Have a Drink

Funny post on German blog “Trinklaune” by Robin Stein. He suggests using Sankey diagrams to control loss of spirits in a pub. Apparently this was kind of a student project.

Here we see the Sankey diagram for a Negroni cocktail made up from equal parts of Gin, Campari and Vermouth rosso.

On every bottle a certain quantity is lost. This is probably because bartenders put in more spirit than they should, or offer free drinks, or maybe just drink it themselves…

As we can see in this figure, losses can add up considerably in a bar that serves several drinks.
