Used to be the grape of choice for the gentleman who had a vinery.
Where I used to live had one with four Black Hamburg, the roof apex was a good fifteen foot plus, the vines were planted at an angle at the front edge, with a large raised, concrete edged, bed outside for application of dung etc, inside was a duckboard floor on rather compacted soil, while on the back wall was a climbing ophelia, fronted by a five foot deep rainwater tank, then heating pipes below the cast iron grating path. I think there may have been more heating pipes over by the root end. The vines were trained up the four foot front vertical and then up the twenty foot angle to the apex.
Biggest wooden step ladder you have ever seen for pruning and harvesting and general mollycoddling of the fruit, thinning scissors to get that perfect bunch for the master.....
The main stems were over four inches in diameter, this was in the '70s.
Sadly when the place was sold and re-developed the kitchen garden area became a small meadow and a large mews development. That part of the wall still has traces of whitewash and timber fixings.
Bottom line is it is a strong, vigerous and large plant.
