I’ve been seeing more wines labeled “Sustainable”, “Organic” and
“Biodynamic.” (And just when I finally learned that Petite Syrah isn’t a tiny Australian
wine!) Are any of these wines actually better for the environment? Our next
tasting will be the AWS National Tasting
Project and it’s based on these types of wines, so, people have been asking
me to explain the differences. It’s a good question and one that our members
may have answered at our tasting.
We sympathize with your confusion, though. Reading a wine label
is about as easy as deciphering a Mayan hieroglyph. Unfortunately, there’s no
simple solution for minimizing your eco-footprint. Many factors contribute to
an individual bottle’s overall environmental impact, including growing
practices, packaging size and type, and shipping distance and method.
With all three types of wine, the goal is the same: to make good
wine, that’s derived from good grapes that are grown in good soil and achieved
by going back to more traditional methods.
After World War II, scientists were working to improve our lives
by inventing things like polyester shirts and TV Dinners. The agricultural
industry got artificial fertilizers that promised to be labor-saving,
cost-effective and able to produce great results. Routine spraying and
additions of nitrogen, magnesium and potassium to vineyards left soil without life
and low in nutrients. Microbiologist Claude Bourgignon was quoted as saying
that some of the most famous vineyards in Burgundy had less microbiological
life than the Sahara because their soils were depleted by the use of chemical
fertilizers. Something had to change. Over the last thirty years, new approaches
have been adopted for many agricultural crops including wine grapes.
Organic Wine
Organic wine is wine made from grapes grown in vineyards that don’t
use synthetic chemicals, fertilizers, herbicides, fungicides and pesticides.
The idea is that the best grapes possible are used in the
manufacture of the wine. The soil is respected and biodiversity of the
environment is encouraged. Vines grow in soil rich in worms, insects and
bacteria. They grow cover crops of mineral rich plants, herbs and flowers. This
results in the soil being full of nutrients and trace elements that the vines
can absorb. The vines are also stronger, healthier and more resistant to
disease. Natural predators are added to the vineyard like ladybugs to tackle
aphid problems, birds to eat spiders or beetles, and chickens from mobile
chicken coops placed around the vineyard to eat grubs and vine weevils from the
ground.
Vegetarian wine is not necessarily organic. It is wine made
without the use of animal products at the fining stage. No egg whites or
fish-derived gelatins are used. It is certainly not, as explained to me by an obvious lunatic, "a wine that is
not suitable for serving with meat dishes."
Biodynamic Wine
For a vineyard to be considered biodynamic the grower must
follow the organic criteria plus some or all of the philosophies first published
in 1924 by Rudolf Steiner. At the request of the Austrian farming industry he
produced a series of lectures on an ecological and sustainable approach to
agriculture that increased soil fertility without the use of chemical
fertilizers and pesticides. His idea was to apply a holistic approach to the
farm where every organism contributes and has part to play in the "circle
of life." The farm should encourage biodiversity, be self-sustainable and
resist monoculture through cultivation of a variety of plants (vineyards are
normally monocultures as they grow just vines). It combines a planting, sowing,
harvesting and pruning regime determined by the position of the sun, moon and
planets. This approach, later refined by agriculturalist Maria Thun, provides
the basis to modern biodynamics.
It is the circle of life. Animals eat the plants and plants eat
the animals, everything is reduced to its basic carbon state and then rebuilt,
it’s a continuous cycle.
~ Alvaro Espinosa, Chilean biodynamic winemaker of Emiliana and Antiyal
Steiner outlined nine preparations (500-508). These are made from cow manure, quartz
(silica) and seven medicinal plants. Some of these materials are first
transformed using animal organs as sheaths (the animal organs are not used on
the vineyards). Of the nine biodynamic preparations, three are used as sprays
(horn manure, horn silica and common horsetail), and the other six are applied
to the vineyard via solid compost.
Preparations intended for sprays are mixed with water and go
through "vortexing" where the liquid is vigorously stirred in one
direction then another for up to an hour before use. This induces thickness to
the solution. Although there are some bizarre elements to the whole biodynamic
philosophy, most advocates don’t know why or how some of these preparations
work; but they claim that they do. Bodies such as Demeter will grant a
certificate for those reaching the criteria. Biodynamic growers see the vines
as just part of the whole operation. It is very much considered to be a
lifestyle choice for themselves, their workers and their livestock.
Things got much easier between myself and my cow when I looked
him in the eye and realized he genuinely wanted to help.
~ Bertie Eden, Château Maris, Minervois la Livinière
Rudolf Steiner's
Preparations 500-508
- COW MANURE -
Preparation 500: Cow manure is buried in cow horns in the soil over winter. The
horn is then dug up, and its contents (called horn manure or "500")
are then stirred in water and sprayed on the soil in the afternoon. The horn
may be re-used as a sheath. Stimulates soil life and root growth.
