Rochefort Brewery (Brasserie de Rochefort) is a Belgian brewery which produces three beers designated as Trappist beers. The brewery is associated with the Rochefort Abbey, which originated in the thirteenth century; monks have been brewing beer at Rochefort since the sixteenth century, providing much of the income for the monastery.
- Rochefort 6 (red cap, brown beer, 7.5% ABV). Reddish colour, brewed only about once per year, representing approximately 1% of total beer production. This beer begins with a density of 16.5º Plato is 7.5% ABV. "Rochefort 6" is the oldest Rochefort Trappist beer and was brewed empirically until the end of the Second World War. Until 1958, this was the only Rochefort beer that was bottled in both 33 cc bottles and 75 cc bottles. It has a strong malt taste and is slightly bitter.
- Rochefort 8 (green cap, brown beer, 9.2% ABV). Yellowish-brown colour, with more fruits and a slight amount of Demi-sec. This variety constitutes the largest proportion of production. Dates from 1955. Originally this beer was only brewed for New Year’s Eve celebrations. "Rochefort 8" begins with a density of 20.8º Plato and reaches a final 9.2% ABV. Due to the overwhelming success of this beer, the monks decided around 1960 to brew it on a regular basis. Sometimes this beer is also referred to as the "Special".
- Rochefort 10 (blue cap, dark beer, 11.3% ABV). Reddish-brown colour, begins with a density of 24.5º Plato and ultimately reaches 11.3% ABV.
The beers are called Rochefort 6, 8, and 10, referring to their gravities in the obsolete (but quite practical) system of Belgian degrees, in which 6 corresponds to an original gravity of 1.060 (15 degrees P), 8 corresponds to 1.080 (20 degrees P), and 10 corresponds to 1.100 (25 degrees P).
