Sadly the Trappistes Rochefort with the red cap is the last of the famous triumvirate to pass my eager lips. Just over a hundred beers in and I need to conclude my notes on this fantastic Trappist brewery. To be honest there isn’t a lot else to say that I haven’t already covered in reviewing the Trappistes Rochefort 10 (#13) and Trappistes Rochefort 8 (#31), apart from the fact that interestingly these range of beers have only recently acquired labels. Previously images were screened directly onto the bottle and thus if you find one of these on your travels then hang on to it, or pass it my way!
What first started to baffle me though was why the Trappistes Rochefort beers are called 6, 8 and 10. Clearly this is not to do with their ABV as the Trappistes Rochefort 6 weighs in at 7.5% however it is to do with the overall gravity of the beer. The difference is that various scales have been used over time to measure essentially the same thing. Original gravity in a nutshell is a reading which is an estimate of the amount of sugar which will be turned into ethanol by the yeast, and is usually calculated using a table of figures. The reading will express the sugar content in units of grams of sugar per 100 grams of wort, and it is usually expressed as “degrees Plato” (abbreviated °P). As mentioned, different scales have been used in various places, and Rochefort in the good old days measured the gravity of their beers through the obsolete Belgian scale.
In this instance the 10 corresponds to 1.100 (25 °P), the 8 corresponds to 1.080 (20 °P) and the 6 corresponds to 1.060 (15 °P). This is the ‘original gravity’ (OG) as it is a prediction of the potential alcohol once the yeast has worked its magic on the sugar. Specific Gravity (SG) is a term often used, and is slightly simpler in that it corresponds to the relative density of a liquid, relative to that of water at a certain temperature. This is the gravity measured with a hydrometer. Brewers are able to compare the OG and the SG to monitor the progression of the fermentation. Essentially once the SG stops declining the fermentation has been completed. Happy Days !
The Trappistes Rochefort 6 essentially started off as the Pater beer (#2) for the monks, but it’s far better and stronger than a typical table beer. At 7.5% it lacks the killer strength of its older brothers but it is still a fine beer. It’s the hardest of the three to pick up but well worth it if you fancy a few without a headache the next morning. Its cleaner and thinner than the others, but the famous datey taste still permeates every mouthful and it remains just that bit more subtle. It’s readily available in the villages near Rochefort, although there is no brewery tap – it’s the only Trappist brewery without one. The Relais de St. Remy about 2km out of town is your best place to find it.
