Definitions

  • This invention relates to a method and apparatus for oxygenating wine.
  • French Publication No. 2709983 discloses a method of micro-oxygenating wine held in tanks.
  • the technique is quite complex and requires careful control.
  • the technique involves injecting small bubbles of oxygen into the wine so that it will bubble through the wine so that some of the oxygen will be absorbed during the time in which the bubbles pass through the wine.
  • the object of the present invention is to provide an alternative method and apparatus which at least partially overcome the drawbacks noted above.
  • a method of oxygenating wine including the steps of: placing an oxygen supply tube in the wine to be oxygenated; supplying gas containing oxygen at a controlled pressure to the oxygen supply tube; and permitting the oxygen from the gas to permeate through the oxygen supply tube to dissolve into the wine.
  • the gas is substantially pure oxygen but it could be air.
  • the oxygen after the oxygen has permeated through the oxygen supply tube, it is directly dissolved into the wine and does not form bubbles in the fluid.
  • the method includes the step of supplying oxygen to an inlet end of the tube and the step of monitoring oxygen passing from an outlet end of the tube.
  • the monitoring includes the step of monitoring the pressure of the oxygen at the inlet and outlet ends of the tube whereby any leak in the tube can be detected.
  • the monitoring can include the step of detecting traces of the wine in the oxygen discharged from the outlet of the tube.
  • the pressure of the oxygen at the inlet end of the tube is in the range from 0 to 1000 kPa and preferably about 400 kPa.
  • the tube is made from a polymeric material.
  • the polymeric material is polytetrafluoroethylene (Teflon) or polydimethylsiloxane (Silastic).
  • the rate at which oxygen is dissolved into and reacted with the wine is in the range 1 to 100 millilitres per litre of wine per month.
  • the oxygen is first introduced into the wine after initial fermentation and prior to malolactic fermentation (MLF).
  • MLF normally occurs from two to four weeks after primary fermentation. After MLF has ceased, oxygenation can recommence and continue for a period typically in the range from one to six months.
  • the rate of supply of oxygen to the wine is decreased as a function of time in the oxygenation which takes place after MLF.
  • an apparatus for oxygenating wine including: an oxygen supply tube; means for mounting the supply tube in said wine, and gas supply means for supplying a gas containing oxygen at controlled pressure to the oxygen supply tube; and wherein the oxygen supply tube is permeable to oxygen, the arrangement being such that oxygen from the gas can permeate through the oxygen permeable tube to dissolve directly into the wine.
  • the means for mounting the supply tube in the wine includes couplings which permit an inlet end and an outlet end of the tube to be connected to a tank which holds the wine.
  • the apparatus includes control apparatus for controlling pressure of said gas at the inlet end of the tube.
  • the control means includes a pressure-monitoring device for monitoring the pressure at the outlet end of the tube.
  • the tube is formed from polymeric material such as polytetrafluoroethylene.
  • the wall thickness of the tube is in the range from 0.3 to 0.5mm and preferably about 0.3mm.
  • FIG. 1 is a schematic view of an oxygenating system embodying the principles of the invention
  • Figure 2 is a schematic view of a modified arrangement
  • FIG 3 is a schematic view of a barrel fitted with a bung device of the invention
  • Figure 4 is a side view of the bung device
  • Figure 5 is a schematic view of a preferred form of oxygenating system of the invention.
  • FIG. 6 is a schematic sectional view through the oxygenating module used in the system of Figure 5;
  • Figure 7 is a schematic cross-section through an oxygen permeable tube surrounded by a protective sheath.
  • FIG 1 diagrammatical ly illustrates an oxygenating system 2 for oxygenating wine 4 stored in a storage tank 6 which is typically made from stainless steel.
  • the tank 6 includes a removable cover 7 at the top of the tank.
  • the bottom 9 of the tank is also formed in a shallow conical shape.
  • the system includes an oxygen supply cylinder 8 which is coupled to an oxygen supply line 10.
  • the oxygen supply line 10 includes a pressure regulating valve 12 and monitoring apparatus 14.
  • the monitoring apparatus 14 may monitor a number of parameters including pressure, flow rate and may include sensors for impurities or the like.
  • the end of the line 10 is connected to an inlet coupling 16 which is preferably located in the cover 7 of the tank.
  • the system includes a tube 18 having an inlet end 20 which is connected to the inlet coupling 16.
  • the tube 18 is preferably formed from oxygen permeable material such as polytetrafluoroethylene.
  • the tube 18 preferably has an inside diameter of say 3mm and a wall thickness of 0.3mm and a length of 10m. This is suitable for oxygenation of wine where the capacity of the tank 6 is 4000 litres.
  • oxygen from the cylinder 8 is supplied to the inlet end 20 of the tube 18 at a controlled pressure so that it will permeate through the wall of the tube and be directly dissolved into the wine in which the tube is immersed, without formation of bubbles. It is possible to have the other end 22 of the tube closed so that all of the oxygen which flows into the tube eventually permeates therethrough. Whilst this arrangement would function, it is preferable to have the other end 22 of the tube connected to an outlet coupling 24 which in turn is connected to an oxygen outlet line 26.
