Season 2022-2023, Assemblage #105. Bottled on 03/11/2023. " collaboration with Brasserie De La Senne. ‘Terf’ first saw the light of day in July 2020. This local wheat beer was brewed by Brussels-based Brasserie de la Senne using old wheat varieties from the cereal collective of Brouwerij 3 Fonteinen from Beersel in Brabant. Part of the brew was immediately drawn onto small bottles and sold out immediately. Another part of the brew matured further for three years in oak lambic barrels. In November 2023, this ‘matured’ Terf was lit with young 3 Fountains lambic, in a 55/45 ratio. This Wild Terf is the fruit of collaboration between brewers and farmer(s) around Pajot landraces and with a fair income for the farmer. Above all, it is an ode to the historical agricultural link between the Brabant countryside and Brussels."

"Mixed Fermentation Golden Sour with Scottish Blackberries. Blended from four batches of golden sour beers all primary fermented with different Brettanomyces strains and brewed with locally grown malted barley, wheat and oats. This blend has an average age of four months and provides bright tropical, stone fruit and red berry aromatics. We conditioned this blended beer on 220g/l of locally grown Scottish blackberries (aka brambles). The resulting beer has an intense red/purple hue, and aromas of a tropical berry fruit medley. We get sweet/sour tangy, hedgerow berries, guava, jammy raspberries and some light tannin from the berry skins."

"This Flanders Red style beer was blended from 80% provision strength ‘young’ stock beer aged 4 months, along with 20% of our most ancient ‘mature’ stock beer which has been aged in whisky casks for nearly three years. The combination of very old and young beers has produced a complex sweet and sour flavour profile with a subtle oak character. This blend was conditioned on whole British grown apricots and plums (approx. 200g/l total) for six weeks. Whilst the apricots were destoned by hand, the plums were left whole to breakdown slowly during refermentation. The result is a complex sweet/sour/savoury blend with notes of apricot, oaky funk, tart plums, dates and toffee apples."
