Wine Grenade

Wine Maturation - Redefined.

What is the Wine Grenade?

The Wine Grenade is a simple, standalone tool designed to put the process of micro-oxygenation within reach of all winemakers. It’s easy to use, requires no installation, and removes the cost and complexity from maturing wine.

Winemakers simply activate the device, place it atop their tank, and the Wine Grenade takes care of the rest.

The Technology

Micro-oxygenation is a technique used by winemakers to mimic oak barrel maturation and get good wine to market quickly. It's a well accepted technique used in many wines consumed today.

Winemakers have expressed frustration at the cost and inconvenience of existing micro-oxygenation systems preventing them from treating as much of their wine as they’d like to. We invented around this issue by completely removing installation costs and by making our technology accessible to all. We have changed micro-oxygenation from a capital expense to an operational one.

Efficacy studies undertaken alongside winemakers in New Zealand and the United States have shown the Wine Grenade’s patented oxygen diffusion system to be more effective than alternative methods. Winemakers also benefit from remote monitoring and real-time data capture and analysis. They now have greater insight into the development of their wine and greater control of the maturation process.

Our Story

The development of Wine Grenade's product has been shaped by New Zealand's leading winemakers. Their insight and expertise is leveraged throughout our user research and User-Centred Design process. The result is a device which is perfectly suited to meet our customers' needs. Wine Grenade's highly skilled engineering team continues to iterate the product design as our understanding of the Wine Grenade’s role in a winemaker’s toolkit evolves.

Commercial trials at Sacred Hill Wines in Hawke’s Bay proved that the Wine Grenade works exactly how winemakers need it to work. Further field trials in Napa Valley have demonstrated that our approach is simple and effective, yet adaptable to different winemaking styles including; grape varietals, climatic differences, oxygen dose rates, and length of maturation programme.

Hear from Chief Winemaker (Tony Bish) and Head of Red Winemaking (Jenny Dobson) from Sacred Hill Wines in Hawke’s Bay, as they discuss their experience using the Wine Grenade.

Wine Grenade is at the leading edge of micro-oxygenation technology. Our intensive research and development programme has involved engineers and researchers from NZ Government-owned Plant & Food Research, and scientists from the University of Auckland's Wine Science Programme and NZ Product Accelerator group.

The Wine Grenade team have received support from a number of funding bodies including research and development grants from Kiwinet and Callaghan Innovation. Our desire to be at the forefront of wine technology has been recognised in New Zealand's Hi-Tech Awards, New Zealand Innovator Awards, and at the University of Auckland's $100k Entrepreneurship Challenge.
