}Explanation
US cups convert to grams by multiplying with the verified 235.2 g/cup density derived from the US cup (236.588 mL) definition and the liquid’s grams-per-milliliter ratio.
Use the calculator to translate recipe cups into grams while keeping the same density that powers the milliliter and fluid ounce families.
Port is a fortified wine produced in Portugal’s Douro Valley, known for its rich sweetness, dark-fruit character, and elevated alcohol. Practical use: Port is used as a sweet fortified wine to add richness, sweetness, and dark-fruit depth. It increases body and alcoholic warmth in mixed builds, supports dessert-oriented compositions, and can also be enjoyed on its own as a classic after-dinner fortified wine. Composition and sensory context: Port delivers a dense, sweet fortified-wine profile dominated by ripe dark fruit, rich residual sugar, and noticeable alcoholic warmth. Spice and cocoa-like nuances can appear depending on style and aging, while acidity remains supportive rather than sharp. Compared to Madeira, Port is generally less acidic and more fruit-driven; compared to oxidatively aged sherries, it is richer and sweeter with a more direct dark-fruit core.
Port uses 0.994 g/mL in this dataset. That makes it 0.6% lighter by volume than water at the 1 g/mL reference. On the same basis, one US cup is about 235.2 g and one US fluid ounce is about 29.4 g.
Alcohol and residual sugar vary by style, so the reference is best treated as a representative wine value rather than a producer specification. These figures describe a reference conversion, not a guarantee for every brand, recipe, serving temperature, or production batch.
Evidence status for Port: medium-confidence. Dataset note: Wine/Vermouth density approximation near room temperature using a unified wine rule.

Methodology
Port density evidence
Port uses 0.994 g/mL in this dataset. Confidence: medium. Source basis: Wine/Vermouth density approximation near room temperature using a unified wine rule.
Evidence status: reference-recorded. The source note is recorded; this does not certify every preparation or measurement condition.
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.
