All Grain Brewing / Re: Tell me about Kolsch please
« on: June 28, 2011, 12:28:40 PM »
I've heard some people add a very small late addition or flameout addition, like 10-20g / 5gal. Any opinions on late hop addition, or just go with a bittering addition? I was also planning on a mix of Rahr pils and Colorado pale malt, but should I just go all pils?

Al Haunold ran the OSU hop development program (or something like that) in the 80s and 90s. He released all four of the Hallertau Mf mimics: Ultra, Liberty, Crystal, and Mt. Hood. He liked Mt. Hood the best, fwiw. Ultra seems harder to find than the others, but Crystal and Mt. Hood shouldn't be too hard to find.

Vanguard is another good noble-ish hop, as hopfen pointed out.

Yeast and Fermentation / Re: UNDERPITCHING, Could it be desirable
« on: June 25, 2011, 06:34:30 AM »
Underpitching may or may not be a way of developing flavors.  There are conflicting opinions and no hard evidence that I'm aware of.
One of the talks I went to at NHC said that basically there is strain dependency in this, so one strain may develop more yeast character when underpitched, and another when overpitched.  Sounds like testing and personal experience are the way to go.

"Standard" pitching rates seem like such a WAG to me that there's no way they're the "best" pitching rate for every yeast and every style. Wyeast says <1.060 and you need 6m cells/ml, while over 1.061 you need 12m/ml. If you go by the (0.75m)x(degrees plato)x(ml), then a 1.061 beer would need 11.25m/ml. I doubt Wyeast would publish that pitching rate for their products if it didn't give acceptable results most of the time for most brewers.

A lot of people talk about "overpitching" and "underpitching" and some people claim success and others failure with either. I suspect there are a dozen reasons for the differing outcomes, like the brewer's fermentation controls, yeast health, oxygenation levels, brew process, etc. I'd say any amount of yeast you pitch to get the flavors you want is the "correct" amount to pitch, and any rule-of-thumb on pitching rates is just that, a rule-of-thumb.

IIRC it took like 6 weeks for the kraeusen to fall the last time I used 2565. I didn't cold crash it, but it did linger around for a long time.

All Grain Brewing / Re: Sugar to lighten body
« on: June 06, 2011, 06:56:45 AM »
The OP is concerned that mashing higher than intended means he'll have more a "thicker" body. On one of those brewstrong interviews with Charlie Bamforth, they talk about how it really takes a ton of dextrin, all other things being equal, to increase the "body" of the beer. So mashing a bit hotter than you wanted, by itself, will have a small-to-negligible effect on the "thickness" of your beer.

From that, and my experience, I'd say the difference between actual attenuation and potential attenuation has a bigger effect on the perceived body than any of the absolute numbers. I've had a Belgian pale ferment down to 1.010 and a Saison ferment to 1.004, with almost the same OG. The pale seemed drier and thinner than the saison.

Doing a forced ferment test gives you a number to "shoot" for. You can still mess it up, like when I overshot my pale, and undershot my saison, but at least you're not flying blind.

So back to the OP's concerns, here's what I'd do. Pull off some wort and do a forced ferment test. See how your wort ferments out as-is. If you're off your mark, rouse and warm the yeast until you get the FG where you want it to be.

The dude didn't post a follow-up, but the taste test was interesting. I probably would've used a more neutral spirit like vodka.

Is there any chance the estimated pH on the mash acidification sheet could include hundredths too?  The reason I ask is because when adding salts in g/gal on the water adjustment sheet, there can be quite a significant rate range between a pH of, say, 5.3 and 5.4 on the mash acidification sheet (forgive me if I'm not articulating this well).  E.g., for one of my recipes, adding Ca(OH)2 at a rate of .15 g/gal will yield an estimated pH of 5.3.  But to hit an estimated pH of 5.4, Bru'n Water tells me to more than double that addition rate.  It would be helpful to be able to see just how various rate points in between affect the estimated pH.

I think the issue is the significant digits (maybe I'm wrong). If the calculation formula is based on one decimal place, you can't accurately estimate to two decimals. The formula, as is, is making a guess. It's a pretty good guess, from my experience, but still just a guess. The spreadsheet is like a map, you still have to use your experience to drive to your destination. It won't drive the car for you.

Yeast and Fermentation / Re: Harvesting wild yeast (but NOT brett!)

Here's what I've done: Carefully and as sanitary as possible, skin a peach and quarter the skin. I guess this could work with individual grapes, too, if you don't have peaches. I made a starter solution of about 1.020 gravity. Put each piece of skin into 3/4 of a quart of starter (that's about 700ml).

