Nope, sorry but there's no key.  I find that if I hover my cursor over most icons it will tell me what they are.  Does that work for the one you're seeing?

Due to some concerns about Fermcap, I've gone back to that.

Denny, what sort of concerns do you have with Fermcap? I use it often, but don't want to if it has an adverse effect.

From what I've been able to discern, it's really meant to be filtered out before the beer is consumed.  There are concerns about kidney blockage.  Admittedly, at the amounts we use it seems unlikely to be a problem, but I have enough medical issues already that I'd just as soon limit its use as much as possible.  I've pretty much stopped using it in the kettle, whereas previously I would add a fair amount to every boil.  With a bit of vigilance I can control the boil with the valve and a spray bottle.   I also don't add it to fermenters as a matter of course as I used to.  If I can't control the fermentation some other way, I'll add the least amount I can get away with when I need it.  PLease understand that I'm not trying to tell anybody what they should do.  This is simply my own decision.

I was trying to collect 5.5 gal, but I think I don't think beercalculus is very good at factoring that in.

This is actually the first time I have tried fly sparging, I usually batch sparge with the same results. I was trying the continuous sparge to see if investing in a proper fly sparging set-up might help.

According to Kai's formulas, I had a conversion efficiency of 99%, but I'm not sure I understand how that could be possible. Does his table assume qts of water per pound of base malt? or the entire grain bill?

If you're shooting for 5.5 gal. in the fermenter, then 1.066 is the estimate from PM.

I usually include 1 lb of C-120 in my 10gal Irish Red recipe.  If any of you have used Weyermann CaraAroma in anything I was wondering if it would work well in place of C-120?

Dave

CarAroma is much lighter.  It's like carapils IIRC.

no its actually ~130L

I say go for it - it won't suck

Thanks for the correction, Paul.  I was thinking of carafaom.

I don't think so

BINGO!  When you get a tank refill, it should come with a nylon washer to go between the tank and regulator.

I drain until the mash level is just above the grain, then start siphoning in sparge water at a rate as close to equal as I can get it. I definitely started my sparge at a rate quicker than I wanted (built up about 1-2 gallons on top of my grain bed) but I don't think that should have add a dramatic impact?

Try batch sparging next time.  That will show you if your lauter system is the culprit.  Have you checked your conversion efficiency via Kai's website?

For one thing, I think the OG estimate was off.  I get 1.066 in Promash using your grist.

Hmm, I was wondering if 12 lbs wasn't light for this target. What efficiency considerations does promash make? Using data from Palmer's book and a 75% efficiency I calculate 12lbs*27ppg/5.5g=1.059. All of a sudden, I am starting to think that beercalculus includes specialty grains in their calculations for OG....  Anyone else experienced this? Maybe this is my only issue, not doing the math the long way.

I entered 12 lb. of 2 row pale at 36 ppg and 2.5 lb. of C60 at 34 ppg to simulate your grist.  At 75% I get 1.071 for your OG.  I made a mistake earlier and had PM set for 5.5 gal., not 5.

That's an interesting point, Denny.  As I understand it, both PH and Temp are factors... but that does lead to questions about how it isn't an issue in decoction mashing.

From How to Brew: http://www.howtobrew.com/section3/chapter17.html

Quote to note from chapter:
"Sparging is the rinsing of the grain bed to extract as much of the sugars from the grain as possible without extracting mouth-puckering tannins from the grain husks. Typically, 1.5 times as much water is used for sparging as for mashing (e.g., 8 lbs. malt at 2 qt./lb. = 4 gallon mash, so 6 gallons of sparge water). The temperature of the sparge water is important. The water should be no more than 170°F, as husk tannins become more soluble above this temperature, depending on wort pH. This could lead to astringency in the beer."

For one thing, John is talking about fly sparging .  The reason you can do decoction mashes is because the mash pH is low (see the part I bolded above).  The real issue in tannin extraction is the pH getting above 6.  It if stays in the proper range (as it almost always does in batch sparging) the risk of tannin extraction is very low to non existent.

This is a brand new taprite regulator. I tested all connections and no leak what so ever. My c02 tank would be empty for sure if it was a leak. I have no idea if its leaking inside the diaphram.  My old one sounded the same to Me. I'm assuming the new one is fine. I put bubbles everywhere. Also if it was a leak the sound would continue but this goes away in a couple minutes.

Maybe too obvious, but is there a nylon washer between the reg and the tank?

Sparging with boiling water is not a good plan.  You are likely extracting harsh tannins, which may or may not be the "starchy" flavor you are referring to. 

It's the pH, not the temp, that's the culprit in tannin extraction.  If not, no one could do decoction mashes.

I have a march pump and it works fine.  I don't know that there is much of a difference between the march pump and the chugger pump.

All of them will handle boiling temps, even with the plastic head.  I've had one with the plastic head for years and it's been great.  I'm sure the stainless head is cool and looks nice, but it's definitely not necessary.

Agreed.  I use the standard March 809 HS and it's worked great for me.

Here's my recipe....no Special B, but I used 2 lb. of D180 syrup.

http://www.candisyrup.com/uploads/6/0/3/5/6035776/dennys_400th_-_variation_001.pdf

Thanks Denny!  What do you think the Caramunich provided?  Also, why the turbinado sugar in addition to the D-180?  Thanks for the link.

The CaraMunich gives it body and richness.  The turbinado was partially to increase the sugar % and partially for flavor.
