Pink Gin is a cocktail – one of the foundational beverages of the British Empire. It is, as Bond notes, gin with bitters. Some put the bitters directly into the gin, others put the bitters into the glass, swirl it around, dump them out and add the gin.

The Schweppes Bitter Lemon being consumed by Hendriks is a non-alcoholic soft drink. It is a flavored tonic water which has never been hugely popular in the United States, but was and is in Europe.
