About us

Cromoenos™ is a registered trademark of the company, BIOENOS, S.L., which gives its name to the BIOENOS Business Unit dedicated to selling a range of products and tests for oenological laboratories, following R&D carried out for BIOENOS consulting.

The first marketable product under the Cromoenos™ brand was the Cromoenos Technology Platform presented on this website. Development of other products and solutions is ongoing; such as the Probable Health Kit to apply from veraison.

Cromoenos™ currently gives its name to this website, the Cromoenos method kits, and equipment, such as the X-tractor and GranoX-Tractor.

History

The company BIOENOS, S.L. started its R&D project in 1998 and has been under continuous renewal and improvement ever since. Although it was founded to investigate a grape payment system that indirectly determined excess production, the research was oriented towards a deeper understanding of plant physiology, in this case of the vine. As a result, the Phenolic Maturity Index emerged, which is closely related to the degree of maturity of the grape and is also a marker of its stress state.

The Phenolic Maturity Index takes a numerical value proportional to grape ripeness so a field technician has a guide to follow. In other words, we are in the border area between the study of wine, which is where we came from, and grape cultivation, which is where we are headed, to establish a language with its codes to find out how to ripen grapes well in this era of sudden climate change.

We believe in wine as a work of art that generates emotions of excitement and surprise

Mission and vision

José Pascual Gracia Romeo, a Doctor in Chemical Sciences and oenologist, found that by applying the new knowledge of the oenotechnology and biochemistry of musts, he re-discovered varieties which had fallen into disuse: some about to disappear and others discontinued. By activating the enzymatic potential of the musts and yeasts, he was able to reveal the differentiating aromas of these grape varieties.

Other grape varieties can also benefit from the knowledge provided by monitoring the Phenolic Maturity Index, which allow the vineyard to be directed so that the strain synthesises the aromatic precursors which only it knows how to produce, with a surprising odorific power that the winemaker can develop under fermentation. Thus, there may be many more grape varieties that are authentic oenological jewels, waiting to be rescued from anonymity with the help of science, technical expertise and enthusiasm.

Cromoenos wants to put simple laboratory tools – for evaluating unique, local grape varieties – into the hands of a new generation of young winemakers and vineyards with personality, to obtain the best of the plant and agronomic heritage they have in their hands, with the application of scientific knowledge and creative intuition.

We have shared our experience with Agronomists and Plant Physiologists in Precision Viticulture projects to try to apply this same philosophy to other fruits rich in anthocyanins, such as strawberries, raspberries, blueberries and even red apples.

In 2016, he received the Oenology Research Merit Award from the Spanish Federation of Winemaker Associations.

He was a contributor to the book “The wine sector facing the challenge of climate change: public and private mitigation and adaptation strategies in the Mediterranean”, by writing Chapter 12 “Climate change and grape ripening: Prevention of blocking and precision winemaking”. This publication was deserving of the award given by the International Organisation of Vine and Wine (OIV) in 2019, in the category of Sustainable Viticulture.
