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 6
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.

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.

If I order 2 liquid yeast packets. Do I need 2 Ice & Insulated Mailers ?
Nicholas Michalko on Jan 24, 2019
BEST ANSWER: Hi Nicholas - On the provided item product page, in the description, there is a small table referring to our yeast and how many ice packs you would need for each brand of yeast.

Great Ice
Possibly the finest ice ever. It was probably quite cold while it was frozen.

Cool Pack Fail
One of the cool packs ruptured spilling contents onto the order. Fortunately, the material was packed in plastic and not damaged.
I was disappointed that with the extra cost for the cool pack the order was packed in a soft-side envelope that was easily crushed.

Terrible packing
More like a heating pad. Terrible packaging. BOTH shipments yeast was warm. Will NOT order again.

Not worth the $5...
It cost me to spend $20+ in liquid yeast. Yeast came to me hot. Added to a flask and starter and hopefully will see it propogate, but I'm afraid MoreBeer sent me hot dead bugs...

Response from MoreFlavor
We are very sorry to hear about your yeast and the trouble you had. We try to do everything we can to ship yeast, safely but the summer time is especially hard on the little ones. We also are always happy to recommend shopping at your LHBS for temperature and time sensitive ingredients if you're lucky enough to have one close by. Hope you were able to salvage your brewday. Cheers!

Never really makes it to my shop before its at room temp. I am in Florida so that might have something to do with it.

Won't protect for a Week in Summer Shipping
I'll caveat this writeup is in reference to shipping yeast during the Summer/Warm (hot) months...

This is just not sufficiently insulating to maintain yeast viability for more than overnight, with ice packs during summer months..

My order from MoreBeer! was submitted on Monday, and during selection, it showed availability in PA (I live in MD). But when the order went in, it was to be shipped Tuesday from CA. It was in transit almost a full week (received the following Wednesday, on time as expected), but I took it's temp, and it was at 80 degrees. Since the new WL packaging, I have had viability issues with WL yeasts, so this added to that challenge. However, Molly was SUPER HELPFUL when I called, and she had a duplicate order shipped out for overnight delivery! Her service is 5-Star!
