Hi Steve

I ran my own tests on this some years back by splitting small batches of
dry clear wines and treating each half with these chemicals. I feel the
results were notable. While I cannot really detect sorbate in a wine, I
_can_tell the difference when these wines are compared side by side.
The Benzoate gives a somewhat "brighter", cleaner tasting wine. While
I still sometimes use Sorbate on "sweet" wines (eg end SG >1.007),
I now have a large preference for Benzoate in "off dry" and "medium"
wines. No real science here, simply an empirical determination.

The "commercial" world has rules, and one of those rules is that Benzoate
cannot be used. As always, rules don't have to make sense but they_do_
have to be followed. Home winemakers are not bound by these rules
and can therefore do as they think best.

If nothing else, Benzoate does have one advantage: No geraniums.

Both chemicals are effective, so I suggest that you split a batch of wine
just as I did, and make your own determination which one you prefer.
Sugar tends to "cover" this difference, so I suggest that you try it
on an "off dry" wine. HTH
