How to enhance length and freshness in white and rosé wines with CAUDALYS™ 

Introduction 

Producing mineral, fresh and crispy white and rosé wines, that are long on the palate requires precision and know-how. 

Warm vintages and lower acidity often lead to wines lacking tension, structure and length. For winemakers, the challenge is clear: how to restore balance while preserving elegance and wine sensory quality. 

Within this framework, specific yeast derivatives such as CAUDALYS™, the first ever wine yeast derivative produced from Torulaspora delbrueckii for winemaking applications, offer a new approach to fine-tuning sensory profiles. 

A targeted approach: why CAUDALYS™ is different 

One key element highlighted in the data is that not all yeast derivatives behave the same way. 

CAUDALYS™ is produced from a specific strain of T. delbrueckii, selected for its unique composition. As shown in research, yeast composition varies significantly depending on the strain, directly influencing its functionality in wine.  

In addition, its production relies on a dedicated process (the Specific Design Culture Process, SDC™) designed to preserve active compounds linked to sensory impact, ensuring consistent performance in winery conditions. 

Enhancing freshness, minerality and length in whites and rosés 

One of the most consistent challenges in white and rosé winemaking is achieving freshness and palate persistence, especially in softer or riper profiles. 

Trials in Chardonnay show that the addition of CAUDALYS™ significantly enhances: 

In rosé wines, similar improvements are observed, with a notable increase in: 

These results illustrate how CAUDALYS™ can be used to reinforce precision and tension in finished wines. 

Flexible use at different stages of winemaking 

Beyond performance, one of the strengths of CAUDALYS™ is its versatility in application. 

Trials confirm that it can be used: 

When added to finished Chardonnay wines, improvements in aromatic intensity, minerality and length are also observed.  

This flexibility allows winemakers to use CAUDALYS™ both proactively and as a fine-tuning tool. 

A valuable tool for No Low and sparkling wines 

No Low alcohol wines often struggle with lack of structure and persistence. Initial trials show that CAUDALYS™ can restore when added to wines after dealcoholisation.  

Similarly, in sparkling base wines, its addition in enhances: 

This makes CAUDALYS™ a relevant option across still, sparkling and low alcohol wines. 

Practical takeaway for winemakers 

CAUDALYS™ provides a practical solution to one of today’s key issues: how to improve wine structure without heaviness. 

It is particularly relevant when: 

Its flexible use allows winemakers to adapt timing and dosage depending on the objective, from fermentation management to final blending adjustments.
