G'day Tinepole.
What do you mean by "normal yeast" do you mean, bakers yeast or some other sort of home brew shop product ???
I am only new here myself but I'll have a go at answering.
I have only tried the Still Spirits "Turbo Classic" yeast as far as home brew shop yeasts are concerned and I only used one the first time I did a wash.
From what I read the home brew shop "turbos" are more about getting the highest alcohol % and no so much about making the best flavoured spirit possible.
A mate of mine tells me that the still spirits "Triple Distilled" has produced a much better neutral spirit for him than the regular "turbo classic"
When I made my Turbo wash it smelled really bad, I have a reflux column and want the best cleanest smelling neutral I can get so after some reading I ended up here -
http://aussiedistiller.com.au/viewtopic.php?f=32&t=8The link is for a Tomato Paste Wash, it's a "supermarket" ingredient wash designed to be both cheap and produce a good clean neutral product.
If your using a pot still you will be after something different to this I guess, and I imagine others here have used the exact yeast you speak of though and will be able to offer you more insight into what it is like.
Good Luck. :)
