Bottled History: The Enduring Legacy of Portugal’s Oldest Wine

The Enduring Legacy of Portugal's Oldest Wine

Rich and sweet, it has been said that Port Wine ‘makes every meal an occasion, every table more elegant, every day more civilized.’ – Peter Lanberg, Wine Critic. And there is no better place to discover Portugal’s oldest wine and its intriguing history than in its birthplace, the breathtaking Douro Valley.

Here, as you meander the vineyards and explore historic wine cellars, there is one famous producer of Port Wine that takes centre stage – Sandeman. Famed for its exceptional quality, taste and innovation, throughout its history Sandeman has played a pivotal role in the promotion and popularization of Portugal’s oldest wine.

We had the pleasure of talking to Luís Sottomayor, Sogrape Head of Winemaking for Douro & Port Wines, who tells us that it “all starts in nature”. Hear about Sandeman, the importance of the grapes, how the brand stays current and pick up some Port Wine tasting tips.

As well as being renowned for its distinctive flavours, one of the most recognizable features of the Sandeman brand is its ‘The Don’ logo, which was created in 1928. The logo depicts a silhouette of a caped man known as the ‘The Don,’ inspired by the Spanish caballero and the Portuguese students, thus reflecting the brand’s Iberian identity.

An industry leader, the company’s founder George Sandeman was one of the first wine merchants to brand casks with his initials and subsequently to label his casks with a unique branding. Sandeman was also one of the first Port Winemakers to label bottles and advertise its wines.


Port Wine boasts a fascinating history dating back to the 17th century in Portugal’s picturesque Douro Valley. Its origins are closely tied to England’s insatiable thirst for Portuguese wine, which led to significant trade relations between the two countries.

The close relationship between Portugal and Britain can be traced back to the Middle Ages when trade between the two nations began to flourish. Portugal, with its warm climate and fertile soil, led the way in wine production, drawing attention from British merchants and consumers.

Tensions however arose over trade imbalances and the terms of trade. Portuguese merchants were concerned about the British woollen cloth imports flooding the Portuguese market and causing harm to their domestic textile industry.

The Methuen Treaty, signed in 1703 between England and Portugal, was a historic trade agreement. It primarily benefited England by allowing for the importation of Portugal’s oldest wine at lower duties in exchange for English woollens. This treaty significantly boosted the Portuguese wine industry but came with economic implications and political consequences.


Shipping wine from Portugal to Britain involved long and treacherous sea voyages, taking several months. During the journey, traditional wines often spoiled or deteriorated, which posed a significant problem for wine merchants.

A key innovation in Port Wine’s development was the addition of wine brandy, a distilled spirit, to the wine. This practice, known as fortification, had the dual benefit of increasing the wine’s alcohol content (which acted as a preservative) and leaving residual sweetness in the wine. This made the wine robust enough to withstand long sea voyages without spoiling and made the taste more appealing to British consumers.

Today, Port producers use wine brandy during fermentation, rather than after completion, to sweeten and fortify the wine. So, the Port we know today is somewhat different from the original wine fortified 200-odd years ago, but this innovation played a significant part in the success of Portugal’s oldest wine.


Established in 1790 in London by a young Scotsman named George Sandeman, Sandeman quickly gained a reputation for producing exceptional Port Wines from Portugal’s Douro Valley.

Located in northern Portugal, the Douro Valley is today a stunning UNESCO-listed wine region renowned for its terraced vineyards that line the steep slopes along the Douro River. The region’s rugged terrain, Mediterranean climate, and schist soil create optimal conditions for grape cultivation.

In the 19th century, under the leadership of George’s sons, George Jr. and John, Sandeman expanded its presence in the Douro Valley, purchasing its own vineyards and estates. They became known for their innovative winemaking techniques, including the use of ageing cellars and blending to create distinctive Port styles. Throughout history, Sandeman has continued to thrive, becoming a global brand and industry leader of Portugal’s oldest wine.

“The Douro is a unique region,” says Luís. “Every nook and cranny has its particularities and special details, giving birth to fantastic grapes that produce different styles of wines, but always with extraordinary quality.

“Due to the experience and knowledge that we keep gaining through time, we know how to obtain the maximum potential of each plot and each variety.”


“The most important factor to making exceptional quality wine are the grapes,” Luís explains when asked about the company’s wine-making philosophy. “Sandeman has always looked for the best grapes, both in order to fulfil quality standards and, primarily to ensure consistency – a precious attribute in Sandeman’s portfolio which is combined with the blending expertise of the winemaking team.”

While Sandeman does own vineyards and quintas, the majority of Port Wine production in the Douro Valley involves a cooperative system. Many producers, including Sandeman, source their grapes from local growers and vineyards, as well as from their own properties.


The Sandeman brand is known for producing a variety of Port styles, including White, Rosé, Ruby, including LBV and Vintage Ports of course, and Tawny, with its Aged range being the subject to huge acclamation. These wines undergo different ageing processes and are blended to achieve specific flavour profiles, for which they are renowned.

“To create such diverse flavours, it all starts in nature,” Luís says. “The essence, again, is in the grapes. We have a deep knowledge of our grape varieties and which ones, according to where they are planted, best suit each style of Port.

“Once the wine is produced, per our experience and long years tasting and blending, we know how to work and age them while keeping faithful to the house style.”


“Sandeman has always been an innovative, trendy, and contemporary brand,” explains Luís. “We’re aware of consumers’ preferences and expectations. Whilst always offering top quality and highly awarded wines – namely our Aged Tawnies range – Sandeman has also evolved through generations.

“We apply the knowledge, heritage and expertise that has been passed on from winemakers and master blenders to the next generations and take advantage of new and more modern winemaking techniques. We respect the past, but we’re always looking to do things better!

“Sandeman has also come a long way, and we are dedicated to evangelizing the Port Wine perception and consumption. This has been done through promoting its different styles in a more approachable way, calling for new and younger consumers, while presenting new ways of enjoying – cold, chilled, with ice, mixed with other drinks and even on the go with the newest ready-to-drink Portonic. We also create new wine references to conquer new tastes – Sandeman Beat is a good example here.”

If you’re passing through Porto you cannot leave without tasting the elixir that gave it its name. Also known as the Invincible City, or ‘Cidade Invicta,’ during the 19th Century Civil War, Porto successfully resisted a brutal siege for 18 months. After this show of strength, it proudly gained its nickname.

Just outside the city, you’ll discover the numerous wine cellars of Vila Nova de Gaia, where Sandeman is one of the most prominent associated names. Here they age and store their Port Wine. Walk along corridors of casks, get to know their Tawnies and Vintages and taste some of their finest.

When asked for some tips, Luís tells us “To taste Port Wine is not much different than still wines. A kind of surprising tip for some is to drink it chilled, on the rocks or even by mixing it with ice, tonic water, and lemon – this last one is to be done more with the whites and rosés.

“In a more serious or formal tasting, we must observe colour first, then the aroma and taste. While tasting it will be evident the higher level of alcohol, but if served at the correct temperature, it will be a quite pleasant experience overall.”
