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 5
GigaYeast 3
Wyeast 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.

Did not remain cool. Was thawed out completely in delivery.
This was completely thawed out when I got it and I question the yeast. It was not more than 80 degrees during shipping.

Hello Rodney - We apologize your yeast did not arrive at an ideal temperature. This product is intended to prolong the viability of yeast, and is not foolproof.

Yeast arrived cool in warm weather.
It only takes 2 days to arrive but my 4 packages of wyeast were still cool when they arrived. The yeast took off very well when I used it.

Let there be cold!
You want to use live yeast? And you are ordering during warm months? Then you better protect your yeast and therefore your investment by keeping the yeast as cool as the underside of the pillow whilst in transit.

It worked but...
This did not let my yeast get above 78 degrees however I would not recommend doing this if its particularly hot and the package is going to have to sit outside for very long. My yeast is working great but I feel like I cut it pretty close.

Didn’t work for me
Useless for me as my Imperial Yeast arrived borderline hot. It’s probably useless as well.

A good idea that needs to be cold longer so when it's delivered it doesn't warm up too quickly.
A good idea but when it arrived the ice was at outside temp and the yeast was also warm. Thankfully it wasn't too warm and is fermenting fine.

It didn’t last very long. By the time I got it it wasn’t really cold anymore.

Kept yeast cold
I was impressed buy the cold packs and the insulation. The cold packs were still cold when the package came. I think they could stay cool another day in Spring weather. I will order yeast again and this package with it.
