The Algonquin is a very old classic that dates back to at least the 1930s. It features rye bourbon with dry vermouth and pineapple juice, which makes for a sweet, easy-going, slightly tropical cocktail.
The Cascade Cocktail is an extremely sweet cocktail that tastes like blackcurrant (or raisins) with hints of grape and spice. I find it too cloyingly sweet, so I added my own variation (Recipe #2) which waters those two ingredients down with gin.
The Bermuda Highball blends brandy with gin and vermouth, and adds a couple of marrying ingredients to make the whole thing work. It tastes like a carbonated martini that’s had some fruit and wood notes added to it.
