| Hiking through vines in the Asti Region of Northern Italy |
This is the first of probably many posts as we embark on our home vineyard journey.
Who, at some point, has not dreamed of the idea of growing their own grapes and making wine? The idea of looking down on the green vines from your summer deck, with a glass of wine in hand, thinking of the harvest. Or tending to the bare vines in the middle of winter, preparing for the next years crop?
To begin I did a lot of reading. Probably the best document I found is this one, published in all places, Queensland! Not really known for their wine, but the practices of growing grapes and making wine are quite standardised. The document is 20 years old, but the information it contains has agreed with every conversation I have had with local wine growers.
The other fantastic source of information has been from the local winemakers: Don at Welshman's Reef, Bruce at Chalmers and the kind people at Harcourt Valley Vineyard.
Next come the key questions:
- What varietal and clone to plant?
- What rootstock to pair it with?
- How many vines to order?
Firstly, we needed to determine what we want to grow and how many vines, so that we could place an order with a suitable grower this year before the end of June, so that our vines could be grafted and grown ready for planting in Spring 2019 (yes, 2019!).
The first question was one variety or two? The answer - One. Because you can make two wines from the one batch of juice. For example, a red and a rose. This gives some flexibility to the process depending on yearly yield and also simplifies the harvesting and fermenting processes.
There are so many varietals as well as root stocks, but we have chosen Sangiovese clone Matura 7 (Mat 7). This is because Sangiovese is less common in central Victoria (Shiraz being dominant) but grows well, particularly in the Heathcote area. Secondly, it is a forgiving grape, like Shiraz, but unlike Tempranillo which can be low in acidity. The Mat 7 clone was suggested as it simply makes great wine and has vibrant, dark fruit. This is a clone that is being grown both locally and in the King Valley region.
Rootstock is another key selection criteria. Our objective is to grow un-irrigated, once established, therefore a recommended rootstock is Richter 110. This sends down deep roots and therefore tolerates drier conditions. It is also of medium to high vigour, meaning that the yield should be good despite the low water use.
To determine how many vines to plant we sat down with Ron and Julia from Welshman's Reef Winery and did some back-of-the-envelope calculations:
Assuming we get 3kg fruit per vine...
200 vines would give 600kg fruit...
Assuming 60% juice yield, this gives 360 litres juice...
Which can fit in either a Barrique (225 litres) or a Barrel (360 litres), as we are aiming for barrel aged wine which makes a more professional wine than oak chips.
Therefore if we have a good year we can use most of the juice to make a red wine and the remainder
to make a rose.
So, we have now ordered 200 Sangiovese Mat 7 + R110 clones from Chalmers Nursery based in Mildura, which will be picked up by us in October 2019.
In the next post we will cover vineyard layout and preparation.
