I made a massive yeast starter for 10 gallon Oktoberfest. 2.5 gallon starter which I stepped up a week ago with another 2.5 gallons.
The yeast calc on Brewers Friend says I will have plenty of yeast for my Oktoberfest.
However, brew day got pushed back. We’re now going to brew on the 25th instead if the 18th.
I’m going to decant the starter wort off and put the slurry in the fridge for the next week and a half.
Do you think the cell count will still be high enough or should I do one more step up in the starter?
