Natural Selection (Jan - 2010)

Hahn Family Wines in California

Any winemaker worth their salt, and a place on The Society's List, has a vested interest in nurturing the soil that affords them a living. One of the problems with grape growing is that it is a monoculture and as such is naturally prone to attack from pests and diseases. How growers deal with these and encourage more biodiversity in their vineyards is the theme explored in the new List. We thought members might be interested to see some of these efforts in practice.

Hahn Family Wines

Hahn Family Wines in California's Napa Valley have recently achieved certification for the Sustainability in Practice (SIP) Vineyard Program – a comprehensive and verifiable method to authenticate commitment to integrated farming practices and the environment. Biodiversity is encouraged providing habitat for wildlife like this bobcat. Nikita, a lanner falcon, is used to keep grape-eating starlings away in an environmentally friendly way.

The Bekaa Valley in the Lebanon, home to Chateau Musar's vineyards

The Bekaa Valley in the Lebanon, home to Chateau Musar's vineyards, is virtually frost and disease free, so it is no surprise to learn that the property is certified organic. But even here, Mother Nature is capable of surprises. The 2009 vintage will go down in history as the year of the late September deluge – unprecedented since records began in 1870. Fortunately most of the grapes had been gathered in and, as Gaston Hochar reported to members at a tasting in November, 'the only thing that was damaged was our pride concerning our presumption that rain never falls during the harvest in Lebanon.'

Guinea Fowl for Pest Control

Society buyer Jo Locke says that, 'Guinea fowl for pest control are a charming and very attractive sight in vineyards in South Africa. More so than the electric fences which many have to resort to in order to keep out the marauding baboons!' Bon Cap, suppliers of The Society's Pinotage, have been farming organically for years. They go to great trouble to obtain natural fertilisers, such as penguin guano and plant nitrogen-rich cover crops, such as lucerne and lupine between the rows. The photo is of a new block of pinotage vines, needed to supply members' increased demand for The Society's Pinotage.

Seresin Estate

Seresin Estate in Marborough, New Zealand

Seresin Estate in Marborough, New Zealand, were one of the first to embrace organic viticulture in the region. They now use biodynamic practices across much of the estate too. They have adopted many innovative techniques, but owner Michael Seresin says that what they are doing is, 'in essence traditional agriculture'. After seeing horses pulling ploughs in vineyards in France and Italy, the estate developed a horse-drawn sprayer to spread seaweed and compost teas over the vineyards. Stewart, a retired trotter, does the same work as an 80-horsepower tractor, resulting in less compaction of soils and fewer carbon emissions, and he can live off home-grown fuels such as grass and oats.

El Polilla

The El Polilla range of wines has been produced from organically farmed grapes especially for The Society by Alvaro Espinoza of Viñedos Organicos Emiliana. Alvaro is a pioneer in Chile, championing organic and biodynamic viticulture to enhance the expression of terroir in wines. Leaving flowers to grow and wintering llamas in the vineyards helps to encourage biodiversity. El polilla, means moth, Alavaro's nick name.

Domaine de l'Arjolle

Louis-Marie Teisserenc of Domaine
de l'Arjolle in the Languedoc

Louis-Marie Teisserenc of Domaine de l'Arjolle in the Languedoc is a leading proponent of lutte raisonnée. This is a viticultural approach based on integrated pest management and minimal intervention. He has been confusing bugs sexually for many years now (with the use of pheromones!)

4.4. Cookie Policy

By using The Wine Society website, you agree to cookies being used in accordance with the policy outlined below. If you do not agree to this, you must alter your browser settings to turn off cookies or block those types which are unacceptable to you or cease using the website.

The Wine Society uses cookies to enable easy navigation and shopping on the website. We take the privacy of all who use our website very seriously and ensure that our use of cookies complies with current EU legislation. The following guide outlines what cookies are, the types of cookies used on The Society's website and how they work.

You may alter your browser settings to turn off cookies or block those types which are unacceptable to you, but this will cause difficulties when accessing and using some areas of the site. Instructions on how to do this can also be found below.

