I found a pear wine recipe on homebrewit.com and have placed
everything required in the primary pail. This recipe produces one
gallon of wine. After 24 hrs it calls for "one package of yeast, good
for up to 5 gals." All I have here at home is a half package (little
less than an oz) of Lalvin's Bourgovin RC 212 yeast. Is it OK to use
just this half pkg for this small batch? Any assistance would be
appreciated...thanks in advance. Kim

I don't use Lalvin, but one package of Redstar dry yeast is 0.176 ounces.
That is sufficient for up to 5 gallons. If you make a yeast starter, and let
the colony propagate before pitching, you can probably use it for more. In
an aerobic environment yeast will grow, and --- theoretically --- one yeast
cell could be used for any size batch. In practice, your wine might spoil
before the yeast colony is large enough, but I think 1/2 package of any
yeast should be more than enough for a one-gallon batch.
