Pure-Lees Longevity™ from Lallemand

Pure Lees Longevity™ – Inactive Yeast for Maximum Freshness and Extended Shelf Life

Protect your wine against oxidation – and enhance mouthfeel, aroma and quality

Pure Lees Longevity™ is a premium inactive yeast from Lallemand, developed for winemakers who want to ensure freshness, aroma intensity and consistent quality all the way from tank to bottle. The product provides effective protection against oxidation during ageing and bottling while also contributing to a rounder, softer and more harmonious wine.

Why cider makers and winemakers choose Pure Lees Longevity™

• Effective protection against oxidation – extends the wine's shelf life

• Preserves fruit, freshness and aroma by actively reducing dissolved oxygen

• Improves mouthfeel and structure for a more elegant and rounded taste

• Provides the benefits of lees ageing – without the risk of reductive faults or unwanted aromas

• Advanced HPH™ technology ensures higher antioxidant activity than traditional inactive yeast

Higher Quality – Less Risk

Pure Lees Longevity™ is produced using Lallemand's patented High Pressure Homogenization (HPH™), which maximises the oxygen-binding capacity of the inactive yeast. The result is a targeted and reliable solution that:

• Inhibits oxidative ageing

• Preserves the grape's natural character

• Improves the wine's balance and mouthfeel

Compared with traditional lees ageing or standard inactive yeast, you achieve the same sensory benefits – but with full control and without the risk of faults. Ideal for wines intended for longer ageing or optimal bottle performance.
