I just now had a question for George. Called him and he answered it. He's a man of his word.

I recently visited several bourbon distilleries and most mentioned sour mashing but none of them actually explained the various techniques for doing it. Thanks George.

Thanks George, another sweet tip, I'll try that ferment on the grain one, I find it easier to remove the alcohol wash from the grain... than to remove the liquid and then ferment it. Love your tips for beginners, it makes hitting the bulls eye (or there abouts)a lot easier.

I just can't say THANK YOU enough George ! Not sure I would have gotten into distilling without you Sir. I had the desire, and actually most of the knowledge, but I lacked a mentor to keep me from making BAD moonshine. Happy Distilling and Thanks Again !

Gees you never fail to teach something completely awesome in one of your episodes. Thank you.

You are the best George you Taught me how to distill years ago I remember when you had five subscribers look at you now 50,000

Been loving getting back in to your videos, George :-) Very happy to hear the comparisons to sourdough as well, that's been a life-long passion for me. One bit of advice I'd offer to anyone doing sourdough, sour mash or any of the like is learn how to make what I like to call 'doomsday vaults' for your starter. Take my sourdough, I've got a frozen portion at home as well as the active one in the fridge, a frozen portion in Mum's freezer and I feed that when I'm down (I got my love of sourdough from her). Plus I've learned how to freeze-dry started at home and had nothing but success, I've been assured that the same method works just as well using barm or backset from sour mash as well.

Out of all the other videos out there on this subject, yours are the best.

No matter how many other people distill on ytube you are my absolute first choice for good information. Im hoping you and yours are well. Thank you for your good work .

Great info George!!! 👍👍👍

Hey, George. Lotsa folks out here are missing you & your videos. Hope you make it back soon.

I heard the podcast with Jesse, Great content!

So does a sour mash have to be fermented on the grains or can the grains be sparged rinsed and then turned into a sour mash

You sir are a gentleman, salutations from an Englishman.

Hi George, Thank you for this video, really enjoyed this one. Please can you advise if method 3 (stillage leftovers) can be used on a sugar wash from gin? Note, both from the stripping run and the vapor infused gin run?? Good video and thank you for your support.

You are a legend!

Thanks George, do you have to use the same grain bill?

Love your videos. Helped me a lot and did my first run of shine yesterday.thanks. Please can you tell me the name and artist of the song in the beginning.

Right on, thanks for another great video George! So if I'm hearing you right, using all three methods would be basically a UJSSM, correct? It takes a portion of the grain, all the trub/barm and a volume of the backset. Or can a UJSSM be called a sour mash since it isn't all grain?

..hello to a fellow from "the great forum". Same question dawned on me to use all three. It never occured that was the methods to that recipe. Ive never made it, but have an itch now. Still on brotha

Thanks. As usual very useful information. I have always wondered how these things were done before commercial yeasts were available. You mention long chain fatty acids. Do these become esters? They are too high boiling to distill over, unless a small amount gets carried over with the water / ethanol. I am starting to understand more and more that getting high purity alcohol is simple science and is the easy part. Getting something that tastes good that is the artistry.

would there be a difference in taste if you used a sweet roasting ear corn verses a regular field corn?

i screwed up in the right direction...for once. i'm on my 3rd. gen sour mash. i knew about saving yeast and my used corn, from George's videos and using back set from Still It. (ujssm) i just put it all together. i love this hobby and it's not the kill, it's the hunt that makes this fun.... well somewhat the kill....lol

How long will the spent sour grains keep in the bucket before they're used for the next mash? Can they be kept longer than 3-4 days? And when are you adding them? During the mash or just before pitching your yeast?

I would take the sour dough starter and 'dissolve' in water to get the yeast going in all the water. Then add all the other ingredients to the water then add 2/3 of the flour and mix. Then add 1/4 cup of flour at a time until the dough is mildly sticky. (you may not add all the flour called for, the dough presentation is what is important). I couldn't help myself, I've been baking for a month and I am an expert ;).

I have a question for you George. If I decide to use the backset as a sour mash how long would you recommend storing that for and what would be a proper way to store it? Thank you.

Taking stillage/backset and putting that into the next ferment is also an industry standard for sour mash. That's second generation though. Since stillage/backset is typically low pH already, because the ferment it came from had been infected with lactobacillus. This also saves on water and helps keep flavour profiles similar between batches. They may use between 33% and 40% stillage when doing this. Another method is to mash as normal, then drop the temp to around 40C, and intentionally add lactobacillus starter to the mash, to cause the souring.

