funnily enough i have just bottled a Nebbiolo Punch kit. I left the wine for 4 weeks as I am not so naive to believe it would ferment out in 4 days it probably took twice as long but I racked it and left a further 2 weeks plus then fined and left longer than the instructions in total from start to bottle 5 and a half weeks but that was me it could be done in 2 weeks.
It came with 7 litres of grape juice which would have made a 11.5 abv plus wine but added a little sugar to boost the abv. Taste wise it is very good especially as it is still raw and fresh. Would I buy it again yes its taste on this kit is as good as any of the mid range kits CC Beaverdale etc. It can be ready very quick but I think 2 weeks from grape to bottle is about right in my opinion
