How the COVID situation will accelerate technology innovation in NZ wineries

With second waves affecting many major wine growing regions around the world, it seems highly unlikely that New Zealand will relax border and quarantine rules anytime soon. Wineries large and small are expecting severe skill shortages – both manual and highly skilled labour – and are looking at ways to prepare for a successful harvest and processing season.

We speak with Roger Johnson, National Sales Manager, Food and Water Division, Alfa Laval New Zealand, about the impact on the 2021 vintage and which technology areas offer the greatest potential for productivity gains.

 

Why is the COVID situation affecting NZ wineries?

Winemaking is an industrialised process that also involves skilled craftsmanship and art. This means not only seasonal labour, but the NZ market at least historically draws on a global skill base from the other major wine growing regions such as North and South America, South Africa and Europe. With the current travel restrictions in place, it’s harder to bring technical specialists to New Zealand for the next harvest and that affects wineries across the board.

 

What are the technologies that vineyards are looking at for productivity and automation?

I’ve seen media commentary looking at machine harvesting as an obvious area, especially as it’s difficult to justify two weeks of quarantine for a six-week harvest season for fruit pickers (e.g. Rural News).

But it’s not the only technology that local winemakers should be looking at. Efficiency and productivity gains can be found in many other areas of harvest and vintage.

Take for example grape juice extraction. Most local wineries are still using soft press technology. Using a press to extract the juice is not only more time consuming but a multi-step process with extensive labour requirements. That’s why vineyards in other parts of the world have invested in decanter technologies which involves fewer resources and steps with better results in juice clarity.

 

Why is it a good time to invest in new technologies?

Vineyards are under a lot of pressure at the moment but as they say, every challenge is an opportunity. I think we will look back and recognise that the unique situation with the pandemic has been a catalyst for innovation in the industry. In contrast to many other wine-producing regions, New Zealand has a lot of potential left for growth, due to our ideal climatic conditions and proximity to Asia.

My advice to local winemakers would be to do their research on new technologies and equipment available to the industry today. For example, read up on the international studies that compare soft press with decanter technology for grape juice extraction and see how the results stack up.

The other recommendation is to go with a technology partner with a strong local market and service presence. The travel restrictions apply also to technical specialists, so it’s never been more important to have people on the ground. Alfa Laval has a major service centre in Hamilton and offers field service support by some of the industry’s most experienced technicians across the North and South Islands.
