Gravitation tap-useful device for filling in bottles. Thanks to it we can control the amount of poured in beer or wine. We connect the valve with an adaptor (included) with the tap. Next put it in the bottle and start pouring. Thanks to it there is no foaming and we can fill in the bottle to needed level. When the bottle is full just lower the bottle and the valve will automatically close the flow.
CAUTION!
Every country has its own legal regulations governing the

non-compliance.
