Dolin Bitter Chambéry is made by the last remaining vermouth house under the Chambéry appellation, using plants, herbs, and fruits. It's bittersweet and delicate, making it perfect for a Spritz.
Cranberries, grenadine, dark chocolate, and rose.

This appears to be Dolin's response to Martini Fiero. They are similar, but as you'd expect from a comparison of these two houses' products, the Dolin offering is a bit less sweet, a bit more complex, and a bit more expensive. I like it a bit better. Absolutely made for a spritz or tonic, and I can even imagine drinking it plain over ice. Will not replace your boozier bittersweet red aperitivos (you know the ones) in their traditional roles, should you be considering it.
