Hey all. I live near Boston, so we have a banging Chinatown. I went there to try and find some Koji rice or Koji-kin... I was going to make Sake. Here's where my adventure begins...
Wandering through aisle after aisle of things, no English, even the workers can't understand you...
But you know it's here... somewhere...
Eventually, I was able to find an extremely old dude and his English speaking daughter.
He gave me this recipe. I never did get my Koji rice or Koji-kin.... but I did get this crazy recipe. And I discovered Chinese Red Yeast Rice, aka Beni Koji... Red Koji.
.
Anyways, the old Chinese guy told me to do this:
For 2 Gallons Akaisake
Take 7 lbs short grain white rice.
Rinse it until the rinse water runs clear. Work it with your hands, stir, rinse.
After, put it into your bucket. Add enough water to cover it, with about 2 inches above the rice.
Soak for two hours.
Drain, rinse well again.
Wrap the rice up in a clean white cotton towel, or a cheesecloth, or a tshirt. Steam the rice, the water can't touch the rice... use a colander inside a pot or whatever you have to work it out. If you can't swing it, just make the damn rice however you want. Make sure to rinse and soak it as best you can. Steaming makes the best booze, but you can still do it however.
Put the drained rice into your sterilized bucket.
Add Distilled Water, 2 gallons... add slowly, take the temp... when you get it to 100 F, add 1 lb red yeast rice and 1 packet yeast.
Mix well.
Cap it and airlock it.
Let ferment for 2 weeks
Strain out the solids, and rack it into glass bottles. You could drink this right now if you want, it will be cloudy, but good. Chilled is best. If you plan on stopping here, make sure you keep it chilled, it can go bad if you don't.
If you want to continue on....
Set aside somewhere cool (65ish) for another two weeks. Secondary Fermentation is occurring, so leave some way for gas to get out... glass carboys with airlocks are ideal, but a non lubed rubber with a pinhole does the trick... use what you have.
Strain off of the remaining sediment, bottle, pasteurize. Boil it in a water bath until the liquid reaches about 140F, then cap it and it's done.
Drink or Age.
Don't drink it warm... that's for the crappy stuff, not this.
You will have a red wine finished product.
If you want, run through a still and make Schochu. Or keep it this way and enjoy!

# Frequently asked questions:

1 - Slick, seriously, WTF?
Well, I'm glad you asked that!
Apparently, the mold used in traditional Japanese Sake, for Koji rice or Koji-kin, is Aspergillus Oryzae. This mold acts on the starches of the rice, and produces an amylase enzyme (Hah! You've heard of amylase before!) Anyways, the mold produces the amylase, converting the rice starches to sugar. The yeast produces ethanol from the converted sugars.
***************************
Enter...Evil Merck! - Apparently, the Koji mold having been in use for thousands of years, was still somehow able to be patented by Merck Pharmaceuticals.
Wait, What?
I know, Right?
But it's true. They bribed the government and got a patent on Aspergillus Oryzae, a naturally occurring mold.
But why would they do that?
Well, Koji kin produces a statin that boosts your good cholesterol, and lowers your bad cholesterol.
Wallah... Levitra! Huge moneymaker. (EDIT - Levitra makes your wood go wood, it's actually lovostatin. Doh!)
So naturally, Merck is out to stomp on red yeast rice, aka beni-koji.
Fortunately for us all, Chinese shopkeepers pay no attention to such nonsense.
*****************************************
But Slick, Beni-Koji doesn't contain Aspergillus Oryzae... why does Merck hate it so much???
.
You're absolutely right! Beni-Koji is inoculated with an entirely different mold, monascus purpureas. This is where the red color comes from. Monascus purpureas does the same thing aspergillus oryzae does... it produces an amylase enzyme that converts the rice starches to sugar. The yeast then converts the sugars into sweet sweet booze. This sends the yeast and the mold into a crazy feedback loop where they go into a symbiosis and start cranking out the ethanol... this symbiosis allows the yeast to continue to function in alcohol levels that would normally kill them...it's normal to get 15-20% out of Bakers Yeast!

