They have lots of interesting data on that site...

The strange part is that those two lists overlap. Apparently they only survey about 200 counties.

Ah, true. With my centennial ale I laugh at Jim Koch's "more than a pound per barrel" hop utilization. But not by much.

I laugh at that commercial too. But then I taste a Sam Adams, and wonder where all those hops are going. ???

For a no-sparge, you can get a really accurate estimate of the pre-boil gravity as long as you assume 100% conversion efficiency. Given that, the only factor that impacts SG is the liquor-to-grist ratio. Kai has a chart here:

Since you want to dilute to 5 gal at 1.050, you need to collect 3 gal at 1.085. Checking the chart, you can see that requires a mash ratio of 1.44 qt/lb. Assuming 0.12 gal/lb absorption and no dead space, x is the grain weight in pounds:

3 + 0.12x = (1.44/4)x; x = 12.5 lb

For a given flow rate, you'd chill faster using the smaller diameter tubing. Greater surface area per unit volume. Doubling the tubing diameter will double SA, but quadruple V. So unless you can at least double the flow rate by using larger tubing, the 3/8" will be better.

To speed chilling, you need to increase SA/V, flow rate, and/or temperature differential.

It pretty much depends on what the bottled water is like and what your grist bill is.

And once you know the water composition and the grist bill, you might as well just add whatever salts are needed.

Think I'm going to ask for a refractometer and pH meter for christmas lol.

With a name like madscientist, I'd say you're pretty much obligated.

To get coffee flavor in a stout, I like to use roasted barley. It's a completely different flavor than black patent. 1-2% will keep it subtle. If you're going to add coffee directly, you might just want to skip it.

2 lb of lactose is too much IMHO. I'd keep it closer to a pound.

Yeast and Fermentation / Re: Problem with attenuation

The first thing to check would be the calibration on both your mash thermometer and the temperature controller. If you were mashing high and/or fermenting low, that could be the issue.

Ingredients / Re: Diastatic Power of Munich

Is this a catalytic reaction in that the enzyme is never used up or what?

All enzymatic reactions are catalytic. I think the recommendations for minimum diastatic power (35 Lintner or so) are based on being able to achieve full conversion in a reasonable amount of time.

Oh she it...  I feel a PV=nRT argument coming on...    :D

(Price)(Volume) = number of Real Tanks filled?

Four weeks is a VERY long timeline for an ale. If you pitch a standard amount of yeast, an average-gravity ale should reach FG in 3-6 days. Bottle three days after that and it should be carbonated well ahead of time. You'll probably even have a week or two left for cold conditioning to drop it bright. If your bottles aren't carbonated after 7-10 days, you're probably storing them at too low a temperature. 75°F or so is ideal.

Using one plastic bottle per batch will let you know when the beers have carbonated, without having to open them.

So if I am mashing 8 lbs of Munich with 3 lbs of malted rye I should be ok? Weyerman Munich.
If the rye is malted, it should be able to convert itself anyway. The Munich would just be insurance.

« on: November 25, 2011, 04:09:54 PM »
Japan on the other hand used more clay-rod technology. Less spewed up and about.

Never heard of it. Maybe "clad-rod"? The uranium oxide pellets are ceramic (the same as the RBMK/Chernobyl fuel pellets), but clays are organic.

Not that it's really essential to the point. I just wanted to make sure I wasn't further out of touch with the industry than I thought.

All Grain Brewing / Re: Racking under CO2
« on: November 18, 2011, 09:01:48 PM »
Are you just using CO2 to start the siphon, or do you also need to overcome the static head (i.e. have the fermenter and keg on the same level)? If the latter, you'll need to be able to pressurize the fermenter to 2-3 psi, meaning you definitely can't use a glass carboy, and even a plastic bucket might not stay sealed.

Yeast and Fermentation / Re: Lager Slurry
« on: November 18, 2011, 08:35:45 PM »
I'm picturing siphoning off the beer, dumping the carboy into cleaned and sterilized bowl and dividing this equally between two new 5 gal batches.

If the new beers are roughly average gravity, that would be pretty significant over-pitching - not that that's the worst thing to do to a lager. I've never had a slurry come out of a fermenter that was less than ~3.5 billion cells/mL. So even if your viability is low and the non-yeast percentage high, 200 mL is about the maximum you'd need for an average-gravity lager.
