The impact of climate change on wine investment

  • Environmental considerations are the number one reason why UK investors choose to invest in fine wine.
  • Fine wine itself is facing the effects of climate change such as reduction in yields.
  • Scarcity can drive demand and prices higher, but also lead to the broadening of the fine wine market.

Climate change and environmental considerations are the number one reason why UK investors choose to invest in fine wine, according to the results of our Global Wealth Manager Survey 2023. Over half (54%) of our respondents cited fine wine’s low carbon footprint as a key reason for adding it to their portfolio.

While there is a strong case why fine wine can be considered an ESG investment that is a good for the environment, fine wine itself is facing the impact of climate change. Like all agriculture, viticulture is at the mercy of the environment, making climate change a pressing issue for wine investors.

Changing weather patterns affect wine quality and quantity – two of the main factors that can make an investment profitable.

How changing weather patterns affect wine quality and quantity

In general, climate change can lead to alterations in grape ripening cycles, water stress, diseases and pests, and can affect berry size and composition.

Rising temperatures can cause early ripening, potentially disrupting the balance of sugars, acids and tannins – factors crucial for the quality of the wine and its ageing potential. Meanwhile, drought and irregular rainfall can lead to excessive water stress in the vines, affecting fruit development. Warmer temperatures can also bring new pests and diseases to regions previously unaffected, while heatwaves can cause grapes to sunburn, reducing yield and quality.

For instance, in 2023, two of the main fine wine producing countries, France and Italy, faced diverse weather patterns. France’s 2023 wine harvest projects between 44-47 million hectolitres, benefiting from potentially strong yields in Champagne and Burgundy. Italy, however, might see up to 14% reduction in yields due to extreme weather, marking it among its smallest harvests.

What does this mean for fine wine investment

Smaller harvests lead to reduced supply, and assuming that demand remains constant or increases, prices tend to rise. When news of a small harvest breaks, especially from a reputable wine-producing region, it can create a buzz in the trade. Buyers and collectors might perceive wines from that harvest as more valuable or unique, driving up demand and, subsequently, prices.

Moreover, a smaller harvest doesn’t necessarily mean reduced costs. Wineries still have to maintain vineyards, pay labour, and cover all production expenses. With fewer bottles to sell, the cost per bottle increases, which can result in higher prices for the consumer.

Supply and demand

This is a particularly pertinent question for regions, where scarcity is the main driver behind their investment appeal such as Burgundy. A recent example was the 2021 Burgundy En Primeur campaign, which saw drastically low volumes. The Bourgogne Wine Board (BIVB) pointed to a crop of 900 to 950,000 hectolitres, representing about 50% of a normal year and 2/3 of the average in recent years.

As a result, allocations were low and release prices were up 25% on average. This stimulated demand for older vintages at comparatively low prices, such as 2012, 2014 and 2017, as examined in our Q1 2023 report.

Overall, climate change can create scarcity in the market, pushing the entry point into some fine wine regions higher.

The broadening fine wine market

The rarity of some wines is leading buyers to also consider alternatives from other regions, impacting the size of the market. Today there are more fine wine investment opportunities than in any other point in history.

Changing weather patterns have also led to the emergence of new wine producing regions. For instance, England is now producing award-winning sparkling wines, due to warming temperatures. The country is still a niche player in the investment market, but some brands such as Nyetimber and Gusbourne Estate are making waves.

Climate change is reshaping the fine wine market, with some of the traditional regions forced to adapt their strategies. It is more than an abstract global concern; its palpable effects are shaping the fine wine industry, from agriculture to investment.

How Climate Change Affects the Value of Fine Wine

The greatest risk for many investors today is – undoubtedly – the climate crisis. Each year the planet warms by 0.018 degrees Celsius[1]. And the past six have been among the hottest since records began. The resulting floods, fires and changing biodiversity are impacting nearly all asset classes and investment types. By 2050, climate change is anticipated to restrict global GDP by 14%[2].

For investors in fine wine, the rising heat could signify the end of an era for some of the greatest flavours, adding further scarcity to valuable bottles. On the other hand, the changing temperatures could offer interesting opportunities elsewhere.

