a tubular through-screw portion that is attached by boring through the cork stopper;
a gas supply tube communicating with an inside of the through-screw portion;
a gas supply device attached to the gas supply tube and configured to supply a food additive gas to the gas supply tube;
a gate valve attached to the inside of the through-screw portion;
a tubular pouring portion, inserted in the through-screw portion, that passes through the gate valve; and
a check valve attached to an inside of the pouring portion,
wherein
the gate valve is configured to be opened by passing the pouring portion through the gate valve and to be closed by pulling the pouring portion out of the gate valve,
the pouring portion has a beverage supply hole formed at a lower end portion thereof,
the food additive gas supplied from the gas supply device is supplied from the gas supply tube to the through-screw portion and supplied to the internal space through a space between an outer wall of the pouring portion and an inner wall of the through-screw portion, and
the food additive gas supplied to the internal space exerts a pressing force that causes the beverage to flow to the inside of the pouring portion through the beverage supply hole, open the check valve, and be poured through an orifice of the pouring portion.
