Establishment Jam Rock Blackberry Sour - 30 Litre Keg

Jam Rock is a highly sought-after seasonal release from Calgary’s The Establishment Brewing Company. This Blackberry Sour with Vanilla is designed to mimic the experience of a liquid berry cobbler or a fresh fruit preserve. Part of Establishment's commitment to "world-class beer without the pretension," Jam Rock has become a cult favorite for its vibrant color, bold fruit profile, and the expert balance between sharp acidity and smooth sweetness.

Beer Description

This fruited sour pours a stunning, opaque deep purple-to-burgundy color with a fleeting, pink-tinted foam head.

Aroma: It features an explosive nose of ripe, jammy blackberries. The fruitiness is complemented by a delicate, creamy scent of Madagascar vanilla bean and a bright, lactic tang that signals its sour profile.

Palate: On the tongue, it is medium-bodied and incredibly flavorful. It leads with an intense tartness from the blackberries, which is immediately softened by the silky, rounding influence of vanilla. The result is a profile that tastes like a tart berry pie filling, finishing with a refreshing, puckering acidity.

Profile: It typically carries an ABV of around 5.6% and negligible bitterness, as the structure of the beer is defined by its acidity rather than hop character.

Technical Notes: Brewed using a kettle-sour process to achieve a clean, consistent tartness. It is conditioned on massive amounts of real blackberry purée and infused with high-quality vanilla beans. The addition of lactose (milk sugar) is often used to provide a creamy mouthfeel and to balance the sharp acidity of the fruit.
