Over fifty percent of Australian wine exports now leave our shores in big amounts for packaging in market – up from just 20 per cent decade ago.
With this in mind, Wine Australia funded a task with all the flexibag exploring the bulk transport process, and whether the choices wine companies make have sensory or chemical influence on the wine during or after transit.
AWRI researchers Simon Nordestgaard and Eric Wilkes as well as wine sector collaborators tracked multiple million litres of wine bound for your UK over 15 months and also the outcome was very positive.
They found that deciding on a tank, shipping route and filling temperature essentially had no impact. No taints were observed and, as outlined by packaging facilities, the pick-up of taints during bulk transport has not been a challenge for several years.
The absence of any taints ‘is likely a evidence of the management strategies created by the largest freight forwarders/flexitank suppliers servicing the Australian wine sector’, Dr Nordestgaard said in the final report.
‘These measures include container sorting, container lining and Oil which provide a final stage of product protection. Whenever engaging a whole new freight forwarder/flexitank supplier it is strongly recommended to make certain that well-conceived taint avoidance strategies/materials will be in place together with appropriate evidence of performance.’
Dr Nordestgaard ran the trials in 4 batches, each involving around 11 containers full of 24,000 litres of wine, with the type of tank (ISO tanks or flexitanks), shipping route dexopky84 filling temperature (8°C or 19°C) since the 3 variables. Chardonnay was the wine associated with preference, as it is the white variety exported from the greatest volume towards the UK. A few containers of Shiraz-Cabernet Sauvignon blend were also monitored.
Normally, ISO tanks ended in marginally higher retention of several chemical contaminants, but also in tastings experienced winemakers did not consistently like the wines shipped in ISO tanks.
The path taken, and whether the wine was flexibag services through a hub port (e.g. Malaysia) or stayed on board the identical ship, had no real impact. Schedules varied, and in some cases routes involving trans-shipping were actually quicker because there were fewer other stops.
