Paradox of old vineyards: Part five of five of a serialized report on old vines in South Africa

By Petri de Beer

As the wine industry transitions into an era where older vineyards will constitute the majority of vines in our industry, it is crucial to assess their role in shaping the sector’s future. In regions such as Stellenbosch, over 50% of vineyards are already older than twenty years, with Paarl and the Swartland not far behind. This shift necessitates a deeper evaluation of the position these older vines will occupy within the industry and their impact on ensuring the long-term economic sustainability of South Africa’s wine sector. Understanding their potential contributions and challenges will be essential in securing a resilient and thriving wine industry for the future.

If we look at the interplay of new vineyard plantings vs old vines are characterized by an inverse relationship where new vineyard plantings often decline during low-profit periods as we are currently seeing, and conversely, there is a surge in plantings during high-profit cycles, when producers are able to adapt to customer preferences for specific wine grape cultivars.

During low-profit cycles, the wine industry faces a significant challenge in terms of investment in vineyard renewal. The economic constraints of these periods often lead to a lack of investment in replacing aging vines, as the immediate return on investment of planting new vines appears uncertain. Vineyard owners and managers may defer replanting decisions, choosing instead to maintain existing vines despite their declining productivity and increasing maintenance costs. This reluctance to invest in vineyard renewal during low-profit periods can result in a gradual decline in the overall productivity and quality of wine grapes, thereby further exacerbating the industry's profitability challenges. Although as shown throughout this series these risks can and are being mitigated and managed.

Especially those cultivars that are in high demand among consumers. This proactive approach to vineyard replanting aims to capitalize on market trends and consumer preferences, thereby maximizing profitability.

However, the economic sustainability of old vineyards presents an intriguing paradox. While new plantings surge during high-profit cycles, the older vineyards often continue to play a crucial role in the industry's profitability. These mature vineyards, despite their age, frequently maintain or even increase their economic sustainability in high-profit periods. The reasons for this include the established reputation and quality of wines produced from older vines, which command premium prices in the market and in some cases the maintaining of profitable yields. Furthermore, the cost of maintaining these vineyards, while higher than that for newer plantings, is often offset by the premium pricing of the wines they produce.

The narrative that emerges from this dynamic is one of strategic economic considerations within the wine industry. The primary motivation for replanting vineyards with new, consumer-driven grape cultivars is to maximize profit, particularly in response to favorable market conditions. This strategy, while effective in the short term, must be balanced with the long-term sustainability of the industry by balancing input costs with the return on investments realized by producers. Ensuring that older vineyards continue to be economically viable and productive is essential for maintaining the overall health and diversity of the wine sector.

The stabilizing influence of older vineyards within the industry cannot be overlooked. Their ability to maintain consistent yields and produce high-quality grapes provides a crucial foundation for the sector. This stability allows a portion of the industry to adapt more dynamically, facilitating quicker turnarounds and the replacement of cultivars in response to evolving market trends and consumer preferences. By ensuring a reliable base of production, older vineyards help mitigate industry risks and safeguard against the volatility of boom-and-bust cycles, contributing to the long-term resilience and sustainability of the wine sector.

So what lies over the horizon for the South African wine industry? Predicting the future of the wine industry is a complex task, filled with uncertainties. However, we can look at current trends in international wine production provide some insights into how consumer behavior is evolving and how the industry must adapt.

Globally, the wine consumer landscape is changing. Traditional wine-drinking populations are seeing a gradual decrease in per capita consumption. While these consumers are willing to spend more on wine when they do purchase it, the overall volume they consume is declining. This trend suggests a shift towards premiumization, where consumers opt for higher-quality wines but in smaller quantities. Simultaneously, the industry faces challenges in tapping into the needs of untapped consumer bases in developing regions. Despite the large potential market, penetrating these new demographics has proven difficult due to varying preferences, economic conditions, and cultural factors.

Economic pressures further complicate the picture. Consumers worldwide are experiencing financial strain, which impacts their purchasing decisions. Maintaining a robust market for entry-level wines is becoming increasingly challenging as cost-conscious consumers may limit their spending or switch to alternative beverages. This economic reality contributes to the decrease in vineyard hectares, poses significant challenges for the industry's future.

The current scenario of decreased vineyard hectares and decreased consumer demand necessitates finding ways to maintain these older vineyards for longer periods. This is crucial not only for sustaining production levels but also for leveraging the unique characteristics that older vines can bring to the wine. The industry's challenge lies in maximizing the positive traits of these older vines while mitigating the risks associated with their age.

At the core, there needs to be a reassessment of how the industry defines old vines and their current contributions to the industry as to be able to make decisions of when they have to be replaced.

More importantly, there must be consideration to their future role and the expectations of these old vines, ensuring that this aligns with the realities in the vineyards. As highlighted in this series, age distribution of vines alone is not a sufficient indicator of producer or industry sustainability. Instead, there should be adopted a more holistic approach, taking into account plant health and the economic sustainability of the vineyard.

By embracing a more comprehensive perspective, the industry can make strategic, well-informed decisions that align with both its immediate needs and long-term objectives. Ultimately, a balanced approach, one that integrates vine health, economic sustainability, and market dynamics, will strengthen the industry's resilience, ensuring its ability to adapt, thrive, and consistently deliver high-quality wines in an ever-evolving landscape.
