Oeno Concept, an Épernay based company, has over 40 years of expertise in automatic riddling and all areas relating to the crafting of champagne. Oeno Concept therefore offers a range of winemaking equipment for Champagne production, including Remulab. This is a robotic system that can improve the bottle riddling process, a crucial stage that influences the final quality of the product.

The riddling process in Champagne

In the méthode champenoise, or traditional method, riddling is carried out after the second fermentation, but before the disgorgement and dosage. Riddling allows the yeast sediment that has formed after the fermentation process to be gradually displaced to the neck of the bottle. The bottle is turned successively to the left and to the right several times a day, while being held at an angle that gradually progresses from a horizontal to a vertical position. Thanks to the riddling, the yeast sediment is moved towards the opening of the bottle, i.e. the neck, and will be removed through the process of disgorgement.

In the past, riddling was carried out by hand. Madame Clicquot invented the riddling rack to make her employees' work easier. Nowadays, with certain exceptions, riddling is automated and is carried out on machines known as "gyropalettes".

Remulab in brief  

Oeno Concept has developed Remulab, an analytical tool that faithfully reproduces the rotation and tilting movements of a riddling machine thanks to an integrated camera that follows the entire riddling process. The camera captures the movement of the sediment frame by frame.

This invention offers time, quality and efficiency benefits. Remulab can be used to create a high-quality riddling programme, saving time by monitoring the movement of the sediment, position after position. It also allows the detection of sediment problems during the riddling by analysing the sediment’s displacement throughout the entire process. Lastly, Remulab can be used to test the effectiveness of additives or any type of winemaking product and to test the behaviour of the sediment in a new bottle shape.
