One vineyard, many expressions
Wednesday 1 February
Welcome to day one at the eighth International Cool Climate Symposium in Hobart, Tasmania.
My brain hurts after today’s seminars, which have focused on many technical issues relevant to vineyard managers and winemakers. I have to admit ‘applied geometrics’, and ‘spatial and temporal changes in fruit composition and juice in the vineyard’ had me pretty bamboozled.
Dr Richard Smart presented the results of a study into Pinot Noir at Tamar Valley winery, which was at times confusing, particularly when he started recommending a book about Antarctica that he’d just read, but we soon got back on track!
The main tenets of his seminar were that two bunches from the same vine can produce wines that are totally different in composition.
By vinifying each bunch separately the research found a wide range of different colours and tannin levels. It also revealed that exposure of bunches to UV light reduced botrytis infections and also increased colour and tannins.
Going as far as the berry level, shrivelled berries produced wine that was 40% higher in phenolics than its non-shrivelled equivalent and tannin increased 120% despite just a 10% increase in sugar levels. Weirdly, berry size had no impact on wine colour or phenolics, which goes against what I had always believed…
Smart concluded, “Bunch variability is the most important thing for Pinot Noir”.
So, it seems you can have one vineyard, one vine or even one bunch and the resulting wines are different beasts.
What does this mean for our notion of terroir and single vineyard wines when there is such enormous variability within those sites? I’m not sure my head hurts too much but it does raise some questions to contemplate.
In the meantime maybe I’ll go and read that Antarctica book. It might be a bit easier on the brain.
Wine: made in the vineyard or winery?
Tuesday 31 January
Most wine producers will tell you wine is made in the vineyard (alongside overdelivering on quality and other such wank phrases). But what if it isn’t?
Ok, so you can’t make a silk purse out of a sow’s ear and your fruit does need to be good for starters - but a tasting at Frogmore Creek in Tasmania’s Coal River Valley today put the influence of the winemaker back in the limelight.
Winemaker Nick Glaetzer, of the renowned Glaetzer family, says, “Terroir is important but the winemaker can also play a role in making a wine more exciting.”
His team have been experimenting in the winery to see what they can do with its Pinot Noir fruit.
And with most vineyards in Tasmania still lacking old vines, winemaking techniques seem to be crucial to create more interesting wines. “I thought that because we were not getting the complexity from old vines we had to be something about it,” adds Glaetzer.
This experimentation breaks the current mould of winemakers telling us that their wines are made in the vineyard with minimal intervention.
Glaetzer showed us nine wines from the 2007 vintage. The Pinot Noir grapes were picked at the same time from the same block but were fermented differently. Kicking off with a ‘control’ wine, the flight included everything from a 100% carboic maceration ferment to a co-ferment with Chardonnay. Interestingly the Chardonnay addition seemed to make the wine more supple and velvety with a pronounced nutty character.
Curiously, there was an Amarone style wine that had been produced from riper grapes. Compared to the control wine it produced a richer style of wine, fuller in body with heaps of black cherry and raisin-like flavours not seen in the control wine. The tannins were more abundant too. It shared the fleshy mid palate of the control wine but little else. If I hadn’t been told it was the same wine, I would never have guessed.
The ninth wine was the final blend, which includes 25% of the Amarone style wine with the other components each representing 5-8%.
This process is followed every year with components of the 2011 Pinot blend including a splash of a Pinot Gris-Pinot Noir blend “which looks a bit baggy,” admits Nick, and a Gewurztraminer-Pinot Noir batch, displaying a weird combination of Pinot red fruit flavours alongside orange and exotic spice.
The tasting messed with my brain, combining some techniques and blends that my palate had never experienced. It is also interesting to see the many expressions of one terroir, and that the winemaker’s decisions from minimalist to interventionist do impact on that expression.
Grand plans for Gibbston Valley
Friday 27 January
Queenstown has the fastest growing airport in Australasia and members of the Central Otago wine industry are recognising the opportunities this provides.
Gibbston Valley wines, in particular, has grand plans for 2013. It already welcomes between 80-100,000 visitors through its doors each year, and now it has applied for 50 apartment style rooms to be built at Gibbston Valley. Just 2km down the road from the winery, its CEO, Greg Hunt, has designs for a spa, 18-hole links style golf course alongside the Kawarau river plus a vintners market.
Greg Hunt, Gibbston’s CEO, says, “We are hoping to start construction at the beginning of 2013.”
He reveals they have already received the consent for a resort but the economic crash put paid to their initial plans but next year is the year to resurrect this grand design.
He would not reveal, however, how much this would cost!
