An upstanding cylinder and a loading lid are produced respectively from glass. On the upper face of the bottom plate of the cylinder, a substance-pooling concave in which wine lees and tartar are pooled is formed. Owing to this constitution, there is little risk that the external air enters through a gap between the sliding faces of these members into the wine-pooling section in the cylinder and causes the oxidation of the wine. Since the cylinder comprises glass, the wine can be stored under almost the same conditions as in bottles. Further, sanitary precautions can be easily taken. Furthermore, problems such as the sticking of the cylinder to the loading lid due to stainless steel rust and so on can be overcome. |
