Hello Julien, I would be delighted to walk you through the preparation of a classic Tom Collins.
Here is the standard, balanced ratio measured in centilitres (cl):
- Old Tom Gin: 4.5 cl to 6 cl (4.5 cl is the classic International Bartenders Association standard, though 6 cl is often used for a slightly more spirit-forward profile)
- Fresh lemon juice: 3 cl
- Simple syrup (1:1 ratio): 1.5 cl
- Soda water: approximately 6 cl to 8 cl (to top off the glass)
Regarding the preparation method, a classic Tom Collins is traditionally built directly in the glass rather than shaken. This direct build method is historically what distinguishes a Collins from a Gin Fizz (which is always shaken vigorously with ice). However, some modern bartenders prefer to briefly shake the gin, lemon juice, and syrup before straining into fresh ice to ensure maximum chill. For the classic and authentic style, building it straight in a chilled highball or Collins glass is the standard technique.
Step-by-step preparation:
1. Prepare your glassware: Take a tall Collins or highball glass and fill it completely with fresh, solid ice cubes.
2. Add the base ingredients: Pour 4.5 cl of Old Tom gin, 3 cl of freshly squeezed lemon juice, and 1.5 cl of simple syrup directly over the ice.
3. Initial stir: Use a long bar spoon to gently stir the mixture for about ten seconds to blend the citrus, syrup, and spirit while initiating the chilling process.
4. Add the effervescence: Top the drink with roughly 6 cl of well-chilled soda water, pouring gently down the side of the glass to maintain the carbonation.
5. Final integration: Give the cocktail one gentle upward lift with your bar spoon from the bottom of the glass to combine the soda with the rest of the ingredients without knocking out the bubbles.
6. Garnish: Add a fresh lemon wheel (or wedge) and a maraschino cherry on top, and serve immediately.
I hope this thorough guide helps you craft a refreshing and perfectly balanced cocktail. Please let me know if you have any further questions about measurements or adjustments.
