1) If you hold whiskey isn't chometz.
2) If you hold chametz @ 1/60th becomes butul before pesach.
Not backed up at all. Just contemplating.
1)The only tzad heter to my knowledge say that whiskey isn't chametz (or my correctly, is chametz nuksha, or zeas chametz) is a tzad of a shoel in a noda beyehuda. In the teshuva the NB has a workaround and doesn't address the point. hardly an endorsement. There may be a biur halacha that brings this as a non halachic point, but I couldn't find it last time round.
2) 1/60th batel before pesach helps how? I did ten times better for you, I said if it's ,ore than 5/6 corn (1/6) you can drink it.
