Salt effect distillation with sugar

I've been nosing around on the web again and carefully researching the "salt effect" on distillation. This idea that by adding salt or in our case sodium bicarbonate it is possible to selectively mess with the boiling point of the water to effect better separation. In my searchings I came across som...

Re: Floral notes in Gin and advice in general

Actually I just looked at an article regarding the decay of cucurbitacins during the drying of wild cucumber. In it the research established that in order to preserve the cucurbitacin content the fruit had to be dried at 52 degrees Celsius. Any higher or lower and the little buggers broke down. Chri...

Re: Floral notes in Gin and advice in general

Chris's idea of using dried cucumber might be something to try, when I did it the cucumbers were still wet. Extracting plants while still fresh in 90%+ etoh actually draws out a broader range of phytochemicals due to the afore mentioned entrainment effect. Usually that's ideal for making herbal reme...

oh, I forgot to add.... Cucumber and mint: pain to work with via post distillation masceration. Comes out tasting rather like fresh grass clippings al a mint.

Re: Floral notes in Gin and advice in general

Well it's hard to account for the total loss of botanical notes unless your gin making set up is somehow malfunctioning or your sense of taste is shot. No matter how neutral or not neutral a spirit is the flavors of the botanicals should come through very clearly, they may even be strong enough to c...

Re: Copper vs. Ceramic

Oh yeah, the higher surface area is gonna be much more prone to corrosion. I'm zealous about cleaning stuff, the copper especially. Let em soak in a hot vinegar and table salt mixture for an hour and they'll be super shiny again I'll wager. Follow up with a rinse in foreshots and let em dry. Especia...

Re: Copper vs. Ceramic

Well while these little rings may not be my best bet for higher ethanol purity i've been mulling over another experiment involving the reflux-fractionation of gin. The rings would be easier to clean of essential oils than scrubber packing and if the experiment plays out well I'll use them for just t...

Re: Copper vs. Ceramic

Well I won't argue that though the flavor benefited a bit, the grain character came through a bit more. Probably won't be converting to rings as an ongoing thing but it's interesting to play with.

Re: Copper vs. Ceramic

Threaded rings, that's almost like spp. I've considered making spp using a power drill set up but that's probably a ways off. Threading condenser tubes though, now there's a novel idea. To induce turbulence I assume? I wonder, which is better a rough surface or smooth Fog seems to prefer condensing...

Re: Copper vs. Ceramic

Well, the proof suffered very little, I pulled 90% vs. the 93% I usually pull at high reflux. It was mixed packing, rings on the bottom and scrubbies on top with the rings taking up about 3/4 of the column. No distinct difference in performance, better stability with take off but that may be also du...

Ah ha! There's an answer. Ok, browsing all the threads on packing materials on the forum gives a lot of mixed view points and can be overwhelming.

Re: Copper vs. Ceramic

If your thinking about making them the shape of ceramic rings the copper rings would have far less surface area as the copper is smooth. It would make your column heavier as well. Lava rocks are very porous, light and cheap (buy black not red). Actually that's why I'm sanding them, to rough them up...

Re: Flame test of alcohols

The only thing i've ever been able to deduce using the "flame test" on product taken off the still was a rough gauge of proof. A tall blue flame with a pronounced gold cap that leaves the spoon dry is gonna be 85%+, the more tall and pronounced, the higher proof. A lower blue flame with little to no...

Re: Brown particles in my stripping run?

My guess is oil from the grains, especially corn. I don’t clean my still a lot, just a rinse most times. I will get a lot of this stuff stripping grains, and little to none in spirit runs. Will get a lot with AGs, and none or little making rums and neutrals. When I get a little I figure it’s residu...
