Hi Alf and Astonian,
I have indeed looked at that thread, and some time ago left a bit of info on there regarding the set up when I was there in the 60's and 70's.
I think if Mr Jennings passed on his recipe to anyone, it would have
probably been a local company rather than R Whites as it started
life in London, and counting the generations mentioned, Mr Jennings would not have been far enough back, bearing in mind that R Whites started in 1845. I agree it used to be the best lemonade around,
but I believe the recipe is now different, and they no longer use sugar,
but various artificial sweeteners. They also used to use an artesian
well for their water (it's not called Spring Hill for nothing!), but this got polluted in the late 1960's, and they went over to mains water.
There was indeed a factory at Western Road, producing 26oz, 10oz, and 7oz minerals, -the various other drinks such as squashes and fruit juices coming from London
Kind regards
Dave
