Explore the differences between Arabica, Robusta, Liberica, and Excelsa coffee beans—including size, shape, processing methods, and internal anatomy.

If you’ve ever held a bag of green or roasted coffee beans and wondered why some are small and oval, others large and round, or how processing changes their final form, you’re not alone. These physical differences aren’t just visual—they relate directly to the plant species, growing conditions, and production steps that define each bean’s identity. Let’s break down the key types, traits, and processes that shape the coffee beans we roast and brew.
