By all calculations, the land was once part of the Beetham Estate, and growing international quality wine as early as the 1880s, according to Derek Hagar, who with his father Derek Hagar, senior, runs the family owned business.
The Masterton vineyard owned by the Beetham family in the 1880s was scrapped when the town went 'dry' after World War I.
It lay between the Beetham homestead, now historic Lansdowne House, and the Ruamahanga River, which is where the Hagars put down vines in the early 2000s, on Masterton's Gordon Street.
The discovery of an early bell-shaped pump in the soil confirmed Mr Hagar senior's suspicions that his new vineyard was on the same site as the old, and a survey showed five different natural springs on the land.
For the first two or three years, the vines planted by the Hagars did it hard, with many dying and having to be replanted.
"A lot of stones as big as footballs" prevented the roots from pushing down into the soil for water, and the vines that did survive did after a struggle - but that was all for the best, Mr Hagar, Junior, believes.
"We believe that vines which are stressed when they are growing up produce better fruit," he said.
The commitment to producing quality wine has led to steps such as pruning off 75 per cent of the grapes and to what the Hagars believe is the real key - patience.
The vineyard has also managed to harvest the difficult-to-grow Syrah for three years running, and believe they are the only Wairarapa vineyard to do so.
The vineyard's pinot noir, syrah and pinot gris wines are aged for two to three years in the bottle, and with no additions to the fruit - just the natural sugars of the grape.
"Whatever God sends us is what goes in the bottle," Mr Hagar, junior, said.
Lansdowne Vineyard's successes at the IWSC so far include silver, outstanding silver and bronze.
This year after even more bottle-ageing, Mr Hagar, junior, said, "our hopes are high" for even better results.
Lansdowne Vineyard wines are selling at a Michelin-starred restaurant in London, at a wine bar in Wellington for $79 for pinot noir or $175 a bottle for syrah, or from the vineyard itself.