  • the outlet coupling 24 is also located in the cover 7 of the tank. The location of the couplings 16 and 24 in the cover 7 minimises the possibility of wine leakage from the tank 6.
  • the line 26 includes a valve 30 to assist in maintaining pressure in system.
  • the outlet line 26 may include monitoring apparatus 28 for monitoring parameters such as pressure and composition of the gas flowing in the outlet line 26.
  • monitoring apparatus 28 By having the monitoring apparatus 28 provided, it is possible to monitor the differences in pressure in the supply line 10 and the outlet line 26. If there is a large pressure differential this could indicate that the tube 18 has ruptured or blocked which could cause spoiling of the wine by supplying excess or insufficient oxygen thereto.
  • the monitoring apparatus 14 and 28 can take the form of a single differential pressure unit which senses differences in pressure in the lines 10 and 26.
  • the monitoring apparatus may include sensors for sensing traces of wine in the line 26 which again would be indicative of leaks in the tube 18.
  • the flow rate for permeation of oxygen through the tube 18 is governed by the following formula:
  • ⁇ P is the pressure differential across the tube wall.
  • the pressure regulating valve 12 can be adjusted so as to provide the required pressure differential for a desired flow rate of oxygen into the wine.
  • the pressure of the oxygen in the supply line 10 would be in the range from 0 to 1000 kPa and more generally about 400 kPa, although this would also depend on the tube surface area and wall thickness.
  • the periods during which oxygenation takes place and the rates of oxygen flow into the wine are varied by the wine maker in accordance with individual preferences and the styles of wines which are to be produced.
  • MLF micro-oxygenation technique disclosed in the aforementioned French publication suggests that it is preferable to oxygenate the wine after primary fermentation has ceased but before the onset of MLF. After MLF ceases, a second period of oxygenation may occur at a rate which is comparable with the rate in the initial period but may be reduced as maturation continues.
  • the second period of treatment lasts from one to six months.
  • the tube 18 is somewhat fragile and susceptible to damage. Accordingly, it may be contained within a protective bag, sheath or container (not shown) which serves to protect the tube 18 from physical damage but does not substantially impede flow of wine and/or oxygen therethrough.
  • pure oxygen is supplied from the oxygen supply cylinder 8. It would, however, be possible to use other gases which contain oxygen. For instance, air could be supplied to the tube 18 but this would be less efficient because other components of the air, chiefly nitrogen gas, would also permeate through the tube 18. Thus a longer tube or higher supply pressure would be needed. Accordingly, it is preferred to use pure or substantially pure oxygen for supply to the tube 18.
  • FIG. 2 schematically illustrates a modified form of the invention.
  • a composite tube 32 is provided which can be operated so that it can vary the effective length thereof.
  • This is accomplished by having a second oxygen inlet line 34 coupled to the inlet end 36 of a second oxygen permeable tube 38, which is preferably made from the same material as the tube 18 but of a different length, say two to five times as long as the tube 18.
  • the outlet end 40 of the tube 38 is connected via a T-piece 42 to the inlet end 20 of the tube 18 via a check valve 41.
  • oxygen is supplied via the oxygen supply line 10 (and not through the second inlet line 34) so that oxygen flows through the tube 18 as before.
  • the check valve 41 prevents flow of oxygen into the second tube 38.
  • the composite tube 32 can be used in a second mode in which oxygen is supplied to the second oxygen inlet line 34 and not to the supply line 10 which would be closed. In this case the oxygen flows through the second tube 38 through the check valve 41 and T-piece 42 and then into the tube 18.
  • the effective length of the tube is much greater and hence the rate of oxygen absorption will be greater in the wine in which the composite tube 32 is immersed.
  • FIG 3 shows an oxygenating bung device 43 of the invention which is designed for use with a wine barrel 44.
  • the bung device 43 can be used where the wine is being stored in barrels rather than a large tank as in the case of Figure 1.
  • the bung device 43 includes a bung 45 which is initially of standard size and shape.
  • the bung 45 is made of silicone rubber and may have a narrow end of say 48mm and an upper end of 60mm, with a depth of about 55mm.
  • Two bores 46 and 47 are moulded in the bung 45.
  • the bores 46 and 47 snugly receive supply and return tubes 48 and 49 which are made from material which is impermeable to oxygen.
  • the tubes are made from nylon, polypropylene or other oxygen impermeable material.
  • the outer ends of the tubes are made from nylon, polypropylene or other oxygen impermeable material.
  • the oxygen permeable tube 18 is connected to the inner ends of the tubes 48 and 49, as shown in Figure 4. Couplings could be used to connect the ends of the tube 18 to the tubes 48 and 49. In the illustrated arrangement, however, the ends of the tube 18 are resiliently expanded so as to slide over and sealingly engage the ends of the tubes 48 and 49. This forms a suitable coupling.
  • the length of the tube 18 can be selected in accordance with the size of the barrel 44 and desired rate of oxygenation.
  • the tube 18 preferably has a diameter to wall thickness ratio of approximately 10: 1.
  • the tube 18 may be 8mm external diameter.
