    I am stepping up some Brett cultures. I'll share what I've done and you can either learn something or teach me something. I'm cool with it either way. All starter wort is 1:10 DME/water for what should be around 1.040sg.

    Fresh wort with Brett C pitched. Note color.

    Another 18 hours and I've made another starter and pitched Brett B to it. Now you can really tell the difference. At this point if you swirl the Brett C jar it gets very cloudy and creamy.

    Since the Brett C had real slowed down by this morning, 48 hours in, I decided to go ahead and step it up and put it on a stir plate. The original starter was ~200ml. I am adding that in to ~800ml of new wort.

    I always fill my vials back up for next time. That might be all I do with the Brux right now. The C is going in a Flanders Red style beer that is currently fermenting with mixed Belgian sacch.

    Another 12 hours and the Brett C is quite active, keeping some foam up even on the stir plate.

    Meanwhile, there is very little change in the Brett B.

    Brett B still slow, but with a slightly noticeable change in yeast volume and consistency.

    After stepping up the volume to hopefully encourage some growth. You can see the beginning of separation at the top. Getting very slight CO2 production now.

    All the while the Brett C is still taking names. Another step up.

    Wow, such a big difference in personality. Is that typical?

    I don't know. I seems like I recall all of my Brett to be a little slow in the past, but this is my first time keeping up with it.

    Ok, as of this morning the 2l Brett C was starting to flocculate on the stir plate. I transferred it over to a growler and started the B up on the stir plate, hoping to wake it up a bit.

    brett b has always been a slow, lazy yeast. it ferments fast enough, but growing and cleaning up takes forever.
