If you are after neutral\vodka - it makes sense that a mild unoffensive tasting wash in the still produces a product that tastes better coming out the still (most of the time

)
I'm a big fan of sugar washes - no turbo basher here - I just like the price the way I do it - I have used turbos recently to finish a stuck wash, they are handy to have on hand.
I currently use 3 x 5g packets of yeast started in a large jar 3 days before putting the wash down to breed them up - this costs around £3 so comparable to a turbo - I pitch this into a 50-55L wash along with a "yeast bomb" nutrient which cost about £1 and half an hour of your time to make up.
At this I'm already ahead money wise, as my wash is twice the size and only 1.5 times the cost of a turbo.
I when i strip the wash I scoop out a large jar of the yeast and add some water to it (to keep the yeast happy)- this will be my starter for the next 50l wash - i scoop out half the lees from the bottom of the fermenter and chuck it, I then add the hot backset from the still to the fermeter\lees melt the sugar, top up with water, add a little vitamin B, top up with water and pitch the starter when cool. (yes it stinks like sugar strip - but tastes fine - the smell dies down when it get fermenting again)
Now I have 100+L for a little over £4 of yeast\nuits.
I repeat this process, adding another yeast bomb - and 2 fresh packs of yeast for the 3rd wash.
I do 4 washes in total before starting again. I basically get 200-220L wash from £5 yeast and £2 of additives - its recession proof stilling.
EDIT: I forgot to mention - when using a lot of backset as I do it is necessary to adjust the PH with something like calcium carbonate - as it gets very acidic and will stick. I use a benchtop PH meter and shoot for 4.5-5PH before adding the sugar - indicator strips are fine too.
