How to manage ZOI wine certification in Croatia

Step-by-step guide to tracking Protected Designation of Origin (ZOI) certification for Croatian wines using Cepaos.

2 min lectura

What is ZOI

Zasticena oznaka izvornosti (ZOI) is Croatia's equivalent of the EU Protected Designation of Origin (PDO). ZOI wines must originate entirely from a defined geographic area, use approved grape varieties, and meet strict quality standards. Croatia also has Zasticena oznaka zemljopisnog podrijetla (ZOZP), equivalent to PGI. Cepaos tracks grape origin and variety to verify ZOI/ZOZP eligibility.

Prerequisites

  1. Vineyard blocks with ZOI/ZOZP zone assigned in Vineyard > Blocks.
  2. Harvest records linked to blocks with weights.
  3. Lab results in the Lab module.
  4. Cellar book with complete records.

Step by step

1. Access ZOI compliance

In the sidebar, under Compliance, click ZOI Certification. Your current-vintage wines are listed with their origin breakdown.

2. Review origin percentages

For ZOI wines, 100% of grapes must come from the defined area. For ZOZP, at least 85%.

WineIstria (ZOI)Croatian Coast (ZOZP)Other
Malvazija Istarska 2026100%0%
Red Blend 202670%92%8%

The Malvazija qualifies for Istria ZOI. The Red Blend qualifies for Croatian Coast ZOZP but not Istria ZOI.

3. Check variety rules

Each ZOI zone specifies permitted varieties:

  • Istria: Malvazija Istarska, Teran, Muskat.
  • Kutjevo: Grasevina, Pinot Noir, Chardonnay.
  • Dingac: Plavac Mali only.

Cepaos flags non-compliant varieties.

4. Verify analytical requirements

ZOI wines must meet minimum alcohol, maximum yield, and sensory quality standards. Cepaos checks your lab data against these thresholds.

5. Generate certification documents

Click Generate ZOI Certificate. Cepaos produces a document with origin proof, variety breakdown, and analytical results.

6. Submit for official certification

Download the document and submit it to HAPIH for quality evaluation and ZOI certification. After approval, enter the certification number in Cepaos.
