Minimalist geometric coffee bean logo for artisan branding

Design a premium, minimalist flat logo for a specialty coffee brand, centered entirely around a stylized coffee bean. Create a unique, iconic mark using clean geometric shapes, refined curves, and clever negative space. The logo should feel timeless, elegant, and instantly recognizable, with a strong international branding aesthetic suitable for a modern artisan coffee shop. The coffee bean should be reimagined into a distinctive abstract symbol rather than a literal illustration, emphasizing simplicity, balance, and originality. Avoid overly decorative details and focus on creating a memorable brand mark that works at any size. Create 4–6 distinctly different logo concepts, each with a unique geometric interpretation of the coffee bean while maintaining the same premium minimalist branding style.
