Lalvin QA23 Wine Yeast 125g

$26.50 incl. GST

Suited for production of fresh, fruit-focussed, clean white wines, Lalvin QA23 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.
