Thanks for the suggestions. I'm in Saskatchewan and I've heard of Dillon's, but I don't remember seeing it in stores.

I do enjoy a rum old fashioned (with split Angostura and black walnut bitters and maple syrup) and a Oaxaca old fashioned. Rum old fashioned hits pretty close to bourbon old fashioned for me, but also leaves me with a terrible headache the next day when I have too many of them 😅.
