Cottonworth Farm near Andover is located in the Test Valley and has belonged to the Liddell family since the 1880s. It originally covered 800 ha and was used for fishing as well as arable and livestock farming. More recently it has been converted into an organic arable farm, and in 2005 the first small vineyard (1 ha) was planted.
There are now three vineyards on the estate and the intention is that these will be further expanded in the future. Vines planted are Chardonnay, Pinot Noir and Pinot Munier, with the intention being to specialise in producing high-quality sparkling wine. The Pinot Noir clones are predominantly Champagne Pinot, chosen for their high yields, low colour and disease resistance. There are some Burgundy Pinot Noir clones which are mainly used in the production of Cottonworth sparkling rosé.
Having outgrown their original winery facilities, pressing and vinification now takes place at Hattingley Valley winery under the direction of Emma Rice. Some Cottonworth fruit is incorporated into Hattingley Valley wines and the remainder becomes Cottonworth sparkling wines.
Uniquely for an English wine producer, Cottonworth also produces still wines from Burgundy. Hugh Liddell had studied and worked in this French wine region so had a good understanding of how best to circumnavigate potential pitfalls. Funds for purchasing vineyards in Chassagne Montrachet (les Lombardes) and St Aubin Premier Cru (les Perrières) became available following the sale of 38 ha of Cottonworth Farm land to Nyetimber.
In 2014 the Cottonworth Brut Rosé 2011 was awarded a silver medal at the Decanter World Wine Awards.