@davidprice7546

4 жыл бұрын

What temperature do you ferment at that you would drop it to 40C (104F)? I am curious if I can add some lactobacillius from a probiotic to my mash days prior to pitching yeast to obtain a sour mash. My experience is only in beer and wine, so until I started messing with kviek, I would always ferment around 20-24C (68-75F). With kviek, I'm fermenting at 27-34C(80-94F).

Where do you store your barm between distillings? Refrigerate? Does it get better with age or have a shelf life?

How does column vs straight to condenser pot still equate. Would column still be like running 2 strips in a pot still or are they the same cause they your not running the cold water jacket? Jw if the column with packing strips more flavor than kettle to condenser pot still. I want cleaner flavors. Not vodka.

very informative

🙌🏻 mash time!!

Thanks George!

Hey George been following the videos and have learned so much but im still not understanding how the old timers could use corn,malted corn,and sugar only no yeast in the wash. How is this possible without pitching yeast? Please do a video on the old time recipes if you havent already thank you so much!

Great info! Question; when using what’s left in the still, do you put the material in the mash container to ferment with the new grain or keep aside to add in the still when the your mash is ready (separately)?

@TravisQuiring

3 жыл бұрын

This is my question too after watching this video, anyone have an answer?

Question. Can i mash in new grains on the left over mash right after the run? The left over liquid is still hot enough to steep the grain and then will cool down to the 155 degrees for the amylase enzyme to be added. Or does it have to sit for a few days in order to rerun it? Is it also ok to use more than the 25% of the left over after a run?

For our sour mash we would take 25% of the backset and put it in the fermenter with the new batch instead of saving it and adding it directly to the still later. It lowers the PH and yeast love it. In fact we would take it from the still when the temp was still around 155F (after they were turned off and cooled a bit) and put it directly in the fermenter to keep the temp in there above the 143F to allow the amylase to have further time to convert before pitching DADY. Not sure if this could be a #4 type sour mash for George.

Lactic Acid does not cause fermentation but is the product of the secondary fermentation carried out by various sp. of Lactobacillus bacteria.

Where in the CFR 27 does it state that sour mash needs to be at least 25% of stillage? It is a ph adjustment to about 4.5 to 5 and is usually 2 parts (combination or method 1 and 3 you mention). Put some fermenting liquid from past batch into next and during cooking add some stillage to the water to cook. I sometimes also use method 2 to transfer yeast.

Thank you for your videos! The science behind all this fascinates me. Quick question using the 3rd method from this video; do you just continue to use 25% over and over, from one batch to the next, or is it make one batch, then one batch of sour, then start fresh? Thanks again!

I've never done a sour mash but I want to try one. If you don't mind I have a couple questions. Let me know if I have this correct: at least 25% of the sour mash was made from mash from a previous run? Like if it was an 100 gallon batch of sour mash 25 gallons would be from the last batch?? Also, how many generations can you do sour mash? Will it get nasty after several generations? Thank you

Which method does Jim Beam use? 1,2 or 3?

What if you use Malolactic bacteria in your fermented mash and do a second fermentation? The lactic acid would produce the same flavor?

Since you are adding 3lbs of old mash into a new batch, do you also need to add more water?

I was under the impression that barm was the yeast that floated to the top of an ale. Either way, that is why eastern and central Europe have more sourdough breads than western Europe. It is much harder to extract yeast for baking from lager than from ale.

Love the videos George. I have one question though....Where can I find that song in the beginning? I've been searching and can't find it anywhere.

#4 (pulled from my brewers hat) you can just add in off the shelf souring bugs to the ferment, yogurt, bleu cheese, buttermilk, or a shot of lacto from you LHBS :) . Let the yeast start and take hold, after a day or 2 of active fermentation introduce the bugs.

Would it matter if it was added after or before pitching yeast, like in a kettle sour?

The concern I have with adding three pounds of the last batch to the new batch is how to convert the new grain bill so that you don't have to much solids in your 6 gallon fermenter, it seems it would reduce the amount of liquid you would have to put into the still because you don't have as much room to add water. I imagine you would only have about 3 gallons of liquid to run with all the new grain and then three pounds of the last mash?

copper is there as a filter for hydrogen sulfide that is produced from berries and the like. The stainless won't do that.

So is it bad to let my mash clear before distilling? I have only been using clarified (looks crystal clear almost) mash that I treat the same as if I were making beer or wine except I don't filter it.
