General Homebrew Discussion / Re: Pils-friendly Water chemistry
« on: October 22, 2010, 07:37:55 AM »
I mean, I can get 10 gallons of RO water....then add some of my water back to the mix, but to understand what the resulting chemistry of that mix will be is highly challenging to my understanding of what I have actually arrived at

When combining two different waters, just do a weighted average for each ion. (That isn't technically correct, but it's certainly close enough for our purposes.) If you're diluting with distilled/RO water it's really easy: just multiply each concentration by the fraction that's tap water.

So, for example, if your HCO3 is 337 and you mix the water 50-50 with RO, the resulting water will be 337*.5 ~ 168 ppm HCO3. If you use 2 parts RO, 1 part tap, it'll be 337*.333 ~ 112, etc.

Your biggest problem will probably be sulfate. For anything other than a very hoppy beer, you'll need to dilute at least 3:1 just to get that under control.

This may help, depending on where the difficulty lies: http://seanterrill.com/2009/08/08/water-water-everywhere/ It's a decent starting point, at least.

Just throwing this out there: are you kegging? It's extremely dangerous to stop fermentation in a beer that's going to be bottled.

You added a really small amount of sugar. I'm sure it's just finished. The fact that you saw active fermentation is a good sign though.

Off topic, and maybe for another thread, but I'm curious as to why everyone feels that homebrewing is not cost effective.

Just the time involved. Obviously that's a crazy way to look at any hobby, but if we're talking about a true cost-benefit analysis, you'd have to include a fair value for what your time is worth. Which is why I was saying it's unreasonable to think that about distilling, but not brewing.

Actually, even the equipment costs can be amortized fairly quickly. I've probably invested more in the equipment than most (just under $2000) and after 48 batches the equipment and ingredients are under $1 per 12 fl oz.

The thing about tech talk was that I had a daily reminder that I was a member of a national organization.  I have time to check email once or twice a day, never minded that reminder, and usually read it.

Maybe this is what you're looking for? http://www.feedmailer.net/

General Homebrew Discussion / Re: cooling my wort (new brewer)
« on: October 21, 2010, 08:00:17 AM »
The conventional wisdom is that ice is not sanitary and should not be added to wort.  But since I've never tried it, that's about all I can say.

Well, the OP was specifically asking about pre-boiled ice.

This has been a sore spot with me for a while, and it's good to see someone who shares my view.

Yes, it's good to know we all agree that brewing is a worthwhile hobby even though it isn't cost-effective. Then again, since we're all brewers, we already knew that. ;)

Also, the header of TT usually had an AHA or industry-related post by Charlie P.,  Gary Glass or some other folks.  If there are announcements like that on this forums, I think I lose them in the RSS feed.

Is that anything like this subcategory?

True. The aging requirements alone (for whiskey, anyway) are a pretty significant barrier to entry.

I was just saying that I don't think you can justify homebrewing from a cost-benefit perspective.

IMHO, adding ice is the best way to chill wort from a partial boil. Cold water works, but an equal volume of ice gives you, on average, three times as much cooling. If you make ice with 2.5 gal of water, and add it to 3 gal of boiling wort, it will stabilize at ~69°F.

Distilling, to me, isn't worth the effort.  The cost-benefit analysis of distilling vs. going out and buying your own bottle of whiskey is a clear choice.  It's cheaper, easier, and less work to buy your own, not make your own.

Isn't that true of brewing as well?

2938
If you're using malt extract (and I would assume you are as a first-time brewer) then you can probably calculate the OG more accurately than you can measure it. If your volume was close to the target, then the OG was right on, and you got a high reading because of inadequate mixing.

Kegging and Bottling / Re: CO2 vs priming sugar
« on: October 20, 2010, 02:14:36 PM »
Unless you have a way to cool the keg, you probably won't be able to get a good pour out of it anyway. Some kind of refrigeration is pretty much mandatory.

It's also possible that you'll get a keg with a lid that doesn't seat under zero pressure. In that case the CO2 would just leak out without the keg ever sealing.

Welcome to the forum! I think you'll find it meets your needs.
