London Beis Din and Dayan Chanoch Ehrentreu – All scotch is OK.
R’ Don Yoel Levy of the OK in a shiur which I attended explained that the barrels are burnt before reuse and that there is no chashash of any contamination let alone noisein taam. It is all marketing.
Rav Landa: Very little whisky is acceptable. All I remember is that Woodward Reserve bourbon is on his approved list.
Admou”r meCreedmoor: Only whisky aged in barrels which have been burnt for insurance purposes, in a similarly immolated distillery, is acceptable. Otherwise, it is meshibich to make kiddush on Iranian crude under the hashgocho of Ayatollah H. Rafsanjani.
