After a year and a half of being on the forum almost daily, this his now happened to me half a dozen times in just the past two days. Maybe the timing will give the server gnomes a clue...

All Grain Brewing / Re: Batch sparging big grain bills
« on: April 02, 2011, 05:42:07 PM »
That's a large enough volume and a small enough grain bill that I don't think there's any need to no-sparge it unless you want to brew a small beer with the second runnings. If you mash with 6.3 gal and sparge with 4.0 gal you'll have equal runnings and only take up 32 qt of volume in the tun. With 100% conversion efficiency that will get you 8.0 gal of 1.063 wort, 5.25 gal at 1.098 post-boil.

FWIW you are brewing a Belgian Ale .... Belgium is a country. You don't brew an America IPA.  ;)

Maybe you don't, but out here we do. These colors don't run, baby! ;D

1323 Greene St, Silverton CO. I was joking, but if anyone actually comes up to Silverton the beer's on me.

I missed happy hour, but the POW has live music if anyone wants to meet up with me there. ;D

This actually just happened to me for the first time today. Had to click reload 5-6 times before the page would render.

If you aren't getting full conversion in an hour I think your mash chemistry may be a little out of whack. As long as I get my pH in range I have >90% conversion when I start recirculating at 45 min.

I always mash longer than 1 hour. One hour is not long enough, IMO.

Long enough for what?

Questions about the forum? / Re: Getting weird "index" downloads

Simple things first: is there any chance you're accidentally holding down whatever key would cause you to download a file instead of rendering it in the browser? By default I think that would be Control.

Extract/Partial Mash Brewing / Re: Partial Mash Vacation
« on: April 01, 2011, 05:29:27 AM »
I did something similar recently. AG, but a stovetop partial boil. Total time including cleanup was 3:40. It's amazing how low-maintenance a brew day can be once you have everything sorted out. I remember my first few brewing sessions as 8 hour debacles.

I pitched the yeast, cleaned the kettle, put everything away, then checked my watch. "1:30?! What do I do the rest of the day?"

All Grain Brewing / Re: Great Western 2-row vs. Pale Ale
« on: April 01, 2011, 02:14:16 AM »
Depending on how darkly kilned the pale malt is, you may not notice any difference. If it's particularly dark (>3 SRM) you may notice a slightly sweeter or maltier character. If the recipe has a lot of character grains, that difference probably wouldn't even be perceptible.

On the subject of the wort densities being different, I usually wait 10-20 minutes after the whirlpool to transfer so the break can settle.  Is it generally thought this will result in vastly different gravities in the first and second half of the wort?

I'm with Denny on this one. I don't know exactly how long you'd have to boil to homogenize the wort, but I don't think it could be more than a few minutes. Once that happens you just have a uniform sugar solution, well below the saturation point. It shouldn't be possible for anything to precipitate out, so the entire wort column will have a uniform density.

Well technically lagering just means "storage", not cold storage. ;)

General Homebrew Discussion / Re: Is a refractometer worth the $$?

FG readings with my hydrometer (I double checked calibration) 1.025 and 1.024 after adjusted for temperature.  None of them come that close, off by about 5 points across the board.  This is similar to what I saw before.

Thanks for posting this, Tom. The problem you're seeing is due to the fact that the OG range used in the initial data set was 8.8-24.3°P, and outside that range the correlation falls off pretty quickly. I'm seeing this with all the very high- and low-gravity data people have sent in. The other major issue I want to address is that I didn't test any worts with (real) attenuations less than 59%, which I thought was a reasonable floor for typical beers - apparently I was wrong about that, since I've gotten several submissions with RDFs in the 40s. There's going to be a 3.0 release in the next week or two that will hopefully address both issues.

FWIW, the new correlation I'm playing around with (as of now) puts the FGs at:
A: 1.022
B: 1.021

Which still isn't "good enough" IMO, but it's getting there. How confident are you in the 25.5°Bx value? If you'd like I could incorporate it into the new dataset.

Also, how did you cool the sample? I've noticed that if I don't chill it in a sealed container evaporation can increase the gravity significantly. It might not explain the discrepancy in the spreadsheet, but I thought it was worth mentioning.
