3 Fonteinen Zenne y Frontera (Batch 1): This natural millésime beer is a blend of young lambics that have been aged for another 12 months in 40 year old Oloroso and PX sherry casks. Thanks to the long maturation, the geuze-like notes of our authentic 3 Fonteinen lambik are well accentuated by the typical, fine Oloroso and Pedro Ximénez characteristics. By gently decanting the Zenne y Frontera, the aroma of this unique lambik will evolve from vividly tangy to a complex nutty and fully fruity bouquet. StrengeWinter 19-20: Strenge Winter is a blend of 3 fonteinen full malt beers and candi sugar. Spontaneously fermented. Matured in oak barrels. Extended bottle ageing. Unfiltered. Unpasteurised.
