Canada Dry Blackberry & Ginger Ale (355ml)
Popularised during the American prohibition years as it apparently made the perfect sweet mixer for moonshine. We can see the advertising for it now. "Canada Dry Blackberry Ginger Ale; so good it masks the god-awful flavour of back-street moonshine made in a rusty distillery constructed from old car parts". They probably don't use that in their marketing these days, however true it remains.
