Grappa site (Italian)
- For those interested in grappa there is an Italian home distillation
of grappa site -
I did a computer translation but still had to use context and
guesswork to understand a lot of it.
Under 'The vinaccia' the composition of 10 kg of grapes is given (see
also my msg 4808):
stems 0.3-0.4 kg
skin 0.9-1 kg
seeds 0.3-0.4 kg
flesh 8-8.5 kg
It appears that grape pomace contains about 5% abv or if unfermented
about 10% fermentable sugars.
