When I brew I use C-Brite Cleanser.  When I bottle I use Star San.  As you can see from my above post, my bottles go through a rigorous cleaning before bottling.

What's the favorite out there?

go to general homebrew and look up sanitizer comparison

I don't typically re-use yeast, but I'm interested in starting.

How does 34/70 look to you all?



My transfer process doesn't leave behind much beer in the primary.  I used a sanitized ladle to scoop this out of the cone (I currently ferment in one of these: http://www.ssbrewtech.com/collections/fermenters/products/the-brewmaster-bucket).

I'm considering pitching some of it into a marzen in a few weeks.
I have repitched about that much 34/70 slurry up to 6 generations (using shaken starters) with good results.  Probably could have gone more.
Many of us would be on a strict liquid diet if it weren't for pretzels.

Well, I pitched about 80% of what I harvested into a two liter starter last night (skipped the stir plate on this one but oxygenated for 25 seconds prior to pitching).

I pitched it at 8:45 last night; below is what it looked like 10 hours later at 6:45 this morning. 

I stuck it in the fridge before I left for work about 90 minutes later.  The plan is to decant and pitch into 5.25 gallons of marzen on Sunday morning.

You're fine... beer... yadda yadda...

Going to Baltimore? You and Sean want to hop around town during some of the most popular seminars again? I hope so.

I'm planning on it.

Hell yes.   

I've never been to Baltimore.  Have to do some research and see what's worth checking out

I was at every one of those seminars! Ask me anything, then give me an hour to answer!

I'm most likely going to have to miss Baltimore. Things should be getting pretty busy around then.

Well, I hope you can make it, but you've got a pretty good excuse. 

How's everything going at 2MBC?

Not great, obviously, but we should be in good shape for the spring. It's really down to the weather at this point.

Narcout,

Why did you refrigerate so soon?  I typically leave my starters on the stir plate until they ferment out.

Did not know that it was no rinse. Thanks.

At proper dilution, it is no rinse.

I was hoping to realize some of the supposed benefits of pitching the starter at high krausen without pitching the entire volume of the starter.

I've been experimenting with pitching an entire 1 liter starter at high krausen into ales, but I like to pitch more cells for lagers and couldn't bring myself to pitch a full 2 liters.

For more info, search this forum for the term "ergosterol" by user "s. cerevisiae."
