from the brewery - pretty clearreddish-brown beer with no foam; aroma of sour cherries and pulms; some earthy notes hidden below; low carbonation, tasty and assertive, a fair sourness, dry aftertaste of cherries, berries and prunes with lingering notes of wood and vinegar - superb ! anstei (2358) - Zurich, SWITZERLAND - MAY 28, 2017
Bottle, courtesy of DerA. Pours hazy light brown. Aroma is brett, hay, farm, lots of malt. Body is light, sour, acidic, and rather tart. A bit chalky, rather malty for Blackwell. Palate is dry, with a fruitiness similar to a sour red. Good. markoijelena (3143) - Belgrade / Amsterdam, SERBIA - MAR 15, 2017

Clear medium amber color with a small, fizzy, virtually none lacing, fully diminishing, off-white head. Aroma is moderate malty, caramel, tart, wood, vinegar. Flavor is moderate sweet, acidic and acetic with a long duration, vinegar, tart, caramel. Body is medium, texture is watery, carbonation is flat. 
a sour alt? whatever it is it is my first introduction to Swiss sours and if that country keeps turning out beers like this I would be very happy.
Tap at In De Wildeman kermis (13882) - The Hague / Amsterdam, NETHERLANDS - FEB 2, 2017
Tap at In De Wildeman. Near clear amber brown with a small short lived cream head. Aroma of tart red berries, mineral notes, vinegar, malt, light leather and caramel. Flavour is light moderate sweet and moderate sour. Medium bodied with soft carbonation. Not sure why this is listed as an altbier, comes across closer to a Flemish brown. derA (91) - Zurich, SWITZERLAND - NOV 6, 2016
enjoyed on brewery premise during a tasting: copper amber color, no head whatsoever, nose is an amazing mix of malt and prune and apricots, maybe a little caramel? aroma is acidity in perfect harmony with caramel and fruit. However, finish is slightly boring with nice lingering acidity but not certainly not overwhelming. excellent and unique to have such harmony of clean malt and acidity. adamnowek (2832) - Brussels, BELGIUM - JUN 28, 2016
Dirty brass colour and looks thick as mud. Aroma is vinegar and lemon juice. Taste is pretty sour at the start with a citric, vinegary finish.
