Certification Process

The CVRVV, the certifying entity of the Designation of Origin (DO) Vinho Verde and Geographical Indication (IG) Minho, in accordance with the NP EN ISO/IEC 17065 standard, adopts the following certification scheme: scheme 4 with the exception of point VI (c), defined in the NP EN ISO/IEC 17067.

Bottled product certification process




The quality and genuineness of wine products from the Vinhos Verdes Region are attested to upon the affixation of the CVRVV guarantee seal. The guarantee seal serves as public proof of the DO Vinho Verde or IG Minho authentication. 

Certification is granted providing the following product requirements have been met:
Batch approved analytically (physical-chemical and sensory tests);
Labeling approved, according to the inventory record and the wine product analysis;
A batch id has been listed in the inventory record, with the specifications on the label.

Registration
All natural or legal persons engaged in the production and marketing of wine products with DO Vinho Verde or IG Minho status attributed by the Viticulture Commission of the Vinhos Verdes Region (CVRVV) are subject to registration, excluding the distribution and retail sale of bottled products. Registration must be in line with their prior registration with the Instituto da Vinha e do Vinho as wine sector operators.

To register with the CVRVV, prospective members should complete and submit the form available here, and attach the documents mentioned in chapter I of the Certification manual.

Harvest Yield Declaration for Grapes, Must, and Wine
Before marketing their crop, every year, producers and winemakers must file a Harvest Yield Declaration (DCP) stating the amount of grape, must, and wine produced. 

The Harvest Yield Declaration (DCP) is mandatory for all winegrowers and producers, even if there is no production.


The DCP must be submitted within the legal deadline, between October 1st and November 30th. After that date, the declaration will still be accepted, although failure to comply with the legal deadline constitutes an administrative offense punishable by law.

Producers who do not submit the DCP or submit it after the deadline are subject to:

Prohibition of marketing wine products with DO/IG status;
Full or partial loss of national or EU financial support;
Potential exclusion from group insurance coverage; or
Administrative offence proceedings. 
 
All must or wine declared in the DCP is subject to the payment of a Production Certification Fee, except for table wine.

The maximum yield per hectare of vineyards intended for the production of wines and wine products entitled to DO Vinho Verde is set at 13,500 kg or 15,000 kg for vineyards that meet the productivity and quality requirements set by the CVRVV General Council, with the following exceptions:

- 10,666 kg for vineyards whose last Central Viticultural Register (RCV) update was filed less than 5 years previously;
- 7,500 kg for the remaining vineyards.
The maximum winemaking yield is:
- 75 liters of must for every 100 kg of grapes in the case of both DO Vinho Verde and IG Minho;
- for Alvarinho wine, the maximum is 65 liters of must per 100 kg of grapes.


The maximum yield per hectare of vineyards intended for the production of wines and wine products entitled to IG Minho is set at 20,000 kg, with the exception of the Alvarinho grape variety, which is 10,666 kg.
The maximum winemaking coefficient is 75 liters per 100 kg of grapes.

Wine Spirits (Aguardente) Production Statement

In order to market their production, producers must file an annual Declaration of Wine Spirits Production (DPA).

All wine spirits producers must submit the DPA (Declaration of Wine Spirits Production) by April 30th annually or, alternatively, within a period stipulated by the CVRVV.

The spirits declared in the DPA are subject to the payment of a Production Certification Fee.

Vines / Registration

All winegrowers and producers who wish to take advantage of DO Vinho Verde or IG Minho must register their operational vineyard parcels on the Central Viticultural Register (RCV), the central database for the management of the national wine-growing assets.

They must visit the Regional Directorate of Agriculture and Fisheries of the North (DRAPN) of the area where their vineyards are located to register their vineyard parcels and their legal status. The Vine and Wine Institute (IVV) is responsible for ensuring the conditions for updating the RCV in the Vine and Wine information system.

Based on the daily synchronization of databases, the CVRVV receives information on vineyard registrations digitally from the IVV, and applies it to the recordbooks, namely for the purpose of monitoring the yield per hectare.

Premises
Production, distillation, storage and pre-packaging facilities must be registered with the CVRVV, and comply with both the applicable industrial activity legislation and the rules defined in the Storage and Pre-Packaging Facilities Regulation.

Facilities must be registered at the CVRVV headquarters and accompanied by the requisite documentation (as listed in the certification manual).

In the case of premises used on a non-permanent and definitive basis, the operators in question may provide proof of registration of the warehouses with the IVV.

Physico-Chemical and Sensory Analysis

Physical-chemical and sensory tests are performed at the CVRVV Laboratory, accredited by IPAC, Accreditation Certificate No. L0226.

The economic operator must request analysis by filling in the appropriate field, selecting the product type, respective analytical function and information regarding the batch to be certified (wine cellar(s), number of liters, and current account).

The set of physico-chemical and sensory tests available for each analytical function per product, as well as the respective legally acceptable values, are available for consultation in Products - Compliance rules. The economic operator may request additional tests contained in the Price List - Analytical Protocol.

For each certification request, a duly identified representative sample of the batch to be certified must be delivered to CVRVV in the volumes and packaging set out in the Certification Manual.

The Test Report is issued by the CVRVV Laboratory and posted in the appropriate field. 

The physico-chemical and sensory tests are carried out within a maximum of four working days after receipt of the request. Urgent requests can be made by paying an amount set in the Price List ; urgent analyses are delivered within 48 hours, provided the request for analysis is accepted and the sample delivered by 10 a.m.. Urgent requests received after 10 a.m. will only begin to count time from the following business day.

Labeling

All labeling must be assessed and approved by the CVRVV, and must comply with both the Internal Labeling Regulations and the applicable legislation.

Inventory

Products entitled to DO Vinho Verde and IG Minho must be accounted for in specific, updated records of type of product and quality, known as a wine inventory , which means a record can be kept of all information regarding incoming and outgoing shipments of the product at the premises of the economic operator.

An inventory batch is created when the DCP is submitted, or whenever information regarding specific certification is needed for labeling (e.g. harvest year, subregion, grape, etc.).

Valuation

Certification will be granted if all the requirements defined for the product are met: test report, labeling, and inventory batch.

Revision and Decision

A digital process is used to revise assessments and decide on the certification process. This process verifies compliance with the set of applicable requirements, immediately generating the certification document for the respective batch.

Certification document and guarantee seals
The Certification Document proves the approval or rejection of the DO Vinho Verde or IG Minho certification and provides for the traceability of the certified batch.

The guarantee seals on labels must be produced on CVRVV-authorized printers at the request of the economic operator and in accordance with the rules established for wine products entitled to DO/IG.

Upon delivery of the stamps, CVRVV collects the Marketing Certification Fees (Price List – send to link) and the Promotion, Coordination and Control Fee (responsibility of IVV).

Bulk product certification process


Wines and wine products suitable for DO Vinho Verde may only be sold in bulk to wholesalers registered with the CVRVV.

IG Minho wines can be sold in bulk either to CVRVV wholesalers or to the end consumer.

Wholesale circulation and marketing can only be carried out provided that, upon shipping, the products are accompanied by a previously validated and certified EDA (the export customs declaration) or the DAA from CVRVV.

Only the Minho regional wine can be sold to the end consumer in bulk form.

When the transaction is intended for the endconsumer, CVRVV will charge a Certification Fee according to the price list.
