Yeast and Fermentation / Re: Re-using Yeast for Starters
« on: December 07, 2011, 07:59:20 AM »
On Sunday I racked a stout using Wyeast 1084. I had a yeast cake with about 1/4" of beer on top. I swirled the carboy around to mix with the beer and to loosen up the cake and then poured it into a 12oz. bottle. MrMalty says use 3.8oz. in my Scotch Export. Should i be mixing as stated, or should i harvest only cake? What role does O2 play at this point?
Also, when You talk about washing the yeast, could you elaborate how this is done? I mean, is it simply a matter of mixing with clean water; settle out and rack off the liquid in suspension?

One thing I would suggest for a Pilsner: use Pilsner malt  :)

Yup, agree. Someone gave me 10lbs. of golden promise, so I need to find something to make with it. Got any ideas?

Makes sense. Right now the chill water input is on the sam end as the hot wort input. Do you think switching chill input to the output end of the wort would make any difference?

I am using 3/8" copper tubing, but was thinking about going to 3/4". I would obviosly need to use a bigger diameter hose and reduce to be able to hook up to my hose bib. How much of a difference whould I see? Can I chill using less water; would it go faster?

Since I am using a RIMS, i dough in a couple degerss lower (Celsius) and come up to rest. Reading this thread raises a couple questions i have:
Since strike water is usually pretty close to mashout temperature is there some denaturing going on when I dough in/mixing?
And, if you rest at a higher temp. for a long period will you get less body? I am always curious when i look at other recipies how much mash times/temps vary with the same style.Can anyone recommend some reading that helps "demystify" mashing?

Getting cold break in your fermenter is no big deal.  There's even evidence it can act as a yeast nutrient.  I don't know of any commercial breweries that worry about it.
Yeah, I was reading a trhead the other day saying the same thing. And to be truthful, I dont have a problem with how my brews are turning out so I wont fix what aint broke. Thanks again Denny.

Right now I use a Blichman Hopblocker in the BK. After my boil I let the hot break settle for about 30 minutes then the wort is pumped thru a cfc on its way to the fermenter. Problem is I get all the cold break in my fermenter. I was thinking about recirculating the wort by pumping thru the cfc back into the kettle to create a whirlpool; keep recirculating thru the cfc till I am at (or close to) pitching temp. Then do my transfer. What do tou think?

Ok OK I get the point! I'll make a starter. You guys are demonstrably nuts! But thanks for the good input-all points taken.

I did a RIS a few years ago with similar results. I "fortified" it with grain alcohol. Invert sugar works well, but a little late for that. wish I could tell you where i found the calculator for adding Everclear. Maybe someone here can help.

When using yeast nutrient, when do you add and how much?

I add a pinch (maybe 1/8 tsp.) to my starter wort.
OK to boil?

I recently had a new HVAC put in my house and had them leave me the 3/4" copper tubing going to the old outside unit. Looks like there is oil on the inside. would this Acid#5 work for that? Was thinking about making a wort chiller with this.

For my mash tun, I inverted the keg(gle) and cut the bottom out the diameter of a plastic bucket lid. Had my welder beer drinking dude put a reducer in the sankey flange and I put a foldable false bottom in. I get every drop of liquor that way. My BK is a 15 gallon SS pot fitted with a Blichman Hopblocker. Again had my welder beer drinking dude weld a 1/2" close nipple on the sidewall and make a  SS dip tube welded to a 1/2" blichman quick connect. after my boil, I give it a stir and let it settle for about 30 minutes then pump thru the CFWC. My HLT has about 6L of deadspacewhich I just have to factor in, but would like to have my welder beer drinking dude fit it with something closer to what you have.
