A Monmouth vineyard will have raised a glass or two after a corking night at the London International Wine Fair.

Ancre Hill Estates won four silver and two bronze Decanter World Wine awards, it was announced at the event.

Owner Richard Morris said: "This was an improvement on 2012 with two additional silvers over last year.

"What is pleasing is the great consistency shown year on year. We are particularly pleased with the performance of our Pinot Noir, with these results making it the best performing red wine from England & Wales in 2013.

"This was our first accredited biodynamic wine. This is another plus for the developing Welsh Wine Industry."

Ancre Hill is just one of the vineyards across Monmouthshire and beyond opening its doors to the public this week.

A programme of activities and special promotions, including tours and wine tastings, is being run to celebrate Welsh Wine Week.

Supported by the Welsh Government, vineyard owners have produced a Wine Trail Wales leaflet to encourage wine tourism and launched a new website – http://www.winetrailwales.co.uk">www.winetrailwales.co.uk – to raise the profile of the blossoming industry.

Minister for Natural Resources and Food Alun Davies said: "It is encouraging to see producers working together collectively to form a Welsh Vineyard Association.

"In terms of quality and potential, Welsh wine is certainly making a name for itself at home and abroad.

"I would encourage consumers to visit their local Vineyard during Welsh Wine Week and enjoy the fantastic produce they have to offer."

The Morris family planted the first phase of Ancre Hill vineyard in April 2006, with a further plantation in April 2007.

Ancre Hill, which produces 15,000 bottles of wine annually, is the only UK vineyard to grow Albariño, which originate in Galicia, Northern Spain, and further planting this month extends the vines to three acres.

Work is also due to start this summer on a commercial winery, which will be fully sustainable as it will have straw bale walls, a sedum grass roof and an ecological water treatment system.

Vineyard tours are being held twice daily at 11.30am and 3pm and, during Welsh Wine Week, there are free wine tastings.

The award-winning Parva Farm Vineyard at Tintern, which is run by Judith and Colin Dudley, is open from 11.30am to 6pm every day this week.

Group tours with tutored wine tastings can be booked in advance for days or evenings during the summer and the Dudleys also organise tours for hen parties.

Parva Farm has the oldest commercial vineyard in Wales, which was planted in 1979. It has 16 varieties of grapes, the main ones being Pinot Noir and Regent (red) and Bacchus, Muller Thurgau and Seyval Blanc (white).

A Tintern Parva white wine was served at a European Union summit meeting in Brussels when Britain held the presidency of the EU the vineyard's Tintern Parva Bacchus 2012 has just received a commended award in the International Wine Challenge.

The vineyard is on a site probably used by the monks of Tintern Abbey for their vineyard and overlooks the River Wye in an Area of Outstanding Natural Beauty.
