May old sake breweries have a « ball » hung under the eaves or roof at their entarnce.
It is made of ceadr branches.
Have you ever wondered about it purpose?
Actually it is a kind of « timer »: the cedar will dry and change colour and give the brewers indications not only time elapesd but also on climatic conditions!
Similarly, in England old pubs and beer breweries hung a bush under their eaves for the same purpose.
On a similar note, winegrowers in the Bordeaux area still plant roses at the end of each vine row to check the weather and especially the event of mould forming!
