I brewed a flanders at the beginning of August. I pitched Roseleare blend straight from the start with no additional yeast cultures, save for a few bottle dregs. It has been in the same carboy since. The gravity is about 1.010 and it is fairly well funky already. There is very minimal sediment in the bottom of the carboy. Loads of stuff still in suspension. No pellicle has been observed.
Do I rack it off the initial sediment to avoid autolysis or other unwanted flavors or does it need to sit just as it stands for maturing, and how long before I rack it if at all?
I’d keep it on. That’s what I’ve done with my sours with no ill effect so far. Eventually things will start to fall out of suspension and pellicle will form.
In regard to temp then, since you mention it… What do you store it at? For the first month of ferment I had it in my fermentation chamber at about 66F. I pulled it after that to make room for the next brew. It got as high as 77F for a short time. The ambient temp. is now down to the mid 60’s again where it is.
I am increasing my fermentation chamber capacity so, what temp. do you recommend maintaining?
in my experience,
warmer temps (70+) = quicker sour. not as complex and has the potential to get harsh alcohol flavors
cooler temps(mid 60s) = longer time frame to get the sour, but it is a more refined sour if you will. more complex and smooth
cold temps(50s on down) = looong time frame with a rather subdued sour. most refined and smooth though.
That being said, I don’t leave my sours in a set temperature environment (gotta optimize your use of space). I have them in my basement where the temp varies throughout the year (as low as 60 and as high as 72). I leave my temp-controlled environments open for more fickle brews.
I wouldn’t worry about the temperature swing that your’s has had. It’s way more than likely there was no harm done.
I agree, it’s probably fine. Mine go into the crawl space, where the temp never gets above 65F and never below 40F. Probably not ideal to have those kind of temperature swings, but I don’t have another place to put them that’s any better.
I forgot one variable. I have 2 oz. of medium toast French oak soaking in some Cabernet right now. I suppose if I add them I will eventually have to rack over to a new vessel so it does not get too oaky right? I soaked them for a week starting at the same time as the beer. I then dumped the wine and added some fresh wine. They have been sitting like that since in a sealed mason jar.
That seems like a plan, except, do you think I will be able to get the bag out through the carboys neck? I imagine it getting jammed in there. Also, how to retrieve it?
I would use only about 1/2 oz, and let it sit in there for a long time. You’re not likely to over oak it that way, and the beer can sit on the bugs for a long time before you rack it. And yeah, I think you’ll need to take the beer off the oak since it’s in a carboy.
There’s lots of choices for what you can do, I think you’ll just need to decide
I have racked after 3-4 weeks and then into a secondary. Turned out fine. I also have not racked at all and let the beer sit for 1 year…also fine. So take your pick!
For oak, I have added 1 oz of oak cubes for the whole year and not had a problem. I just floated them without a bag. More than an ounce may require earlier removal.
Jeff Sparows says in Wild Brews that geuzes should be left on the yeast to get that rubbery autholysis bite, but that Flanders red should lack that taste and smell. So I racked my red after primary and after two months in secondary. Now I let it sit for at least a year, maybe more.
