I brewed a NB Oktoberfest all grain batch (5 gal) over the weekend. I was planning to use the dry yeast 34/70 but due to some Midwest weather event it did not arrive by brew day. So I went to my local brew store, and that only had two packets left but they also had 2 of the liquid Wyeast 2633 . So I grabbed the liquid yeast and made a 1.5 liter starter from one and a 1 liter starter from the other. I just Pitched them both at beer temp of 52deg.
I am hoping I have enough cells but one package was from May and the other dated just a couple of weeks ago. Both starters looked good and spent some time on the stir plate before sitting for a while. I made them on Saturday AM and pitched Tuesday afternoon.
My backup now of course is my 4 packets of dry yeast just arrived so I popped them into the fridge.
I have only made one other lager and had plenty of yeast for that batch (2 starters plus direct pitched one pouch).
I can always toss in a little dry yeast but thought I would give the two starters some time to see how they do.
Any milestones you guys can suggest that would indicate one way or the other if this brew will need more yeast troops to get the job done?
