I'm admittedly partial, but I really enjoy 1835 as an anytime whiskey. Very tasty and very affordable. My special occasion whiskey is garrison brothers and that stuff is just delightful.
I've seen a lot of recipes for an old fashioned, but my pref is 1835, simple syrup, dash of bitters, splash of water. Ice is acceptable.
The only thing I will mix with garrison brothers is the glass I poured it into. To mix or dilute with anything else is accurately described under article 4 of the Geneva convention as a crime against humanity.
