I've been asked by a reader of the blog (Jason, from Tasmania in Australia) for help identifying (and possibly sourcing) a blend called "Caledonia Medium".
It was the favourite blend of Jason's late Uncle for many years and he used to get it from Herbert Love in Queensferry Street (now closed unfortunately).
If anyone recognises the name and can suggest a possible replacement source, please let me know and I will let Jason know.
I'm guessing that if Caledonia Medium wasn't blended by Herbert Love themselves, it might have been a re-labelled bulk blend from one of the major suppliers. If this is the case, it might be available elsewhere under a different name.
Thanks in advance for any help.
