St Bernardus would have to be one of the most criminally under-rated breweries in Belgium I reckon. They are probably most well-known for the fact they used to produce the Westvleteren beers under licence (1946-1992), and people compare their ABT 12 to the Westy 12.
But they are an exceptionally good brewery in their own right, with each of the beers I’ve ever tried from them being an excellent example of the style.
The Pater 6 is a Belgian dubbel style, so think of beers like Westmalle Dubbel or Rochefort 6. The dubbel is a staple beer in most traditional Belgian beer portfolios, and while it may not be the trendiest, most talked about of beer styles, dubbels are very easy beers to suggest to drinkers of all levels and experience.
The beer pours a lovely brown colour with an aroma of sweet caramel malt, dark fruits and Belgian yeast. The dark malts and Belgian candi sugar offer an inviting sweetness up front. There is also dried dark fruits and a little spice on offer, with a good carbonation aiding a dryness to the finish.
