Very interesting stuff inthere.
The funny thing is, a few years back i got this grape vine from my brother and this year was the first year it actually had grapes. Since then the idea of making my own port/wine keeps haunting me.
The grapes tasted really really good, even better then the ones you buy in a store. Sweet, crispy and well-balanced.
From this 1 vine i harvested about 5-6 kilo's of fresh, pestilence free grapes.

The vine itself is completely surrounded by walls and in summertime it gets sun from 10 AM till 7 PM. Twice a year it gets extra nutritions and during long periods of drought it gets water every week.
The result is very promising so i will get another vine to plant and hopefully that will get me a total of 10 kilo's of fine grapes in 3 years. Maybe enough for 3 bottles of port or wine.
I will keep you informed over time.
Is there anyone else with their own vines or vine-yard ?
