Best practice for recovery after bushfires

The recent devastating fires have burnt over 1000 hectares of Australia's vineyards and generated the longest and the most widespread period of smoke haze on record.
National and State organisations including Australian Grape & Wine, the Australian Wine Research Institute and Wine Australia as well as Regional Associations are providing information sessions and resources on how to deal with the challenges of damaged vines and smoke exposed grapes.
The following resources are not intended as a comprehensive list, further detailed information is available on the Wine Australia and AWRI websites:

Recovery of vineyards after fire a case study

Greg Horner of Mount Bera Vineyards in the Adelaide Hills has kindly shared his experiences in vineyard recovery following the Sampson Flat bushfire in 2015.

On 2 January 2015, the Sampson Flat bushfire roared through Mount Bera Vineyards in South Australia, burning all of the vines to varying degrees.

Greg owns and operates the vineyard and, after the fire, the main recovery advice he received was to completely remove the vines and start again. Greg chose a different path, one that not only saw him harvesting in the first year after the fire, but also resulted in a complete recovery much faster and more cheaply than if he had started from scratch.

Listen to the podcast here or download the PDF of the case study to hear more about the vineyard recovery approaches that Greg took.

Please note that this is one way to approach the vineyard rehabilitation process. More information on recovery is available via the AWRI website and in its recent webinar.

Options for managing fire damaged grapevines

Grapevines react to fire in several different ways and the extent and type of damage determines the best approach to treating
the vines. Some effects of fire are obvious, such as dehydrated leaves and burnt bark, but other damage can occur below the surface of the plant, i.e. radiant heat causes damage or death to the plant without obvious external damage.

NSW DPI Bushfire Hub

The NSW DPI has launched Bushfire Hub (pictured) containing information on:
•    the emergency bushfire response
•    a quick guide to natural disaster recovery assistance for primary producers
•    the primary Industries natural disaster survey – a simple online survey to record damage to primary production and animals from natural disasters such as floods, fires and storms
•    financial assistance
•    bushfire recovery, including information for viticulture.

Grapevine recovery from fire damage

Bushfires can have devastating effects on vineyards and their occurrence may become more frequent with the changing climate. When damage occurs, grape growers are unsure about determining the appropriate response.

Assessing grapes affected by smoke exposure for smoke taint

In the event of a vineyard being exposed to smoke, the most effective time to test smoke-exposed grapes is as close to the expected harvest date as possible.
Smoke taint analysis is available from the Australian Wine Research Institute, phone +61 (0)8 8313 6600 and Vintessential Laboratories, phone 1300 30 2242.


Smoke Taint in Wine Special Issue for the Australian Journal of Grape and Wine Research.

This 2011 Special Issue is a collection of papers that cover problems of smoke taint from the grape to the glass and provides insights into the chemistry and biology at play. Importantly, this knowledge not only provides options for evaluating the severity of smoke damage and its amelioration, but also raises important future research questions.
