In Dex's diner (in Attack of the Clones) Obi-Wan drinks a beverage called "Jawa Juice", identified in the film's official novelisation as "Ardees".
With great effort, Dexter managed to squeeze himself into the seat opposite Obi-Wan. The waitress droid was back by then, setting two steaming mugs of ardees in front of the old friends.
We learn in the short story "Born in the Storm" that Jawa juice is alcoholic
So we geared up, rolled out, and there we were in the heart of Mos Eisley, getting crispy beneath all those layers of armor and this giant black bodysock, and quite frankly craving a thirst quencher, and I don’t mean the kind that actually quenches thirst. I mean the kind that dehydrates, in fact. A beverage, specifically one that frizzles, to be precise. Jawa juice, in case I wasn’t clear. I wanted a damn drink.
The fully canon Star Wars: Absolutely Everything You Need to Know factbook also confirms that ardees contains fermented grains, indicating that it's an alcoholic beverage.
