• Versatile, this product can be used with any type of CIP or pump circulatory spray cleaning maintenancesystem and with manual brush or cloth cleaning.

• When used at the suggested dose rate, it has low to moderate foaming properties, allowing for easierpumping of prepared solutions.

• Quickly removes wine tartar, colour and protein from wine contact surfaces in a hot aqueous solution.Leaves oak timber retaining its natural odour style and colour without charring it.

• Improves hygiene quality in oak vessels by thoroughly removing and rinsing organic solids that contributeto bacteria growth.

• When in a cleaning solution, in a circulatory CIP system in oak vats and barrels, it is non-charring totimber, and non-corrosive to metal bands and painted surfaces with occasional contact.

• This product will not establish secondary cleaning regimes by causing residual protein char-stain ontimber interior surfaces. Any surface foam is quickly dispersed during the water rinse cycle.

• All surfaces are clean, spot and streak-free, free of chloride residue, odourless and pH neutral after theclean water rinse following the cleaning cycle, eliminating any potential for taint of wine in oak storage.

• Any small amounts of aqueous residues remaining in barrels after the cleaning process will not taint wine.(Ref. Controlled trial with BRL Hardy/Constellation),

Product Information

Historical hygiene methods the cause of wine quality issues from contact with defectiveoak surfaces

For many years winemakers were taught not to use any cleaning chemicals inside their barrels for fear ofestablishing potentially wine-tainting conditions if any residues remained on or in the internal oak surfaces. Therecommended method was to “only rinse each barrel with water to remove wine soils”. The problem was thatthe short term contact time of the cold water cleaning method as promoted, may not have fully removed muchof the tartar and wine soils resident on the internal surfaces of the oak.The application of this method prevented the best outcome for good hygiene inside the barrel.In many barrels, tartar was still present and much organic wine soil fines were still fast in the pores, under anyblisters and other imperfections of the internal oak surface, even though, particularly in the case of white wine,most of the ‘colour’ was not present.

This method led to a greater incidence of reported acetic conditions or volatile acid (VA) in many oak vesselslikely due to an over-population of bacteria present beneath the non-removed wine solids, ultimately affectingwine quality.

To achieve much cleaner oak surfaces and therefore better hygiene, a more effective cleaning product andmethod was required to reduce or eliminate the conditions for wine spoilage.This was one of the main reasons for us to develop our Oak Restorers, and also from a request to clean oakstaves without leaching flavour, so they could be viably re-used many times.

Cleaning method options

Pressure WashingOne method is to use Oak Restorer HWF in an aqueous solution with a barrel internal circulation-CIP pressurewashing system which entails using a high pressure fixed or revolving spray-nozzle at the top of a stainlesssteel tubular spear supplied by a flexible hose delivery pipe from the pump draw from an open-head collectorbath below the barrel bung opening whilst the barrel is stationary on a ‘cradle’.Do not use the same minimum, set time for each barrel, but apply time to thoroughly clean each barrel accordingto wine-soil deposits. This will mean an inspection of the barrel during the cleaning process to see that theinterior surfaces are being thoroughly cleaned.

As part our research, Oak Restorer HWF was performance tested on-site at a well established corporate wineryfor its cleaning ability in a fixed 2-minute schedule cleaning time under high pressure spray on both Americanand French oak.The barrels were also not water rinsed to determine whether Oak Restorer HWF residues would taint wine.Once cleaned, the barrels were stored with the barrel opening facing downward on timber rails for a time toallow the cleaning solution to drain. The barrels were then re-filled with wine and tested for quality some 12 -18 months later.The wine specification was reported to us as unaffected in any way by any Oak Restorer residue.

Oak BathAn alternative method for oak barrels which can be adopted if there is no on-site pressure washing facility isto fill each barrel and bathe-soak the internals with a cleaning solution over a 24-48 hour period. This method,whilst taking a longer time, consumes less generated power and allows the buffered alkaline time to effervesceto deep clean the pores of the timber, neutralise wine acids and deodorise the barrel more thoroughly.

