Production Details Officially identified as a non-vintage BSA release with a 2017 base. Malolactic fermentation was partial. Aging exceeded four years, but the source gives no exact day count or explicit lees-aging statement. Dizygote 2 was held under a capsule for the tirage-aging period; its paired Dizygotes 1 counterpart was held under cork. The producer states that the two shared the same years, varieties, vinification, dosage, and aging time, with the tirage closure as the distinguishing production variable.
