Toi:
R’ Moshe himself writes in a teshuva that whiskey blenders could be problematic so he refrains from drinking whiskey with a blender inside when not in public. cholov stam is lichoirah less problematic.
DaasYochid:
Toi, your “lichoira” is lichoira wrong. He writes that he drank
blended whiskey in public, but didn’t say that about c”s.
Why should he have to, DaasYochid? He wrote to be mattir it,
not that he thought it might be a problem.
