Your Path to Better Quality!

Wine Grapes

Acadian® is a unique technology containing a complex mix of synergistic bioactive compounds that allows crops to reach their full yield potential. Acadian enhances crop quality and productivity by enhancing root growth, improving nutritional health and bolstering tolerance to challenging growing conditions.

Benefits to Grapes

  • Increases nutritional uptake
  • Creates looser bunches
  • Mitigates environmental stresses
  • Improves wine quality

Acadian Improves Yield and Quality

Acadian works at a cellular level by improving the nutritional status of your crop. This, combined with the unique stress compound production it elicits, results in great juice quality and beautiful wines.


Yield was increased 5%. Prices for Cabernet from Mendocino County are approximately $1,589.28/ton. Returns were increased in the Acadian treatment by $552/acre.

Wine Quality

The wine made from Acadian-treated grapes had higher levels of key quality components such as anthocyanins, tannins and phenolics.

How Does Acadian Benefit Grapes?

Improves Nutritional Uptake:

Acadian improves crops’ nutrient uptake and drives rachis growth (stretch) for looser clusters and better airflow around the fruit. Acadian contains natural complexing sugars that bind to micronutrients, thereby improving their translocation and bioavailability within the plant. When you apply Acadian as part of your regular nutrition program, you’re putting nutrients on the fast track and ensuring your plants get the most out of every ounce of fertilizer.

Rachis Length

Mitigates Environmental Stresses:

Don’t let stress ruin your crop! Acadian helps your crop better resist tough growing conditions by increasing photosynthesis, resulting in improved growth. This improved growth is apparent from grapes treated with Acadian, as they have increased rachis length, allowing for improved airflow and spray penetration into the cluster. With its numerous bioactive compounds such as mannitol, unique polysaccharides and betaines, Acadian improves a plant’s tolerance to a variety of stressful growing conditions including drought, heat, chill and salinity stress.

Brix Distribution

Distribution of Brix Readings from each berry in a cluster.
Acadian®-treated grapes had more consistent brix readings in each berry in a great range between 22 and 26. The Control had many berries with brix measurements that were less than 22.

Improves Wine Quality:

Acadian can be applied to increase yield, while maintaining or increasing wine quality. It increases berry set and reduces crop loss due to stress. In addition, Acadian elicits the production of naturally occurring stress compounds, such as anthocyanins, which contribute to quality of the juice for high-quality wine.

Pinot Noir Yield

Full-season applications of Acadian improved yield production by 5.4%. This equated to almost an additional half ton per acre over the grower’s standard.
