16 Reduction Sulfides Causes Juice nitrogen imbalances Fungicide (sulfur) residues Excess sulfate Remedies Prevention! Aeration Copper Sulfate
17 Aeration/Splashing H 2 S + Air Mercaptans + Air = Disulfides = bad idea! Why? In Barrel: Disulfides In Bottle: Disulfides => Mercaptans Sensory Threshold 30 µg/l 1 µg/l
18 H 2 S Prevention Assess juice nitrogen status Add juice nutrients selectively Lower elemental sulfur residues Reduce solids in whites Add SO 2 at crush Inoculate early/reduce inoculum Use low H 2 S-producing yeast strains Lower fermentation temperature Aerate fermenting must
19 H 2 S Prevention After fermentation Rack off lees immediately if smelly Don t aerate wine with mercaptans Test bulk wine for disulfides Removal Add copper sulfate solution (Bench test!)
