DO NOT add crushed grains. Use uncrushed grains for sour mash.

I have my first sour mash in the fermenter right now. I used crushed grain to add the lacto since I had some laying around. Why is it you should not use crushed grain?
 
I have read crushed grains will add a grainy-ness to the finished beer that uncrushed grains do not
 
4 days at 110F - Creamed corn, hot garbage smells. Insanely sour. Think of the warhead candy. Too sour.

1/2 of batch 4 days at 110F blended with 1/2 non-sour - Puckeringly tart, sour, but pleasant.

5-7 days at room temp with saran wrap over it and airlock on bucket - minimal smell, some creamed corn, lightly sour, mellow even. Sourness took a back seat.

As a data point... mine is finished now. I used 10% Acidulated Malt (as I've mentioned) and had it at an average of 93°F for exactly 4 days. I'd say I'm at that puckeringly tart, sour level (I do love sours). I used a handful of very random base grains (took it out of a bunch of bags: pils, MO, rye, wheat) in a paint strainer bag. I have no idea whether the amount of grain makes a big difference (I did not measure).

See below

I read that the crushed grains can leave unconverted starch behind which can cause haze

That's exactly why you don't use crushed grains. You only want the little baddies on the exterior of the grain husk (i.e. Lacto) and you already have the necessary wort made up from your traditional mash.
 
I used uncrushed grain for my sour mashed berliner and it was still amazingly cloudy from the first pint to the last. I don't think haze is necessarily a problem in this style and is actually common. Though, 2 of the commercial versions I've had were clear. Though I don't know if there are other adverse effects of unconverted starches in the final product.
 
mine is def hazy from the wheat

You may have mentioned it, but I'm not going searching. Did you get ant foul smell from the souring wort? What measures did you take to reduce it. I'm asking to see if the acidulated malt kept it in check.
 
When doing a sour wort / sour mash and tasting until you get the desired level of sourness has anyone found that after the boil and fermentation the sourness level changes at all (up or down) or does it stay constant?

I did nothing to stop smell. I got plenty of the creamed corn smell, but nothing overly foul.

Mine was kept in the brew kettle w/ a paint strainer bag with grain in it (uncrushed). Only the brew kettle lid was over the kettle (I covered the small hole in the lid - a bayou 9 gallon stainless pot w/ lid). This was in my fermentation chamber w/ a paint can heater (60 W bulb, I think) that kept it as hot as it would go (set to 100°F, but it hit 95° during the day, and closer to 90° at night).

For all that my chamber is pretty well sealed up, my extra bathroom isn't the cleanest place in the world (mold, etc grows easily). I don't use the bathroom for any bodily functions ;) (aside from breathing, I suppose)
 
I made a 5a sour mashing the whole thing at 110 for around 42 hours, then doing a 15 minute boil then pitched Safale US-05 yeast (washed yeast from a Coriander wit beer) and after 2 days is still bubbling along happily. This was a 3 gallon 5lb grain bill batch that sat in a full pot covered with Glad Cling Wrap. I also added 6oz unmilled acidulated malt and 2 oz 2 row into the mash. The pot of mash sat inside my 60 quart kettle with a 36" car battery warmer sleeve around the base of the mash pot which kept the whole mash at a nice even 110 the whole time. Had little odour after 48 hours but had a nice tart twang of taste to it.
 
Currently waiting for my homemade lacto starter to do its thing prior to a 2a brew.

As previously noted, I am trying to replicate the kumquat BW I had at cigar city.

I have 2 lbs of kumquats...I was thinking about adding half at fllameout and then half after active fermentation dies down(frozen and thawed).

Any opinions? Should I just add it all post ferm?

2 lb of kumquat for 5 gallons? I haven't had the CCB beer but if it has a big fruit flavor you're going to need a lot more then 2 lbs for 5 gallons. I think the common addition rate is 1lb/gallon but I've found that isn't even enough.

As far as adding, I'd add them all post fermentation, I don't think you're going to get too much at flameout.
 
I started souring 2 gallons wort with a handful of grain at room temp (~72F) 8 days ago and it's finally sour enough to boil and start fermenting today. Just another anecdote.

The CCB has tons of kumquat flavor. This once cheap beer keeps getting more expensive.

Have you specifically used kumquats? There is some variance within the 1 lb per gallon dosage rate between fruits based on the assertiveness of the fruit in question, right?

Yeah there's definitely a difference on fruits, which is why you'll hear people say not to use peaches or to use raspberries. I haven't used kumquats but just from my fruiting experience, I've always found more is better.

And yeah, I'm right there with you, fruiting beer gets $$$$$ quickly.
 
Thanks for the advice. Besides being tough to find, I'm paying 8 bucks a pound...Looks as though this is going to be one of my most expensive batches to date. I'll try 5 lbs and report the results. I would hate to spend 20 bucks on fruit and not get any flavor.
 
Bottled my 1030og lacto/brett splitted fermentation BW, primmed with honey. Not as acidic as expected, and still have this phenolic smell from the brett that I had in the starter, I thought it would go away...

Next time I'll try with a clean sacch strain or maybe a german weizen strain.

In this case, more is not better. I think you will find 1 lb is probably more than you need. Once it is in there you can't pull that flavor out, but you can add more later (taste it after a week or 2 and then add more).

A lot of the flavor in kumquats comes from the oils in the skins. Similar to oranges.

