General Homebrew Discussion / Re: Is your boil-off volume reproducible?
« on: September 21, 2011, 04:42:42 PM »
Humidity will definitely affect the boiloff rate, but I don't think it could explain a 50% variation. I brewed my first fifty-odd batches in the Midwest, so there must have been some major changes in humidity, and I never saw anything close to that kind of discrepancy.

The *minimum* velocity would be something like 50 m/s, so if it was a small one and you happened to be looking in the right direction you could probably get clear. Statistically speaking, you'd probably jump right in front of a car though. ;)

Kroger (aka City Market) store-brand club soda and tonic water still come in 1 L and 2 L bottles with the standard PET threads. I don't know if they have a store-brand ginger ale, but for $0.78 apiece you could always just dump out the club soda.

Do you have a pic of the finished product you could post?

Not that I can get to right now, but Google turned this up:

Beer Recipes / Re: Something like Peroni

I'm working from memory here, but I think that's going to be much hoppier than he wants, and I don't remember Peroni having any of that corn-like flavor from 6-row. The crystal malt wouldn't be typical for the style either. I'd go with something like 85% Pils, 15% flaked rice, and a single hop addition targeting 15-20 IBU. Just like any other macro lager.

What yeast are you going to use? That's probably going to make the biggest difference in getting you close.

The result is that for the second step it's telling me I would need 1.48L of starter for the second step to achieve 350B cells.  That's obviously not doubling the volume for the second step.  I've tried a couple of other scenarios and got similar results.  What am I doing wrong?

There is no "wrong" since we're just talking estimates anyway, but for this situation I'd go with 1.0 L, then 2.2 L. Using "intermittent shaking" for both, the calculator says that ends up around 350B cells.

Sean, it sounds like you only do single-pallet orders, is that right? Is / Ball your distributor for that as well? $400 per pallet, that's something I could afford. Do you do anything special for your labels (like wrap-around or something?) or are they just the standard 2/3 circumference sorta deal?

Sean one more thing, how heavy are those pallets of cans?

Yes, we get ours from Ball in Golden, CO. We typically get three or four pallets at a time, since that's all we have the storage space for. They're very light - two people can lift one. Probably 100-120 lb. The height makes them hard to move rather than the weight.

For labels, we use regular 3x6" stickers, printed on glossy stock with an adhesive back, and apply them by hand. There are probably a couple hundred online vendors who would do the same thing, but we use

You would need to fill your boil kettle a second time and chill the water prior to dilution.  Essentially you're using the same energy to boil just water, and you'd need to have a vessel large enough to blend the batch.  In-line dilution is impractical and you'd need an extremely expensive valve that would regulate the value aperture based on the flow rate of both the beer and the water.  Otherwise your in-line blending would be inconsistent.  These valves are electronically regulated and you'd need the flow sensors, the valve, and the electronics to run it all.

Since no one would have to be around to monitor the boil, you could set a timer to bring the water up to the boil at night when the kettle goes unused anyway (assuming you aren't running three shifts). The next day you'd have room temperature water ready to go. As far as blending, no reason you'd have to do it inline. Just keep an eye on your sight glass/volume markings/whatever during transfer or filtration, stop at the correct point, and top off with water. Maybe recirculate for a few minutes to get it mixed, if that turns out to be necessary. As someone else pointed out, you could also do it in two batches and avoid the need for a double-size bright tank.

The Sean Terrill site is pretty cool.

Thanks! I haven't been able to put nearly as much time into it lately as I'd like, but there's some good stuff in the pipeline.

By the pallet (4552 cans), we pay about $0.09 apiece, including the covers. Printed cans are actually not much more (and would be cheaper once you factor in the labor savings), but the minimum order is large for even a medium-sized micro. 12 pallets IIRC.

I do a (moderately) concentrated boil since we have a 6 bbl kettle and 7 bbl fermenters, which is fairly common. I've never tried diluting post-fermentation though. I expect that the beer would taste quite a bit different from one fermented at the target OG, especially if the gravity was doubled. Of course, if there was no baseline for comparison, like in the case of a new brewery, that wouldn't matter.

I live in eternal fear of doing something like that. We actually have a compromised stainless conical that looks similar, just sitting there as a constant reminder.

I'm certain there is a more scientific way to approach this using the calculator.

Yup. ;)

Have you checked out the FAQ?

Like tygo said, you can reduce the size of the starter by introducing oxygen, even if it's just by shaking.
