Includes 4 ice packs and an insulated mailer to help keep your liquid yeast cold during transit.  The Insulated Mailer option is a great way to extend the length of time your ice remains cool!  These special envelopes contain self expanding foam, which creates a form-fitting container that protects and insulates liquid yeast.  This upgrade includes the Insulating Envelope and 4 Ice Packs.

This option fits a number of yeast vials, pouches, or cans, and is made from thick foam insulation.  Because different yeast take up different space, each producer will fit a different quantity in this mailer.  See the chart below for what quantity of what yeast will fit inside.

Yeast Producer / Brand Quantity that will fit in Insulated Mailer
White Labs 22
GigaYeast 12
Wyeast 12
Imperial Yeast 5
Omega 6

If you aren't ordering this many yeast and want a smaller insulated mailer, check out our ICE1.

To purchase, simply add however many Insulated Mailers will be needed to contain however many yeast are in your cart.

Please Note!  Any additional yeast will be shipped outside of the mailer.  This option includes ice, and no additional ice needs to be purchased.

Please note - Liquid yeast will not arrive cold even when shipped with ice packs. Ice packs and insulated mailing options are designed to keep the yeast colder for longer during shipment, but they will not ensure that your yeast arrives cold. We will not replace liquid yeast that arrives warm. During warmer months we strongly recommend you choose dry yeast.

Arrived completely melted, 75F
Not satisfied when purchasing the largest ice pack offered and the yeast arrived at 75F. I understand it is warmer weather, but I live in northern CO and day temps were only in the 80s. It’s more economical to drive 30 miles to a home brew supply store to get my yeast than to pay for 1 or 2 day shipping and the ice packs.

If you have to order liquid yeast in the summer it's a must
Awesome. Usually i don't order liquid yeast in summer. Went with express shipping and the yeast was still cold when It arrived 2 days later, I mean cold not cool. The shipper has 1" thick foam insulation top and bottom and I got it with 4 ice packs.

Great in theory, and better than nothing
The issue is that the package is not fully insulated. It's got an end that is just a plastic flap that has the adhesive to close the package. Thermally speaking, there's no seal on that end.

Ultimately, this would be better than nothing at all, but shipping in summer, after 3 attempts each time, I received expanded yeast packs and ice packs that were physically warm to the touch (meaning they were all over 100F) There should be better sealing shippers for temperature sensitive items that actually seals the contents properly.

BTW: This is a review of the product itself. Customer service was amazing and really worked to make things right. However, trying to order seasonal yeasts failed due to the design of this insulated sealer.

Do a good job of insulating yeast
I have used these insulators for every liquid yeast I have bought. Only once during the heat of summer (August) did they not work. I highly recommend that you use these for any liquid yeast you buy. Do not expect them to work in anything over 80 degrees for more then one day.
