Winemakers in France are seeking to combine cost cutting with greener farming, according to organisers of the country's biggest wine equipment fair.

"The two major trends this year are cost cutting and using durable farming methods," said Vinitech organiser Frederic Espugne, during this week's bi-annual fair in Bordeaux.

He described greener winemaking practices as 'a marketing necessity' for attracting today's consumers.

Local winegrowers visiting the trade fair said greener products included small 'soil turners' to replace pesticides, which have tripled in price.

Reducing energy costs using solar panels and lighter bottles were other options. Saint Gobain, one of the leading bottle suppliers, launched its Ecova range of lightweight bottles, which cost the same as a normal bottle but weigh 90g less.

Vinitech 2008 recorded around 40,000 visitors, up from 38,000 in 2006.
