Question: Where was a Belgian variety of hop cultivated, it is used for a type of beer brewed in the Pajottenland region of Belgium southwest of Brussels and in Brussels itself at the Cantillon Brewery?
Context: The Pajottenland (in English occasionally Payottenland) is a distinct region within the Flemish Brabant province of Belgium.  The region is located west-southwest of Brussels.  The Pajottenland is predominantly farmland, with occasional gently rolling hills, and lies mostly between the rivers Dender and Zenne / Senne.  The area has historically provided food and drink for the citizens of Brussels, especially Lambic beers, which are only produced here and in the Zenne valley where Brussels is.

Brussels lace is not to be confused with Brussels point, which is a type of needle lace, though is sometimes also called "Brussels lace". Viru is a 5.0% ABV pilsner-style beer brewed in Estonia.

Lambic is a type of beer brewed in the Pajottenland region of Belgium southwest of Brussels and in Brussels itself at the Cantillon Brewery.  Lambic beers include gueuze and kriek lambic.  Lambic differs from most other beers in that it is fermented through exposure to wild yeasts and bacteria native to the Zenne valley, as opposed to exposure to carefully cultivated strains of brewer's yeast.  This process gives the beer its distinctive flavour: dry, vinous, and cidery, usually with a sour aftertaste.

Coigneau is a Belgian variety of hop which was massively cultivated in the Flemish Aalst-Asse area near Brussels in the nineteenth and first half of the twentieth century.
