I highly recommend you follow Dublin café owner Colin Harmon on Instagram, and in this short video he shows off all the Christmas gifts you can buy at his cafe – a master at coffee retailing.
I heard him speak a couple of years ago in Sydney, and he was fierce on the value of adding good retail to your mix if you sell specialty coffee – he said up to 25% (!) of their total sales come from this. The man is an inspiration in many ways – he also has a great book on running a profitable café.
