The Pub / Re: Give it up for Michael Jackson....

I appropriated some unused servers for a project one time only to discover that their host names were BillieJean, Thriller, BeatIt, etc. In keeping with the MJ theme (almost) I renamed them Avery, DryDock, LeftHand, etc. The big slow hunk of junk with all the disk drives we used for backup on that project got renamed to Coors.

Just one more, why not be DD for a brewery tour at your local brewery hotspot. Better yet, get your spouse to do it so you can imbibe as we'll!

As regards a different lesson learned, I found that tipping it upside down to drain it after the boil is done and hoses are disconnected, it doesn't always drain well, and if left outside in the unheated garage it can freeze and burst the coil.  So now I keep it stored in my heated basement.

As to the draining - I rotate my IC after use so that all the coils drain.

Whoops!  Sorry, I didn't mean to suggest covering the pot during the boil, just in the run up in temp to boiling and during chilling.

All Grain Brewing / Re: Does shape of Tun matter?

This is because the amount of wort lost to the grain bed is directly proportional to the amount of grain. 

this implies the percentage and hence efficiency should be the same.  to lower the efficiency it would be wort lost is proportional to the amount of grain raised to some power. which may be the case. (in other words amount of lost wort increases faster than the amount of grain increases.)
I see where you're coming from, but you're making it more complicated than it is.  Essentially, for a 10# batch you lose 1.2 gallons to the grain bed, or 16% to hit 6.5 gallon pre-boil.  For a 20# batch, you lose 2.4 gallons, or 27%, to the grainbed. So, the amount lost increases faster than the total volume increases, but the amount lost is proportional the the grist weight.

So you're assuming the same pre-boil volume in both cases.  That makes sense. 

FWIW, I did an experiment that I posted about here some time ago where I brewed two batches of the same beer, but I doubled the second batch's grist in the same mash tun.  I was surprised to find that the larger grist retained significantly more water per pound of grain.  I'll have to repeat that sometime because I don't really believe the results and I think I probably made a measurement error somewhere.

I'm also in the Denver area and I typically get 1.5 - 2.5 gallons per hour evaporated during the boil.  Your boil off rate is probably not noticably impacted by humidity, ambient temperature, air pressure, or liquid surface area, except where those parameters might impact the efficiency of transferring heat from your heat source to your wort.  However, all of these parameters can be in play during the times you're not actually boiling, like when you are heating to a boil, or when you're chilling.  If you're getting a lot of undesired loss at these times, you may want to cover your pot.  But watch out for boilovers!

Thinking about this a little more...  The ambient air conditions won't make any difference actually while boiling, but in the run up to the boil and during chilling it might.  Does it take longer to get to a boil on the days where you have greater boiling loss?  Perhaps cover the pot while heating to a boil and chilling.  Watch for boilovers while heating, of course...  I sometimes heat my wort this way - I use a remote probe thermometer with an alarm set to 195F to let me know when I'm close to a boil so I can remove the lid prior to any mishaps (wort boils around 202F here).

Yeah, a teaspoon - "One million, four hundred eighty-five thousand, six hundred two; One million, four hundred eighty-five thousand, six hundred three; What, honey? Crap, lost count..." No wonder it was so accurate...   ;)

Well, if you don't consult the Mayan calendar, then you might ending up dramatically changing your hop utilization as you try to fiddle with the boil volume.  But instead of doing a kabuki dance, why not plan to overshoot your boil-off target and then top up if needed?  That's what I do, but I generally have a good feel for what the boil volume looks like and I fiddle with the burner (though never my boil time) and I usually hit my volumes dead nuts.  5 gal exactly yesterday (to the accuracy of my measuring spoon).

If by second edition, you mean _The New Complete Joy_ and you're comparing it to the third edition, there are quite a few differences, particularly in the recipes.

Don't fear the foam (i.e. you don't need to rinse and arguably rinsing exposes your equipment to possible contamination).  

I use Star San to sanitize my counterflow.  I pump the sanitizer through with my autosiphon.  The sanitizer is still in the coils when I start the beer through, so I run off the first bit onto the ground until I see beer coming out, then capture the chilled beer.

My wife finally found her gateway beer.  Actually it was pear cider.  Our local beer hut stopped carrying the only wine they had that was decent so she was forced to try something on tap - the cider.  From there she has discovered wits and hefeweizens.  Now *she* suggests going to brewpubs.   :)  But she put a hurtin' on my pumpkin weizen.  :(  Just have to make more  :) :) :)

Even before her beer conversion, she was hip to the coolness of the beer crowd and liked hanging with them.  There's a YouTube video out there with Sam Calagione talking with Ken Grossman where Sam says that he likes the brewing community because it is 98% a$$hole free.  Maybe the clip is from Beer Wars?  Anyway, I can't agree more.

There is a lot more to it than temp.  Their yeast may be good at those temps, but it could be other factors too.  For homebrewers, keeping it cool is a lot more important due to the size and shape of our fermenters.  The pressure in larger fermenters suppresses the formation of esters and higher alcohols, so unless you are fermenting under pressure, keep it cool.

Are you talking about pressure due to the depth of the fermenter, or do breweries actually pressurize their fermenters?  Or maybe the fermenters are sealed and pressure builds from the fermentation?  I haven't intentionally fermented in a corny under pressure, but it might be an interesting experiment.

So it seems that the brewers who heed the no-beers-while-brewing rule follow it about as well as the rules on speeding.  ;)  I'm sure none of us speed either.