****************************************8
.
But Slick, you still haven't told us why Merck hates Beni-Koji so much!
.
Well, as it turns out, monascus purpureas produces the exact same statin as aspergillus oryzae does. Identical down to the atomic and molecular structure. That means you can buy 300$ worth of Levitra for 4$ at any Chinese Grocery! Google takes loot to suppress this.
***********************************************
Anyways, don't worry about the details... follow the instructions for a sweet delicious red wine made from white rice. And it will lower your cholesterol.
What's not to love?
*********
Edit to say, this my first time, so I'm not going to be sure it worked until it finishes. Also, maybe the cholesterol drug is a different Merck one, not sure, but the statin info is solid.

*************************************************************
EDIT 6/20/13 - I have done several batches now, that recipe works, but is not ideal....
Here is "The best method in my opinion"* See SonOfGroks thread in my sig, or read this whole thread. Many Mighty Seekers Of Truth And Ethanol have contributed Mightily. I thank Them All.
No Added Water, Distilled or otherwise. The Ancient Chinese Dude even said to add water, but my experience has been that it makes it less sweet and more dry to add water. I have also found that Booze Levels stay pretty much the same... a 1.5% increase in ethanol isn't worth the difference in taste, again, that's just my opinion.
Steam the rice or just cook it, it doesn't seem to matter that much. Buy the shortest grain rice available, that's important, shorter carb chains. Let it cool, make sure there are no spots above 100f.
7 lbs dry rice before cooking
2 pounds Red Yeast Rice
113.5 grams chinese yeast balls, crushed. {Put them in a bag and smack them with the round side of a ladle or spoon.)
Cooked rice should be around three gallons by volume in the bucket.
Pitch the Red Yeast Rice and Yeast Balls crushed just like yeast, in a big bowl, warm water (80-90F) let it soak about ten minutes, then add it in and stir. Or just mix it in dry by hand. Whatever.
Cap, airlock, wait three weeks, 21 days. No need to open or stir. You should get around 13% ethanol, waiting longer results in a dryer, more alcoholic and less sweet wine with higher content, about 16% max.
Open, strain, drain, will be cloudy, filter or let settle and rack, or both.
The solids can be used again with fresh rice.
The liquids will continue to ferment and will be cloudy, beware bottle bombs. Cold crashing will not completely eliminate this. Pastuerize at about 160f for a few minutes and it should stop. Don't heat to 174 or alcohol will be lost!
You can drink it "raw", unpastuerized, it's cloudy and fresh and delicous. You can bottle it pastuerize it and age it. Whatever you want. Leave some in a small bottle open to the air and it will turn to red rice wine vinegar, great for cooking.
These are my thoughts, there has been Tremendous creativity in the other thread in my sig, it's a long read but well worth it, and interesting as hell.
Special Mention to LeadGolem and SonOfGrok and EVERYBODY in this thread and the rice wine thread.
All the Best.
 
I like not having to open my bucket with all the steps, like traditional sake making. Less chance for anything bad to get in, and it's less work. I suppose you could do all that stuff if you want to. That Sake guy Taylor did all the steps but he mixed Beni-Koji with.. I think it was yellow koji. It's one of the few sites that come up if you search for Beni-Koji.
 
I have a picture of the red yeast rice and a boring one of me steaming rice in a t shirt... not me, the rice. From what I've red, there isn't actually any yeast in red yeast rice, just the mold. Chinese medicine shops also sell "wine cake", but since nobody can explain what's in it, I'm going to hold off on that. Plus, that old guy recommended this, and he seemed pretty knowledgeable.

Day 5, all the liquid has been absorbed into the rice. I was told to expect this... the rice sucks up all the liquid then liquifys... hopefully.
 
Another day, not much change. This is the rice. I'm using but any short grain rice should do... don't use brown rice, the husks make it harder for the mold to penetrate.

Subbed. Definitely looking forward to the updates. The rice you used looks very much like the Japanese sweet rice I used in my 6 grain experiment.
 
If it doesn't taste good after secondary fermentation I'm going to run it thru Lyssa to salvage the booze, but I feel pretty confident... I was told the rice would suck up all the liquids then Liquefy, but for the first week I was kinda scared... once it sucked up all the water I felt a lot better about it (especially after reading that people with too much water in the rice wine thread went sour!). Once I get a lot of liquid again I'll feel much much better. The airlock keeps bubbling, so that's good. Day 8.
Hey Lead Golem.... Red Corn Whiskey??? Just a thought... this weekend I'm going to put down a bucket, see what happens.....
I don't plan on ever buying any commercial amylase ever ever again. Not that I used much anyways, but if it's free in Nature why pay?
Waaaahhhh!!!!
 
