Going Pro / Re: Filtering levels and methods
« on: December 21, 2011, 02:11:21 PM »
I have never heard anything positive about the canister filters. Plate filters can be a PITA. I have totally eschewed filtering. I have single walled bright tanks that are held around 36-38 degrees. I use a product called Biofine Clear A3 (it's vegan, if that means anything to you) and add it to the bright tanks after a yeast dump.

I'll second all of this advice. I used the Biofine in the fermenter after cold-crashing and dumping yeast and that also works very very well. I didn't have standpipes in the bright tanks, so dropping sediment in the brights would have been a Bad Thing.

FWIW I don't think I've ever seen 12 ppm referenced as an upper limit. And I know I've read several independent sources that recommend ~15 ppm for high-gravity beers.

OTOH, saturation of pure O2 in water is ~50 ppm even at ale pitching temperatures (~60 ppm for lagers). I would have no trouble believing that could be detrimental.

Anyway... Maybe I can take a look at equipment tonight.

Or maybe wait and let the girlfriend help out with your equipment in the morning? ;)

No can do, man. Pick up a six pack and spend some time with your girlfriend.

Growlers are also marketed by many as a green alternative to disposable bottles, but forcing them to buy a new one is counter to that. And many customers do want, do not have the space, or do not want to spend the money on more growlers and you'll loose those sales.

Well, I'm not talking about forcing anyone to buy anything. I'm talking about refilling their growler *and* giving them a free sticker. ;D

General Homebrew Discussion / Re: BB Sanitized. Time Limit?

I agree with you, but I can store StarSan in a growler for months and it's fine. I do that with Iodophor and I get something that at least looks like mold.

Is it sealed? Once diluted, the iodine in an iodophor is able to sublimate, reducing its effectiveness pretty quickly. That would also apply to a relatively small amount of an iodophor in a sealed container with a lot of headspace.

When in doubt, a quick visual check should tell you what's what. If the solution is no longer yellow-orange, the free iodine content is too low to be effective.

I store iodophors in an airtight container for months, reusing them until they pick up particulates or lose their color. No problems yet, touch wood.

I would *think* it's still sanitary, but I would sanitize it again anyway. For me, there's a lot of benefit for very little work.

This works well with StarSan, but don't do this with Iodophor, unless it's just for a week or so. The stuff will grow mold after a while.

If you have mold in the fermenter, how sanitary was it to begin with? I know that we can't exactly work in a clean room, but that would scare the hell out of me.

I've done it both ways. The potential problem with carbonating using a PRV on the fermenter is that, like Keith said, you really have to be hitting your FGs dead on. The ~30 psi of head pressure is really tough on the yeast, and if you cap the fermenter too early they could flocculate prematurely.

Good one Ron.  Perhaps you prefer our rainforests? :)

Is that real?! It looks like something from Star Wars.

Yeast and Fermentation / Re: I am new to lager

Gordon Biersch does.

At all their locations, or is it at the brewer's discretion? Do you know what kind of equipment they have that allows them to do it? Filter after the heat exchanger, or maybe just a settling tank?

Ambient air is only 21% oxygen (78% nitrogen).  Bottled oxygen and an airstone are way more efficient.

True, but how much efficiency does a home brewer really need? Pumping oxygen instead of air saves 10 min, but it also costs more.

To date, though, there is no alternative non-BPA can lining that works for anything acidic.  Beer is acidic.

You can get BPA-free cans, but they're pricey. There's a thread about them over at ProBrewer.

Personally, I don't think you should be giving beer to pregnant women or infants in the first place.

The starter was still after almost a day at room temp (around 70), so I figured the yeast was bad.

If you had nice fresh yeast, the starter could have finished out in less than a day.

We're *finally* getting some more snow. About 12-16" out of this storm, and it's our first significant one in over a month. The next few days look to be sunny with a couple feet of fresh powder. 8)
