This is a recipe for a homemade red wine syrup that was first used in the Brandywine Sour, a dessert cocktail created by bar manager and author Nick Mautone. First published in his book The Artisanal Kitchen: Holiday Cocktails, this version is as close to the original as possible but may taste different depending on the type of red wine used. Unfortunately, this also affects the amount of sugar that should be added when making the syrup, so make sure you adjust the quantity if needed based on the brand and type of wine you use if you make this at home.
Add 300 ml red wine to a saucepan.
Heat over medium high heat until simmering.
Add sugar and heat while stirring for 3-5 minutes until sugar is dissolved.
Remove from heat and let cool for 5-10 minutes.
Strain syrup through a fine mesh strainer 1-2 times to remove any sugar particles.
Pour syrup into a squeeze bottle or pouch with a spout using a funnel, then refrigerate or freeze.
