10 gallon batch and only 1 vial of yeast

[DancingBull]

Howdy,

I am doing my first 10 gallon brew (wheat beer extract) and they only had 1 vial of WLP300 yeast, (I will be dividing the batch into 2 and putting them each in their own carboys.)

I also picked up some priming sugar as my friend said I can propegate the yeast i have to make more.

How is this done and would I have enough yeast to cover this volume?

Thanks in advance!

Make a starter, as usual, but make it double the volume. Yeast double in about an hour if they have sufficient oxygen and nutrients, so it should only take an extra hour or so for them to do the extra reproduction for the larger starter volume. No problem at all.

If you weren't making a starter, and you pitched only one vial into 10 gallons, well... I wouldn't be holding out much hope for that batch.

Do a starter and build up the yeast. I wouldn't use priming sugar for that though, I'd use DME.

+2, use some DME and make like a 1 gallon starter. Pitch the yeast after 24 hours of that starter going. As long as you're sanitary you shouldn't have a problem letting the wort sit.

+3 on the large starter.
