Yeast Starter Questions

[VikeMan]

The fields turn red when I try to increase my starter volume. See image for example. And when I adjust the volumes, the DME needed increases.

I see. But it's still not telling you how much DME you need for step 2.

And BTW, you probably don't want to increase the starter volume to the point that it warns you about inoculation rate. I wouldn't normally recommend going below about 25 million/ml. Usually, when you run into that issue (too low a rate), that means you should probably either increase your starting cell count (i.e. use two packs) or use more steps.

I wonder if the 101 g is for the whole 4 l of wort?

Of course you could use a recipe calculator and only add DME until you get to 1040 for the volume of water used.

Do you mean 4.5 liters? That would be a gravity of ~ 1.008. So that can't be it.

And if we assume 101 g in the first step (1 liter), that's about 1.035. So... the DME for the second step is missing.

In brewers friend calc, the first liter requires 96g, and the 4 liter requires 383.4g. So I'm guessing the 101 is only for the first ltr.

Seems like 96 - 101g of DME is the per-liter standard.
