The Delta Wine Company Ltd

Marlborough’s Delta began with Southern Valleys Pinot Noir and now follows site character from Dillon’s Point Sauvignon Blanc to Hawke’s Bay Merlot.

The producer

Founded in 2000 as a specialist Pinot Noir project, Delta planted Dijon clones in Marlborough’s Southern Valleys, where elevated clay slopes, warm days and cool nights shape reds with bright fruit, acidity and fine tannin. Hatters Hill Pinot Noir 2021 brings black raspberry, crushed cherry and plum into earth, gravel, clove and smoke, finishing dry and persistent.

The range widens by place rather than by formula. Dillon’s Point Sauvignon Blanc combines grapefruit, lemon zest, tropical fruit and a saline finish from free-draining Lower Wairau soils, while Gimblett Gravels Merlot brings plum, boysenberry and a broader dark-fruit body. Delta wines have been made at Riverlands Estate since the 2015 vintage; Heather Stewart has led their hand-crafting since 2017.

Notable facts

The story

The Farm That Became Delta

Before it became Delta’s founding Pinot Noir vineyard, the original Delta Farm had already had several working lives. Constantine Dillon established the land in 1846. It later operated as a dairy farm and then a sheep farm, while the elevation of its hills made part of it useful as an airstrip. In 2000, the property was bought for the new wine venture and planted as its flagship Pinot Noir site. Detailed local topographic maps showed the vineyard’s outline resembling a capital Greek letter delta. That shape supplied the name for the estate and the label.

At A Glance

The Producer

The Delta Wine Company Ltd started in 2000, when three wine-industry veterans set out to make specialist Marlborough Pinot Noir. Their original Southern Valleys vineyard was planted with Dijon Pinot Noir clones, a choice that put a red grape at the centre of a region widely associated with white wine. Sauvignon Blanc, Chardonnay and Pinot Gris followed, while Merlot later brought Hawke’s Bay into the range. Delta’s stated aim is to let vineyard character lead, so the useful question on each label is not simply grape variety but where that grape was grown.

Place

Marlborough supplies Delta’s founding Pinot Noir and its Sauvignon Blanc and Chardonnay. The Southern Valleys are the Pinot Noir home: elevation, sunshine, warm days, cool nights and ventilation slow the rush toward ripeness, helping red fruit keep an acid line and tannin shape. Dillon’s Point, in the Lower Wairau, supplies Sauvignon Blanc from a separate Marlborough setting. Its slightly cooler summer nights and nearby sea influence suit a white with citrus energy and a saline edge.

Merlot changes the geographic frame. Delta’s 2022 Merlot comes from Gimblett Gravels in Hawke’s Bay, where warmer conditions support fuller berry ripeness. The result is a darker, broader red than the Southern Valleys Pinot Noir: plum and boysenberry rather than crushed cherry, with fine tannin rather than Pinot’s more linear grip.

Soil And Site

The Southern Valleys Pinot Noir vineyard combines clay soils with an elevated position. Clay can retain water while the slope’s exposure and moving air help moderate the growing season; together, those conditions support fruit depth without abandoning freshness. In Hatters Hill Pinot Noir, the physical outcome is black raspberry and plum wrapped around earth, gravel and firm but fine tannin.

Dillon’s Point Sauvignon Blanc grows on deep, mineral-rich ground shaped by ancient riverbed sand. The free-draining soils and cooler nights help preserve acidity as flavours develop, which fits the wine’s grapefruit, lemon-zest and sea-salt profile. In Hawke’s Bay, gravel, stones and sandy alluvial soils absorb warmth and aid drainage. Small, concentrated Merlot berries follow, bringing dark fruit and tannin to the finished wine.

Story

Delta’s history joins long Marlborough growing experience to a later Pinot Noir venture. Founding partner Neal Ibbotson and his wife Judy first planted vines in Marlborough in 1978, among the region’s early private grape growers. They built a winery at Riverlands Estate in 2005; from the 2015 vintage, Delta wines have been made there. Heather Stewart joined the Delta team that same year and took responsibility for hand-crafting the wines in 2017. The estate’s original Pinot Noir focus has therefore widened through a working winery and a larger vineyard network, while the Southern Valleys red remains the starting point.

