SafŒno™ STG S101 was selected in the Beaujolais region for its high ester production at low temperature.

Still wines. Dosage: 20 g/hl
Fermentation restart. Dosage: 30 to 40 g/hl

For young red & rosés wines

Given its cryophilic characteristic, SafŒno™ STG S101 is an ideal strain for red, white or rosé winemaking wines between 8-10°C. It is also recommended for musts on which a cold pre-fermentation maceration has been made.
SafŒno™ STG S101 develops fruit (especially fermentative esters) & flower aromas making it a strain of choice for primeurs processed from carbonic maceration or thermovinification, as well as rosés. Wines have a fresh and light finish. Thanks to its origin SafŒno™ STG S101 is particularly convenient for Pinot Noir & Gamay as well as all other light red varieties intended to produce wines with a rapid turnover (Young Tempranillo, Sangiovese, Cinsault, Pinotage, Grenache).

Usage

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.:

 

① Direct inoculation:
Pour the yeast on the surface oeasy to usef 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).

 

② 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.

Packaging
