identified to facilitate its traceability, throughrelevant documentation or information inaccordance with the relevant requirements ofmore specific provisions.MATERIALS AND METHODSImplementation of traceability in wine industryimplies the existence of correlated registrationdocuments for each stage of production anddistribution. For this reason all processes andtechnological operations must be recorded inspecified documents, corresponding to eachproduct stage.Based on the specific technology of grapeproduction to distribution it was considerednecessary to create specific documents toachieve total traceability.This tracking system was developed for awinery located in southern Romania, in thewine region 'Terasele Dunarii' where 500tonnes of grapes of various varieties areprocessed yearly.In order to implement a traceability system, thefirst issue to be resolved concerns the divisionof the entire surface in farms, physical blocksand parcels. It is also necessary that thedivision of the total area takes into account thegrape varieties grown and specific climatic andedaphic conditions because the grapes areharvested and wine batches are formed basedon the grape quality and characteristics. If thesurfaces are not divided properly, the quality ofthe final products may be affected.The specific documents deemed necessary tomaintain a robust traceability system arehereafter presented.Vineyard Record Keeping File. Necessary torecord data from vineyard parcels, thisdocument is a table that contains the followingcolumns:- Date;- Farm / Physical Block / Parcel (F/PB/P) ,same with batch of grapes and containingthe number of a parcel from specifiedphysical block and farm (eg. 1/221/4, whichmeans F/PB/P); this is the most importantkey link for history retrieval;- Area (ha) , referring to parcel;- Preformed works, a column where specificoperations performed in the vineyard aredescribed;410- Auxiliary materials used, referring tofertilizers, pesticides and herbicides;- Dose, referring to dose of the treatmentmaterial used;- Responsible, who is the person whoperformed the work;- Observations, another notes.Grape Maturation Report. Necessary torecord grape maturation evolution data fromvineyard parcels, this document is helping todetermine the optimal time to harvest; is themost critical decision of the grower andwinemaker. Good quality of the grapes atharvest allows for a maximum potential in winequality. Incomplete ripen grapes contain lesssugar, very high acidity, harsh tannins and'green' aromas. Overripen grapes may also leadto uncharacteristic flavor and low acidity. If theassessment is not done properly and harvestdecision is not appropriate, wine quality maybe affected (Zoecklein B.W., 2001).Unfortunately, grape maturity assessment isdifficult to perform, due to the involvement ofseveral factors and the necessity to measureseveral physico-chemical parameters, that arenot always directly correlated (Coombe B.G.,1992; Robinson S.P. and Davies C., 2000).This document is kept for each parcel andcontains the following identification elements:- Variety;- Vintage;- Farm / Physical Block / Parcel, a codewhich is linked with Vineyard RecordKeeping and Harvest Delivery records.In addition to the identification elements, thisdocument contains sets of analyzes of grapesfrom that parcel (Date; Sugars, in g/l; TotalAcidity, in g/100 ml tartaric acid, pH, Brix,Brix*pH² index, Brix/TA index and% v/vestimated alcohol).Harvest Delivery Note. It is a document thatmust contain the following identificationelements: Document number; Variety; Farm/ Physical Block / Parcel; Estimated quantity(kg) ; Real quantity (kg) . This documentaccompanies the grapes to the wine cellar andused for tracking and accounting records. Theestimated quantity is evaluated at the floweringstage and is used for planning in the cellarahead of harvest.Quantitative Grape Receiving Report. It is atracking document used to link the small grape
