Mixology is becoming an increasingly complex art, but according to bartenders it’s the classic cocktails that keep customers coming back.

Drinks International has released its annual list of the world’s best-selling classic cocktails in its January issue. 

DI asked bartenders from 127 of the best bars in 38 countries around the world – all of which have won or been nominated for global awards over the past year – to rank their 10 best-selling cocktails.

Coming out at No.1 for the fifth year in a row was the Old Fashioned. This classic is made by muddling a sugar cube with Angostura bitters, then adding bourbon or rye, a few dashes of water, and finishing it with a citrus rind.

Among the newly popular drinks filtering into the list was the Aperol Spritz, which joined the top 10 for the first time at No.9. 

Drinks International notes: “What happens here among bar-world influencers trickles down to the mainstream. The average Joe didn’t just one day suddenly decide that he had a penchant for Negronis – it’s a process. So producers might take note – these classic cocktails have the power to propel both brand and category.”

Here’s the top 10:

1. Old Fashioned
2. Negroni
3. Whiskey Sour
4. Daiquiri
5. Manhattan
6. Dry Martini
7. Espresso Martini
8. Margarita
9. Aperol Spritz
10. Moscow Mule
