New Report: Findings reveal that 70% of Cadillac Côtes de Bordeaux is “favorable’ to “extremely favorable’” for red wine production

Experts from the Bordeaux Science Agro have just revealed a report which includes mapping of the terroir’s potential. The main objective of this eighteen-month study is to evaluate the viticultural potential of the terroir of the Cadillac Côtes de Bordeaux appellation for red wines.

Other objectives of the study include:

  1. to preserve the great viticultural terroirs;
  2. improve winegrower’s knowledge of their terroirs;
  3. identify the soil and climate characteristics of the AOC;
  4. highlight the specific characteristics of the intercommunal area; and to
  5. improve viticultural practices in relation to the soil, and lastly, ensure the ecological transition of properties and enhance the landscape.

The aim of the study was to also analyze and map out the AOC, which is spread over 39 communes and covers 27,000 hectares, including an AOC area of 13,200 hectares.

This study was broken down into three phases, as follows:

  1. Construction of the model, modelization: Initial mapping showed that over 60% of the AOC area is in favorable or even extremely favorable zones;
  2. Validation of the model: consideration of geographical and non-geographical results following interviews with winegrowers. Non-geographical results: soil, exposure, topographical position, slope; and to
  3. Improvement of the model by experts.

Here are the findings:

Five zones were established from ‘not very favorable’ to ‘extremely favorable’, with

the less favorable areas being the zones of humid alluvial plains (locally known as ‘palus’), and deep valley bottoms. Moderately favorable areas are the plateaux of redoxic silty luvisols (hydromorphic silty ‘boulbènes’) and the areas of calcareous colluviosols at the palus/slopes interface. The most favorable areas are the slopes on ‘Agenais’ molassic formations, which are predominantly to the north. The east/west facing slopes on Agenais molasses are very favorable areas, as are the areas bordering plateaux, and hilltops too. And finally, the slopes on the predominantly southern Agenais molasses, as well as convex plateaux and gravelly outcrops bordering plateaux (known as ‘peyrosols’) are extremely favorable zones in our region.

In conclusion, the findings report that 70% of the region is “favorable” to “extremely favorable” zones for red production.  To take this even deeper, here are a few facts you need to know:

Gravelly soils are the hallmark of the appellation. These deep soils provide a significant water reserve, and their depth is an important asset when it comes to coping with climate change.

The most important thing to bear in mind about the terroir is its clay soil. Soils on molassic formations are good for making wines that can be kept for a long time or aging. Swelling clay soils are the best. They provide a balanced water supply that is ideal for the vines. But clay-limestone soils also have their advantages. They help to limit water supply, control nitrogen levels in the soil, and protect the vines.

Currently, it is still very difficult to map clay soils. The variability of molasses is not conducive to mapping.

“Soil management and the development of terroirs are major challenges for the sustainability of AOCs,” explains Chantal Larnaudie, President.

The ambition is also to bring new winegrowers on board (out of 14,000 hectares of AOC vineyards, only 7,000 are planted, and 1,900 are declared as Cadillac Côtes de Bordeaux).

Finally, this study will also enable us to select the best terroirs to produce dry white wines, sweet wines, and rosé wines as the Cadillac, Cadillac Côtes de Bordeaux, and Premières Côtes de Bordeaux PDOs are the only ones in the Bordeaux region to be able to claim all wine colors as PDOs, including crémants.

The ODG is also considering widening its specifications to include new colors now that scientific data are available.

Young red wine is found to be more beneficial than aged wine, study finds

A recent study of 16 wines from Australia and New Zealand has found levels of healthy antioxidants, existing mainly in red grapes, decreased significantly over time.

CQUniversity lead researcher Mani Naiker said the compound, trans-resveratrol, was proven to have cardiovascular, anti-inflammatory, and anti-diabetic effects.

“The more you consume this compound in your food or in beverages, it is perceived to give you better health benefits,” Dr Naiker said.

“When we compare younger bottled wines with mature red wines, we have proven that as the wine ages the concentration of this important bioactive compound decreases by about 75 percent over a 16-month period.

“That is a huge decrease in the concentration of this particularly important health-benefiting compound.”

Lead researcher Dr. Mani Naiker states that the compound is proven to have cardiovascular, anti-inflammatory, and anti-diabetic effects.

The study published in the Australian Journal of Grape and Wine Research, found the concentration decreased in some wines by as much as 96 percent.

After the initial resveratrol levels were measured, the bottles were resealed and stored in darkness in their original packaging.

“Irrespective to where we got the red wine from, which variety it was, the process of that compound, the loss was the same,” Dr Naiker said.

