Le Petit Calon is a limited-edition red Bordeaux blend produced by Château Calon Ségur from the Saint-Estèphe appellation in the Médoc region of Bordeaux, France. The wine is crafted from the youngest vine parcels within the 55-hectare Calon Ségur estate, with vines averaging 22 years of age planted at a density of 8,000 vines per hectare.

The blend comprises 53% Cabernet Sauvignon, 38% Merlot, 7% Cabernet Franc, and 2% Petit Verdot, grown on deep Quaternary gravel soils with clay sub-soil from the Tertiary Period. Grapes are harvested by hand with an initial selection on the vine, followed by mechanical vibration sorting and a second hand sort. Vinification takes place in temperature-controlled conical stainless-steel tanks with maceration lasting 18 to 21 days, pump-overs twice daily, and fermentation at 26°C. Malolactic fermentation is completed in stainless steel using indigenous lactic bacteria. The wine is aged 15 months in one-wine barrels and fined with egg white. Consulting oenologist Éric Boissenot oversees production. This wine was produced as a limited edition between 2015 and 2018.
