Full API documentation

Explanation

Convert US fluid ounces of red wine to grams using a density reference of 0.995 g/mL. On that basis, 1 US fluid ounce works out to 29.43 grams for this ingredient.

That is useful for aperitif pours, fortified wine measures, and dessert or sauce prep where red wine starts as a liquid measure but needs a matching weight. Red wine can shift a little with sugar level, ABV, and style, so the converter keeps one consistent profile for repeatable kitchen or bar use.

Method & Density Basis

Density basis: 0.995 g/mL (anchored to US cup 236.588 mL and US fl oz 29.57 mL).
Applied factor: 1 Fluid Ounce = 29.43 Grams.
Consistency rule: mirror pages invert the same per-liquid constants so forward and reverse directions remain aligned.

Methodology

Red wine density evidence

Red Wine is an alcoholic beverage made from fermented dark-skinned grapes, valued for its fruit depth, tannic structure, and wide stylistic range.

Practical use: Red wine is used as a still wine base to add acidity, tannic structure, and dark-fruit depth. It contributes body and complexity in wine-based mixed serves and is widely used in cooking to add savory richness, acidity, and aromatic depth to sauces, braises, and reductions.

Composition and sensory context: Red wine generally presents a dry, fruit-driven profile supported by tannins and varying acidity, with notes that can range from fresh berry and plum to earthy, spicy, and oak-influenced nuances. Sweetness is typically low, while bitterness is expressed as phenolic grip rather than aromatic bitterness. Because style depends on grape variety, region, and aging, red wine can move from light and bright to dense and highly structured, but it consistently contributes depth, acidity, and texture.

Red wine uses 0.995 g/mL in this dataset, which is close to the 1 g/mL water reference. Evidence status: medium-confidence. Source basis: Red wine density estimate.

Among the 23 reviewed records labeled Wines & Fortified Wines, the nearest density to Red wine is Cocchi Americano at 0.994 g/mL: an absolute difference of 0.001 g/mL (0.1% relative to Red wine). The observed range in this labeled group is Cocchi Americano at 0.994 g/mL to Red wine at 0.995 g/mL. This is a numerical comparison, not a claim that the liquids are interchangeable.

Brand formulation, alcohol or sugar concentration, carbonation, and serving temperature can change the weight of a measured volume. Use this value as a documented reference rather than a producer specification.
