13-14 oz is WAY too much. When stepping up from old, stressed slurry, you want to start with maybe 50 mL.

Second, a packet of dry yeast is going to outnumber the yeast you want by a factor of a hundred or so. You probably won't see any difference from just using the dry yeast in your beer.

General Homebrew Discussion / Re: Priming Sugar Data Inconsistency
« on: March 04, 2010, 11:39:18 AM »
I've never checked the "density" of either sugar (and as several people have pointed out, that might not even be possible to do with any repeatability). On a mass basis, though, the conversion is very simple:

The molar mass of sucrose is 342.3 g, and glucose is 180.2 g. Fermentation of sucrose produces 4 moles of CO2 and glucose yields 2 mol.

2*342.3/4*180.2 = 0.9498

So about 95% as much cane sugar as corn sugar, to produce the same amount of CO2. Obviously this assumes the sugars are completely dry.

This has been a really helpful thread for me!  Can anyone comment on Rahr 2-row?  It seems to be the cheapest.  How does it compare to great Western?

I can't comment on Great Western, but Rahr is great stuff. Much better than Briess IMHO; those are the only two I have experience with.

I can hold my breath for four minutes.

I'm also really fast at mental math, but somehow that never comes up at parties.

All Grain Brewing / Re: For those that measure mash gravity

The refractometer is calibrated on brew day once with a drop of tap water.  I used to have to adjust it a lot when I first got it, but it rarely needs adjusting now.  I try to remember to check every time, but it's conceivable that I got lazy once or twice.

I was more concerned that it might have some sort of linear error. Have you checked a known-Brix solution?

FWIW my last three single-infusion mashes were at 89%, 95%, and 94% of the values from Kai's chart. For the 89% batch, I don't have a lot analysis, so it assumes 80% DBFG and may not be accurate. The other two were domestic 2-row and are relative to the actual potential extract.

Edit: I should add that these are without a mashout.

What cracks me up is people who can get drunk on light beer.

I think I get drunker on light beer. Much more alcohol per unit of beer enjoyment.

Are you checking your mash pH? 2-5°P low seems like a lot to me, especially after 60 minutes. My mashes are always within about 1°P of the theoretical values.

Is your refractometer calibrated?

I just got a Barley Crusher and brewed an APA back to back, first with the default setting, then with it at 0.030". Mash efficiency went from 79% to 87%. I did have a slow sparge with the tighter gap, but I've used Kai's spray-bottle conditioning method since then and had much faster runoff. Running the pump wide open fast, actually.

How can they be cannibalistic AND humanoid? Unless they eat each other but not people - but that doesn't sound like a very good movie. No, the entire premise seems flawed.

My alkalinity and hardness are both over 300. So step one for me is always deciding how much to dilute.

Michael: And so you just finished off the bottle?

Lindsay: Well, I had to. It’s vodka. It goes bad once it’s opened.

Michael: I think that’s another one of Mom’s little fibs. You know, like “I’ll sacrifice anything for my children.”

I believe confining any creature to a space other than it's natural habitat is inhumane.
Absolutely. Not a fan of zoos.  :(

Or dogs, right? ;)

I guess it's not necessarily limited to the internet, but advancement in technology like computers, video game systems and such.

It's a seeking out of stimulation. Kids' brains *need* to be challenged in order to develop properly; it's hard-wired. And no game of stickball can match the stimulation provided by an XBox.

OK, so some of it's laziness.
