I only got about 2/3 of my US05 packet into 5.5 gals. of wort. Should I open another packet and add more? I did not rehydrate as some say it’s not necessary and my beer has been turning out fine. Thanks in advance for your advice.
What was the gravity of the wort?
OG is 1.047.
I think you’re good.
I agree; you’ll be ok. If you had rehydrated the yeast you’d be even safer.
For those that don’t know, when you dump dry yeast into wort many of the yeast cells die before they have a chance to do anything. They can’t rehydrate effeciently in wort because of the sugars. By rehydrating the yeast in plain water before pitching you get a much higher survival rate. More yeast in your pitch means less stress, fewer off flavors, and lower risk of infection.
