What influences the characteristics of a wine


Temperature, sunlight, altitude, degree of slope of the soil, exposure to wind, and proximity to rivers or the Ocean are factors that affect the maturation of the grapes and, therefore, the production of wines and their characteristics.



Here the winemaker also plays an equally important role in how to manage the vineyard and when to harvest.

Despite the small land surface (35,500+ square miles), Portugal is a kind of microcosm in which there is a Mediterranean climate with or without maritime influence in the mainland, in the Madeira archipelago a sub-tropical climate and in the Azores, once again, Mediterranean but much more pleasant.

Added to this are several topographic conditions. There are more mountains in mainland Portugal to the north and northeast with plains to the south.

For example, vines planted at an altitude receive a greater difference in temperature throughout the day, so grapes are richer in color and tannins.


Portugal is bathed by the Atlantic Ocean on all its south and west sides. Sea winds act in a refreshing way in the vineyards along the coast.

Many of the wine regions are crossed by rivers, some even get their name from it – Douro, Dão, Tejo. Here the proximity to water acts in two ways. First, it makes the temperature more stable and long-lasting.


Second, it also acts as a mirror, reflecting sunlight, intensifying its presence in the vineyards creating a more ripe grape.


As for the soils, they vary between granitic, schist, clay, sandy, and of volcanic origin on the islands. Adding to this the diversity of grape varieties, around 250, we now have a country with the appetite to produce almost all styles of wine!

Based on all this, Portugal has 29 delimited designations of origin for the production of wines plus 14 geographical indications.

During the Desenrolhar Vinhos Portugueses you will live 14 stimulating days traveling through mainland Portugal and get to know the wine producing regions and their main grape varieties.

Imagine yourself arriving home in three weeks, after buying a Portuguese wine and feeling confident and even excited about your choice.

Why did I create this challenge?

I know wine is complex and can be scary for you and I want to help change that.


After years of teaching about Portuguese wines plus the contact I have at events with thousands of wine lovers like you, I feel that most people see wine in an intimidating way and find it confusing.


There is a lot of insecurity… the fear of giving the opinion and not being the “correct”, the question of choosing between two bottles.


Wine is indeed a unique drink and yes, it is complex, however I believe that is where the power of attraction it exerts lies.

What you need to know to feel confident when choosing and drinking Portuguese wine, you will find in Desenrolhar Vinhos Portugueses – 14 Days Challenge.
