Old Tom gin was popular in 18th-century England, and has had a bit of a resurgence in the craft cocktail movement. From Wikipedia, “It is slightly sweeter than London Dry, but slightly drier than the Dutch Jenever, thus is sometimes called ‘the missing link’.”⁣

Casino is a perfect gin drink. It is tart and a little sweet, and the Old Tom gin has a lovely flavor. In fact, I think Old Tom gin might even appeal to people who don’t think they like gin. ⁣🍒
