Add spirit up to the neck of the bottle. Give the bottle a shake for 1 minute, then refrigerate for 6 hours.
At this point the kit will be ready to use. Grab a cocktail shaker, add ice.
Add 1 or 2 measures of the cocktail, plus a mixer of your choice (see individual product listing for suggestions).
Shake hard for 10 seconds. Pour into a glass and enjoy.
Please note: The strength of your cocktail depends on the ratio of spirit to mixer. A good starting point is to add 1 measure (50 ml) of spirit to 3 measures of mixer. Most spirits have an alcohol content of 37.5% . Using this as a guide, below is a useful ouitline of what the likley abv would be using different ratios.
Alcohol Mixer ABV
1 Unit 1 Unit 18.75%
1 Unit 2 Units 12.5%
1 Unit 3 Units 9.4%
1 Unit 4 Units 7.5%
1 Unit 5 Units 6.25%
If you are not drinking, 0.0% spirit works is a great alternative.
