Abstract

System for maturation of wine comprises a tank and one or more wooden barrels and flow connectors to allow circulation of maturing wine between the tank and the one or more barrels. The barrels may comprise a wooden exterior and an internal volume and a plurality of internal wooden surfaces extending inwardly of the wooden exterior into the internal volume to increase wood surface area. The barrel may be a traditional oak barrel.

First claim

What is claimed is:

1. System for maturation of wine comprising a tank, wine and at least one wooden barrel and flow connectors to allow circulation of maturing wine between said tank and said at least one barrel, wherein said wooden barrel comprises:
a barrel inlet;
a barrel outlet;
internal wooden surfaces, said internal wooden surfaces located to obstruct flow between said barrel inlet and said barrel outlet, said internal wooden surfaces forming a succession of respectively closed-off compartments;
openings in said internal wooden surfaces located between said respectively closed-off compartments, said openings being located at alternating ends of succeeding compartments respectively, thereby to define a zig-zag flow path, for the wine, from the barrel inlet, through lengths of said succeeding compartments respectively and to the barrel outlet, the flow path to limit said circulation of said maturing wine to pass through said each of said compartments and back to said tank.

2. The system of claim 1 , wherein said tank is a steel tank.

3. The system of claim 1 , wherein the at least one barrel is at a lower level than a top of said tank to allow gravity to assist said circulation.

4. The system of claim 1 , wherein the flow connectors comprise a pump to assist said circulation.

5. The system of claim 1 , comprising a plurality of barrels connected in series with each other and with said tank.

6. The system of claim 1 , comprising a plurality of barrels connected in parallel with each other and in series with said tank.

7. A barrel for maturation of wine comprising a wooden exterior and an internal volume and a plurality of internal wooden surfaces extending inwardly of said wooden exterior into said internal volume, wherein said internal wooden surfaces divide said barrel into respectively closed-off compartments, said internal wooden surfaces having openings at alternating ends of successive respectively closed-off compartments to allow for flow of maturing wine to travel through each of said compartments in succession, the barrel being placed on its side and wherein said compartments and said openings form a zig-zag flow path between an intake at one end of said barrel and an outlet at an opposite end of said barrel, the flow path being via lengths of said succeeding compartments, said intake and said outlet configured for connecting to an external tank, thereby to limit circulation from said external tank to follow said compartments along said zig-zag flow path and back to said external tank, the barrel being connected to a tank via flow connectors, said flow connectors configured with said tank and said barrel such that wine flows from an upper part of a lower third of the tank via a wine outlet of said tank by gravitation, into the barrel, circulates through said barrel and returns to an upper part of the tank via a wine inlet of said tank.

8. The barrel of claim 7 , comprising oak.

9. The barrel of claim 7 , wherein said inlet is higher than said outlet, thereby to allow gravity to assist with flow of said maturing wine through said flow path.

10. A method of maturing wine comprising circulating maturing wine between at least one wooden barrel and a tank, the wooden barrel having internal walls forming respectively isolated compartments and openings between said compartments, the openings being at alternating ends of succeeding compartments to force said circulating wine into a zig-zag flow path through succeeding lengths of said compartments, said circulating comprising following said flow path through said compartments of said barrel and returning to said tank via flow connectors, said flow connectors configured with said tank and said barrel such that wine flows from an upper part of a lower third of the tank via a wine outlet of said tank by gravitation, into the barrel, circulates through said barrel and returns to an upper part of the tank via a wine inlet of said tank.

11. The method of claim 10 , wherein circulation is sufficiently slow to allow sedimentation from said maturing wine within said tank.
