Yeast and Fermentation / Re: Another Starter Question
« on: April 17, 2014, 11:08:23 AM »
I do not have to prove my claim.  There is ample peer reviewed scientific data available that shows that leaving beer with the trub is not beneficial to flavor.  It is those who are making claims against this body of evidence that have to support their claim via peer reviewed data from scientifically-executed experiments.

Saying that there's evidence to support your position isn't the same as citing your sources. Neither you nor the putative opposition in this debate that you really, really seem to want to have has presented any evidence.

Those who claim that the use of a secondary fermentation vessel to clear and age beer is out of date and more harmful than beneficial have yet to put forth any real scientific data supporting their thesis.

Nor have you supporting yours.

Four judges? Showoff. :P

I was told that 1056 is a crazy good yeast that will get through almost any 5 gallon batch...

This is undeniably true. If "getting through" fermentation is your foremost concern – if, for example, you were a new brewer with questionable sanitation and a limited budget – then pitching one pack is the cheapest and easiest way to ensure you'll make beer.

This is an easy fix… Go into your BeerSmith settings and change the attenuation for 002 to 77%. Problem solved. ;)

Point being that recipe software can't possibly know how a given strain will attenuate for a given mash schedule in your brewhouse. Only you can tell it that.

That could be scary if reading late at night in bed.

Nah, Denny's a great guy.

Though it was a little weird that he *insisted* on being the big spoon...

All Grain Brewing / Re: Mash efficiency survey
« on: April 15, 2014, 05:25:20 PM »
For a single batch sparge, it ranges from about 63% at 1.110 to 85% at 1.038. Boiloff is 15-21%.

As long as you get full conversion in the mash, there's no reason to have any error at all in estimating batch sparge efficiency. http://seanterrill.com/2013/10/05/batch-sparging-calculator/

Beer Recipes / Re: Thoughts on another IPA
« on: April 15, 2014, 04:38:56 PM »
While a FWH addition will add as much IBU (slightly more, actually) as a beginning-of-boil addition, some brewers say that it *tastes* like a 20 min addition.

I don't like CTZ as a dry hop, and I would ditch the 40 min addition (or move it to 10 min), but otherwise it looks like a solid recipe to me, and I think it will at least get close to your description of what you're going for. Is this a 2.5 gal batch?

I have no idea, but my guess would be that the content is only licensed in certain countries.

Yeast and Fermentation / Re: Fermentation Timing
« on: April 15, 2014, 09:51:44 AM »
A reasonable rule of thumb is 2°P/day of attenuation for ales, and 1°P/day for lagers. If you're seeing significantly less than that, then like SC said, you're likely under-pitching and/or fermenting too cool.

But without checking the gravity, I wouldn't assume anything.

Sean, sorry we couldn't get together.  Grand Rapids?  Or Portland next year?

Oh yeah, I'll be in Grand Rapids for sure.

Equipment and Software / Re: Looking for electronics help

Are these Neon bulbs still made? if so is there a "type" of neon bulb that it would be called that i could search for? Ill just replace the neon if putting an LED onto this system will be a pain. Im going to stop at radio shack and pick up a few LED's and a resistor to try with it either way. i think 1k will do it.

You'll also need a diode to rectify the current, and keep in mind that even at 20 mA, 120 V is 2.4 W… Radio Shack probably doesn't have anything big enough, at least not in stores.

Sorry I missed you guys, I heard it was a great conference. Someone had to make some beer this week though. ;)

All Grain Brewing / Re: Mash Sparge Combo
« on: April 12, 2014, 04:27:42 PM »
I had to do that in a very small brewery due to equipment limitations. I'd sprinkle the "sparge" water on top as gently as possible to avoid mixing, then drain the tun. It did buy us roughly a 5-10% efficiency bump depending on gravity. At home? Just no-sparge.

Does boil off and/or shrinkage affect the concentrations of the minerals I just added?

Yes. Just like with anything else in solution, it's only the water that evaporates, and the concentration of the solute will go up.