After a few days, some of the starters will turn green/gray and smell awful. Some of them will stay wort colored and smell like beer. Step up the beer-scented starters to 1l and 1.040. If it's still good after that starter is done fermenting, you can pitch into your beer.

The yeast flocc'ed in big pea-sized chunks. It was a strong fermenter, faster than average for the commercial strains I've used. It flocc'ed out better than average too. I made a wit with it, but was disappointed in the flavor. I was expecting the phenols/esters to be over the top, but it was actually pretty neutral. Mildly fruity but not nearly as phenolic as most Belgian strains. A bit of higher alcohols, but I fermented pretty warm, around 75*. Overall a good flavor, but nothing special.

I did have a few bottles I kept for a long time, and after about 6-7 months in the bottle, I noticed a very low-level acetobacter infection in some of the bottles. It could just have been my sanitation, but it may also have been on the peach skins in the first place.

Trust your nose and gut at every step. It won't behave exactly like commercial yeast, but if at any step it looks or smells "bad" toss it out and start over.

I seldom get as many esters on the second pitch of a weizen yeast. Maybe I pitch too much? I have a hefe wiess ready to bottle with WLP300 now. I'm thinking of a roggen next.

I've heard a lot of people say that. I've seldom save and repitch yeast because I like trying out new ones, but I've also had easy access to a couple different LHBSs so getting yeast wasn't an issue.

I've been reading up on the ProBrewer forums, and a lot of guys over there are pitching about 60% the amount of yeast they normally would when repitching, in order to keep the esters high.

When starting a business a lot of people will give you a lot of reasons why it won't work.  When it does work it can be very satisfying.  There's nothing like it.  Just do a lot of research and planning before you decide to commit yourself to the business.  

Two words:  Due diligence.

This is great advice. There are a million reasons not to start your own business, and you should really be aware of those reasons.

My mom's "retirement" plan was to buy a campground. Pretty much all of her friends told her she was crazy to sell her house, move to another state, and own a business. It's been a lot of work for her, but in a little over two years she's making about 10x as much money each year as she did at her last job. It took her about 5 years to find one that grossed enough and was cheap enough for her to afford, and in those 5 years she did a lot of research.

Another thing to think of is alternative revenue streams. I know a guy who wanted to start a coffee shop. He found an investor to help with the down payment, and they bought an old warehouse for about $1m. They gutted it and turned it into 5 different retail storefronts, and artist studios. His coffee shop is one of those retail stores, and they rent the rest of the building. Even at half capacity, the renters more than pay the mortgage. At full capacity they make a lot more than the coffee shop ever could.

If you need to lease/buy a brewery, why not buy a big building and earn some rent, if you can get the capital together for the down-payment?

Major - It's good to know that the esters don't diminish much with lower temps. I was curious to know if they could behave sort of like other "german ale" yeasts, or if they were totally their own animal. It's been a while since I've used 2565, but I remember a fair amount of fruity/winey/pear-like flavors. When I used WB-06, it reminded me of 2565, but maybe I'm totally wrong. WB-06 seemed to give a much different flavor than the 3068 I'm used to using for Hefes, A lot more apple/pear fruit flavors, and lot less banana and clove. I've heard people say the exact opposite, that their WB-06 was either a clove or banana bomb, so I don't really know. Maybe it's the ferm temps people are using?

I've read that wheat malt is high in ferulic acid, which makes 4VG and clove flavor. I've also read that WB-06 trends more toward clove than banana. Maybe without any wheat malt the WB-06 didn't make much clove or banana, and that's why I could pick up more "other" flavors.

I wonder what the results would be like if you made a Belgian style wort (Belgian Strong?) and then fermented it with Weizen yeast?  I wonder how much the flavor profile of a Weizen is directly related to the wheat?  I know the Belgian and Wheat yeasts have different types of phenols, but has anybody ever tried this?  Just curious...

As for "how much of the weizen flavor is related to the yeast" I'd say "some-to-most." My dampfbier grist wasn't much different than a Belgian Pale, it was 97% pale malt and 3% Special B for some color. I fermented it with WB-06. I don't think you could confuse it for a wheat beer, but it definitely had a lot of weizen-like yeast character. I'd say it tasted closer to my Patersbier fermented with 3787 than my Hefeweizen with 3068, but I haven't brewed back-to-back batches with the exact same yeast and different grists.

I've also heard people say WB-06 is not particularly "weizen-y" so maybe that yeast is a bad example.
