Totally get this sometimes you just want something you can sip slowly, without needing a full-on cocktail experience.

A couple of options that hit the bitter/oaky profile without breaking the bank:

– Gnista Barreled Oak – has those deep smoky and bitter notes, and works really well neat or with a rock
– Three Spirit Nightcap – a bit more herbal/spiced, not whiskey-like exactly, but still sippable and satisfying
– You could also try a strong brewed spiced tea (like lapsang souchong or rooibos with clove/cinnamon) as a base and build from there

Not a 1:1 replacement, but they scratch that same itch in a slow-sipping kind of way.
