My wife totally has the soap thing, and I must be a carrier for that gene, because I can see where the soapy flavor is coming from, but it doesn’t bug me.
Perhaps your wife has two copies of the soapy variant of
OR10A2, but you have only one? I.e., your wife has (C;C) at rs72921001, while you have (A;C).

That seems likely!
