From the specification: Passito grapes are dried in fruttai; vendemmia tardiva grapes are late-picked and dried on the vine; no enrichment is allowed for either, and both must age until at least 30 June after the harvest. The passito lines give 'zuccheri residui: 45,00 g/l' without saying minimum or maximum, so not recorded. Spumante Metodo Classico (also Rosé) may name Chardonnay, Pinot bianco, Pignola, Rossola or Nebbiolo and ranges from dosaggio zero to demi-sec. Varietal wines may name any variety suitable for Lombardy, of matching colour, for every type. Natural alcohol may be reduced by 0.5% in poor years.