  • the tubes 48 and 49 preferably have the same external diameter as the tube 18. The length of the tubes 48 and
  • the length of the tube 18 can be adjusted in accordance with the volume of the barrel 44.
  • an oxygenation rate of say lOmls per litre per month can be achieved where the length of the tube 18 is 250mm when the supply tube 48 is supplied with air at atmospheric pressure.
  • An air pump or fan (not shown) can be coupled to the tube 48 or 49 in order to circulate air through the tube 18.
  • the rate of oxygenation can be increased by increasing the oxygen percentage in the feed gas supplied to the tube 48.
  • the rate of oxygenation can also be reduced by supplying less oxygen rich gases to the tube 48. This can be achieved by operating a feed pump (not shown) so that the supply of oxygen containing gas is varied as a function of time.
  • the combination of supply rate of oxygen containing gas and consumption rate of oxygen reduces the average oxygen concentration in the permeable tube.
  • FIG. 5 illustrates another oxygenating system of the invention.
  • the same reference numerals have been used to denote parts which are the same as or correspond to those of the previous embodiments.
  • the system includes an oxygen supply module 50 which is suspended in the storage tank 6 so that it is completely immersed in the wine 4.
  • the module 50 is located near the bottom of the tank.
  • the module 50 will normally be located about 200mm from the bottom of the tank so that it is clear of the lees which may accumulate in the bottom of the tank. Normally the module 50 would not be more than say one metre above the bottom of the tank.
  • the module 50 includes a loop 52 which enables it to be suspended by a line 54 which in turn is connected to the underside of the cover 7 of the tank 6.
  • the module 50 includes inlet and outlet connectors 56 and 58 which enable the module to be coupled to the inlet and outlet couplings 16 and 24 by means of inlet supply tubing 60 and outlet tubing 62.
  • the module 50 includes means for circulating the wine therethrough so that it flows over an oxygen permeable tube located inside the module. This enables the oxygen to be directly absorbed into the wine without forming bubbles.
  • the module includes a pump or impeller for circulating the wine through the module.
  • a container 63 in which can be located additives.
  • the additives may, for instance, comprise oak chips or other additives.
  • the container 63 can be formed from stainless steel mesh or other material which is inert to wine. It is disposed so that wine flows through the container 63 as wine flows to or from the module. This provides a very convenient way in which the wine can be treated with oak chips or other additives whilst the oxygenation is also taking place.
  • FIG 6 shows in part section in more detail a module 51 which can be used in the system shown in Figure 5.
  • the module 51 may also have a container (not shown in Figure 6) associated with it similar to the container 63 described above for holding oak chips or additives.
  • the module 51 includes a coil housing 70 which is formed by upper and lower disc members 72 and 74.
  • a perforated stainless steel mesh 76 extends between the disc members 72 and 74.
  • the oxygen tube 18 is formed into a helically wound coil 78 located within the housing 70.
  • the tube 18 functions in the same way as that of the previous embodiments and therefore need not be described in detail.
  • the convolutions of the coil 78 are held spaced from one another by means of a spacing grid (not shown) or radiantly extending baffles (not shown).
  • the lower disc member 74 includes a central inlet opening 80 which opens to an impeller chamber 82 in which is mounted an impeller 84.
  • the impeller 84 is rotated so as to draw wine through the opening 80 into the chamber 82 and then radially outwardly passing over the convolutions of the coil 78, the wine being expelled through an outlet defined by the perforated mesh 76. This ensures that there is good circulation of wine through the module 51 so that all of the wine in the tank 6 can be uniformly treated.
  • the impeller 84 is mounted on an impeller shaft 86, the lower end of which is supported by a lower bearing 88.
  • the lower bearing 88 can be integrally formed with disc member 74. This would be suitable in the case where the disc member 74 (as well as the disc member 72) were made from nylon. It would be possible, also, to provide a separate teflon insert (not shown) to serve as a bearing for the shaft 86.
  • the upper end of the shaft 86 is supported by means of a bearing 90.
  • the upper face of the impeller 84 is provided with a plurality of magnets 92 to enable magnetic coupling to a drive motor 94.
  • the motor 94 is located in a motor housing 96 which, generally speaking, is mounted centrally of the upper disc member 72.
  • the motor housing 96 includes a main block 98 having a cylindrical recess 100 therein in which the motor 94 is mounted.

  • the thickness of the wall 108 is preferably less than 2mm.
  • the bearing 90 can be integrally formed at the centre of the wall 108.
  • the housing 96 includes a cover 110 which is formed with a central tubular spigot 112.
  • the spigot 112 serves as an entrance point for the oxygen supply and return lines to the coil 78 as well as electric conductors for the motor 94.
  • the module 51 includes an oxygen supply line 1 14 which extends through bores provided in the cover 110 and main block 98 so as to be coupled to the inlet end 116 of the coil 78.

  • This material is thought to be strong enough to handle the internal pressure of the oxygen supplied to its inner bore. It is, however, somewhat prone to kinking which leads to fracture. Accordingly, it is inserted within a sheath 90 of oxygen permeable material which supports the tube 18 and makes it less susceptible to kinking.
  • the sheath 90 has an internal diameter of say 2mm and a wall thickness of say 0.05mm.
