From The Waste Lands:
Roland leaned over to Jake, who was sitting tailor-fashion near an oval bed of bright green flowers with Oy at his side. He Hurmured: "Drink only enough to be polite, Jake, or we'll be carrying you out of town - this is graf - strong apple-beer."
So, I may have botched the spelling (one "f", not two) but it certainly is referred to as an apple beer. Also - in the paragraph before the one I quoted, it's referred to as a "dark golden liquid," so for complete accuracy, you might wanna cut out a fair amount of the dark grains.
