Located in the Sutton Mountains of southern Quebec, the Chapelle Ste. Agnès vineyard was established in 1997 by Henrietta Antony, a Montreal antique dealer. The vineyard is named after a stone chapel built several years earlier on the same site and consecrated to St. Agnès, a thirteenth century Bohemian saint. The vineyard has over 7000 vines and is focused on the production of ice wine and other dessert wines.

To oversee production, Mrs. Antony enlisted the help of Christian Barthomeuf, one of the pioneers of viticulture in Quebec who helped found the Domaine des Cotes D'Ardoises in Dunham, Quebec. In 1986, Christian won an international gold medal for a Quebec wine. In recent years, his focus has turned to dessert wines and ice cider.

In 2006, in just its’ first year of entering wine competition; Chapelle Ste. Agnès had won a silver award (best in class) for its’ Gewürztraminer icewine 2002 and a bronze award for its’ Vidal icewine 2002 at the very prestigious International Wine and Spirit Competition in London, England.

John Antony, Mrs. Antony's eldest son, is actively involved in the vineyard. He works under Christian's direction, and has completed his viticultural studies at the University of Guelph in Ontario.

The vineyard is built on a steep hillside, with massive stone walls supporting 18 terraces. Thousands of tons of stones and gravelly soil were used to create the vineyard. The rows of vines follow the gentle curve of the hillside, creating a veritable amphitheatre.

There are advantages to producing ice wine in southern Quebec, but the cold winters also bring about some challenges. In the production of ice wine, a careful balance must be attained between a climate that is cold enough, and a growing season that is long enough.

The Chapelle Ste. Agnès vineyard's southern exposure, 30 degree slope, imposing stone walls, ideal altitude above the valley floor, gravelly soil, amphitheatre-like bowl and the two ponds at its base have created a unique endoclimate. During the day, the vineyard is noticeably warmer than the surrounding area, and due to the retention of heat by the stone walls and gravelly soil, the vineyard is also warmer at night. The vineyard's unique endoclimate extends the growing season, which allows the grapes the time they need to attain the level of sweetness required for superb dessert wines. At the same time, the vineyard's climate is cold enough to consistently produce high quality ice wine every year.

The vineyard is largely cultivated by hand. The vines are planted close together in an Alsatian manner. To enable the vines to survive the harsh winter, most vintners in Quebec cover their vines with earth, a technique known as hilling. At the Chapelle Ste. Agnès vineyard the vines are spared the stresses of hilling and de-hilling. Instead, every autumn each vine is individually wrapped in a coat of insulating material. In addition, Chapelle Ste. Agnès is an organically managed vineyard - with the exception of 2007 when a synthetic fungicide treatment had to be utilized.

To make the icewine, the grapes are hand-picked on the vines in the winter. Much effort and sacrifice is expended in the vineyard to ensure ultra premium quality grapes and wine. For instance the pruning of grape clusters to increase the quality of the remaining grapes and taking off the laterals which deplete too much energy from the plant in its' grape production. The wines also stay in the vats much longer than normal.

The first harvest was in 2001 and was bottled in September 2003. The vineyard is currently selling several ice wines, vin de paille and vin doux naturel, as well as a limited amount of white table wine.
