Boon jonge lambiek is a lambiek that generally has been aged for less than 1 year and is served at the brewery, at festivals, and at bars around Belgium and elsewhere. The exact time when a beer switches from oude to jonge is based on the fermentation progress and is at the brewer's or blender's discretion. Jonge lambic still and maintains many of the fresh sugars that enable an active fermentation. It is primarily used in blends with 2 and 3 year old oude lambiek to create a geuze blend.
Boon generally does not provide jonge lambiek directly to consumers or blenders.
