Before launching their own label, the Willson family grew grapes which went into Australia's most notable wines. Today, Bremerton are in a unique position to keep all parcels of wine separate from the time of picking through to fermentation and maturation. The most elite quality Shiraz grapes from low yielding vines are fermented in open vats, followed by two years maturation in completely new, extra fine grain American oak barriques. Following a spell of racking, each parcel is assessed and the most outstanding barrels are earmarked for inclusion. Those parcels worthiest of the Old Adam moniker are treated to another year in bottle prior to release, further integrating the oak, tannin and fruit.
