Beskrivelse
Lalvin QA23® has a very high β-glucosidase activity, enzymes which help cleave non-volatile aromatic compounds into their volatile state. Hence this yeast contributes to varietal / terroir fruit expression.
It is known to enhance citrus fruit type aromas including lime and grapefruit. Given many terpenes are bound to glucosides, the use of Lalvin QA23® in varieties high in terpenes such as Riesling is highly recommended.
This yeast is also a proven thiol converter, hence excellent thiol expression is achieved. Its use for Sauvignon Blanc is therefore highly recommended.
A very reliable, clean fermenter, Lalvin QA23® respects varietal fruit character, with minimal yeast flavour contribution. Depending on the terrior, some ester production has been reported.
Known for its Reliability and Robustness, Lalvin QA23® tends to ferment well in clarified juice, low in nutrients. In addition. its ability to ferment at relatively low temperatures makes it an ideal choice for the making of many white wines. The fructophilic yeast, hence tends to ferment well at the end of fermentation.
The Lalvin QA23® is one of the leading Riesling yeast in Australia, where it produces elegant, well structured, cool climate Rieslings.
The Lalvin QA23® yeast, was selected from nature, and has since been improved using the Lallemand proprietary process called YSEO®.
