Subtract the post fermentation specific gravity from the pre-fermentation sg and multiply by a factor.
(final sg) - (starting sg) * 133
1.092 - .992 * 133 = .100 * 133 = 13.3%
There is much discussion about the factor, but that's the one I prefer.
If your question "ABV of a finished wine" indicates that you don't have both sg readings, then you have two choices...
1) vinometer - cheap and totally inaccurate (there is a thread about this)
2) send it to a lab - expensive and very accurate
Hope this helps.
