Includes 2 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 2 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 10
Imperial Yeast 3
Wyeast 3
GigaYeast 3
Omega 3

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.

Insulated mailer.
I did not use shipping that required a premium payment, just USPS. While the shipment arrived in good shape, the 'ice pack' was liquid at that point, but given the excellent packaging, the Yeast was cold to the touch. It was certainly worth the $4 for peace of mind.

If you are purchasing liquid yeast, this is a must. I have only used liquid yeast a few times. The first time I used liquid yeast, I didn’t have it shipped in an ice pack and their was very little activity. This time, after being shipped in an ice pack, the yeast performed much better.

FedEx bad, ice pack good
FedEx was late (as usual), the ice packs and yeast were still cool to the touch. Please stop using FedEx.

Added the ice pack with the insulated envelope hoping that the yeast would make the trip. It did. Yeast started like normal.

Helped, but is not great for summer months
The ice was completely melted (if they were even frozen) before receiving them. I was worried that the heat had killed my yeast, but they seemed to have survived. I would recommend going with a larger package with more ice packs if you ship any more than 1 package of liquid yeast.

Failed miserably!!!
I ordered the yeast with the cooled pouches. unfortunately they did nothing to keep the yeast cool/cold. Not impressed!!! If it's going to take 4 days to ship something, then only offerings that keep the yeast cold should be used!!!

it was a good try buy Florida heat won
It was well packed but even with the insulation and cold pack the yeast arrived hot. I am not complaining I knew with 95+ degrees days it was a risk. I have bought the same yeast from this place with great results before.

Need a different solution
Yeast is warm on receipt - even with two ice packs. The yeast started fine, but was likely stressed.
