Authenticity & The Artist
Every artwork tells a story.
At Sipit.art, every poster and painting is accompanied by a Certificate of Authenticity (COA), representing the creative vision, quality standards, and artistic identity behind the work.
Whether you are purchasing a detailed wine map, a contemporary poster, or a hand-painted artwork, the Certificate of Authenticity serves as a permanent record that your piece belongs to the official Sipit.art collection.
The Certificate of Authenticity
Every artwork includes its own Certificate of Authenticity (COA).
The certificate verifies the artwork’s origin and confirms that it is an authentic piece from the Sipit.art collection.
Each certificate contains:
- Artwork title
- Unique authenticity code
- Signature
- Date of issue
Our goal is simple: to provide collectors with confidence, transparency, and a lasting connection to the artwork they have chosen.
Meet Tau Northill
Tau Northill is the artistic identity behind many of the original artworks featured on Sipit.art.
His work is inspired by wine culture, gastronomy, travel, iconic destinations, design, and the moments that bring people together.
Blending creativity, storytelling, and visual simplicity, Tau Northill’s collections range from educational wine maps and tasting guides to contemporary wall art and hand-painted works.
Each piece begins with an idea. Sometimes that idea grows from extensive research and years of expertise. Other times it starts with a visual concept, a story worth telling, or an atmosphere worth capturing.
The result is artwork designed to be both visually engaging and meaningful — pieces that spark curiosity, conversation, and enjoyment.
Today, Tau Northill artworks can be found in homes, offices, wine cellars, tasting rooms, restaurants, and hospitality spaces around the world.
From Inspiration To Artwork
Every collection begins with a creative vision.
Some projects require significant research and development. Educational designs such as wine aroma maps, wine region maps, and tasting guides often represent hundreds of hours of study, refinement, and design work.
Other collections draw inspiration from architecture, travel, food culture, history, contemporary design, and everyday moments worth celebrating.
Modern creative tools may be used throughout the artistic process, including digital illustration software and artificial intelligence. These tools help transform ideas into finished artworks while maintaining a consistent artistic vision and high design standards.
Every artwork released under the Tau Northill name is carefully reviewed and refined before becoming part of the Sipit.art collection.
Hand-Painted Artworks
Selected Tau Northill designs are also available as hand-painted artworks.
These paintings are created from original Tau Northill concepts and compositions, transforming artistic visions into unique pieces intended to bring character and atmosphere into a space.
Each artwork follows the creative direction, composition, and aesthetic principles that define the Tau Northill collections.
The combination of artistic vision, craftsmanship, and attention to detail ensures that every painting remains faithful to the spirit of the original work.
