Diane Madeline has found her oenological paramour. Kevin John is named after the estate patriarch and shares provenance with the most stately Margaret River Chardonnay. Grapes are picked at ideal physiological ripeness, after achieving healthy profiles of natural sugars. Acid levels in the fruit grown by Cullen are remarkable, with low pH and fine balance, making any additions for adjustment unnecessary. Chardonnay is harvested around the full moon to a cycle in accordance with the best biodynamic practices. Grapes are whole bunch pressed and spontaneously fermented in French oak barriques, two thirds of which are new, followed by partial malolactic and five months maturation.
