Core Range


Our Mackenzie William is named after the eldest grandson of Trevor and Marilyn Harch. Our Eden Valley Riesling is delicately hand-picked from our longstanding vines planted in the 1960s, 1980s, and from our cherished, deep rooted 1890s vines – believed to be some of the oldest in Australia. Each batch of fruit bestows its unique attributes, creating quintessential Eden Valley citrus and minerally characters which we are so well known for, and a complexity that ensures our dry style’s impressive length of finish.

A vintage with some beautiful warm nights has influenced the aromas of our 2019 Riesling, giving a perfume of fragrant florals and young lime leaves. Far reaching flavours travel by express, widely across the palate, with waves of soft citrus, pears and classic brown lime cordial meeting in the middle. As ever, variety and region form the finest partnership while creating our Riesling, finishing dry, with a structured natural acid mineral finish. This dry style Riesling, when cellared carefully, will mature gracefully for at least 10 to 12 years, if not longer.

2019 Vintage Summary:

The 2019 vintage overall produced very high quality, but lower/limited supply, with the Barossa region as a whole down between 50-80% on the prior year, and some vineyards not picking at all. This was due to very hot, dry conditions in January and February. 2019 will be the lowest-yielding Barossa harvest of the past decade. Brockenchack vineyard however was only down 20% due to great care and management in our vineyard. We believe this is attributed to several factors, including the addition of both nutrients and cow and chicken manures, added rotationally to the vines directly and via liquid fertilizer irrigation each year. Good soil moisture kept our vines healthy in the hot spells thanks to irrigating at the right times – in Spring before budding and again at flowering – coupled with our under vine mulching helping to retain this moisture for longer, thereby resulting in healthy crops throughout the rest of the growing season. The result for Brockenchack was an excellent quality, but slightly lower quantity vintage.
