Lalvin 71B™ is a high ester producer, which gives the wines a characteristic fruity (fruit salad) aroma. It is known for the production of the ester isoamyl acetate (3-methyl butyl acetate), an ester described as having a banana and pear aroma. Hence it is useful to use in ‘neutral’ grape varieties to increase the expression of fruity characters. The cell walls of Lalvin 71B™ are also highly adsorptive of polyphenolic compounds, thus limiting the tannic structure of red wines.
Lalvin 71B™ also undertakes malo-ethanolic fermentation, a biochemical pathway whereby some malic acid is degraded during alcoholic fermentation. Between 20-40% of malic acid in the juice can be metabolized this way. Due to a low nitrogen demand, low H2S production and low production of SO2, this yeast is ideal to use in preservative-free wines.
