"Grindable, but not pepper, quirky": Coffee beans are commonly ground to make coffee grounds, similar to how pepper is ground for seasoning. The line adds a playful twist by mentioning that it's not referring to pepper.

"Pressing's an option, no button's plea": This refers to the process of making coffee using a French press, where coffee grounds are steeped in hot water and then pressed down. It clarifies that while pressing is involved, it's not about pressing a button.

"Brewing's my game, not beer, agree?": Coffee is brewed to make the beverage we enjoy, but here it clarifies that it's not referring to brewing beer.

"A bean, not magic, plain to see": Coffee comes from coffee beans, but the riddle emphasizes that despite being a bean, it's not magical in nature.
