I know, there are thousands and thousands of sources nowadays but recently I have found some very interesting videos realized by Klaas de Jong who has combined his passion for wine with his profession as filmmaker realizing greatly professional and informative videos named Wine Masters.
He involves winemakers as well as wine experts (such as MW) who are able to provide us with a wider perspective of each territory.
I find them very useful also as Wset Diploma Student to get those details you cannot find on handbooks.
I seriously recommend them (The full series can be rent/bought on iTunes, Amazon, Google Play, Vimeo on Demand & on www.winemasters.tv).
Have a look here: this is a trailer:
