Peter Dry’s varietal egalitarianism
Sunday 12 February
Have you heard of Erbaluce? Or Manzoni Bianco? No? Nor me.
But Peter Dry, a viticulture expert at the AWRI, suggested that these two varieties should be considered by cool climate producers, instead of the usual suspects. Indeed international varieties have gained a rather superior status, and he is championing ‘varietal egalitarianism’. Let’s face it there are thousands of varieties out there and we are rather limiting consumers’ choices.
Dr Richard Smart added, “It’s rather insulting to consumers to limit varieties to half a dozen varieties.”
So, why should we be considering the likes of Erbaluce and other so-called alternative varieties?
“These varieties may be better suited to climatic conditions including drought tolerance,” said Dry. “There are cool climate areas with low growing season rainfall and high aridity.
“During times of drought our cool climate areas have sufered because they rely on water stored in dams and the dams are empty.”
As well as it being more suitable to increasing temperatures and lower rainfall, people might actually prefer to drink something other than Sauvignon Blanc and Chardonnay. “They may provide a greater range of flavours suited to the Asian palate. According to a CSIRO study, alternative varieties including Lagrein and Fiano may be better suited and may offer a competitive advantage.” said Dry
So, what is Erbaluce? An Italian white variety, that reaches maturity relatively early, is tolerant of botrytis, has good acidity and elegance. Manzoni Bianco, another Italian grape provides “good wine quality with structure and floral characters,” he added.
Ladybirds in our wine
Wednesday 8 February
Is that rancid peanut butter in my wine?
No, it’s ladybird taint.
But ladybirds are so cute. How can they taste so bad?
These cheeky things love a damaged grape to feed upon and with cool climates getting warmer, these pests are moving into regions previously too cool for them. Kevin Ker of Brock University told the International Cool Climate Symposium, “It’s a hitch hiker that we really don’t like but it will find a way to spread.”
It has been found in the US, Argentina, the UK, Czech Republic, Italy and Denmark, and it is thought it is more widespread but no-one’s owning up.
When the ladybirds inadvertently get harvested along with the grapes they emit a methoxypyrazine that smells of rancid peanut butter or bell pepper. Not something you’d want in your glass.
What’s worse, it’s pretty potent – as little as 1200 beetles per tonne can taint the batch. The sensory threshold is just 1 part per trillion.
“One the wine has been made, cleaning up the wine is virtually impossible,” said Ker.
So what to do about these pesky ladybirds?
Brock University researchers have discovered that potassium metabisulphite, which is used as an antioxidant in the winery has been found to be relatively successful.
Ker added, “If used pre-harvest, the wines made from vines treated with potassium metabisulphite seemed to be fairly successful. It can be used pre harvest to reduce the number of lady beetles below the sensory threshhold levels.”
However, anything that’s added to the grapes so close to harvest could be an issue.
What future for Wine Future?
Thursday 10 November
Wine Future is over for another two years.
Did things improve after the car crash first day?
Well, it didn’t get any worse. And there were some interesting insights worthy of a news story from Prosecco estimating it will quintuple in size by 2035 to one billion bottles plus some revealing statistics: Wine Intelligence’s Lulie Halstead revealed social media was relevant to just 13% of regular wine drinkers in the UK but 62% in China. Food for thought
On the last afternoon, I did a tour of the conference, getting folks’ opinions. The main benefit of the conference? Networking. How often do you get Jancis Robinson, Robert Parker and co. in the same room? It was a great opportunity to reconnect with contacts and old friends and meet new ones.
I am also much more knowledgeable about the Asian markets thanks to Jeannie Cho Lee, sommelier Yang Lu from the Peninsula, Shanghai and Don St Pierre Jnr of ASC.
The conference finished with a final debate on the ‘future of wine’ with an illustrious panel. Yet it failed to deliver any excitement. The conference should have gone out with a bang with the high profile names on stage but instead ended with a fizzle, with many shuffling out before the conclusion.
If there is to be a future for Wine Future (and there’s plans for Brazil 2013), exhibitors and other delegates have to speak out about the issues they had, not just confide that they agreed with what I said in my blog in a private moment (although thanks for the support)!
I want more debate, smaller break off seminars and less time allowing the biggest players in the industry to tell us about their company. What do you want?
