Reducing ethanol removes one of wine and beer’s natural protective barriers, increasing susceptibility to spoilage bacteria, refermentation and instability.
Key challenges producers face:
• Higher microbial pressure
• Reduced SO₂ tolerance
• Shorter shelf-life expectations
Smart microbial control is essential, combining robust fermentation, bioprotection and precision processing to maintain quality without compromising flavour or clean-label goals.
As low & no-alcohol demand grows, bacterial management becomes a quality differentiator, not just a safeguard.
How are you managing microbial stability in low-alcohol products?

Grenache is a versatile grape, offering juicy red fruit, soft tannins, and a hint of spice. Perfect for bold reds or blends, it delivers wines that are both approachable and layered in character. Many of our Pinnacle Wine Yeast portfolio are perfect for bringing out the best in this grape.

It takes all of a winemaker's experience, skill and passion to craft an outstanding and memorable wine that will delight existing customers and attract new ones. Younger consumers, in particular, are looking for new taste experiences, increasing the demand for wines with bold flavors and aromatic complexity — but without negative characteristics.
Throughout history, winemakers have been aware of reduced acidity and other undesirable changes in their wine after fermentation. However, it was challenging to control these changes because they didn’t fully understand why they occurred. In the early twentieth century, scientists discovered the lactic acid bacteria responsible for this malolactic fermentation (MLF).
AB Biotek continues to pioneer wine yeast product development, drawing on its extensive knowledge of fermentation and production and its mastery of science and technology. The company has now developed an innovative new solution that modifies the malic acid found in grape juice. The resulting product is Pinnacle™ MLF Bacteria, which helps improve and control fermentation and reduce acidity.
Today’s winemakers can now use Pinnacle’s MLF Bacteria to enhance their wines’ flavor profiles and mouthfeel, as well as to ensure greater stability and extended shelf life. Each of the three new products in the portfolio will advance winemaking in different ways.
- Pinnacle™ MLF Extreme excels in low pH and low-temperature conditions, enhancing fruit aromas and complexity.
- Pinnacle™ MLF Robust is ideal for high-alcohol wines, adding red berry notes and spice with soft tannins.
- Pinnacle™ MLF Safe is versatile, reliable and stress-tolerant across a wide range of wine types.
AB Biotek has specifically developed its Pinnacle wine ingredients range to be the winemaker’s choice for complete formulations for premium wines with minimal fuss and ease of use in the winery.
AB Biotek focuses on providing winemakers with products to enable them to consistently create the style and quality of wines their customers enjoy while developing exciting new flavors for the discerning new customers that are crucial to a winery’s success. It supplies some of the world's leading winemakers with a portfolio of oenological technology and a complete range of high-quality solutions.
