The Harvard Cooler is an apple-brandy highball lengthened with Carbonated Water and lightly sweetened with Simple Syrup. The finished drink is spirit-led but refreshing, with soda carrying the apple aroma through a long, cold serve.
What You'll Need
Ingredients
- Apple Brandy - provides orchard fruit and spirit depth.
- Simple Syrup - adds restrained sweetness.
- Carbonated Water - supplies dilution, length, and fizz.
Equipment
- Collins Glass
- Jigger
- Bar spoon
A Defined Soda Top
Four ounces of Carbonated Water against two ounces of Apple Brandy gives this cooler a repeatable 2:1 mixer-to-spirit balance. The quarter-ounce syrup rounds the spirit without making the drink sweet.
Substitutions & Variations
- Use Calvados for a more specific apple-brandy profile.
- Add aromatic bitters for spice.
- Replace soda water with ginger ale for a sweeter variation.
- Express both lemon and orange peel for extra aroma.
Helpful Tips
- Chill the soda before building.
- Fill the Collins Glass with plenty of ice.
- Add the soda last and stir briefly.
- Refrigerate any opened fortified or fruit-based modifiers used in variations as appropriate.