4.4.1. What are 'Cookies'?

  • Most major websites use cookies.
  • A cookie is a very small data file placed on your hard drive by a web page server. It is essentially your access card, and cannot be executed as code or deliver viruses. It is uniquely yours and can only be read by the server that gave it to you.
  • Cookies cannot be used by themselves to identify you.
  • The purpose of a basic cookie is to tell the server that you returned to that web page or have items in your basket. Without cookies, websites and their servers have no memory. A cookie, like a key, enables swift passage from one place to the next.
  • Without a cookie every time you open a new web page the server where that page is stored will treat you like a completely new visitor.
  • More recently, cookies have also been used to collect information about the user which allows a profile of their preferences and interests to be created so that they can be served with interest-based rather than generic information about available goods and services.

4.4.2. How do Cookies help The Wine Society?

Cookies allow our website to function effectively. Cookies also help us to arrange content to match your preferred interests more quickly. We can learn what information is important to our visitors, and what isn't.

4.4.3. How does The Wine Society use cookies?

The Wine Society does not accept advertising from third parties and therefore, as a rule, does not serve third-party cookies. Exceptions to this include performance/analytical cookies (see below), used anonymously to improve the way our website works, and occasions when we may team up with suppliers to offer special discounts on goods or services.

The Society uses technology to track the patterns of behaviour of visitors to our site. In this instance we use cookies of the types described in below (which are removed at the end of your session) and in below (which are removed after 14 months). These are always served as first-party cookies, operated by The Wine Society, not a third party.

4.4.4. What type of cookies does The Wine Society use?

We use the following three types of cookies: Strictly Necessary Cookies
These cookies are required for the operation of our website, enabling you to move around the website and use its features, such as accessing secure areas of the website. Without these cookies, services like shopping baskets or e-billing cannot be provided. Under this heading, we currently use the following cookies:

  • Authentication Cookie and Anonymous Cookie
    These cookies remember that you are logged in to your account – without them, the website would repeatedly request your login details with each new page you visit during your time on our website. They are removed once your session has ended.
  • SessionID Cookie
    This cookie is used to remember who you are as you use our site: without it, the website would be unable to tell the difference between you and another Wine Society member and facilities such as your basket and the checkout process would therefore not be able to function. They too are removed once your session has ended. Functionality & Targeting/Tracking Cookies
These cookies are used to recognise you when you return to our website and to provide enhanced features. This allows us to personalise our content for you. Under this heading, we currently use the following cookie:

  • Unique User Cookie
    This cookie is used to:
    • store your share number in order to identify that you have visited the website before. Without this cookie, we would be unable to tell whether you are a member or not.
    • record your visit to the website, the pages you have visited and the links you have followed. We use this information to make our website, the content displayed on it and direct marketing communications we may send to you or contact you about more relevant to your interests

This cookie expires after 14 months. Performance/analytical cookies
These cookies collect information about how visitors use a website, for instance which pages visitors go to most often, and if they get error messages from web pages. These cookies don't collect information which identifies a visitor. All information these cookies collect is aggregated and therefore anonymous. It is only used to improve how a website works. Under this heading, we currently use the following cookies:

  • Webtrends Cookie
    This is a first-party cookie enabling Webtrends to track, anonymously, where you visit throughout the site. Using Webtrends allows The Society to better understand how members use our site and monitor website traffic.
  • Google Analytics Cookies
    These are third-party cookies similar to the above, but used to enable Google Analytics to monitor website traffic. Like the Webtrends cookie, all information is recorded anonymously. Authentication Cookie
In order for us to ensure that your data remains secure it is necessary for us to verify that your session is authentic (i.e. it has not been compromised by a malicious user). We do this by storing an otherwise meaningless unique ID in a cookie for the duration of your visit. No personal information can be gained from this cookie.

4.4.5. How do you turn cookies off?

All modern browsers allow you to modify your cookie settings so that all cookies, or those types which are not acceptable to you, are blocked. However, please note that this may affect the successful functioning of the site, particularly if you block all cookies, including essential cookies.
