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 2

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.

I want the MLB to be viable when I receive them. Without the ice packs and mailer, they probably would not survive.

Depends on area weather
I always pick this a insurance but it really depends on what the weather is doing and how long the insulated yeast sits in transit. I have had some arrive warm but always performed well when used in a yeast starter. I cannot say if the yeast would be as viable without the cool edge up front.

Yeast hotter than everything else in my order
I am disappointed I paid extra for the insulated mailer. When my Ingredients came the yeast and ice packs were about 20>f warmer than the inside of the box containing the rest of my order. At least it was the Omega Hot head yeast.....I will get it in a starter tonight and see if it is still viable.

Excellent Protection
These foam filled mailers provide excellent protection for life yeast cultures during shipping. The foam padding y insulates very well and prevents punctures or breakage. The cultures arrive cold and in perfect condition.

This is worth the extra you pay for insuring the stability of the yeast in shipping

Definitely worth it.
Shipped 2 yeast packs to NC and they were both still cold upon arrival.

worth the price
In warmer weather, this is worth the cost. No one can guarantee your yeast or culture will stay cool in transport. Mine arrives in a couple of days, thawed out but still cool enough to protect. Recommend.

It works
This mailer will keep your MLB at a proper temperature for 2 days at least in the mail. Works well, no problems.
