My passion for the Douro and Porto

I’m James Mayor, wine writer and founder of Grape Discoveries. My writing focuses on the Portuguese wine industry and sustainability. I am currently interviewing leading Douro wine producers and winemakers (see the in the news and videos section of this website).
Before falling in love with Portugal I lived in England and France, where in my twenties I worked as an intern on a famous Medoc wine estate, beginning a long association with the wine industry. In Paris, I owned an art gallery, later working as a consultant for the wine and spirits division of luxury goods group LVMH.

Douro Valley

Today I live in the magical city of Porto and spend as much time as I can in the Douro Valley. Many wonderful people in the region have been incredibly welcoming, and over the years I have been privileged to become an ‘insider’.

Grape Discoveries was born from my desire to share Douro wines unique context, to show where physical and cultural terroir meet to produce innovative wines, often world-class.
A talented winemaker is like a great artist, creating in a fertile space between agriculture and artistic invention. Winemakers are fascinating people to talk with!  I have curated a textured experience for you to discover the Douro. We explore my favorite hidden corners of this beautiful wine region, visit wineries, talk to authentic people, taste exceptional wines and see how vineyards are adapting to changing climate conditions through sustainable farming.


Porto today is at the center of the international wine and food map. Our city tours are more like a conversation with friends than a conventional tour. You are immersed in the sensory Portuguese culture, a wealth of marvelous aromas, flavors, sounds and sights.
“James Mayor has to be the best Guide we have ever traveled with and the places we visited were second to none.”
