Type of wine:
SafŒno™ HD A54 has been created through a Lesaffre R&D yeast hybridization program. This work aimed to overexpress fermentative floral and fruity higher alcohols and their corresponding acetate esters while keeping a clean fermentation profile for light young wines.
Dosage for still white and rosé wines: 20-30 g/hl, straight after settling
Due to its extraordinary high production of isoamyl alcohol / isoamyl acetate and 2-phenylethanol / 2-phenylethyl acetate, SafOEno™ HD A54 is bringing to your wines intense fruitiness towards banana, candy and strawberry notes.
Its capabilities to maintain high total acidity and to bring roundness and sweetness is interesting to keep a very gourmet balance.
The moderate production of ethyl esters by this strain combined with a very high isoamyl acetate production, acting as a flavor enhancer, allows to systematically strengthen the aromatic intensity of the wine, particularly on fermentative notes. It makes this strain a really good tool to value neutral bases or to bring complexity to aromatic bases. This property leads as well to remove green aromas due to early picked grapes for delightful wines.
Considering its low SO2 production, this strain is particularly suitable for low SO2 content wines and favor malolactic fermentations.
SafOEno™ HD A54 will help winemakers adding value to their young and non-varietal wines.
Lesaffre know-how and continuous yeast production process improvement lead to obtain an exceptional quality of dry yeasts able to resist to a very wide range of use, cold or no rehydration included, without affecting their viability, kinetic and/or analytical profile.
Winemakers can choose usage conditions that fit the best their needs, i.e.:
Melon de Bourgogne, Loire valley, 12.2% v/v, Adjustment with DAP from YAN/S = 0.3 to 1 and Adjustment of turbidity (60 NTU) with 30g/hl SpringCell at yeast inoculation, fermentation temperature constant 18°C (64 °F).
12 professional tasters. (* significant at 5%, ** 1%) OAV: Odor Active Value (Concentration/Perception threshold)
Carton of 20 vacuum-packed sachets of 500g each (Full box net weight: 10 kg).
The high rate of dry matter of our yeasts assures an optimum storage in its original packaging at a temperature not higher than 20°C (during 3 years) and 10°C for an extended storage (4 years). Fermentis guarantees the product complies with the International Oenological Codex until its Best Before End Date in the storage conditions mentioned above.
Each Fermentis yeast is developed under a specific production scheme and benefits from the know-how of the Lesaffre group, world leader in yeast manufacturing. This guarantees the highest microbiological purity and maximum fermentation activity.
