Q. If one goes to buy needed kosher wine to a liquor store that sells both kosher and non kosher wines during Chol Hamoed Pesach, is he allowed to to remove some chometz liquor bottles, in order to reach the desired kosher bottle?
A. Shulchan Aruch (O.H. 446: 3) rules that if the chometz of a Gentile entered one’s property it should be pushed away with a stick and not be touched with the hands, even on Chol Hamoed. Mishna Berura (ibid. 9 – 10) adds and explains that he should avoid touching it with his hands, so he may not come to consume it.
Poskim seem to disagree if he is allowed to tell a Gentile to bring him the kosher bottle. (See Mishna Berura ibid. 7). Horav Shlomo Miller’s Shlit’a opinion is that he may ask the Gentile to bring him the kosher wine.
