According to the latest figures (2015) released by the wine standards branch of the UK government’s Food Standards Agency the average annual production of wine in the UK has increased from 3.02m (bottle equivalent) to 5.06m in 2015. A fascinating statistic indicates that wine production by 2020 is predicted to surpass 10m bottles.

Currently there are approximately 502 commercial vineyards, with some 133 wineries.

Generally the hectarage of vines planted in the UK has doubled in the last 8 years and is set to continue growing by a further 50% to around 3000ha (just over 7400 acres) by 2020.

In the wine trade papers and Sunday supplements much has been written about the success of the multi-award winning English sparkling wines produced around Kent, East and West Sussex and Surrey, where the greatest concentration of vineyards is located.

Few people are aware that a recent addition to the number of wine growing areas can be found in the beautiful rolling countryside of Monmouthshire in South Wales.

White Castle Vineyard is owned and run by Robb & Nicola Merchant, situated in the village of Llanvetherine, close to the towns of Abergavenny and Monmouth. It is dedicated to producing a variety of quality welsh wines using first class viticultural practices.

Their 5 acre (2.02 ha) vineyard is planted on a gentle south facing slope, ideally situated for vine cultivation and ripening grapes for Welsh wine.

The Merchants welcome visitors to experience the beauty and tranquillity of the rural setting of their vineyard. Additionally, their award winning quality Welsh wines are available for purchase from the Cellar Door.


Having purchased the 12 acre small holding at Croft Farm, Llanvetherine near the market towns of Abergavenny and Monmouth in 1995, Robb and Nicola Merchant converted the former milking parlour into their home, a year later. It was not until 2008 when their joint dream of owning a vineyard started to become a reality. That year, the 5 acre (2.02 ha) gently sloping, south facing field was purchased, soil tests were performed and following intensive research into vineyard management and selecting the most suitable grape varieties, the proprietors ordered their first vines in November 2008.

In May 2009, a contractor was hired to plough the site and to aid the planting of some 4000 vines, the varieties of which included: Pinot Noir, Regent, Rondo, Seyval Blanc and Phoenix. The following year, a supplemental planting of 800 vines of the Siegerrebe variety of grapes was added.

The vast majority of the 40 miles of posts and wire to support the vines were erected by members of the family-run business, who also added layers of mulch around each plant to retain moisture in the soil and help keep the weeds down.

To ensure their vision became a reality, Robb & Nicola attended Plumpton College, East Sussex to study viticulture, to equip them with the skills and expertise needed to produce quality Welsh wines.

From the initial planting, it took two and a half years until the first harvest came about in September-October 2011. Their efforts were soon to be rewarded, however, as the first harvest gained the vineyard Protected Designation of Origin (PDO) status from Wine Standards, of the Food Standards Agency, allowing the produce to be labelled ‘Welsh Quality Wine’. Additionally all their wines have Protected Geographical Indication (PGI) status.

The grapes were hand picked and pressed on the same day at the Three Choirs winery in Newent, Gloucestershire, resulting in red, white and rose wines which were sold from the White Castle Vineyard shop.

When the vineyard reaches full production, over the next few years it should have the capacity to produce 12,000 bottles of wine a year, including sparkling wines.

The Merchants are firm believers in the adage that quality wine making begins in the vineyard. For this reason alone, they carefully selected the varieties that they know would flourish in the vineyard’s soil and would produce grapes of the highest possible quality, given the micro climate of the vineyard.

The grapes are closely monitored all throughout their growing season and as harvest time approaches, the ripening grapes are carefully hand harvested and selected, then immediately transported to the Three Choirs winery for pressing to ensure all the freshness and fruity aromas are retained intact.

Depending on the type of wine being produced, the juice is fermented in stainless steel vats, with some undergoing a period of further ageing in a French Oak barrels to enhance the flavours.

The following varieties of grapes are grown at the vineyard:

Red Varieties

Pinot Noir Précoce
One of the most ancient and refined of all grape varieties. It is a classic red Burgundy grape for but these days it is also an important element of sparkling wine production.

One of the new generation red varieties, propagated for quality results. It will produce a medium bodied wine with excellent fruit and tannic balance.

Produces wines with very good ruby colour, fruity aromas and dark cherry flavours, producing a delicate, deep coloured red wine, with the style and overtones of quality classic red varieties.  

White Varieties

In character, similar to Sauvignon Blanc, aromatic and acidic.

Seyval Blanc
A successful hybrid variety, well adapted to UK growing conditions. It is well suited to oak ageing and can be used for still or sparkling wines. Single varietal wines offer the drinker crisp acidity, with a characteristic citrus element in its aroma and taste, as well as a minerality that some compare to a white Burgundy.

An intensely aromatic and sweet variety producing delicious small berried plum coloured grapes.
