How about Chimay? Brewed by Belgian Trappist monks, IIRC, and needs to be treated with the utmost respect! One is about 10%abv, another is around 14%abv – falling over water indeed!
Yes, Trappist brewers https://en.wikipedia.org/wiki/Chimay_Brewery
The strongest is 10%
Chimay Red, 7% ABV. In the 75 cl bottle, it is known as Première. It is a dark brown colour dubbel and has a sweet, fruity aroma.
Chimay Blue, 9% ABV darker ale. In the 75 cl bottle, it is known as Grande Réserve. This copper-brown beer has a light creamy head and a slightly bitter taste. Considered to be the “classic” Chimay ale, it exhibits a considerable depth of fruity, peppery character.
Chimay Triple, 8% ABV golden tripel. In the 75 cl bottle, it is known as Cinq Cents. This crisp beer bears a light orange colour, and is the most hopped and driest of the three.
Chimay 150, 10% ABV blonde ale. Originally brewed as a special, 150th anniversary ale, now in regular production. Noted for its spicy, smoky character.
Chimay Dorée (Golden), 4.8% ABV ale, brewed from very similar ingredients as the Red, but more pale and spiced differently. It is a patersbier, intended only to be drunk at the Abbey. Since 2007 it was available at the nearby inn Auberge de Poteaupré, which is associated with the abbey.[9] The monks themselves drink this variety rather than the stronger three. Prior to 2015, it was unusual for bottles of the Chimay Dorée to be available outside the Abbey or local inn. However, from 2013, a limited quantity of this beer was sold on draught in the United Kingdom, at 19 Fuller’s pubs[10] and in Italy, where only 50 pubs sell this variety of beer, as well as in 330 ml bottles in some export markets.[11][12] In the Christmas season of 2016, Chimay made available a gift set with all four varieties and two chalices,[9] and since has been available in limited quantities in the USA.