Disinfecting oak surfaces before refillingRefer to our products Porocide and Peroxipure OFG and the hygiene procedures.

Directions for use

PRE-COMMENCEMENT INFORMATION

Cleaning cycle timingThe best time to clean your oak barrel or vat internal surfaces is when the wine acid tartar and soils are stilldamp, but not cold. The tartar crystals are still in a state of hydration, and the crystal structure then is at its“softest”.By cleaning at this time you will use less chemical to breakdown the tartar crystal, and the vessel will take lesstime to clean. If you delay the cleaning process, you will have an increased bacteria load as well as a potentialrisk for other airborne, non-wine soils to be resident in the vessel if the vessel is left unsealed.

WaterRain water is the optimum for use, otherwise de-chlorinated potable water.Bore and ‘hard’ water may demand more chemical.The volume of water required will be set by the size of the oak barrel or vat, the surface area to be cleaned,the quantity of wine-soil present, the quantity of water needed in flexible hose-lines for maintaining a primedpump. For heavy loads of accumulated tartar, more water will generally increase cleaning efficiency.For barrels: 100-150L of water for CIP.For large vats: 200-400L of water for CIP.

Water temperatureThe cleaning solution temperature range recommended for Oak Restorer HWF is 40-60°C.Using this temperature range will reduce the cleaning time. Oak Restorer HWF is soluble in hot water to about12% w/v. If this product is used with cold water (10-20°C) it will extend the cleaning time and be more chemicallydemanding.

Chemical dosage rateDepending on soil load, use Oak Restorer HWF in the range of 0.5 – 2.0kg/100L of clean water(0.5 - 2.0% w/v). Oak Restorer HWF can also be manually used in a hot aqueous solution with a brush, non-scratch scourer or cloth on oak timber external surfaces.

Water pressure and spray equipmentOak Restorer HWF is compatible with all pressure spray equipment.Higher water pressure from the spray ball, with greater solution wash volumes down the sides of the barrel orvat will accelerate and improve the cleaning process. Re-positioning the spray ball to the location of the soilduring the cleaning cycle in larger vats will accelerate the cleaning process. With large vats, it is recommendedthat a sampling of cleaning solution be taken regularly during the cleaning process for a pH reading to determinethe effectiveness of the cleaning solution. If the pH is still >8.0 then the cleaning solution can be re-used (afterfiltering) in cleaning further oak surfaces with the same or similar wine soils until the pH is eventually neutralisedby the acid soils.

Product use for oak barrels without specialised pressure-spray equipmentUse your own (preferred) method, or,Prepare two parallel timber rails and lay the empty soiled barrel on them with the bung-hole facing upward.Introduce an already pre-prepared, clear, mixed, hot aqueous solution of 1-1.5% Oak Restorer HWF into thebarrel so that it completely fills the barrel to the brim. Allow the barrel to soak with the solution for about 4-6hours or overnight. Drain the solution and inspect the barrel.If satisfied, CIP pressure rinse thoroughly with clean UV/sterile water in a single pass so that all material isrinsed away. Allow the barrel to drip-drain for1 hour on the rails.

Repeat the cleaning procedure if some of the wine-soil and colour has not been removed.

CHEMICAL DOSING & MIXING PROCEDURES

Powder into water–Chemical insertion method (Preferred)Fill the supply tank/open top container first with clean hot water.Add the required amount of powder steadily into the water whilst mixing with a perforated handled disc orpaddle. Mix until a consistent solution is obtained.At first, the solution will appear as a ‘milk-like’ colour, but it will soon clarify.Use it when it is clear.If a smaller pail is used, avoid creating a thick slurry of cleaning solution, which may agglomerate whendischarged directly into the water.

Water into powder–Water infusion methodMeasure the powder and place in the supply tank/open top container.Ensuring that the water pressure is not too great, use a hot water-hose with an end, open/close valve so thatit disperses the product upward from the pail bottom and into the hot water.Finish preparing a consistent solution by using a perforated handled disc or paddle for a minute.At first, the solution will appear as a ‘milk-like’ colour, but it will soon clarify.Use it when it is clear.
