Quality Improvement in Wine Grapes
Through Agrology Success Stories in Greece and Abroad, it is proven that the superior quality and integrated innovative technologies of Agrology’s Functional Crop Nutrition® products, make a difference in crops from the very first applications!
Our goal is to demonstrate that application programs with Agrology’s Functional Crop Nutrition® products are an obvious investment for producers, as the financial benefits exceed the cost of supplemental applications!
One such Success Story was carried out in wine grapes var. Vidiano (SS 2024_140_GR), in collaboration with the Agricultural Supplies Store and Nutrimaster® “Kontzedakis Georgios, in 2024. Throughout the process, the farmer benefited from the continuous guidance and support offered by Agrology’s Technical Department and the collaborating agricultural store.
The vineyard was divided into two equal plots, one was used as the Control, while Agrology’s Program was applied to the other plot. In both plots, the farmer used the same plant protection and plant nutrition-fertilization program, apart from the additional applications with Agrology’s products.

- Improvement of Wine Quality Characteristics
Agrology Crop Nutrition Program
Gravital® Energy
A Silicium (Si) Biostimulant, with high availability of Orthosilicic acid, the only assimilable form of Silicium by plants.
- Enhances production and improves its quality.
- Increase in resistance to both abiotic and biotic stress factors, including thermal stress, water stress, salinity, and toxicity of elements.
- It promotes photosynthesis and enhances Water and Nutrient Use Efficiency.
- Facilitates the absorption of macronutrients such as Nitrogen, Phosphorus, and Potassium
Application timing:
- Grape Increase
- 30 days before Harvest
Recommended Dosage
Foliar application – 1,8 Kg/100lt
Success Story Results
During the field trials, sampling was conducted for both treatments: the Control and the Agrology Program. Specifically, grape samples from both treatments were sent to the “CHIMIKOTECHNIKI” laboratory in Rethymno, Crete, for the determination of wine quality characteristics. As a result, the Agrology Program demonstrated impressive improvements in the qualitative characteristics of vineyard cultivation, benefiting the producer.
Specifically, the following were achieved:
1. Improvement of Wine Quality Characteristics
- Decreased pH: Increased acidity, which is critical for flavor profile, microbial stability, and the long-term aging potential of wine.
- Elevated Potassium Levels: Modulates wine acidity and plays a key role in buffering pH fluctuations.
- Enhanced Ammonia Concentration: Serves as a nitrogen source for yeast metabolism, promoting robust fermentation kinetics.
- Increased Total Acidity: Fundamental for preserving the sensory balance and overall organoleptic properties of wine.
- Elevated Ethanol Content: Contributes to mouthfeel, viscosity, and the perception of warmth, enhancing wine body and complexity.
- Higher Tartaric Acid Concentration: A principal organic acid in wine, essential for taste profile, aging capacity, and structural stability.
- Increased Malic Acid Content: Imparts tartness, particularly in young wines, enhancing flavor intensity and freshness.
- Elevated Total Sugar Concentration: Influences perceived sweetness; moderate increases can enhance balance, particularly in high-acid wines.
