The Upper Chester is the northern part of the valley. This is where the bulk of Brunanter olives are grown. Olive farms first sprung up in the 1660s, since local farmers found the land very suitable. Here 6% of Brunant's wine is produced, but the quality is not as high as in other areas of the valley.
The Kleinebeek is a microregion in Chester Parish, just north of Grijzestad. The Philip Spock winery (Brunant's oldest) is found here, as well as the third largest producer nationally, Round Tree Estates.
The Secret Lakes is a small yet very fertile region in Sint-Anders Parish. Its terrain gives the local wine a deeper flavor and is highly enjoyed island-wide. The largest winery in the region is the Blue Caves Vineyard.
The Lower Chester is a large winemaking region in the valley.
The Ambrosian Hills is a microregion in the lower Chester. This region is considered to be the best for winemaking, and the local wines are the best in the country. The famous Anselme and Château Pinsky wines are produced here, as is the Morels, fourth largest in Brunant.
Winemaking in the region dates back to the 1500s when several settlers planted Moscatel de Alejandria grapes from Portugal and Spain. These grapes were used to create the distinct Brunanter Moscatel, a sweet wine used for desserts. The earliest commercial wineries date to the early 1500s and the oldest existing one is Philip Spock, dating to 1587 and producing wine under the Grizespock label since 1620.
Winemaking is a very important part of the region's economy. Much of the wine is exported to places in North America, Lovia and other parts of Europe. This business also attracts tourism, to wine tasting and to the yearly Chester Valley Winefest.
In 2011, total wine production amounted to 524,000 bottles, or 43,679 cases.
