Apples are allowed to soften before pressing. but IIRC, pears get too mushy for pressing if allowed to soften.

Use 4 L of frozen water in soda bottles to drop down the last 20 degrees.  This step will take a few hours.

Yeast and Fermentation / Re: Brettanomyces pellicle or infection ?
« on: September 14, 2015, 07:30:39 AM »
I've never had lacto make a pellicle (and I've soured with lacto solo before fermenting many times)

Also, the yeast strain you used is not actually Brettanomyces

I would just have a taste and see how it is...

I have gotten pellicle with lacto which looks the same as Brett pellicle, not that I would be concerned about lacto here.

Sounds like you should put a sleeping bag over the corny and cooler.

Last year I did 3 batches of sour without adjustment to 4.5 post boil. This year I did 4 batches using adjustment to 4.5 post boil. Last year's beers were not gross. This year's aren't done yet obviously but from tasting the hydrometer samples they seem a lot cleaner. So far...

At this early stage of trial I am willing to commit to saying that adjusting to 4.5 is insurance. However, its not a substitute for ridding your process of oxygen. I still purge with CO2 every transfer and every time I open a fermentor to take a sample.

That purge is what's scaring me. If we transfer the wort after mash, short boil, pH adjustment into a carboy (with an auto siphon to avoid splashing) to pitch the lacto there will may be some O2 in the carboy. Maybe we should use a smaller (3gallon) carboy to leave little headspace? Fermenting in a corny sounds ideal but I'm not brewing at home where I'd have access to the keg & C02.

Oxygen exposure during sour worting with lacto is not that harmful if you have another control on harmful bacteria such as  boiling or pH below 4.5.  Oxygen exposure causes the lacto to produce a fruity odor (ethyl acetate?).  I like to do the lacto ferment in a closed bucket to reduce oxygen exposure during fermentation but I am not concerned about oxygen exposure before pitching the lacto.  Some folks say that oxygen exposure inhibits lacto but I believe that to be overblown if you have the control on harmful bacteria.  If you very much dislike fruitiness in your sours then limit your samples as indicated by Klickitat Jim.  I don't find limiting samples to be necessary. In any case, the 2008 BJCP guidelines (have not consulted 2015) for Berliner Weiss allows for some fruitiness.   For the record, I do a starter with pilsener malt which drops the pH to 4.5 upon pitching and don't do a boil.

Calcium levels of at least 50ppm still apply?

Yes.

It's debatable. The Ca content is largely needed for two functions: precipitating oxalate from the mash and flocculating ale yeast from the finished beer. The first function is always worthwhile, but the second function isn't really needed in a cloudy wheat style such as Berliner Weisse. Calcium is not needed for bacteria or yeast health since the malt provides all the calcium necessary for that purpose.

I stand corrected.

Also is dropping the pH down to 4.5 pre inoculation even a good idea? Read it a couple places but know theres a lot of bad info out there.

Dropping the pH below 4.5 is good if you want to avoid vomit smells due to bacteria in your tun or your grain.  However, if you boil before souring then dropping the pH is probably optional.

Hmm, think the fact that it's only 3 gallons of really low gravity will help reduce the need for a starter? Or would jumping in today without one be pointless?

I'm unclear if you are referring to a lacto or yeast starter.  While a lacto starter isn't necessary since you said that you plan to drop the pH below 4.5 before pitching lacto, I like to make a lacto starter so that the starter drops the pH of the wort below 4.5.  Also I do like to make a yeast starter with the pre-soured wort because the ale yeast can use a boost due to the acidity of the beer.

The chloride level seems high for a sour to me.  What is the reasoning behind the mineral profile?

Took it from Tonsmiere's (The Mad Fermantationalist) blog post. Looks like he used a pale low hop profile. The past was from 2008 tho in case best practices changed.

http://www.themadfermentationist.com/2008/02/berliner-weiss.html

Subsequent Berliner Weiss's in the Mad Fermentationist blog appear sometimes to not have any added salts.  My recommendation is that other than adding salts to get the desired mash pH, minerals should be sparingly used to avoid salty flavors in sours unless making a Gose.

DMS is not an issue in sours so no long boil is necessary.

Where did you come up with this?
Personal experience and prevalence of 10 minute boils in making sour worted Berliner Weiss.  Do you disagree, Reverse?

Everything homoeccentricus said and asked is valid.

It looks like you are more than half way through fermentation based on estimated starting gravity and current gravity.  At this point, oxidation becomes a major concern so you should just sit this one out.    I suspect that the aging period will be quite long.
