Safale US-05 American Ale Yeast - Fermentis

Safale US-05 American Ale Yeast - Fermentis

Please select from the following option(s) to see pricing and availability.

Formally US-56, US-05 is a strain of yeast that creates that classic American profile of clean malt, crisp taste, low diacetyl, and ability to ferment in a wide range of temps. Look for US-05 to be the next popular dried yeast.

This yeast can be pitched directly, but if you prefer to rehydrate, the instructions are below.

Sprinkle the yeast in a minimum of 10 times its weight of sterile water or wort (we suggest 4 oz) at 70°F to 77°F (21 to 25 °C). Do not stir. Leave to rest 15 to 30 minutes. Gently stir for 30 minutes, and pitch the resultant cream into the fermentation vessel.

*See the technical data sheet below for more information on rehydration, usage and storage.

Always keep the 05 on hand
The o5 has been a go to yeast for several of the ales we brew and we have always gotten great results. We nicknamed it the NoFale yeast as it always produces great beer
