Choice 1 - use mrmalty or a similar calculator to estimate viability. Then depending on what you find, make a small starter a day or 2 before brewing to ensure they are still alive. Also use mrmalty to approximate pitching rate.
Choice 2 - dose your boil kettle with 1/2 pack or so of the dried yeast per 5 gallons around 10 min before the end of the boil and let your fresh yeast use it as nutrient.
"Susan smiled at me, giving Molly the Female Once-Overa process by which one woman creates a detailed profile of another woman based upon about a million subtle details of clothing, jewelry, makeup, and body type, and then decides how much of a social threat she might be. Men have a parallel process, but its binary: Does he have beer? If yes, will he share with me?"
