Many bartenders mistakenly think that the alcohol content of cocktails is related to the glass used, but it is not. Calculating the alcohol content of cocktails has nothing to do with the capacity of the glass used. We should regard the total amount of materials used as 1, and then' convert the weight of various materials used into the number of ingredients, and multiply it by the alcohol content of the materials, and the final total is the alcohol content of cocktails. For example: Ginfizz 13.3% V/V gin 45 ml (45/135) x 40% v/v =13.3% v/v lemon juice 20 ml (20/135) x 0.

At that time, it was calculated without considering the melting amount of ice. In fact, this algorithm can't be 100% accurate, but as a bartender, you can know a glass of wine with each collocation, and you can probably guess the difference between the achievements in 1989 and 1989.
