You forgot to put "overpitching" in quotes. 

 

hey - spoiler alert!

Good to know what the calculators say.

 

sure it's an estimate.  but would you track with the calculator up and down the scale?  I'd guess that even if the calculator is off in an absolute sense it does pretty well relative to itself.

Is there any truth to the thought that pitch rate may be a lot more flexible with a clean-er yeast like 001/1272/1450/US-05? As opposed to a yeast which provides a larger contribution to the final flavor profile of the beer. Like 3068, 3944, pick your saison/other belgian ale yeast?

I never thought about it that way but that is interesting.

i'm sure all yeasts are different and some are more flexible than others or another way to say it, more forgiving when it comes to optimal pitching rate.  i'd think beer style would be a determining factor as well.  some lagers you really don't want to mess up or you'll taste all of the off flavors thrown by an under or overpitched yeast.

10 gallons of 1.067 OG wort, ale yeast

start with a 60 day old wyeast smack pack stored properly

make one 2L starter and split, half for keeping, half for another starter

make another starter with half of the first starter to pitch into 10 gallons of wort.

 

How big should the second 1.036 OG starter be?  no using a calculator or calculations.

 

I have a pretty good idea but that's only b/c I basically just went through a similar step up.  Ask me in a couple of months and I'd be going back to my notes to check which would take me about as long as it would to just let the calculator spit out an answer at me.

How long do you keep the first half starter? Do you take that into account?

on the next time around sure.  in this case i do the second step a couple of days after the first step so there is pretty minimal loss.

Unpaid bills?

 

does this mean it's all over if someone else is putting stuff up there?  did they lose their site?

Looks like Kai isn't paying attention to his e-mails this week.

Someone put up a version here for a short time.  Save it for offline use and you should be good.

I'll have to try that later.  thanks.

I just tried the starter calc on brewersfriend.com (Kai's calc).  There's a huge difference between Kai and Jamil.  Looking to hit 375BB cells, Kai's calculator suggests 2.02L and Jamil's gives 3.82L.

IIRC Kai came up with his because Jamil's used some sort of extrapolation of data points from a non-agitated starter to get his growth results on the stir plate. I think Kai (naturally) actually tested his method. Kai has a page on his site that documents the method to his madness. Im sure my explanation sux so I should just stop talking and give you the link...
