Netting Grapes
The mild (until now) summer has resulted in a slow ripening of the grapes. As soon as the first bunch started to turn from green to various shades of pink, red, purple and black out came our nets. Last year the nets were left off too long and the parrots quickly removed the bulk of the crop. The weather has surged to hot suddenly and the bunches all quickly commenced and completed the transition to red.
We use white bird netting because tests have shown they let through a touch more UV light. They also look spectacular in the vineyard contrasting against the green grass background.
The vineyard consists of only 150 vines, a mixture of Isabella, Chambourcin and a few Tannat. The Isabella are slowly being either replaced or grafted over to Chambourcin. The Chambourcin were chosen because their hybrid nature makes them more tolerant of the humid conditions and no spraying is required to fight mildew. It is possible to make good wine from Chambourcin but it does need to ripen well and to do this requires minimising the number of bunches per vine.
The harshness of our rocky outcrop results in vines which send out roots horizontally as that is the only place they can go. This makes them susceptible to suffering in dry conditions but every now and then we manage to make some wine from our own crop. Mainly it is just to have a vineyard of one’s own rather than a sensible agricultural pursuit.
The most recent investment involves re-trellising the rows. The original trellising was a Hodge podge affair established quickly without a lot of forethought. Now that we know we can keep the vines alive a new trellising system is in progress. Experience has shown that a taller trellis seems to produce a better result. Based on the investment in material and time each bottle costs in the hundreds of dollars. Well we don’t own yachts or racehorses.
Reading
This year has been the first time we have both used the festive season to relax and do as little as possible. The flurry of activity leading up to Christmas involved getting the place ship shape with mowing and weeding.
Part of the preparatory process was to stock up on a large number of library books both fiction and non-fiction. A real kaleidoscope of genres and authors to make sure that all moods were catered. A few library DVDs rounded out the stockpile.
What a wonderfully relaxing couple of weeks sitting around eating, drinking and reading. Occasionally pottering around to settle a meal or a little exercise to justify the next feast.
All this rest and recreation will come to an end soon enough and gardens will need weeding and planting, the lawns will need some attention as well as the long list of jobs that need doing will be unearthed.
Sparkling Wine
One of the pleasures we are enjoying with the hot weather is sipping on a glass or two of sparkling wine. The pleasure is doubled because this is our own sparkling Semillon. For whatever reason (and these experiments are always in the lap of the gods) this batch tastes splendid. It may be the hot weather, it may be that we are taking some time off or it may be just that it is good wine. There is only a very small amount of sulphur used barely 50 ppm. We only made 9 bottles of this sparkling with the rest bottled as is.
Looking at the vintage diary again after almost 12 months. The grapes were crushed and de-stemmed with the skins soaking for 12 hours and the temperature chilled to just below 11 degrees Celsius before pressing. Brix at 22 and pH at 3.24. The fermentation proceeded in glass under airlock until Brix had dropped from the original 22 to 8. The temperature was kept between 10 and 15 degrees Celsius. The lees were stirred each day except for the last day when the must was racked and French Oak added at 5 grams per litre. Bottling was left until the wine had completely cleared in August. Some years we have cold settled before bottling but this was unnecessary this time.
We cap our sparkling with a crown seal and don’t proceed to the stage of disgorging. When opening the bottle it’s only a matter of decanting the wine in the same manner as a homebrew beer, leaving the sediment at the bottom of the bottle.
Tomatoes
As with the grapes the tomatoes have also been slow to ripen. Although there are always plenty to eat it has been difficult to gather enough ripe fruit to bottle. Still because of the previous year’s bounty we don’t need to make all that many jars. As long as the tally reaches 50 or so by season’s end we should be covered. There is also a backlog of dried tomatoes which we can use as filler.
In terms of eating fresh tomatoes we have been very impressed with the smaller varieties such as Red Grape and Cherry. A very intense sweet flavour that enhances a salad. Unfortunately trying to collect several kilograms of these for pureeing is just too hard so the larger less tasty varieties such as Roma fit the requirement. Particularly tasty has been Black Russian, our first planting of this variety. It has good size, firmness and is delicious.
Some of the other larger varieties have failed to perform this year but that happens from time to time. Their turn will come. Now that January has arrived it won’t be much longer before the fruit fly takes over the larger fruit leaving us dependant on the smaller varieties for day to day eating.
Bottling the last of the 2010 Malbec
The last batch of Malbec was 32 litres. It had been pressed and stored in the demijohn on February 12 after the addition of 6 grams per litre of French Oak chips.
The grapes were picked and crushed on February 3. The pH was 3.67 and the Brix 22.2. A little Tartaric acid was added to adjust the acidity and BDX yeast used. About 10% of the stems were added to the must. As is recommended for this manufactures’ yeast a small quantity of yeast nutrient is added. We split the nutrient into three batches adding one at the beginning, one when a third of the fermentation is complete and the final quantity at the two thirds mark.
The day after crushing 5 litres was bled off to make some Rose and fermentation was apparent by the day after. When fermentation commenced the temperature was 19.9 degrees Celsius. By the following day the temperature was lowered to between 14 and 15 and until pressing the temperature kept between 12 and 15. This stretches out the fermentation period giving more skin contact.
On February 10 we pressed another batch of Malbec and added the skins to this batch. This increase in the skins to juice ration should make for an interesting effect. Because no preservative is added we pressed when the fermentation was two thirds complete and the still fermenting must put in glass under airlock.
We look forward to see how this develops with age.
