Water to Wine: Coloring Sheet Collection
The water to wine color sheet, often referred to as a color transition sheet, is an indispensable tool in the wine industry, helping to standardized and facilitate accurate communication among winemakers, sales teams, and consumers. This sheet bridges the gap between the relatively clear starting point of water and the rich, complex hues of wine, providing a user-friendly visual reference for color analysis.
Understanding the complexities of wine color can be challenging, as it's influenced by a myriad of factors such as grape variety, soil type, climate, vinification methods, and aging processes. The water to wine color sheet simplifies this process, offering a practical, visual guide that transcends language barriers, making it universally applicable across regions and cultures.
Understanding Wine Color Scales
The primary wine color scales are those developed by the International Organisation of Vine and Wine (OIV) and the University of California, Davis (UCD). Both scales use color mitts, which are color measurement tools based on human perception, but they differ in the number of color categories and the specific hues represented.
This section will focus on the OIV scale, which ranges from 0 (water white) to 7 (deep red), as it's widely used and accepted internationally. The UCD scale, which ranges from 1 (pale straw) to 18 (dark red), will be briefly discussed later under the

subtopic.
OIV Wine Color Scale
The OIV wine color scale provides a clear progression from pale to deep hues, with each category represented by a specific L*a*b* color value. L* represents lightness, while a* and b* represent the red-green and yellow-blue color axes, respectively. This standardized approach ensures consistency and makes it easy to communicate color using numbers.
For instance, a white wine with an OIV color scale of 2 might have an L*a*b* value of approximately 83.2, -0.5, and 6.7. This corresponds to a pale to medium yellow hue, with a slight greenish tint. Compare this to a red wine with an OIV color of 5, which could have an L*a*b* value of around 35.5, 16.3, and 2.5, indicating a vibrant, ruby red color.
Using the Water to Wine Color Sheet
The water to wine color sheet typically features a series of vertical columns representing the OIV or UCD scale, with corresponding color patches for each category. Horizontal rows may display different levels of color intensity, L*, within each category. This visual representation makes it easy to match a wine's color to its corresponding scale number, or vice versa.
To use the sheet, simply look for the column that most closely matches the wine's color. The corresponding OIV or UCD number provides an objective measure of the wine's color. This number can then be used to communicate the wine's color to others, making it invaluable for winemakers, sales teams, and sommeliers.
Other Factors Influencing Wine Color
While the water to wine color sheet is a powerful tool, it's essential to consider other factors that can impact a wine's color and the way it appears.
Wine's color can be influenced by various aspects, including the wine's age, its alcoholic strength, and the container it's stored in. For example, older wines tend to develop deeper, more amber hues due to chemotropic polymerization and oxidation. Higher alcohol content can also darken a wine's color, as can exposure to light and heat.
Wine Aging and Color Evolution
Wine's color can change significantly over time, with white wines typically developing deeper golden hues, while red wines may become more brick-red or brown. This evolution is influenced by numerous factors, including the wine's composition, its storage conditions, and its age.
For instance, a white wine may start as a pale straw color at 0 on the OIV scale but, after a decade in the bottle, could develop a rich gold hue closer to 4 or 5 on the OIV scale. Similarly, a red wine may begin as a vibrant ruby color at 4 on the OIV scale, maturing to a more evolved tawny hue at around 6 or 7 on the OIV scale after extended aging.
Other Wine Color Scales
As mentioned earlier, the UCD wine color scale is an alternative to the OIV scale. It features a broader range of color categories, from pale straw (1) to dark red (18). Some winemakers and organizations prefer this scale for its increased resolution, but it's less widely used internationally.
Another less common scale is the Louise subtypes scale, which was developed by the Australian wine industry. It provides a more detailed breakdown of the OIV colors, splitting them into multiple subtypes. For example, it further details the OIV category 3 (light yellow), breaking it down into subtypes A (light) and B (deep). This scale is particularly useful for those working with Australian wines but may not be as familiar to international consumers or winemakers.
The water to wine color sheet is a vital tool for understanding and communicating wine color effectively. By referencing the OIV or UCD scale, winemakers, sales teams, and consumers can accurately describe and compare wines, transcending language barriers and enhancing the overall wine experience.