I added some to 1 gallon of a Lambic and it is probably too much. My wife had bought a small pack. Probably 6 ozs, it was the same size as a small pack of raspberries. I used what was left over after a couple of weeks in the beer; probably closer to 3 ozs in the gallon.

Chop them up and soak them in vodka for a week and add the fruit with the vodka. The higher alcohol of the vodka will better extract the oils and will also sanitize the fruit.

Didnt save the link, but I found a citrus grower selling 20lb boxes for 28$ shipped, maybe it was only 10lbs, either way it's a great deal if they till have them.

Kumquats are used just like orange peel, use them whole & toss them in @ the end of the boil or in the secondary. I'd do both just like your thinking, but I'm not sure about the amount? I would compare it to orange peel by surface area so 3-4 = 1 orange? Guessing here, I would start with about 9 kumquats in the boil & taste before adding more in the secondary. Might have to try this, Let me know how it turns out.

Ok, great. I had read up about fruiting and was looking at kumquats as an entirely different animal to berries and stone fruit. Glad to know I was right. So you are saying 3 oz per gallon gave a strong kumquat flavor, with the chopped and soaked in vodka treatment?
 
Has anyone seen fermentation just from the lacto culture off the grains? I had soured for 8 days at room temp and after a quick 10 minute boil I took my gravity reading and it read 1.013!! It should have been 1.039!

Many species of lactobacillus is generally homofermentative and will produce lactic acid and very little else. More likely you have a super sour beer with very little alcohol.

So you're saying it was converting sugars into lactic acid and not ethanol?
 
True, but I haven't seen this extreme of a drop in gravity in my 4-5 times I've soured my wort. I'm going to have a 1% beer at this point.

Sounds like a personal problem. Sorry, had to do it. :D

Well just add some honey and resweeten it for sacch fermentation.
 
I understand certain gravities to stay within the style, but Im not one to always color within the lines. So making a higher gravity sour in the 5a way to account for the lacto using some of the sugars as stated above does this still work well?
 
Did my first BW 2 weeks ago. Sour mashed for 72 hours @ ~100*F with a Wyeast Lacto D packet. Smelled like I expected... putrid...

15min boil and enough Tennanger hops to hit 4 IBU. OG = 1.032

Pitched a 1.5L starter of Brett. L. and has been bubbling away since.

Any thoughts on how long this will take to ferment and be ready to bottle? Im fairly inexperienced with 100% brett fermented beer.

Heterofermenative Lactobacillus will produce lactic acid, ethanol, and CO2. If you had an airlock on there and it was going, you have ethanol. How much??????? a guess would be about half of what you would get with regular yeast.
 
Love this thread!


I just did 5a extract. Sour wort/mash inoculated with .5lbs 2row and pale for 48 hours. 15 min boil/hop. Wyeast 1007.


3lb pale, 2lb wheat, 1lb pils.

Racked 1 gallon on to 2 cups pasteurized mixed berries just for fun. Might blend when finished or just bottle separately.

I'm planning on doing a '3' this weekend with the following approach:
-10 gallon batch with 1oz Citra using mash hopping
-15 minute no-boil (get the temp in the 180-200 F range)
-rack into two 5-gallon carboys
-ferment 5 gallons with WLP644 Brettanomyces bruxellensis Trois @ 82F
-ferment 5 gallons with WLP677 Lactobacillus Bacteria @ 82F
-after a couple months then combine and enjoy
 
Well ****....I think I know the answer to this but I'll ask anyways.

Last night on my homemade lacto starter I noticed a spot of green mold developing amidst the delicious looking white pellicle. Does this mean I should start over?
 
Well my first batch of Berliner was a drain pour. I did a 5a sour mashed version with wheat, pilsner, and acidulated malt. I mashed in a 10 gallon cooler, cooled to 110, stirred in a couple handfuls unmilled pilsner grain, mash covered with plastic wrap, flushed with CO2, and held for close to 48 hours. Fermented at 66 with US-05. It started at 1.032 and finished at 1.007.

It had a light odor in the mashtun but nothing serious. The aroma actually got stronger after a 15 minute boil, and worse still after fermentation with US-05. The taste is actually not bad but the aroma is so off putting there is no point in drinking it.

I had three other home brewed Berliners in the last couple weeks to compare to mine. Another Sour Mash with a near identical process to mine that turned out very cloudy, almost milky, slightly sour, and a little to sweet (finished at 1.012). It did not have a bad aroma but it seemed to lack any good aroma as well. It was just sort of blahh.

The other two were both normal mash, short boil, lacto fermented beers. One was lacto culture first and finished with ale yeast. The other was fermented with the mixed White Labs Berliner blend WLP630. Both were clearer, lighter in body, dryer, and crisper that the sour mashed version but they were both less tart/sour. One was a shorter fermentation so they may not have given the lacto enough time. The one with the blend was aged for a few months but it may have benefited from a warmer fermentation where lacto would have performed stronger.

Despite my drain poor first attempt there was enough positive going on in the beer that I am still ready to try again. I ordered some more malt and a vial of the WLP630. I also acquired a lacto culture from one of the brewers of the other beers I sampled.

I will be doing a 10 gallon batch mash at 148 for 1 hour, 15 to 30 minute boil to hit volume and gravity, split into two carboys, One is getting a WLP630 starter and I will let it got for at least a month or so. The other is going to get a straight lacto culture for about a week or two then it will get a Brett Trois WLP644 starter to finish.

What was the odor like?
