GNS wine, port and spirits services into London
I can only add that GNS' Drake (delivered1938) and Auk (delivered 1947) were regular runners from SW France and Portugal into London, as my father was mate on these during 1954-1959, including summer rush spells on their pleasure steamers such as Royal Sovereign. We used to go onboard Auk and/or Drake to meet him, not far from Tower Bridge. GSN had a bunch of wharfs since before WWI, ging from Deptford to London Bridge, including wharfs near Tower Bridge beside or on the previous Brewers, Chesters and Galley Quays (1910-1940?). Loading in Portugal in the 1950's was interesting - Oporto had a small upriver wharf. They had to go upstream of this wharf with the flood tide, and turn around in the narrow river by running the bow into the bank and letting the tide push the stern upriver as they floated off, and then they headed back downstream to tie up at the wharf to load the barrels and pallets of port and other booze. At low tide they sat on the mud. My mother was happy in this period, she was never short of booze, but preferred gin to port lol.
