AEB GUIDES YOU THROUGH THE WORLD OF SPARKLING WINES

Due to the know-how and experience gained in the spumante sector, we are able to offer a comprehensive range dedicated to spumante making, both for the classic and Charmat methods, that includes biotechnologies, process aids and equipment.

We are well aware of the commitment and dedication that it takes to harvest the grapes under the best possible conditions. That's why we are committed to providing specialised support alongside a range of products that make the most of all the winemakers' efforts, with the aim of producing high quality spumantes.

SPUMANTE VINIFICATION

Knowing the precise moment to pick is one of the most important decisions, as this choice will be responsible for the perception of the acid/sugar balance and phenolic and aromatic maturity. On the other hand, the harvesting method directly influences the mashing; in this respect, picking by hand remains the ideal choice for producing high quality Spumantes. Therefore, the design of a Spumante must take into account, the final objective to be achieved, right from the harvest.

Our complete range, which includes biotechnology and equipment, guides the winemaker through all stages of the process. To support the production of the base wine (or vin clair), we provide process technologies to manage the pressing and clarification of the must and wine. In order to achieve these objectives, we propose enzymatic preparations, clarifiers, adjuvants, tannins and antioxidants capable of preserving the most important fractions of must and improving its qualitative parameters.

OUTSTANDING CLARIFICATION VERY QUICKLY

During the clarification phase, E-Flot, flotation equipment for must clarification, that allows the use of oenological products to be limited and the need for optimal clarification to be met in a short time. Our RANGE includes specific biotechnologies and adjuvants to tackle problems of all types, from oxidation to spontaneous fermentation, and to obtain perfectly clear musts.

ALCOHOLIC FERMENTATION WITH SELECTED YEASTS

For primary fermentation, the Fermol line provides the winemaker with an enormous number of selected yeasts for the production of base wines with an extremely clean and defined profile, with a more neutral or more intense bouquet depending on the strain chosen. Furthermore, we combine the yeast offer with Fermoplus organic and complex nutrients, designed to promote yeast rehydration, a correct fermentation process and enhance the wine's aromatic profile.

MANAGING ACIDITY, PH AND MALOLACTIC FERMENTATION

The acidity of a Spumante is defined by the organic acids present in the wine: tartaric, citric, malic, lactic and carbonic acids. It can be managed with products to replenish the lack of acid framework or for deacidification. In addition to a full range of lactic bacteria, we have specific yeasts that can decrease malic acid without producing lactic acid.

In the production of spumantes, pH is a key factor as it influences important quality parameters such as microbiological stability, tannin/protein reactivity, colour stability, oxidability and the balance between free and molecular SO₂. To manage this important parameter, we offer the Stabymatic range, automatic cation exchange plants for pH lowering and tartaric stability.

PREPARING THE WINE FOR FROTHING

Generally speaking, the chemical composition of the base wine before frothing, the decisive phase for the final quality, can present factors that do not bode well for refermentation, such as high acidity, low pH and moderate alcohol content. In order to achieve a successful second fermentation, we offer a complete range of ellagic and proanthocyanidin tannins, yeast derivatives and nutrients to improve the oxidation-reduction balance, enhance the aromatic profile and ensure the correct and linear course of fermentation. We also have a dosing unit for autoclaves for spumante making using the charmat method, which allows the addition of pre-dissolved liquid or powdered products directly into the autoclave during the entire fermentation process.

SPECIFIC YEASTS AND EQUIPMENT FOR SECOND FERMENTATION

We also have a complete range of yeasts for refermentation: in addition to traditional yeasts, we have developed agglomerating and encapsulated yeasts. The inoculation of our selected yeasts for secondary fermentation is a fundamental process to ensure the production of fine and elegant Spumantes, and to allow the winemaker to achieve the desired result. In order to optimise the fermentation process for both base wine and refermentation, we have developed the Reactivateur 60 and Reactivateur 60 RIF range of models, which eliminate the need for a pied de cuve and allow the prevalence of yeasts in the fermentation right from the start.

Each spumante is the result of a well-defined project of which the fermentation technology is an integral part. After the second fermentation, depending on the pre-established technological objective, the wine may spend a period of maturation on the yeast lees, gaining greater complexity and specific aromatic notes. After refermentation, the dégorgement (disgorgement) operation follows, and in order to facilitate the removal of sediment and the clarification of the wine, we provide remuage aids in the range to optimise this stage of the process.

DEGORGEMENT AND PREPARATION OF THE LIQUEUR D'EXPEDITION

After disgorging (or degorgement), the liqueur d'expedition is prepared, an oenological practice designed to correct any imbalances and to further enhance the organoleptic profile of the wine before bottling. To this end, the offer includes additives and stabilising preparations, capable of reducing the perception of bitterness and giving roundness to the wine. The offer is completed with OAKIA, a selection of tannins able to improve the redox capacity, stabilise the colour and enrich the polyphenolic structure of the wine.
