Level2™ Solutions: non-traditional yeast for use in sequential inoculation Flavia™
Metschnikowia pulcherrima yeast selected by the Universidad de Santiago de Chile for its specific capacity to release arabinofuranosidase activity. When used in sequential inoculation with a compatible selected Saccharomyces cerevisiae yeast strain, FLAVIA™ will impact the production of such varietal aromas as terpenes and volatile thiols in Riesling and Sauvignon blanc.
Torulaspora delbrueckii yeast offered individually. Now winemakers can pair it with the appropriate Saccharomyces strain for both red and white wines such as Chardonnay, Syrah & Pinot noir to promote complexity and mouthfeel.
LALVIN RBS 133™
LALVIN RBS 133™ is the result of the collaborative yeast selection program among more than 130 yeast isolated from grape bunches by UNIVERSITÀ DEGLI STUDI DI PADOVA, Lallemand and CONSORZIO TUTELA VINI DEL PIAVE D.O.C. RBS 133™ has the ability to complement the fruity characters of grape varieties such as Sangiovese, Montepulciano, Barbera, Raboso and Tanat, even in difficult conditions of low temperature, low nutrient content, high acidity and high alcohol level. In North America, RBS 133 is also excellent for fermenting hybrid reds!
O-MEGA™: much more than a New Wine Bacteria, a strong ally for malolactic fermentation
The Institut Français de la Vigne et du Vin (IFV), in partnership with Lallemand Oenology, has selected, over a four-year period, a new wine bacteria – O-MEGA™ – that is both vigorous and versatile and brings fruity freshness to white, rosé and red wines.
The O-MEGA™ wine bacteria can be inoculated into wine without rehydration, and is very easily implanted no matter when it is added (in co-inoculation, early inoculation or sequential inoculation), to conduct malolactic fermentation (MLF) in a short time – even in difficult conditions. Inoculation with O-MEGA™ is very simple, as confirmed by numerous winery trials that show its remarkable resistance in a wide range of uses, with white, rosé and red wines:
– pH ≥3.1
– Degree of alcohol <16%/vol, even 17%/vol if the other factors are not limiting
– Total SO2 <60 mg/L, free SO2 10 mg/L
– Temperature >15°C
When O-MEGA™ was characterized in greater detail, it revealed properties that go well beyond deacidification:
– Good resistance to polyphenols, which lets O-MEGA™ be effective in varietals where MLF can be difficult, like Merlot and Tannat
– Weak degradation of acetaldehyde during and after MLF, which permits better colour stabilization in red and rosé wines
– An ability to degrade both high levels of malic acid (6 g/L) and lower levels (1 g/L)
– Does not metabolize the precursors to hydroxycinnamic acid in grapes, which are the precursors to Brettanomyces for producing the ethyl and vinyl phenols responsible, for undesirable tastes in the wines
– Low production of volatile acidity
– This new wine bacteria selection also offers major sensory advantages, such as very low diacetyl production (milky and buttery notes), and helps develop wines with freshness and aroma complexity, while reinforcing their fruity character
