Many bartenders teach themselves to mix drinks, or learn on the job. Aspiring bartenders have the option of going to bartending school to obtain a state-issued license, but few states require certification and drink standards vary from bar to bar.
The best way to become a bartender is through experience. Bartender Kenji Magrann-Wells previously told Business Insider that new bartenders must get experience before getting into large venues. Many bartenders start as waiters or bartending assistants before getting a gig themselves.
"Experience is key, especially when going for the giant mega-clubs where the atmosphere is tense and the payout is ridiculous," Magrann-Well said. "So take the jobs where you can get them."