In this article, we’ll uncover the major threats and opportunities for fine wine investors.

Scarcity will make much-loved bottles more valuable

Vineyards across Southern Europe and wine regions of North America are facing an uphill battle trying to mitigate the effects of climate change. In August 2022, an unprecedented hailstorm tore through Châteauneuf-du-Pape vineyards in France. The 120 mile-per-hour wind destroyed up to 90% of the vines in some of the most celebrated plots. So extreme was the storm that one vineyard owner described the scene as ‘completely shredded’ and ‘not a leaf is left'[3].

On the other end of the spectrum, extreme heat waves combined with drought in the summer provoke catastrophic forest fires. While only a small number of vineyards are caught up in the blaze, the resulting smoke can disrupt the delicate flavours and quality of the wine. Smoke taint – the ashy taste that lingers – can render entire harvests useless, leaving assets stranded. Even prized and world-famous regions like Bordeaux are feeling the painful financial impact.

It seems inevitable that many of the most-loved wines will become less and less available in the future. What this means for investors is that already-rare bottles are likely to become even more scarce and sought-after. Fine wine is already a limited and depleting asset, which climate change exacerbates. What’s more, as hungry new collectors enter the market, demand could even further outstrip supply, further raising the value of fine wine.

What’s more, according to 2021 data from Knight Frank, the average fine wine investment has returned a staggering 127% over ten years. Sticking to the strategy almost always pays off.

New flavours may be hard for investors to stomach

Even for regions without droughts or forest fires, climate change can seriously impact the flavour of wine. This is because the lack of water irrigation, combined with heat waves creates more sweetness and less acidity in the grapes. To avoid the wine becoming too sweet, producers may need to harvest early, which risks missing out on characteristic and valuable secondary flavours.

Not only could iconic wines now start to lack their defining volume, but the added sweetness could mean different varieties taste more alike. For wine lovers, who may enjoy certain brands or pride themselves on detecting notes, this development could be hard to stomach. There is a serious investment risk that future bottles could lose value, compared to their ancestors.

To avoid this cultural and financial damage, some regions are now lifting regulations to allow irrigation. In August 2022, for example, the Institut National de l’Origine et de la Qualité gave special dispensation for three sites in Bordeaux to water their vines. What this means for investors is still unclear. Depending on the success of regulations and irrigation systems, future harvests may yet retain their distinctive taste and value.

Another intriguing development triggered by climate change is the renewed focus on hybrid grapes. As famed vineyards look to adapt and mitigate against extreme weather, producers are working side-by-side with scientists to create more resilient grapes. While many critics remain sceptical, hybrid grapes could help vineyards restore some of their former glory..

Exciting investment opportunities are entering the scene

There are not many silver linings to the catastrophic climate situation. However, for investors in fine wine, there is a unique and exciting opportunity to buy new varieties early. As the planet warms, new terrains are opening, in previously unthinkable places.

Incredibly, vineyards are popping up in the UK, Belgium, Norway, and Sweden. In the UK, the wine real estate market is enjoying unprecedented growth, with land selling for £25,000 per acre[4]. English land dedicated to winemaking has more than doubled in the past eight years and looks set to continue[5]. As increasing numbers of producers and investors snatch up these pockets of land, it seems likely that the British wine scene is about to mature. Sparkling wines in particular, such as those produced in Sussex are exploding in popularity, with some critics describing the taste as comparable to Champagne. As of July 2022, sales of English and Welsh wine have surged by 69% from 2019[6]. Whether this boost will translate over to the fine wine market has yet to be seen, but with the warmer climate, British bottles could prove to be an interesting investment opportunity.

Vineyards with a sustainable focus look promising

Of course, the impacts of the climate crisis go far beyond the physical weather changes. Consumers are increasingly looking at the sustainability of their products too and thinking about how their money affects the planet. According to 2022 research, 48% of US alcohol drinkers say that they’re more likely to buy bottles if they see the company has sustainable or environmental initiatives[7].

In many ways, fine wine investments are already good for the environment, which is good news for the market. And it seems that those vineyards with extra sustainable initiatives in place could be even better positioned to capitalise on this trend.
