Q. I have attended simchas and parlor meetings in houses where the host claims it is all done under COR supervision and found that they serve Baileys or Kahlua liquor. Are those liquors under COR hechser?

A. We forwarded your question to Rabbi Tzvi Heber, Director of Community Kosher – COR
The following is his reply.

“Thank you for your question.

Bailey’s Irish Cream is not allowed at COR certified events. Kahlua is allowed only if it is bottled in Mexico (if it states “product of Mexico” it is not allowed). Furthermore, COR does not allow the use of previously opened whiskey bottles or even whiskey bottles that were purchased prior to the most recent Pesach unless they were sold by a COR Rabbi.
Please be aware that it is common for people and organizations to order food from a COR caterer into their home and use a waiter to serve it. Alternatively, they may ask a COR caterer to cater an unsupervised event. This is done in situations where a mashgiach is not a possible option; for example, where they want to use their personal own dishes or their own whiskey. More information about unsupervised events can be found in an article called “Unsupervised is Uncertain” on our website at http://cor.ca/view/537/when_it_comes_to_kosher_affairs_unsupervised_is_uncertain.html
 If you require any more information, please feel free to call me.
 Best regards,
Tsvi Heber”

A similar opinion is to be found in the Star K list.
