CONCENTRATED AND PURIFIED ENZYME PREPARATION WITH PECTOLYTIC ACTIVITIES. IN ACCORDANCE WITH THE INTERNATIONAL OENOLOGICAL CODEX.
Specific enzymes to ameliorate and rationalize the release
of white and rosé juice during the pressing.
Preparation developed by LAFFORT OENOLOGIE.
- Pectinase Activity > 5000 FDU 20 °C/g
cinnamyl-esterase activity < 0,35 CE/FDU 20 °C.
- Specific enzyme for the direct pressing of white and red grapes.
-Purified of cinnamyl-esterase in order to reduce the later production of vinyl-phenols during the fermentation.
-Increase the free run juice rates.
-Increase the total yield of quality juice.
-decrease the volume of gross lees.
-Favour the selective extraction of premium components during the pre-fermentation phases. Particularly if skin contact is desired.
-Ameliorate the aroma potential.

LAFAZYM PRESS is a preparation of enzymes made to facilitate the juice liberation during pressing, but also to ameliorate the intrinsic quality of must. Recent studies have indicated the importance of monitoring the pre-fermentation processes, particularly at the press stage, before the beginning of the fermentation. LAFAZYM PRESS facilitates an optimisation at this critical stage.
During the use of LAFAZYM PRESS, it is not necessary to add pectolytic enzymes for settling, except in some particular cases, at low dosage (LAFAZYM CL at ± 5 ppm), in the last pressings.
2 to 5 g/100 kg of grapes according to the varietal, the ripeness and the quality of the grapes .
Dissolve in 10 times its weight in water and use within few hours.
Remark: do not add bentonite during the treatment with enzymes.
Tin of 100 g – box of 10 X 100 g.
Carton of 10 kg (100 X 100 g).
