A delectable Marlborough Chardonnay that represents the very best of each vintage and over delivers on quality. A favourite among a few of the team here at Giesen.

We use fruit from our world renowned Clayvin vineyard as well as from premium vineyards throughout the Wairau Valley in Marlborough.

Early in the growing season we determine which grower vineyards will have the best Chardonnay fruit best suited for The Brothers Chardonnay and we work with them in managing those blocks throughout the season.

We pick early to maintain natural acidity that Marlborough is famous for.

Striking aromas of hazelnut, hot rock, grilled stone fruit and brioche, combine with a multi-layered, succulent and focused palate to create a wine with great depth and character.

Just as the three Giesen brothers journey bought them to New Zealand we travel to great lengths to find the best of every vintage. We strive to ensure The Brothers wines are rich and rewarding while retaining elegance and purity.


Marlborough - Clayvin Vineyard and Wairau Valley


Warmer ferment in 300L French barrique barrels (20-25% new) which adds complexity & texture to the wine.

A portion of the wine is wild yeast fermented to add a bit of interest. The balance is fermented using classic Chardonnay yeasts.

A portion goes through malolactic fermentation to balance the overall fermentation, this adds textural elements, complex aromas and balances the acidity.

Matured in predominately French oak hogsheads and puncheons and 1000L German oak Fuder barrels for 10 months. Oak age is a mix between one, two and three year old with the balance older. This selection is to ensure the wine has subtle oak character which allows the fruit to shine.

Dan Murphy's Wine Panel

"2017 Vintage: A bouquet showing complexity, ripeness of fruit and enticement from oak, lees and a flinty mineral-like layer from clever winemaking. Dry on the palate with a great texture once again from attention to detail using lees and oak, fluffy solids and ripe fruit. Flavours of fuzzy white peach, apple and lemon. Well placed use of oak, vibrant texture, freshness and a lengthy finish equal a well made and enticing example. Drink now and through 2024. April 2018"


Cameron Douglas Master Sommelier

"2016 Vintage: Inviting and charming bouquet with Chardonnay and winemaking scents of ripe red apple and citrus, heirloom orchard peach and a hint of quince. Generous, lush, fruity and youthful on the palate with sweet acidity, mild oak flavours with baking spice moments. Some floral and stony mineral tones; balanced and well made. Best drinking from now and through 2024."


Cameron Douglas Master Sommelier

"2015 Vintage: Giesen The Brothers Marlborough Chardonnay 2015 – An engaging bouquet of spice and ripe tree and stone fruits, aromas of baking spice and mild toasty wood tones with suggestions of fresh and baked apple, white and yellow peach. On the palate – medium+ body with a firm youthful texture from the bright acidity and newer wood layer, contrasting light creamy layer and distinctive tree and stone fruit flavours. Balanced and well made, drink today and through 2021."


Cameron Douglas Master Sommelier

"2014 Vintage: Fresh, vibrant, juicy fruit aromas and a mix of new and seasoned oak suggestions; vanilla and peach, apple tart and custard. Juicy, fresh and lively on the palate too with flavours of stone and tree fruit, gentle oak spice, medium+ acidity and lengthy mildly creamy finish. Great balance and length. Drink now and through 2022. "


Cameron Douglas Master Sommelier

"2014 Vintage: Pure and fragrant with good oak and fruit. It had toast, pure palate and a good richness, and was complex and sweet. Charry, with burnt butter and lemon zest. It had lovely, attractive fruit and good oak."


"2014 Vintage: It was love at first taste for the entire panel with this wine. “Understated, but so elegant and sophisticated,” said Jane Boyle. Apricot, citrus, mealy and hazelnut flavours are tethered to a persistent flinty seam. It is a joyous mouthful, finishing lengthy and dry. Another great seafood wine; serve with fish poached in chilli-infused coconut cream"

Cuisine Magazine

"2014 Vintage: Vividly floral, with a punch of honeysuckle to the peach and citrus flavors. Ripe, spicy and juicy on the finish. Drink now. 5,000 cases made."

Wine Spectator - MaryAnn Worobiec

"The 2014 vintage is a fragrant, generous wine. Grown in the Wairau Valley and the Southern Valleys, it was fermented with indigenous yeasts in French and German oak fuders (big, 1000-litre barrels). The bouquet is complex, with ripe-fruit aromas and hints of toasty oak; the flavours are rich, peachy and slightly buttery, with excellent depth and harmony. Drink now or cellar."
