Yes, absolutely. I saw great results from my trials.

Do you use any chalk as buffer to allow for more lacto growth? Some people use 2g/l.

I don't think so. Just Low Oxygen wort, CO2 purged Pima and time.

What's the sulfite load in the lodo wort?

My dose these days is 30mg/l. But thinking of lowering it again.

Very nice witeup Bryan! I enjoyed reading it!

There are a few more final frontiers but this is definitively a big step towards the goal.

Any reason why you didn't throw in a handful of malt and proceed?

Indeed it does take a bit of time for a culture to develop and settle, but I find it faster this way.

FYI the Hefebank Weihenstephan sells the cultures, for those in a hurry.

Sauergut is the most undervalued aspect in German brewing.

Here is my reactor V2 when it was made (you've probably seen it already).

Looks Great Nico!

The first 2l batch was more or less proof of concept(which got the actual malt), and served for the "starter" in the main batch. I suppose I could have skipped it and went directly full scale, but I used the 2l batch again as the testing for the big batch. Once I noticed better sugar extraction, and fantastic flavor, then it was ON.

I have seen the cultures at Hefebank, they pique my interest.

I agree, so undervalued, but such a big contributor to flavor and character,

I find it's best to keep your own going. It adds character and a bit of a signature ;)

Any reason DME shouldn't be used for this?
