No commercial outfit uses refined white sugar as substrate. It
doesn't fit the TTB or other world bodies' rules. If you make a
product from white sugar, you can't legally call it "Vodka". It
is "White Spirit". Even most of the white spirits have to be grain
based by law, hence the industry name "GNS", meaning Grain Neutral
If you really 'must' use sugar as the substrate (assuming it passes
approval of the authorities you're dealing with) then use "Raw
Sugar". This sticky brown unrefined & unbleached product still
contains a fair amount of molasses, thus it has most of the
nutrients your yeast needs. All you need do is add boiled yeast
sludge from a previous fermentation to provide lipids & other
nutrients. That's efficient recycling at its best. It's also cost
effective, as you aren't spending money on extra outside nutrients
or on EPA requirements to sanitize your distillery effluent before
putting it into the environment (you do know about that, don't you?).
Propagate your own from a culture for each fermentation. Very cheap
to do and relatively easy. There's plenty of info out there on
doing this - I recommend you start by reading the excellent online
info by John Palmer "How To Brew". It deals with all aspects of
making beer including all grain worts, yeast harvesting &
propagation (Yeast Ranching). Much of what he's written is very
relevant to the distilling industry.

3. Bakers yeast:
Using bakers yeast is a proven and acceptable method in distilling.
Used correctly, it can produce very fast fermentations (48-72 hrs),
thus reducing the chance of bacterial infections. It was used
commercially for centuries to make some of the world's most famous
Scotch Whisky. As a baker with 30+ year's experience in a previous
profession, I've seen all sides of using bakers yeast. Many of the
so-called specialty brewing & distilling yeast strains used
commercially today were first discovered as mutations of bakers
yeast (Saccharomycetes Cerevisiae). Interestingly enough, evolution
has come full circle as it was wild yeasts used in brewing &
winemaking that were subsequently harvested after brewing was
complete to produce ancient breads & other baked products. Life's
Wouldn't use 'em, unless I was desperate. But then I'm not that
desperate. I have trialled one for a commercial outfit which was
very good, but relatively expensive, and difficult to get on a
regular basis. Plus it didn't really perform much different to what
my home-ranched or bakers yeast does. Most of the flavour (or lack
of) in distilled products comes from a combination of distilling
technique and aging. Yeast doesn't provide much more than the raw
ethanol to work with. Some specialty yeasts make particular
flavours in worts, but much of it is lost again once it is distilled.