Definitely looking to see how this turns out.

You did have me confused there for a minute - Levitra is an erectile dysfunction drug...I think the Merck drug you're looking for is Mevacor (lovastatin), although it would be hilarious if this stuff turned out to be erection enhancing.
 
I imagine with the corn, you'll need to crack it first.. correct? Years ago, I was wanting to make a still and was reading up on how to make the mash, and it talked of wetting the corn, letting it sprout, which somehow converts all the starches to sugar, then cooking it, beating it in a sack to knock loose all the sprouts, sifting those sprouts off, etc... Seemed like a lot of trouble.

I don't know about making a wine from corn, but it seemed to me that if you cracked some corn and added some RYR and yeast to the corn, it'd convert that to run very well through a hypothetical still, since nobody actually has those since they're illegal.. But starting with a mash that was already in the 18-20% alcohol range would yield quite a bit of booze... hypothetically speaking.
 
Well corn is a starch as well, and it needs a little help converting. That's why the procedure you described, malting. Some distillers add sugar and just use the corn for flavor. Some malt, some buy expensive amylase additives... Unlike rice, corn does contain some sugars. What I'm considering would be like 10 bags of the cheap frozen corn, boiled, about 4-5 gallons water, a lb of red yeast rice, and bakers yeast. Hopefully I get time sat, but I have to get some stuff ready to bring to my Mom's for Easter dinner. What's intersting is the chinese distill the rice wine into Scochu, and the red color will actually bleed into the distillate. I think that would be Uber cool.
 
Interesting. It hadn't occured to me to use malted corn rather then rice as the substrate. Though I suppose it's a fairly natural progression after the other grain experiments. Especially since corn is relatively neutral in flavor. That would make it more likely to yield something in the same general ballpark of flavor as rice.

I'm a little concerned that with the frozen corn+red rice yeast you are considering you would have to much water in the mix and actually retard the growth of the monascus purpureus. Though I did just run across an article that was using submerged cultures of monascus purpureus to boost it's pigment production. Since that wasn't really aimed at wine production I didn't read much of it though.

Another experiment that needs doing, though I'm not sure how to approach it, would be to attempt to separate primarily amylase enzyme from a fully saturated substrate.
 
Well I finally opened it! Smells sweet, fruity, and boozy! If I didn't make it myself I would swear it's fruit based. I din't taste any, because I had to hurry off to work. Tonight after work (1am est) I'm going to sit and watch the airlock for a while, if it's done I plan to strain out the solids and put it into glass carboys with airlocks for secondary fermentation, maybe another week or 2, then pastuerize. Here's some pictures of what's in the bucket!

I think I can reuse the solids for... Well if I was making hard liquor it would be "trub",... Anyways, I think I could steam more rice, add the trub, and not have to add yeast or Monascus... the cold crashing will send it dormant but it shouldn't kill it.... we'll see.

I was able to use the leftover starch mass from a batch of regular rice wine to start another. I broke up the starch into small pieces and mixed it into the rice. I did get some mold I didn't care for in it, but I think that was because the pieces of rice starch were to far from each other and allowed something else to grow in between.

The wine was fine, even with the mold.
 
2 am est... the verdict is in... Cold Crash... Although I'm sure it stopped on it's own already... whatever, I cand drink a jar and put off straining until tomorrow... Abbey hinks I should just get it over with... I think she wants some... No Abbey! Bad Cat! No drinking it yet!

20130330_014247.jpg
 
Hmm, I didn't notice there was a cat in the first picture until I saw the second. I have a tabby too.
 
I tasted it. Just Like That, all Gross looking like in the pictures. I was kind of scared and grossed out, but it was Good. Sweet... almost too sweet. Hawaiin Punch Like, thick kind of... I don't know, I drank some vodka and tonic (schweppes) first (no lime). I think people use the leftover rice stuff as like a desert or something, in asia.
 
Straining it out now... I think I might have messed it up... I put it on the back porch overnight to coldcrash, then I overslept, and it was 60 today, with my bucket in the sun... it's still good, but it's more tart now. It was waaaaaay sweeter last night. Just under 2 gallons and letting it drip, No Squeezies!
About 13%, I'm going for secondary fermentation, see if I can get that up a bit.

