First...yes, I fully admit I'm lazy and uncultured.

I've been getting into drinking Old Fashioneds at the bar. Most of the time, it seems like the bartenders also use a pre-made mix and add it to whiskey. So now I want a decent pre-made Old Fashioned mix to add to whiskey at home.

A co-worker likes the Proof traditional syrup (and they sure love to live in my Facebook feed), but I'd love to hear other recommendations.

I left the thread title a little open-ended to allow for suggestions/recommendations/reviews of other mixes (margarita, mojito, sours, etc.).
