How to Use Coffee Grounds and Stains for Art

Ever wondered if your morning coffee could be more than just a drink? What if your leftover coffee stains or used cups could become tools for creating striking artwork? That’s exactly what one artist decided to explore — turning the everyday act of drinking coffee into a medium for visual expression.

Yes, coffee can be used to create detailed artworks — like a portrait of Jay Chou made entirely from stacked coffee cup-bottom imprints and coffee stains. Artist Kang Yi uses no paintbrushes, relying solely on the natural pigments and shapes formed by coffee to form her pieces.

Who Is Artist Kang Yi?

Kang Yi, also known as Red, is a Malaysian-Chinese visual artist currently based in Shanghai. On her blog, she describes herself as “an artist who likes to paint, but without a paintbrush.” Her work avoids traditional brushes, instead using unconventional materials and methods to produce bold imagery. This project showcases her talent in transforming a simple coffee stain into fine art.

The Jay Chou Coffee Art Portrait

Inspired by the atmosphere and aesthetics of Jay Chou’s film Secret (), Kang Yi crafted a portrait of the musician using only the bottoms of coffee cups and the stains they leave behind. Each image is formed by carefully layering repeated impressions from the circular base of a coffee cup. The resulting piece vividly captures Jay Chou’s likeness through nothing but the natural shape and tone of coffee residue.

How Coffee Cup Bottoms Create Art

Kang Yi’s technique involves pressing the bottom of a coffee cup — still bearing a ring of brewed coffee — onto paper repeatedly. By aligning and layering these imprints, she builds up tonal depth, contrast, and detail. The coffee stains provide both color and texture, eliminating the need for any additional medium. The circular imprints mimic brush strokes or pixels, allowing for surprisingly intricate results.

Why Use Coffee Instead of Paint?

Using coffee as a medium offers several unique advantages. First, it’s an everyday material with an organic, warm tone that lends itself well to portraiture. Second, the natural variation in staining — depending on brew strength, cup size, and drying time — introduces subtle inconsistencies that add character. Most importantly, it challenges conventional ideas of painting by removing the brush entirely, shifting focus to imprint, layering, and arrangement.
