The scotch is aged in sherry( i.e. wine) casks specifically for their flavor, it is therefore, like a davar hamamed which is never batal. I heard from a Rosh yeshiva that both Rav Dovid and Rav Ruvain Feinstien hold this way even though hR’Moshe was reported to have drunk such scotch., The head of the OU was on headlines a few months ago and he stated that there are many bases to be maikel (e.g. the scotch may be from the tenth “pouring” when there is zero flavor left) but that the OU does not rely on bital ever, as a matter of principle.
