My gut says you're correct.  Ideal conditions need time for phenomenon to occur.  The O2 is going to get swept out in the rush as part of a mixture of gasses.  But co2 settling (if it actually happens) would also take time.  Probably hours or days for a significant co2 layer to form on top of the beer.
Stratification of CO2 is a myth at the scales we're dealing with. You need a perfectly calm column of gas on the scale of kilometers for gravitational effects to have a significant effect on a gas blend.

The only problem with the split batch idea is limited fermentation control. I can use my Auber dual temp controller to keep my chest freezer at one temp only. The specs say 1007 likes 55-66 and 090 likes 65-68. So I could run ferment at 65, but that is the high end for 1007. Just wondering how they turn out, and may be tough to compare the 2 batches, as only one may be at the perfect temp...
65F should be fine at 1007. I routinely ferment it at ambient temps in my basement, so beer temp is typically mid 60's.

Eric, do you think that 1007 will work well with my grist: 9#pils, 2# Munich I, 2# Vienna? It is more of an IPA than alt for several reasons: color, OG, IBUS, etc. Beersmith has me at 5.0SRM, well below Alt levels, but I am not really concerned about the numbers, just the best option for this grist and brew idea. The only items I have yet to buy are the Vienna, and the yeast, picking those up on Thursday. Maybe I run this as another split batch, half 1007, half wlp090. Best way to find out what I like, right?
I think the 1007 will do a great job highlighting the flavor from the German malts, while staying out of the way of the hops. I like the split batch idea, too. I think no matter what you choose, you will end up with a great beer.

I was going to shop for grains online for a time but the shipping is making me think I should use my local store.

They dont have the full range of Dingemans grains but if I need some caramels or other specialty grains besides special B or aromatic i'll just use Briess or Muntons to supplement. Better to shop local I guess anyway.
I pretty much have to buy online, so I try to buy several recipes' worth of grains at once to keep shipping costs down.

had to look up Hammerschlagen.
+1 - It loosely translates to "Drinking game that ends badly"

Thanks for the feedback!

Not to mention that none of my yeast handling techniques ive tried along the way ever obviously improved the quality of my beer, except for using a fresh smack pack in an oxygenated nonstir starter, with autoclaved dme starter wort that had nutrient included. That method has given me the most reliability. Im also a new fan of gel fining the primary, so I'm fine with shelling out $7 for a new pitch. So is my LHBS ;-)

Maribeth Raines and Jeff Mellem used to sell a product called SuperWort.  I would love to know what was in that mixture.
Happy Cinco de Mayo everybody!  ;D

Not to try to change your mind, but I have brewed a "Düsseldorf IPA" before (basically an Alt brewed with an IPA hop bill using German Hops) and 1007 really highlights the "German" character quite well. It is a clean Alt yeast, and leaves a bit of that altbier fermentation profile. Either way will be fine, but I think the German yeast will really complete the style for you.

While I have no personal experience with an all-Brett beer, I have read/heard from several sour brewers that they ferment Brett at warm ale temps (68-72F). I think many wild beer brewers have come to the conclusion that the typical "Brett" character tends to come about from a primary Sacc fermentation that produces esters and phenolics that the Brett can convert into other flavor compounds. This explains why Brett-primary fermentations turn out so clean - they don't have much to work on to produce Bretty flavor compounds.

I do not see the advantage of just knowing the temperature continuously. I already know and record the temperature of my wort/beer at every important juncture, knowing any more than that is just more data that I wouldn't have use for.
Agreed. Those brewers who are high-tech enough to have a need for continuous temperature information, either in the mash or during fermentation, already have a mechanism to control said temps in response to any fluctuations.

And at that price point, you're competing with Raspberry Pi-based controllers which are a lot more robust. It's not that this isn't a useful product, but I don't see a niche in the marketplace for this at this price point.

That's good to know. I think I can use the method you do and really be able to have 4-5 batches worth of grains on hand at all times.

I personally think I can make 1 lb. of all the specialty grains i'd need last for a long time at the increments i'd need.

When scaled down my recipes need only 1-2 lbs. of base malts and between 0.05-0.2 lbs. of specialty grains.

What do you store in?
If they come in good-quality ziploc bags, I just leave it in those. Otherwise I move it to a 1-gallon ziploc storage bag. I've been meaning to get a couple of Gamma seals to use to store my bulk grains in 5-gallon buckets, but for the time being the grain stores just fine in the sack for a year or so.

Good read, Marshall.

Follow up question for the group: I am likely going to forgo dryhopping in the future in favor of a whirlpool addition. I believe I get similar aromas from whirlpooling and dryhopping, but I get clearer beer from the whirlpool method.

Anyone else on a whirlpool kick? Or does the xBmt team want to tackle that one?
I whirlpool almost every beer with flavor additions, but I still dry hop some beers on occasion. I have been dry-hopping less and less, though. I haven't quite given it up on IPA's, but I may have to try it soon. I do think the character is different between the two, but the only time it really matters to me is a massively hopped beer where I want to layer both whirlpool and dry hops together.

The most practical thing to do would actually just get my base malt in bulk from local place and order incremental values of my specialty/color/roast malts from someone like Keystone.

I plan on doing 1-1.5 gallon micro batches so it doesnt make sense to have to buy Lbs. of these grains when I may only need 0.05 lbs. at a time.
I brew smaller (2.5-gallon) batches myself, and I generally get a sack of base malt that is most appropriate to the styles I'm brewing the most, and buy my specialty grains in 1-lb increments regardless of how much I need. If stored well, specialty grains will easily last 2+ years. I've ended up accumulating a bit of a library of different malts to choose from, and outside of needing a particular strain of liquid yeast I can brew most recipes on short notice.

If O2 diffused that rapidly, then I wouldn't feel like I was about to pass out every time I stick my head in my damn fermentation chamber...

I'm a new brewer who recently read the "Hops" book, it mentioned addign hops post boil vs dry hopping..  I've read several articles on same.. and a thread on homebrew talk 

I did a whirlpool hop add post boil on my last IIPA which is fermenting now, the Aroma is heavenly, hope it lasts....
I find that whirlpool hops last way longer than dry hops. Dry hops seem to fade in weeks to a month, but I've had IPA's with good hop flavor/aroma for 6 months or more when using lots of whirlpool/hop stand hops.
