Fermented milk will typically look thicker and have a slightly tangy or sour taste compared to fresh milk. The color of fermented milk can vary depending on what type of bacteria are used in the fermentation process, but it is often slightly off-white or yellowish in color. The texture of fermented milk might also be slightly lumpy or grainy due to the formation of curds during fermentation. Overall, fermented milk will have a different appearance than fresh milk and might be more similar in texture to yogurt.
