I've had a chance to spend some time on Tenerife to discover how little-known and underappreciated are wines from the Canary Islands🏝️. To learn more about them and their unique story, many local winemakers and sommeliers pointed me to this e-book (free and safe to download).

It covers everything from the history and how the vines stayed phylloxera intact, to the specificities of each Canarian DOs and local varieties. It also mentions remarkable producers whose wines are often easier to find abroad than where they originate.
I find it a great resource for everybody - if you need precise information for your Spanish wine study or tips for your next travel, this book has it all!