Vineyards And Cellar

Delta monitors its Dillon’s Point Sauvignon Blanc until flavour, acidity and physiological ripeness are in balance. That harvest decision matters in a dry Marlborough white: picking too early can leave fruit thin, while waiting for flavour development can bring weight alongside the citrus. The 2021 single-vineyard wine shows both grapefruit and tropical fruit, with enough palate volume to carry its saline note.

For the Hawke’s Bay Merlot, selected yeast starts fermentation and the cap is hand-plunged up to eight times a day at its peak. That contact draws colour, fruit and tannin from the skins. Eight months in tanks and seasoned French oak follows before blending and bottling, so the wine’s plum and boysenberry remain in front while oak contributes texture rather than a dominant sweet-wood flavour.

Wines

Pinot Noir is the founding thread, with Hatters Hill providing the most detailed view of the house’s Southern Valleys work. The 2021 carries black raspberry, crushed cherry and plum, then earth, gravel, clove and smoke. Fine, abundant tannin and bright acidity make it a red built for a meal or time in bottle, with a stated window from 2024 to 2029 and beyond.

The Marlborough whites take different forms. Delta Estate Sauvignon Blanc from Dillon’s Point is a single-vineyard wine with citrus, tropical fruit and saline character. Hatters Hill Chardonnay 2021 moves toward white orchard fruit, apple, citrus and flint, with more mid-palate weight, acidity and fine tannin. Pinot Gris is part of Delta’s later expansion, while Rosé, Méthode Traditionelle and Pinot Blanc appear in the current collection.

Merlot sits apart as the Hawke’s Bay red. Delta Merlot 2022 uses Gimblett Gravels fruit and a longer skin-contact regimen to build dark-fruit body and fine tannin. It is not a substitute for Pinot Noir; it is the range’s warmer-climate counterweight.

In The Glass

Start with Hatters Hill Pinot Noir 2021: black raspberry and crushed cherry arrive with plum, then the nose turns toward earth, gravel, clove and smoke. The palate has bright acidity running through its fruit, while plentiful fine tannin adds dry grip and extends the finish. Its structure comes from a Pinot Noir site selected for its Southern Valleys conditions, not from a soft, sweet-fruited red style.

Delta Estate Sauvignon Blanc 2021 opens more sharply, with grapefruit and lemon zest before tropical fruit. The palate is weighty rather than merely brisk, and the hint of sea salt on the finish links the wine’s flavour to Dillon’s Point. Hatters Hill Chardonnay 2021 brings apple, citrus, orchard fruit and flint, then a fuller texture held by acidity and fine tannin. The Hawke’s Bay Merlot closes the sequence with rich plum and boysenberry, a darker body and smooth, fine tannin.

A Bottle To Understand It

Hatters Hill Pinot Noir 2021 is the first bottle to seek out. It joins Delta’s founding grape, Southern Valleys site and Dijon-clone planting in one wine, while showing why the project started with Pinot Noir rather than treating it as an add-on. Expect black raspberry, cherry and plum with earth, gravel, clove and smoke; bright acidity keeps the fruit lifted, and fine, abundant tannin leaves a dry, persistent finish. It has the structure for food and further bottle age, with a stated drinking window from 2024 through 2029 and beyond.

Anecdote

Before it became Delta’s founding Pinot Noir vineyard, the original Delta Farm had already served several purposes. Constantine Dillon established the land in 1846. It later became a dairy farm and then a sheep farm; the elevation of its hills also made it useful as an airstrip. In 2000, the property was purchased for the new wine venture and planted as the flagship Pinot Noir site. On detailed local topographic maps, the vineyard’s shape resembled the capital Greek letter delta. The map supplied the name that went onto the bottles.

Final Word

Delta is most clearly read through its sites: Southern Valleys clay and elevation for Pinot Noir with acid and tannin, Dillon’s Point riverbed soils for citrus-and-salt Sauvignon Blanc, and Hawke’s Bay gravel for darker Merlot. Start with the Hatters Hill Pinot Noir, then let the other bottles show how far the same site-led approach can travel.
