}Explanation
Port grams convert to cups by dividing through the verified 235.168 g/cup density anchored to the US cup (236.588 mL) definition.
Use the calculator to see how labeled weights translate into cups using the same density as the milliliter family.
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.
