A fairly strong, malt-accentuated, lagered artisanal farmhouse beer.
Three main variations are included in the style: the brown (brune), the blond (blonde), and the amber (ambrée). The darker versions will have more malt character, while the paler versions can have more hops (but still are malt-focused beers). A related style is Bière de Mars, which is brewed in March (Mars) for present use and will not age as well. Attenuation rates are in the 80-85% range. Some fuller-bodied examples exist, but these are somewhat rare.
