SafŒno™ HD S135

Available in 500g and 10kg packaging.


This product is E2U™

What does this mean?


SafŒno™ HD S135 is coming from the hybridization of two Lesaffre strains with the aim to combine their best characteristics towards polyphenols coating and resistance to difficult fermentation conditions for fruit driven middle ageing reds.

For still White & Red wines. Dosage:20 g/hl
Ingredients: yeast (Saccharomyces cerevisiae x Saccharomyces bayanus), emulsifier: E491 (sorbitan monostearate)

SafŒno™ HD S135 sensory features

Round premium reds

SafŒno™ HD S135 is recommended for red wines whose power is associated with a smooth profile. This strain extracts indeed very well wine polyphenols but has the ability to deliver a round and well balanced structure. This feature can also be enhanced due to its low malic acid consumption. This favors wine processing between alcoholic and malolactic fermentation like micro-oxygenation.

Aroma enhancer

SafŒno™ HD S135 promotes the production of fruit driven reds, rather oriented on ripe red/black fruits. It is particularly adapted to varieties such as Merlot, Syrah, Tempranillo, Sangiovese and Grenache

Rhône valley – Syrah, 14.2% v / v, traditional vinification

SafŒno™ HD S135 amplifies sensorial characteristics giving highly colored and smooth final wine with intense fruity notes.

  • 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.:
    • Direct inoculation: Pour the yeast on the surface of at least 10 times their weight of must (possibly directly on the top of the tank or during tank filling after settling for whites and rosés). Gently stir to avoid or break clumps. Immediately transfer into the tank via a pumping over with aeration (or homogenize tank volume).
    • With prior rehydration: Pour the yeast on the surface of 10 times their weight of tap water at room temperature. Gently stir to avoid or break clumps. Wait for 20 minutes and transfer into the tank via a pumping over with aeration.
