Sure is a natural replacement for sulphites in wine and food products based on a Melissa Officinalis extract. The fluid extract has antioxidant and antibacterial properties, as well as colour preservation capability, without altering organoleptic properties, thus mimicking sulphites function in wine and food. The product is patented. The base plant is harvested in the Netherlands.


We have been working for more than 5 years in the development of Sure. Our product has already been validated through multiple tests on white wine with relevant wineries in France and Germany, demonstrating similar antioxidant (FRAP value) and antibacterial activities as well as colour preservation properties. Sensory tests confirmed that organoleptic properties were maintained. Scientific tests have been carried out in:

Germany: Dienstleistungszentrum Rheinhessen (2014)

France: Chateau Moulin de Lene (2016)

Netherlands: St. Martinus Vijlen, oenoloog S. Beurskens (2016/2017)

Involved institutions: Universities of Gent and Antwerpen, Eco Treasures, Lokeren

Value proposition

With Sure, wine producers will be able to satisfy consumers demand for clean label products, avoiding the use of synthetic additives, while ensuring their wines’ long shelf-life for a viable commercialization. Testing in different countries with different grapes has shown that the samples can be kept at least for 2 years. Its food preservation capacity has already been proven with potatoes.
