RIPEN UP!
CONVERTING HERBACEOUS
TO TROPICAL/BLACK FRUIT
It is well known that methoxypyrazines are sources of
herbaceous character in certain varieties, for example
Sauvignon Blanc and Cabernet Sauvignon. In these,
and other varieties, another culprit of greenness, the
‘cut grass’ aroma, are C6-compounds (containing 6
Carbon-atoms). Examples hereof, are alcohols and aldehydes.
The presence of these compounds in grapes
are caused by a lack of ripeness and inadequate antioxidant
protection during the pre-fermentation stage.
Recent studies suggest that during alcoholic fermentation,
C6 compounds (like hexanal) can react with
“sulphur donors” like cysteine or glutathione and form
the precursors of thiols. This precursor can then be
converted into aromatic compounds, like 3-mercaptohexanol
(3-MH) for example, by yeast strains with
ß-lyase activity.
The consequence of this transformation, is the presence
of passion fruit or black currant notes in wine,
instead of green, herbaceous aromas.
RIPEN UP! Enartis suggestions to turn herbaceous
into tropical:
1. During the pre-fermentation operations, limit
the generation of C6 compounds.

the press
• Red grapes: AST in the bin + Enartis Tan Rouge
in the crusher
2. At yeast inoculation, provide “sulphur donors”.

• Red grapes: Incanto N.C. White
3. Ferment with yeast strains with ß-lyase activity
that is able to hydrolyze the thiolic precursors
generated during the fermentation and reveal
the tropical character.
