Safale US-05 American Ale Yeast


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 is marked as directly pitchable yeast and there are no rehydration instructions.

Some instructions for rehydrating yeasts: Suspend yeast in 4 oz of warm water. Do not stir. Let stand for 15 minutes. Stir gently. Add an equal amount of wort to your solution. Cover, let sit for five minutes, and pitch.

  • Im useing this yeast on Triple Titus Ceasar. It has been in the wart for 9 days with no action. Do I need more yeast? Stan

    Before adding more yeast, check the gravity of the wort to make sure that fermentation didn't happen and there wasn't a leak in the fermentation seal where CO2 could escape.  It's very rare that US-05 doesn't work, and more often it's a leak in the fermentor.  The best thing to do is check the gravity against your original gravity, and if it has been fermenting, then add your dry hops!  If there is no change in the specific gravity, then you'll have to pitch another pack of yeast.
