FREE ICE PACK available with your yeast purchase.

Please request one in the ORDER NOTES section at checkout.

After a conversation with Lance Shaner, Owner of Omega yeast, the following was added to the FAQ section of their website:

My pack of yeast is swollen. Is the yeast still good to use?

Swelling of the pack is not an indication of a problem with the yeast. It is the result of slow fermentation of residual fermentables during storage. The yeast is still perfectly fine to use (assuming it is within date and has been stored properly)
