or 3 Imperial Yeast packages. Check out ICE1 for more information.
The Large Insulated Shipper option can hold 30 White Labs packages, 12 Wyeast packages, 12 GigaYeast packages, 6 Omega Yeast packages, or 5 Imperial Yeast packages. Check out ICE2 for more information.
NOTE: We highly recommend ordering DRY YEAST during hotter months as your liquid yeast may get warm during the delivery period, even with multiple ice packs included. The insulated mailer offers better protection, but is still not guaranteed.
