Yes, unfortunately Kahlua has long been discontinued. We started production of another coffee infused cigar soon after and we think all you Kahlua fans would love it. It's called Tabak Especial, ask your local tobacconist to order some!
Unfortunately Chateau Real did not sell as we had hoped and, as such, we were forced to discontinue its production. It is still lurking in some shops, so try to find them before they're gone forever.
