At Snobby Duck, we value happiness, health, and prosperity. That's why Snobby Duck has created Project Blue Pearl. A foundation where a % of EVERY purchase goes directly into the Project Blue Pearl fund, dedicated to bringing fresh drinking water to those in need.

While Professor Mallard’s "unprecedented levels of snobbery" are satirical, actual water tasting notes are surprisingly complex and highly scientific. Real-world water sommeliers evaluate water based on three pillars: Total Dissolved Solids (TDS), mineral flavor profiles, and tactile mouthfeel. [1, 2, 3, 4, 5]

The exact breakdown of how professional water tasting notes work in the hospitality industry relies on specific sensory metrics.

  1. Total Dissolved Solids (TDS) & Weight

TDS measures the total concentration of dissolved minerals (in mg/L or ppm). This dictates the foundational weight and impact of the water on the palate. [1, 2, 3]

  • Low TDS (<50 mg/L): Described as light, airy, crisp, and neutral. It can sometimes taste slightly sweet or even "dry" because it rapidly strips minerals from your tongue. [1, 2, 3]
  • Medium TDS (50–400 mg/L): Described as balanced, classic, clean, and refreshing. This is the "sweet spot" for everyday drinking waters. [1, 2]
  • High TDS (>400 mg/L): Described as heavy, robust, savory, and thick
  1. Mineral Flavor Profiles

Just as grapes absorb flavors from vineyard soil, water absorbs flavors from underground rock strata. Sommeliers look for the following specific mineral indicators: [1, 2]

  • Calcium (Ca²⁺): Adds a milky, smooth, or chalky sensation. In high concentrations, it feels like biting into a piece of chalk and leaves a drying sensation.
  • Magnesium (Mg²⁺): Offers a complex duality. In lower amounts, it provides a refreshing, subtle sweetness. In high amounts, it tastes noticeably bitter, metallic, or medicinal.
  • Sodium (Na⁺): Contributes a soft, savory, or distinctly salty profile. It acts as a natural flavor enhancer on the tongue.
  • Bicarbonate (HCO₃⁻): Creates a crisp, alkaline, and refreshing taste. It acts as an acid neutralizer, yielding a very clean, structured finish.
  • Silica (SiO₂): Gives the water a distinctly slippery, velvety, or glassy mouthfeel, highly prized in volcanic waters. [1, 2, 3, 4, 5, 6, 7]
  1. Tactile Mouthfeel & Texture

Because water does not have strong aromatic volatile compounds, sommeliers heavily rely on "haptic sensations"—how the water physically feels inside the mouth. [1]

  • Silky/Velvety: Low-calcium, high-silica water that glides effortlessly across the tongue.
  • Structured/Hard: High-mineral limestone water that feels dense and rigid.
  • Effervescence (Carbonation): Real water tasting differentiates between artificial carbonation (aggressive, sharp, painful prickles) and natural carbonation (fine, creamy, persistent, and soft tiny bubbles). [1, 2, 3, 4, 5]
