An apparatus for aging a liquid in a container includes: an elongated bung having a top and a bottom, the bottom having a male or female connector; and an elongated wooden piece having a longitudinal axis, an upper end, a lower end, and a side, the upper end having a male or female connector adapted to connect to the male or female connector of the bottom of the elongated bung, whereby the elongated bung and the elongated wooden piece are removably connected by connecting the male or female connector of the bottom of the elongated bung with the male or female connector of the upper end of the elongated wooden piece. The bung may have a first opening, a side with another opening, the first opening being fluidly connected to the another opening by a pathway adapted to transmit a gas from the container through the first opening.

An automatic apparatus for regulating and controlling the level of a liquid (1) in a tank (2) includes a liquid level detector (8). A vessel (3) associated with the tank (2) has a predetermined volume and is equipped with an upper closure (6) and with an open bottom (5) in communication with the interior of the tank (2) at a height below the level of the liquid (1). The automatic apparatus increases/decreases a liquid-free portion of the volume inside the vessel (3) and consequently transfers part of the liquid to/from the tank (2) through the bottom (5) in response to changes in the liquid level inside the tank (2) as detected by the liquid level detector (8).

A method for processing, in a container, a vegetable product containing a solid part suspended in a liquid part, comprises controlling the pressure of a gas in said container for modifying the specific weight of said solid part, so as to prevent said solid part from floating on said liquid part until drying; an apparatus comprises a timing device arranged for opening and/or closing, in a cyclical manner, a venting arrangement comprised in an operating chamber of a vinifying apparatus, so as to alternatively make said operating chamber communicate with an external environment and/or separate said operating chamber from said external environment and consequently decrease and/or increase a pressure of a gas in said operating chamber.
