Gemstone Riesling

Gemstone - Our Crown Jewel. A unique single vineyard Riesling with a quarter of the blend fermented & matured in granite tanks.


Enticing and textural with notes of luscious citrus blossom and white florals. A beautiful flow and balance with subtle sweetness and hints of smokiness.

All the fruit comes exclusively from the Giesen-owned Eden Valley Vineyard in the lower Waihopai Valley. The vines have an average age of more than 20 years.

A portion of the blend is fermented and matured in granite tanks. It’s the use of granite which makes Gemstone special.

Granite tanks are made from one giant slab of plutonic rock and the French have been fermenting in them for centuries. Granite acts a little like oak barrels, it lets air in and the ever so slightly ‘sweats’, this slight evaporation adds concentration to the wine. This ensures the wine portion matured in granite is clean, bright and full of flavour.

A unique Gemstone of a wine.

Winemaking

Fruit is hand harvested before being pressed as whole bunches.

The free run juice was fermented in a combination of granite tanks, used French oak barrels and stainless. 

After fermentation the wine is matured on light lees for five months.

The use of granite adds another dimension to the wine, creating an intense, pure Riesling.

Reviews

"2017 Vintage: It is delightfully charming on the nose showing lime sorbet, red apple and white floral characters with a hint of savoury complexity. The palate is concentrated and linear, displaying delicate fruit intensity and fine texture, fabulously enhanced by elegant sweetness and perfectly pitched acidity, leading to a superbly long juicy finish. At its best: 2018 to 2027."

Sam Kim - Wine Orbit

"2017 Vintage: Very fragrant and quite complex with aromas of flowers, apples, citrus fruits and spice. On the palate – off-dry, but with a focused acidity the wine finishes almost dry. Flavours of lemon and ginger tea, apple and honeysuckle. A lovely example with concentration and length. Drink now and through 2028."

Cameron Douglas - The Shout

"2017 Vintage: This new limited release label for Giesen offers a medium riesling with precise, taut acidity creating lively tension with some residual sweetness. An appealing wine in a great aperitif style and with the potential to develop well in bottle."

Bob Campbell - NZ Master of Wine

"2017 Vintage: This thought-provoking wine was handled in stainless-steel tanks, oak barrels and large granite tanks. Full of personality, it is light-bodied (10% alc/vol), with incisive lemon/ lime flavours, seductive balance of sweetness and acidity and a lasting finish."

Michael Cooper - NZ Wine Writer

"2017 Vintage: A gorgeously seductive, sweetish wine, a portion of this wine was fermented and matured in granite tanks, which may be responsible for the clean and incisive minerality and excellent concentration."
