works great

Review by jeff on 1/8/2016

Shipping liquid yeast cross country can be a problem especially in hotter weather as the exposure to heat can kill much of the yeast in transit. This yeast warranty box is a great idea as the Styrofoam lining helps insure your yeast will arrive cool and healthy. Brewing 18-20 gallon batches as I do is too expensive to risk a bad fermentation from a weak culture from yeast kill off during transit. I will never have liquid yeast shipped again without one of these warranty boxes. Thanks Williams for your innovation & great service! Worth every penny.!

This has always proven to work even during the hot Summer months and my coast to coast shipment. Never buy without it.

Great option - fantastic to preserve the yeast and warranty.

I have ordered many times and on a couple the yeast did not make it. I have ordered yeast using the insulated box and so far no issues. Nice to have everything right when I brew and not have to hold the primary while replacement yeast is shipped.

first time using the yeast box, used to live in california and receive yeast in 1 day, took 2 days to receive the yeast box which was shipped seperately from the rest of my order. yeast was still cool to the touch upon opening

Must have for the summer months

Review by Jeffrey on 10/2/2014

It usually takes about five or six days for my order to reach me all the way out in NC. I have never had a bad yeast packet when I get the warranty box with the ice packets, even when I order in the hot months of June and July. It's definitely worth the $7. You probably won't need it if you're ordering in December or January. But in the warmer months, it's definitely a must buy.
