My go to bourbon for cocktails is the Elijah Craig Small Batch, mainly due to price. My sweet vermouth recommendation is the Death & Company house sweet vermouth, equal parts Dolin Rouge and Punt e Mes. I prefer that mix to something like Carpano Antica Formula Sweet Vermouth, but you can get that in a 375 ml bottle.