Off to the basement with them! My final yield, about 1.5 gallons... still dripping the trub in another bucket but not expecting too much more liquid.

Worried about the headspace in the half jug :confused:
I'm thinking of pumping in co2, usually an enclosed ferment will produce it's own protective layer... need to keep the oxygen out... On the other hand, my Mother asked about rice wine vinegar, lol.

You could always try to freeze concentrate it instead.
 
I made up an 18 cup batch of jasmine rice steamed 1/1 water to rice and a yeast ball per 3 cups. It's in a 3 gallon ferment bucket with an airlock. That thing took off the first night and bubbled like crazy up to @ the 18 day mark. Opened it up on the 21st day... and there's no @$%& liquid!?! The rice still has it all absorbed? So, stirred it a bit.. it's fairly mushy and wet, just no pooled water.. and going to try it again in another week. The air lock is only burping every couple minutes, so doesn't seem to be much going on. Smells absolutely amazing though.

My 20lb batch (Short grain sweet rice) that I used powdered up 1 lb RYR is going like crazy. I started with just two yeast balls and it wasn't doing anything after the first night (And I have no patience) so I crushed up 2 more and added those in a slurry of warm water. The air lock is almost a constant bubbling and has been since the 2nd day (Started on 3/23.) Hoping it turns out. I think I'll try just the RYR and some regular wine yeast next time. My first batch I tried used 3 parts water to 1 rice, and it was sour, sour, sour. 2nd batch is the one with no liquid. Hopefully, 3rd times the charm? lol
 
21 days? You sound plenty patient to me. I'm fermenting at around 72F if that helps, and I was 9 days to racking off to the carboys. It got a little sour from my oversleeping and leaving it in the sun, but not too bad. It lost a lot of sweetness though.... more like tart than sour. And dry, really dry.
 
Looks awesome. Definitely considering doing this project during the summer, so I'm interested to see what the best method is (filtering, secondary fermentation, etc.) to get a good final product. Subscribed.
 
I have an experimental corn and ryr ferment going, with added bakers yeast, took off like a rocket then stopped in about 12 hours. Like, completely stopped. After 2 days of nothing, the airlock started up again, but slowly, very slowly... I have some time off Friday, so I plan on putting down another batch of Rice. I haven't made up my mind yet if I'll use ryr or the winecakes. I pasteurized mine last night, so that batch is over. Got about a gallon and a half of cleared, filtered, pasteurized red wine. It's good, but might neeed some backsweetining, not sour but very dry and tart. Very boozy.
 
I think that is why they call it red YEAST rice.
Well if you knew that already, why did you wait so long to enlighten us? There are many inexact translations between the 2 languages. I don't think somebody buying asian ingredients they are not familiar with should take anything for granted. I read about 30 articles on monascus before I found one describing it as a strain of yeast. Anyways, now I know..
 
Corn/ryr/bakers yeast airlock activity is picking up again, so that's good. I'm off Friday, I'm leaning towards a bucket of ryr and rice only, because I have all that, just takes so long to steam all that rice. I have some other brew to get finalized, see how much time I get.
 
Ok. I setup 4 more experimental batches.

RYR with jasmine rice.
RYR with jasmine rice, and distillers yeast.
RYR with Extra Long Grain rice.
RYR with Extra Long Grain rice, and distillers yeast.

All of the rice was cooked the same way as the last set of experiments. The rice was soaked for an hour, and then rinsed. Cooked in a rice cooker with a 1:1 ratio of water to rice. 1 1/2 cups of dried rice to a jar. Each batch got 3 tablespoons of crushed red yeast rice. The ones with yeast also got 1/2 tsp of dry yeast.

The rice was cooled, then broken up in food grade buckets and the RYR and dry yeast sprinkled over them. Then the whole thing was tossed until everything was thoroughly coated.

I hope to learn three things from this experiment. First, if an additional type of yeast is needed when making red rice wine. Second, if the enzymatic action of the red rice yeast is adequate to break down the long chain carbohydrates from the Extra Long Grain rice. Finally, if the enzymes produced by the RYR really do result in a more complete breakdown of the rice then the mold from the rice yeast balls.

I also have another batch with jasmine rice that was made with rice yeast balls I made on Monday. It won't be a perfect comparison, but it should provide a good point of reference for the rice breakdown.
