Fermentation is the cornerstone of winemaking, directly influencing flavour, aroma, and stability. Selecting the right yeast strains and fermentation aids is crucial to achieving consistency and excellence. By integrating high-performance products like Lalvin DV10, Lalvin QA23, and Rectified Concentrated Grape Must (RCGM), winemakers can optimise fermentation, improve wine stability, and elevate sensory attributes.

Lalvin DV10: The Workhorse for Robust Fermentations

When consistency and reliability are required, Lalvin DV10 is the preferred yeast strain. This Saccharomyces cerevisiae strain is known for:

  • Strong fermentation performance, even under challenging conditions.
  • High alcohol tolerance, ideal for sparkling and high-alcohol wines.
  • Preserving fresh aromas and acidity, ensuring a balanced final product.

DV10 is widely used in traditional method sparkling wines due to its ability to ferment cleanly and resist stress factors like low pH and high pressure.

Lalvin QA23: Unlocking Aromatic Complexity

For winemakers aiming to enhance aromatic profiles, Lalvin QA23 offers exceptional benefits. Selected for its ability to bring out fruity and floral notes, QA23 is ideal for:

  • Low-foaming fermentations, ensuring easy handling.
  • Producing crisp, aromatic whites, including Sauvignon Blanc and Chardonnay.
  • Reducing hydrogen sulphide production, minimising off-flavours.

QA23 promotes a clean, fresh expression of varietal character, making it an excellent choice for white and sparkling wine production.

RCGM: Precision in Fermentation Control

Rectified Concentrated Grape Must (RCGM) is a purified grape-derived sugar source that offers winemakers greater control over fermentation kinetics. Key advantages include:

  • Providing a clean sugar source for secondary fermentation in sparkling wines.
  • Ensuring consistent yeast nutrition, reducing the risk of sluggish fermentation.
  • Maintaining neutral flavour impact, preserving the integrity of the wine’s profile.

By incorporating RCGM, you can achieve a precise, controlled fermentation process, particularly in secondary fermentations and dosage adjustments.

Achieving Fermentation Excellence

The combination of Lalvin DV10, Lalvin QA23, and RCGM provides winemakers with a complete toolkit to ensure fermentation success. Whether enhancing stability, optimising yeast performance, or controlling sugar content, these solutions contribute to higher-quality, more expressive wines.

By leveraging these fermentation aids, winemakers can confidently produce wines that are not only balanced and vibrant but also consistent and shelf-stable. Investing in the right fermentation strategy is the key to crafting wines that stand out in today’s competitive market.
