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.

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.

Just the thing for mail delivery
My 2 packs of WLP802 arrived in two days and the yeast was still cool when I opened the package. It is large enough for more than two packs of WLP.

Sides exposed
If you order liquid yeast with the packaging, I suggest you don't do in the summer (which is what I did). It's just a sandwich of insulation with the sides offering nothing. The ice pack was completely melted when it got to me. Again, this was July or August when I ordered, but that's why I ordered the insulated pack.

Be Careful
If you find that your yeast(s) are shipping from a different address, as mine were, make sure it's only a 2-day delivery window. My delivery window was 5 days, but only revealed after payment...the yeast was probably impacted given my slow ferment, even with a starter. I re-learned an old lesson: buy fresh, local yeast.
