Here, two emergent trends in tonic collide: first, the trend towards tonic syrups: concentrated, sweet, herbal concoctions designed to be diluted with soda water before drinking. The second trend is that of “companion” tonics: that is tonics made by distillers, crafted in such a way that it perfectly compliments the spirit.
As you know by know, the “recipe” or ratios that are recommended vary from tonic to tonic. Here is Pinckney Bend’s:
1 part Pinckney Bend Gin 1 part Tonic Syrup 4 parts Soda water stir, and garnish with a lime wedge.
Thoughts: most tonic syrup ratios advocate for 2 parts of their gin. This is a case where “companion” should be taken quite seriously to understand. Their gin is a little stronger than most [93 proof] and has a good deal of heat. For companion purposes, I think this ratio works. For other gins, I’d suggest perhaps looking a bit closer to the 3 parts soda, 2 parts gin, 1 part tonic, that most bottles lean towards.
