I made my turbo that came with the airstill and it was a success. I got 5 litres of 40% alcohol which I added a brandy, a vsop, a spice rum and two gins too. The brandy sachet tasted more like metaxa which I enjoyed, the vsop hit the spot for me. The gin is making waves with my parents and the spiced rum was supped in no time. So all in all for a turbo or my lack of taste buds I was mighty impressed.
This morning I bunged on a tpw to trial it out, its frothing like a meth addict going cold turkey. What % should I expect from a single 4l charge?
I have been looking into vodka star aswell, what can I expect from avodka star wash and will it need the refinement of the my original turbowash ie, liquid carbo, turbo clear, final filtration etc.
All in all cheers guys for your help so far, I am certainly enjoying this cheeky little air still and the hobby along with it.

Dunno about the numbers Phil. I used to use the SS Triple distilled turbo yeast along with the carbon and finings (just following the instructions) successfully. Yes I do have a "Z" filter with which I carbon filter all my neutral before mixing, but that wasn't always the case (It just helped to speed things up when I got my T500).
These days, I just do vodka star but no carbon, and I don't bother with the finings either. I just make the batch as per instruction, then after it's finished fermenting, I leave it an extra week or so too clear naturally as much as it can.
I then just fill the smart/air/easy still, some boil enhancers (rashig rings, and some slices off a 15mm copper pipe) and some distillers conditioner, then fire it up and do that as a "stripping run" (I leave it until i'm getting about 10% ABV in the collection bottle or testing tube). I just keep doing stripping runs until I've run all the wash, then I measure the collected "low wines" and let it down with reverse osmosis water to <40% ABV, then do the spirits run (dumping the first 25ml per still charge). I don't bother doing the cuts etc that some like to do (because it's just sugar wash and the sugar is already well refined, producing very few off flavours/notes in the spirit IMO). I keep it all running until the product is coming out the still at 40%. The first part is kept to be let down to 40% for carbon filtering and flavouring. The still is left running and the rest is just added back into the other low wines waiting to be run for spirit (I hope this makes sense).
It doesn't need filtering generally but I do, because i have the kit........
It's hard to give an answer about numbers as it depends on how much alcohol is actually produced by the ferment in the first place. A good example is that if you calculate the difference between your start gravity and your finish gravity and the difference is 100 points (SG 1.100 and FG 1.000 for an easy example) then the wash will be 13.58% ABV - in other words if you could distill to 100% alcohol, then you'd have 3.395 litres. Obviously the wider the difference between start and finish numbers the greater the quantity of pure alcohol in the mix.
Most turbos seem to work on about the 14% area by using 6kg of sugar to 21 litres of water (which often ferments down to 0.990 so you get a bit over 14%). Of course, you could use a wine yeast with a higher alcohol tolerance and then use some wine nutrients to get a greater level of alcohol, but I'm a believer in not being greedy as that can lead to off flavours that come through in the spirit at the end.
I've yet to find what I consider a good/nice tasting brandy essence (I was spoiled many years back, having the chance to taste some very good, very expensive brandies - which means I prefer Armagnac to Cognac, and French over Spanish or Greek equivalents).
But I find many of the essence flavourings do come out very good...........