- QUARTZ - Preparation
501: Ground quartz is buried in cow horns in the soil over summer. The horn is
then dug up; its contents (called horn silica or "501") are then
stirred in water and sprayed over the vines at daybreak. The horn may be
re-used as a sheath. Enhances light metabolism and photosynthesis.
- YARROW - Preparation
502: Yarrow flowers are buried while sheathed in a stag's bladder. This is hung
in the summer sun, buried over winter, and then dug up the following spring.
The bladder's contents are removed and inserted in the compost (the used
bladder is discarded). Encourages uptake of trace elements.
- CHAMOMILE -
Preparation 503: German chamomile (Matricaria chamomilla) flowers are
sheathed in a cow intestine. This is hung in the summer sun, buried over
winter, and then dug up the following spring. The intestine's contents are
removed and inserted in the compost (the used intestine is discarded).
Stabilizes nitrogen and calcium and enhances soil life.
- NETTLES - Preparation
504: Stinging nettles are buried in the soil (with no animal sheath) in summer,
dug up the following autumn, and inserted in the compost. Stabilizes sulfur and
stimulates soil health.
- OAK BARK - Preparation
505: Oak bark is sheathed in the skull of a farm animal and buried in a watery
environment over winter, then dug up. The skull's contents are removed and
inserted in the compost (the used skull is discarded). Provides "healing
forces" to prevent disease.
- DANDELION -
Preparation 506: Dandelion flowers are buried, sheathed in a cow mesentery
(peritoneum). This is hung in the summer sun, buried over winter, and then dug
up the following spring. The mesentery's contents are removed and inserted in
the compost and the used mesentery is discarded. This stimulates the
relationship between silica and potassium so silica can attract "cosmic
forces" to the soil.
- VALERIAN - Preparation
507: Valerian flower juice is sprayed over and/or inserted into the compost.
Stimulates compost so that phosphorus will be properly used by the soil.
- HORSETAIL -
Preparation 508: Common horsetail (Equisetum arvense) is used to prepare
either a fresh tea or a fermented liquid manure; it is then applied either to
the vines (as a tea) or to the soil (as a liquid manure). Lessens the effect of
fungus.
Sustainable (Natural) Wine
This is the tricky one, the controversial one, and the confusing
one. There is no official or legal classification or standard set of operating
procedures, which makes natural wine hard to define.
Sustainable winemaking is a philosophy and a nose-to-tail approach to producing wine,
extending from vineyard to bottling. In general, organic and biodynamic
philosophies concentrate on the vineyard (and similar standards of care in the
winery), but with natural winemakers stricter, self-imposed standards exist. For
example, copper sulfate sprays and cultivated yeasts are never used in natural
wine.
The biggest misconception is about sulfur dioxide, which has
been used since Roman times as a disinfectant and an antioxidant. It is the
only additive used in natural winemaking, and then only in small quantities, and
only if the winemaker wants to. By the nature of this philosophy, natural
winemakers are small-scale, artisan operations that may risk their entire
year’s production by sticking to their principles, following an ancient method
that combines care in the vineyard and winery to produce the best product that
nature can provide.
So why does it provoke so much criticism? Robert Parker called
it "one of the major scams being foisted on the wine public." Is it
the lack of rules, even though they are very strict about what can and cannot
be done, or the fact that natural winemakers are called a "movement,"
yet deny such a movement exists? What about the wines themselves? There are many good natural wines, but there
are also cloudy, fizzy, oxidized, and faulty wines. Both seem to be acceptable to fans of the
philosophy. The Kool-Aid drinkers are especially worrying. A young sommelier quoted that
"Lafite-Rothschild is not a real
wine because they use sulfur."
An analogy
- Go to MacDonald’s and order the Chicken
McNuggets. This is Arbor Mist.
- Go to Giant Eagle and buy skinless, boneless
chicken tenders. They’ll be wrapped in
plastic on a paper tray. The origin, processing procedures, and additives will
be unknown. This is bulk wine.
- Go to Whole Foods and buy the best chicken they
have. It will be corn-fed and free-range. This is organic wine.
- Go to a butcher, the best you can find, and
buy his most expensive chicken. It will be corn-fed, free-range, and from a
small, local farm. The feet and head will still be attached. This is biodynamic
wine.
- Raise your own
chicken, kill it, pluck it and clean it. Then spit-roast it on an open fire. If
you have some chicken skills it will taste amazing. If not, you risk
salmonella, chewing on feathers and your friends thinking that you’re crazy.
But you won't care and will still insist it’s the best chicken ever. This
is natural wine.
