Improving yield

Just starting out and need some advise? then post it in here.

Improving yield

Postby Rolls912 » Wed Jan 09, 2019 11:59 pm

Soooo, just finished processing 100litres of TPW and ended up with 4 litres of clean neutral. Doesn’t seem like a good yield to me considering the heap of time (20hrs) it takes to process it :handgestures-thumbdown:
Q. Is there a way to make a good neutral from Turbo’s? Everyone one seems pretty unimpressed. Has anyone experimented with variations to the recipe?

A few more basic details would go a long way ta help ,sounds low for sure 4lt@95% alc or 40%,checking wash with a hydrometer to confirm fermentation is complete I hope,I see you running a modded T500,any neutral still were packing or refluxing is not spot will give shit results regardless of how tall it is ,20hrs sounds fast to process that amount,again a few more details .cheers hillzabilly ;-)

Even at 8% wash for 100L that is theoretically 8L of pure in there, so that does seem very low (I usually aim to get my sugar washes around 10% abv finished).

Was the ferment complete?
Did it stall?
Did you check starting and final gravity?
What sort of cuts did you make?

One thing to consider on top of what has already been said.

If your wash was 10% (a guess) then you only have 10 litre of ethanol maximum. Given you cannot collect 100% of the ethanol that reduces the overall amount. Taking heads and tails into account, 4 litres at 95% would be a reasonable yield if you were harsh on your cuts. I usually end up taking around 45 to a 50 percent of the collected volume as hearts. The rest goes into feints for rerun at a later stage.

I'm with professor green. I usually take about 50%.
If you want a higher yield in shorter time bigger boiler and bigger still is the only way without sacrificing quality.

I doubt there is a way to make anything good outa turbos :naughty: I don’t blame them, they must have good tastes :handgestures-thumbupleft: I thought tpw used bakers yeast :think: there would be an improvement for u....

We usually get about 10L of 94 out of 200L of tpw after fairly tight cuts. It's enough for 2 batches of gin returning about 8 or 9 litres of drinking strength product per batch.

Ok thanks.

I was hard with my cuts so that yield sounds about right then :think: A lot of work for such a small amount of pure. Hence my turbo question. The 2inch is just too slow!

I do have another 4 litres of spirit that smells really good. Not pure enough for gin though. Don’t know whether I should fients run it or something? Seems too good to reprocess....

I did measure wash but I’m not near my notes. Will check and repost. (This was the wash where I used 1 x full dextrose and 1 x half dextrose/half plain sugar. I believe both were fully spent before I filtered and distilled. Only real difference is that the full dextrose finished quicker + had slightly lower ABV.)

Maybe you could try one of the cerial washes next and make a whiskey instead of a vodka?
You can still make gin from a cerial based wash, will have a different mouthfeel but it will actually be enjoyable to drink the stuff not destined to be gin.

If it smells and tastes OK, use the other 4 litres for vodka. 4l @95% is around 13 bottles at correct drinking strength.
Or, re-run it with feints from your next batch.
Or try doing 2 batches of gin, one with the hearts cut, one with the other 4 litres and see what the difference is. Other than the cost of the botanicals, you've not really got much to lose.
