Kegging and Bottling / Re: Pinic tap hose length?

Yeah, you can carbonate at the normal pressure, then reduce it for a short period (a couple hours) to serve at lower pressure.

10%/hour, with a 75 min minimum boil, is what I shoot for. Granted, this is at 10 psi, so all kinds of things are wacky. At lower elevation I'd imagine you could boil off less given the higher temperature.

As long as your cooler has a drain I'd do a braid instead. Easier to clean...

Even 4' is pretty short assuming it's 3/16" ID tubing. I'm surprised you're getting a good pour. If you have to go shorter, you'll probably want to reduce the line diameter to prevent foaming. You can also put a little restriction in the line or dip tube: https://www.homebrewersassociation.org/forum/index.php?topic=20654.0

All Grain Brewing / Re: #5 Gravity Questions
« on: March 24, 2015, 09:32:00 AM »
9.62 lbs. of grain. Mash thickness of 1.665, mash volume was 4 gallons, sparge volume was 3.37 gallons.

In case you need it, 2.75 gallons first runnings, 3.5 gallons from sparge.

You're losing ~5% (0.15 gal) to either dead space or incomplete lautering of the first runoff. Figuring out a way to get all that wort out would be a good start if improving efficiency is the goal.

Taking a step back, though, your measured gravities are *really* close to what you expected. So regardless of what your mash efficiency actually is (somewhere around 80%), it's very nearly what the recipe was formulated for.

The Pub / Re: What's the Weather Like Where You Are?

Man, it is so warm here
I am already into the Maibock.

It's definitely caught me by surprise. I just kegged the doppelbock; the maibock hasn't even been brewed yet.

All things considered, the abv calcs are estimates. What's your experience with the etimatates vs. actual Sean?

In the batches I've actually had tested, which is 200 or so, but all in the same brewery, the estimate 0.525(OG-FG) was always within ±1% and almost always within the ±0.3% the TTB requires for labeling.

What am I missing? Is the FG vs OG not an exact measurement of ABV?

Not even close. It's an accurate measurement of how much dissolved extract changed during fermentation. Anything beyond that requires making assumptions about the composition of those sugars, and how much ethanol was produced as opposed to CO2, yeast biomass, etc.

General Homebrew Discussion / Re: try at batch sparging

As usual, I will pimp this link: http://seanterrill.com/2013/10/05/batch-sparging-calculator/

The single best thing about batch sparging is that it's entirely predictable.

Consider that if it were truly 1.074 and pretend your FG was 1.020...this would be a 7.09% beer. If the OG truly was 1.072, you'd end up with 6.83% ABV.

Except that we aren't measuring the ABV, so all you could honestly say in either case is that it's probably between 6.5% and 7.5%.

Bell’s, we just don't think you should have filed it. We believe that it lacks merit, and the impact has been an unfortunate, costly, and lengthy heartache for all.

I really hope this has all been a publicity stunt and that they don't really think they'll be getting a trademark on the word "innovation" in the brewing industry.

Real Attenuation = 0.82 * Apparent Attenuation

Beer A would have more sugars due to also having more alcohol to cancel out the gravity contribution. Though the real extract would be ~1.019 for A and ~1.017 for B, so most likely you wouldn't even be able to tell the difference.

It could be either, depending on whether the hydrometer is calibrated to the top or bottom of the meniscus.

How many of the Pros here have attorneys?

Yo. I'm not sure how you could responsibly run a brewery without an attorney on retainer, and Colorado is an extraordinarily beer-friendly state.
