Barrel
Modern wooden barrels for wine-making are made of French common oak (Quercus robur), white oak (Quercus petraea), or American white oak (Quercus alba) and typically have standard sizes: "Bordeaux type" 225 litres (59 US gal; 49 imp gal), "Burgundy type" 228 litres (60 US gal; 50 imp gal) and "Cognac type" 300 litres (79 US gal; 66 imp gal). Modern barrels and casks can also be made of aluminum, stainless steel, and different types of plastic, such as HDPE.
