If there is only a little coffee in the taste of wine, it is kahlua with milk, and if there is only a strong milk flavor (with a faint cocoa flavor), it is baileys with milk.

As for the name, each bar usually has a different name. Generally, it is directly named after the raw materials, such as "coffee milk", "Bailey milk" or "Irish barn", which means Bailey milk, because wine is produced in Ireland and the raw materials are grains.

Don't want to write too much. Typing is very tiring for me. I hope I can help you a little. If you don't understand, you can talk to me alone.
