330 ml long neck & capped bottle. Poured in a ( Belgian ) Trappisten Chalice an unfiltered, murky, almost opaque and ruby dark brown coloured Trappisten Dubbel with a one finger fine, dense, creamy and beige foamy head that had a very long retention and tons of micro bubbles.Soft carbonation. Great lacing.The aroma is yeast, malty, caramel, brown bread and dried fruits, raisins, prunes.The flavour is sweety and roasted malts, caramel, brown bread, herbal notes, dark fruits, prunes, figs, spicy, cloves, nutmeg and woody tones.The mouthfeel is creamy, quite fulled, sparkling and silky. The texture is oily.This medium to full boddied Trappisten Dubbel has a long malty and fruity finish so a pleasant soft warming continuation.This collaboration beer between three Trappist Breweries, Tre Fontane / Rochefort / Westmalle is brewed in Roma, It' s rich flavoured and nicely balanced, an Italian touch is not really to detect, Sinergia '21 is a classical " Belgian " Trappisten Dubbel. I enjoyed it.