“I might just leave it with the French paradox that having a glass of red with a meal every day is good for your health.

“Now you know, you might want to go with a young red rather than an old one.”

Wine in a Can.  I’m a Fan!

What’s wrong with selling wine in a can?  It was not too long ago when traditionalists thought screw caps on wine bottles were a total outrage to an industry cloaked in tradition. And look at us now; twisting that screw cap with glee and patting ourselves on the back that the screw cap invention protected the cork trees.

Wine in a can is no gimmick. It began in about 2004 with Francis Ford Coppola Winery producing “Sofia”, a blanc de blanc sparkling wine in a can.  It has been growing steadily since then and canned wine was a $50 million business in the US last year. It seems to be falling somewhere between the box wine of student days and elegant, gifting wine in bottles.  We accepted beer in a can, followed by other premium beverages in a can like cocktails, sake, and craft beer, what’s stopping us from embracing the wine in a can trend?

So why is this new format drawing so many consumers?  Firstly, it is mainly the millennial generation that is attracted to wine in a can.  This grouping of people is usually drawn to products of convenience, accessibility, approachability, especially when purchasing wine.

Canned wine ticks all those boxes and so many more:

  • Ease of use: simple to take anywhere, takes up little space, is practically a single-serve unit, no mess
  • Environmentally friendly: the product has a lower carbon footprint because of transporting its reduced weight as well as space efficiency. Aluminum cans are also far easier to recycle than glass
  • Faster chilling: making this product practically instant
  • Adaptability: canned wine can be used in places where glass is normally banned like in parks and swimming pools
  • Price: due to reduced costs of packaging and transport

It is now a question of premiumization.  Consumers, especially the millennials do not want lower quality products, in any format.  The challenge is to prove that canned wine can exceed the consumer’s expectations and deliver a quality wine, regardless of its format.  One way is to encourage the consumer to drink the wine out of a glass and not from the tin.  There is still the old myth: “won’t it taste like metal?”.

Age ability is the other difference.  Wine in a can is meant for immediate consumption.  There are currently no trials or stats to see what the aging process in a can might be, so for now, the wine in your cellar will remain in a bottle, but the wine in your picnic hamper may well be in a can.

Stel + Mar sent us some samples of their wine in a can. The Stel + Mar strap line is “premium wine in a can” and I was not disappointed.

The Premium White is a 250ml Californian Chardonnay at 14.5% alcohol.  It is quite delightful.  I tasted it, enjoyed it thoroughly and poured the rest of the can into my glass to enjoy as I wrote this piece.

Tasting Notes: Aromas of fresh nectarine, lemongrass and a refreshing honeysuckle note make it a very appealing everyday tipple.

The Premium Red is a Californian Zinfandel and has classic varietal typicity.

Tasting Notes: Blackberries and rose petals with dark cherries and cinnamon.  It’s heavy enough to satisfy but light enough to glug.

I am a fan of wine in a can.  It’s a growing business and is to be ignored at your peril.

RECENT STUDY – RED WINE HELPS PREVENT HEART DISEASE

It’s well known that French men and women are less likely to suffer heart disease compared with Americans and some researchers speculated drinking red wine helps French people. How extactly red wine could help reduce the heart risk remains unknown though.

A study in the May 27, 2011 issue of European Journal of Pharmacology suggests resveratrol found in red wine and red grapes may be responsible for this reduced risk.

The study showed resveratrol helped prevent endothelial dysfunction in rats. Endothelial dysfunction is associated with hypertension and vascular oxidative stress or eventually cardiovascular disease.

In the study, Siddhartha R. Bhatt of the University fo Houston in Texas and colleagues treated some spontaneously hypertensive rats (SHR) aged 3 to 4 weeks with resveratrol in drinking water for 10 weeks. Some rats remained untreated as controls.

At the end of the study, the researchers found that compared to rats treated with resveratrol-added drinking water, rats untreated with resveratrol were more likely to have higher blood pressure, oxidative stress and reduced endothelium dependent relaxation.

On the other hand, rats treated with resveratrol lowered blood pressure; reduced hydrogen peroxide and increased superoxide dismutase activity, meaning that the oxidative stress was reduced; and normalized endothelium dependent vasorelaxation, nitrite/nitrate levels and nitrotyrosine content.

More importantly, according to the study, resveratrol treatment prevented the uncoupling of endothelial nitric oxide synthetase (eNOS) and scavenging of nitric oxide (NO), both of which would be otherwise observed in vascular diseases.

The study suggests that resveratrol can help prevent cardiovascular diseases including hypertension.

Food consumers do not have to drink red wine to prevent cardiovascular disease; resveratrol is now available as a dietary supplement.
