My homebrew club is making a barrel aged RIS coming in at 1.110 OG. We want to use the same yeast for consistency and decided on Safale S-04. By all the yeast calculators and doing the cell count math, it will take 4 packets for a 5.5 gallon batch. I have used 2 packets, but no one in the club has pitched 4 packets at once. That's a whole lot a yeast for one time, I'm a little weary about that much at once. Does anyone out there have experience in this? Would re-oxygenating or adding nutrients a few days in benefit the fermentation? Any advice? Cheers!