Climate change and alcohol in the Napa Valley
Sunday 16 October
After rains all week in the Napa, the sun finally came out to dry out the fruit and hopefully ensure the 2011 crop isn’t riddled with rot. It was a particularly unseasonable week when I visited but the rains seem to follow me wherever I go. Perhaps drought-ridden areas should call me in…
So, a seminar on climate change between downpours seemed relevant. What is going on with the weather?
Napa Valley Vintners supported a study published this year breezily entitled ‘Climate and Phenology in Napa Valley: A Compilation and Analysis of Historical Data’ (!) in response to growing concerns about climate change.
Rex Stultz, industry relations director a the NVV, explains, “We started to see reports on USA today and NBC tying climate change to agriculture, saying that if the climate continued to change we might not be able to grow grapes in the Napa Valley.
“It created a bit of a stir in the community, asking if it was true.”
A two-year project followed to study the historical weather trends in Napa, and how this change affected wine grape growing.
Using 12,000 data collection points through the county, the study found that the Napa Valley had experienced warming but not to the degree that had been originally suggested.
Perhaps the problem was that the previous studies had been based on just two temperature collection stations. The first at the Napa state hospital, a facility for the criminally insane (not that that had any effect on the study but it’s a piece of trivia), which was positioned next to a road. The other station, in St Helena, was on the top of a fire station roof – not exactly representative of the county.
After studying some complicated-looking graphs, the results show that the average temperatures in Napa Valley have increased 1 to 2 degrees Fahrenheit over the past several decades, but considerably less warming than the fire station and mad house station had suggested.
Christopher Howell of Cain Vineyard & Winery said “Globally, the years 1998, 2005, 2006 and now 2010 were the warmest years on record, but they were some of the coolest for the Napa Valley. There is a suggestion by some climate scientists that, as the interior areas warm in the future, Napa temperatures may actually remain relatively moderate, or even cool as maritime air gets drawn further up the valley.”
But this doesn’t explain why so many wineries have alcohols into the high 14s and 15s. Winemakers claimed canopy management, lower hanging fruit, more efficient yeasts in the winery, rootstock selection and lower yields have resulted in higher alcohols.
However, in my opinion, late picking seems to be the main factor in these higher alcohol styles in Napa. There’s a bunch of producers that don’t have these high alcohols like Clos du Val and Corison, who pick a little earlier than most, proving that top Napa Cabernet doesn’t have to be horribly high in alcohol, and these producers are making some of the most attractive wines. So it’s not the climate; it’s all to often a human decision.
Consumers rightly concerned about lower alcohol wines
Wednesday 14 September
New research suggests the wine industry needs to address concerns about the quality and taste of lower alcohol wines if it is to attract more consumers to the category.
According to the study, commissioned by the UK’s Wine and Spirit Trade Association (WSTA), consumers are reticent about buying low alcohol wines, and I can’t say I blame them. The majority of low alcohol wines, German Rieslings excluded, are lacklustre. The consumer wine media has bagged most of them so it’s not surprising drinkers aren’t keen to try them.
The key findings were: 55% of red wine drinkers (51% of white wine drinkers) said they had concerns about the taste of lower alcohol wines while 41% of red wine drinkers (36% of white wine drinkers) had concerns about the product quality of lower alcohol wines
Jeremy Beadles, WSTA chief executive, says “While there’s plenty of evidence to suggest consumers are interested in lower alcohol drinks these findings suggest there’s work to do to convince drinkers about the taste and quality of products coming onto the market.”
I have not yet found one exciting wine that has been through an alcohol reduction process such as spinning cone or reverse osmosis and, winemakers need to address this problem. I suggest you either drink one glass fewer or drink Moscato d’Asti, German Riesling, Hunter Valley Semillon or Vinho Verde if you want to reduce your alcohol consumption.
Unfortunately, these wines are deeply unfashionable, and not particularly easy to understand for the average wine drinker. Residual sugar (Asti, German Riesling) or searing acid (Hunter Valley) makes most gluggers turn their nose up at them. But until the standard of the ‘low alcohol’ products coming on to the market improves, that’s the best low alcohol solution.
The findings emerge from the YouGov Omnibus Panel (August 2011) and are based on a sample of 1,693 British adult drinkers.
