Is selling rum raisan ice cream flavor harram (rum) artificial flavor?

Alhamdu-li-llah wa as-Salatu wa as-Salamu ‘ala Rasool-il-llah,
There are two different types of such flavor: one uses rum and the other doesn’t. If actual rum was used, then it is forbidden to consume, and subsequently forbidden to sell. If not, then it would be halal.
Allah knows best.
