Lallemand QA23 White Wine Yeast – 125g

Description

An excellent white wine yeast that will contribute flavour and enhance the bouquets of the grapes during fermentation.

Suggested use circa. 350L

For fresh, fruit-focused whites reliable fermenter rated highly in thiol conversion to bring about enhanced aromatics.

QA23 was selected in Portugal by the University of Tras os Montes e Alto Douro (UTAD) in cooperation with the Viticultural Commission of the Vinhos Verdes region. Suited for production of fresh, fruit-focused, clean white wines, maximises varietal concentration and expression. Particularly for Sauvignon Blanc, Riesling, Chenin Blanc, Chardonnay and Semillon. Produces glucosidase, which allows the release of bound terpenes when present in the must resulting in more fruity varietal aromas. Relative to other yeast strains, QA23 has low nutrient and oxygen requirements, and will ferment juice with low turbidity at low temperatures (10°C) to dryness. QA23 is one of the leading Riesling yeast in Australia, where it produces elegant, well structured varietal rieslings. Australian and New Zealand experience with this yeast has demonstrated that it can ferment down to 10 degrees once the fermentation has started and there are no other limiting conditions.
