Risotto is one of the most rewarding dishes in Italian cuisine, but it requires precise ratios and constant attention. The Risotto Portion Calculator provides exact quantities of rice, stock, wine, and butter for the classic mantecatura finish, scaling perfectly for any number of diners whether you are making a quiet dinner for two or a large gathering for thirty.
The three classic risotto rices are Arborio, Carnaroli, and Vialone Nano, each with distinct properties. Arborio is the most widely available and has a high starch content, producing a very creamy result. Carnaroli is considered the 'king of risotto rices' by many Italian chefs — it holds its shape slightly better than Arborio and releases starch more gradually, giving more control over the final texture. Vialone Nano absorbs more liquid than the other two (hence a higher stock ratio in the calculator), producing a looser, almost soup-like risotto preferred in the Veneto tradition.
For a main course (primo piatto in the Italian tradition), 80–90 grams of dry rice per person is the standard. As a starter, 60 grams suffices. As a side dish accompanying meat or fish, 50 grams is appropriate. These quantities seem modest but expand significantly as rice absorbs stock — each gram of dry Arborio absorbs approximately 3.5–4 times its weight in liquid during the 18–20 minutes of gradual stock addition.
The stock ratio is critical. Traditional risotto requires approximately 4 times the weight of rice in warm stock, added ladle by ladle throughout cooking. The stock must be kept warm (not boiling) at a separate simmer to avoid shocking the rice with cold liquid, which would interrupt the starch release. Using cold stock is one of the most common mistakes amateur risotto cooks make.
Wine is added after the initial toasting (tostatura) of the rice. About 80ml per 100g of rice is standard — enough to deglaze, add acidity, and begin the cooking process. Use a dry white wine like Pinot Grigio or Sauvignon Blanc, or a dry white vermouth.
The butter quantity shown is for the final mantecatura — the vigorous off-heat stirring with cold butter (and usually grated Parmigiano Reggiano) that creates the characteristic creamy emulsion. This step is non-negotiable in classic risotto.
Rice per person: 60g (starter), 90g (main), 50g (side). Total rice × 4.0 (Arborio/Carnaroli) or × 4.5 (Vialone Nano) ÷ 1000 = stock in liters. Wine = 0.8ml per gram of rice. Butter for mantecatura = 12% of rice weight.
Have all stock warm and ready before starting. The stock figure accounts for both absorption and some evaporation. If your finished risotto is too thick, add a final ladle of stock before the mantecatura. If too loose, cook one extra minute uncovered. Wine quantity can be reduced for a milder flavor profile.

4 × 90g = 360g Arborio. Stock: 360 × 4 = 1440ml ≈ 1.4L. Wine: 288ml (roughly one glass). Butter: 43g for mantecatura.

6 × 60g = 360g Vialone Nano. Higher stock ratio: 360 × 4.5 = 1620ml ≈ 1.6L for the looser Venetian style.
Carnaroli is widely considered the gold standard due to its balanced starch release and structural integrity. Arborio is more available and also excellent. Vialone Nano produces a looser, creamier result favored in northeastern Italy.
Plan for 4 times the weight of dry rice in stock, approximately 360–400ml per main-course serving. Vialone Nano absorbs even more, requiring 4.5 times its weight. Always have slightly more warm stock ready than you think you will need.
No. Rinsing removes surface starch, which is precisely what creates risotto's creamy texture. Add dry rice directly to the pan after toasting the shallots and without washing.
Tostatura is the toasting step where dry rice is added to the hot pan (with shallots and butter or oil) and stirred for 1–2 minutes until the grains become translucent at the edges. This seals the outer starch layer slightly, allowing the rice to absorb stock more gradually and maintain structure.
Mantecatura is the final off-heat step where cold butter (and often grated Parmesan) is beaten vigorously into the cooked risotto. This creates a stable emulsion with the released starch, producing the characteristic creamy, glossy finish that defines great risotto.
Risotto does not hold well. For restaurants, chefs partially cook risotto (all'onda stage) and finish it to order. At home, cook risotto fully just before serving. If you must prep ahead, cook to 80% doneness, spread on a baking sheet to stop cooking, then reheat in a pan with warm stock to order.
From the first ladle of stock, plan for 18–22 minutes of constant stirring and gradual stock addition. The total time including sauteing shallots and toasting rice is typically 25–30 minutes.
A dry white wine works best — Pinot Grigio, Sauvignon Blanc, Vermentino, or dry white vermouth are all excellent. Avoid oaked Chardonnay, which can add a bitter flavor. Use wine you would be happy drinking.
Perfectly cooked risotto should flow like slow lava when the pan is shaken — the Italian term is all'onda (like a wave). It should not be stiff and clumped nor watery and soup-like. Each grain should be tender but retain a tiny bite at the very center.
Yes. Replace wine with an equal volume of warm stock and add a small splash of lemon juice to provide the acidity that wine normally contributes. The result is slightly less complex but still delicious.
