Liquid yeast starter for a batch of 13 galons.

[Swaroga]

I use dry yeast most of the time. I used liquid yeast with a activator in it without doing the starter and it worked OK but had to use 4 of those packs.

I wish to do a real yeast starter for 13gal batch and all I find are tips for small batches.

Would you mind giving me some tip or direct me to where I can find some clear step by step guide ?

Thanks a lot.

Try out these calculators. It will take a little bit of play to see how they work.
