I was searching around to try and find out if it's ok to filter turbo mash/spirits with a reverse osmosis system and had no luck. I need to filter my batch so I can add essences, but i'm not a fan of using activated carbon in the least bit.

Hello Ig. Reverse Osmosis is used in labaratories to further dry ethanol. The eq is extremely expensive as not plastic and normal metals can be used. Used for makeing annulaR alchohal. Deadly stuff.

For out needs, good reflux operation is all thats neccessary. Barring that, is activated carbon to clean it of oils. I use a 6.5 gal. glass carboy, fill it with a half pound of activated charcoal and let it sit, swirling it when time permits. Pour off as needed. Usually at 55% ABV. Works wonders. Can do same in gal. jugs also.

Activated carbon is your best and safest choice.

Why don't you like it?"

Thanks for the fast reply. At the moment a carbon filter apparatus is too expensive for me. All I'd like to do is strip the turbo mash of its horrible taste and basically make a half strength vodka for the purpose of adding flavor or mixing with fruit juice. With carbon I'd have to run all 6 gallons through multiple times to get the purity I'm aiming for which would be a very lengthy process. Would adding carbon straight to the (cleared out) mash or using any other filter methods take away the awful taste?

Anyone ever tried using a Brita or Pur Filter?

"Yes, brita filters do work but with a catch. They can make taaka taste just as good as goose IMO with just a couple runs, but I've read that the alcohol leaches impurities out of the plastic which poses a health risk for the drinker. When I heard about that I quit filtering cheap liquor through my brita setup.

Edit: There's a filter called gray kangaroo which you can attach a cheap liquor bottle to and an empty bottle on the other side that's supposed to work but I've never tried it. I'm considering making a device based on that concept where I can just attach 2 - 1ltr bottles and fill one with spirit, then invert it and have it filter away. Come to think of it, that wouldn't be too hard as long as I can get some chemical tolerant plastic fittings and a reservoir for carbon in between the two. I'll get back to you on that one"

"You want some really clean product?

Try this. Don't ferment over 14% Abv

Let clear totally. Like water. Add sparkaloid or other if in a hurry otherwise wait at least a week or more till totally clear.

Rack off carefully, leaving all leas in bottom. (sediment).\\

Strip the run. Fast and dirty collecting everthing.

Put stripped low wines in a container and add bakeing soda at 2 tbs/gal. Swirl when you can. Blow some O2 in each time.

When you have stripped enough, 3 or 4 times, do a sprit run, slow and with deep cuts. Cut deep as you can redistill the waste heads and tails later.

After distilling and haveing caught all product in small jars, numbered, let sit overnight or best for several days with a coffe filter or paper towel over the top.

Smell taste and combine the small jars. Any off tastes add to faints jar. Later to recycle. Cut to drinking strength. Let merge for at least a week.

If not clean enough for you, put into a jug with the activated carbon and shake and swirl as you can. Week or so later filter through coffe filter over a ss strainer or whatever you have.

You can't buy any better. You can order a jar of glycerine to help smooth it out and give it mouth appeal.

I won't be distilling for at least a month since I don't have my still yet. But thank you Walker, that does help (for when I get my easystill)

"good morning walker and ig,
i would advice against the easystill. i have one and it is okay but i ended up buying the ee2
and the 1100 watt hot plate. the increase in cost is well worth it. after a little while in the hobby you will see how limited the easystill is in both volume and versatility. i hope this helps.

just me"

I use the gray kangaroo and it works great, its cheep with a life time supply of free refills for just shipping and handeling. I first got it for buying the cheepest vodka I could find running it through the gray kangaroo four times and ending up with real good stuff. snidlywhip

"Hey Just Me. I live with my brother and sister in law which own the house. They don't care if I brew, but they don't want me distilling for safety/size reasons. After discussing the safety and compactness of it I was given the go-ahead by my brother to get an easystill so I've gotta make do with that.

Snidlywhip, how many run-throughs can the kangaroo filter take until it gets spent? Is there any way you can take the center piece apart to put in your own carbon? I was wondering because on their website it says when you send them in they send you a refurbished one which probably means they take apart old ones and just refill them unless they use steam blasting to clean them"

The device I have and all of the info states 50 liters per filter. When I purchased it what came were two center filters and unlimited refills. It is not obvious how the center comes apart. It must because they just change it out. I can not see the trick to opening it. I think they do that to keep the return business. One thin I can say is it works Real Well, but so does carbon in the carbouy and just filtering it out when you bottle. For me it is the ease of use with the Gray Kangaroo. I think you could make one if you are good with that kind of thing. There system works very well. Snidlywhip

"Ig
You can build your own carbon filter out of pvc pipe for just a few bucks.
Not expensive at all. I built one several years ago that worked flawless.
Once you get into distilling more and more, you will find that filtering is not needed when you get everything right. I have not used a filter in years but I keep it around just in case I get in a hurry and screw a run up. Most of the time if the taste is not there you just throw in with another batch and clean it up. Also if you are going to be using essence on your spirits it does not have to be so perfect, the essence will hide more of the off flavors than you think.But if you take your time and make good cuts then use the essence I don't see where you would need any filtering.
Good luck with any direction you go , and always ask questions too."

that i understand. the easystill is a good product . there are a few discussions in the archives. just do a search. first do a stripping run then dilute to 50%. run again and collect in seperate jars every 20 minutes. you just have to make smaller cuts with that still. enjoy.
