LalVigne is an organic yeast derivative product that is applied in the vineyard as foliar spray at veraison. The yeasts used in its production were sourced from the Lallemand wine yeast collection. A single vineyard treatment with a LalVigne spray consists of two applications. The first is done at 5% veraison and the second 10–12 days later.LalVigne is easily suspended in water and applied using a spray rig or hand sprayer. In warmer wine regions ideal conditions for spraying are before the heat of the day. In the cooler regions, a window of 24 hours between rains is needed to get maximum effect. Intermittent rain after this point will not affect the efficacy of the product.
WHY USE IT?All winegrowers face the harvest challenge of achieving phenolic and enological maturity at the same time. Application of LalVigne has been shown to encourage the concentration of aroma precursors in grapes and it can have a noted impact on the timing of the phenolic maturity.
