Wine makers are shaking things up in their vineyards. Some of them use natural and organic methods to control pests and weeds instead of using pesticides. Now, one winery has discovered a unique, natural way to prune their grape vines. Joyce Kryszak visited the winery to get a first hand look:

At the Featherstone Winery in Southern Ontario there are 20 acres of perfectly manicured grape vines. They stretch out in neatly groomed rows across rolling green hills.

But no man or machine maintains this vineyard. There are 40 cute, little, wooly lambs on duty pruning the grape vines into tip-top shape.

David Johnson says he knows the idea of using lambs on his vineyard is a bit odd. Johnson thought so too when he first heard the idea. He found out about it visiting wineries in New Zealand.

“I didn’t believe them at the time. I thought they were having fun with a tourist and that this would be a big joke, some Canadian when he went back home, telling a story. So, yeah, I’ve taken a ribbing on the lamb thing, for sure.”

But Johnson ignored the jokes and decided to try it out.

His wife Louise Engel admits they were a little nervous at first setting the lambs lose in their valuable vineyard.

“We watched these lambs like hawks. I mean, all the staff were sitting out there and following them around – ‘did they eat any grapes, did they eat any grapes?’ But they didn’t. They’ve got very nimble little mouths and little teeths and little lips and they just eat around them.”

You see, pruning grape vines is delicate business. Only a targeted area of leaves is removed from the lower part of the vines to help the fruit grow better.

But Engel and Johnson say the lambs are perfectly designed to handle the job. The young, spring lambs aren’t tall enough and their necks can’t stretch up to reach the grapes. And, since they only weigh about 50 pounds, they don’t trample the soil. And, yes, their droppings do make excellent organic fertilizer.

(sound of lambs bleating)

Three years, and three flocks of sheep later, nobody’s laughing. Area vintners even have copied them; and for good reason. It would cost about $300 an acre to hire seasonal workers to come in for seven weeks in the summer to hand prune the vines. The lambs cost a fraction of that. And, when the pruning is done in August, off they go to the butcher.

Johnson says it turns out that free-range lambs fed a diet of grape leaves end up being pretty tasty.

“We sold them off last year to some caterers and some pretty nice restaurants, and they got back to us and said, ‘wow, these lambs are really special.’ They’re different; they’re almost veal-like in color and flavor and very, very lean. And they’re going to do lamb specials all month and pair it with our wines all month.”

But he admits there are some drawbacks.

They had a tough time finding enough lambs to do the job. There are about fifty million of them in New Zealand. But, it turns out, they’re kind of sparse in Ontario.

Johnson says there are some logistical problems, too. Even some organic pesticides are toxic to lambs. And, there’s all that fence building and moving around to limit the lambs’ access, so they don’t over-prune.

Still, they think it’s worth the hassle. Engel says the lambs fit in beautifully with their philosophy of sustainable farming and diversity in the vineyard.

“They’re lovely, tranquil, placid things, and there’s something almost biblical about having lambs roaming the place and wine here. And, it’s just, I don’t know, there’s just some itch that scratches that’s quite fulfilling.”

People visiting the vineyard enjoy watching the lambs too.

Customers enjoy lunch on the veranda as they look out on the pastoral scene. And, of course, they have a little wine. And one of the top selling wines is Black Sheep Reisling.

Nature and Ice Wine

When you think about wine you might think about sunny Italy or warm
Napa Valley in California. But one wine is the product of cold
weather. Ann Murray has the story:


Today, the weather and the sales are brisk at the Mazza Winery and
Vineyards.


Sales Person: “Did you want these in a bag?”


Mary Ventura: “Yes, this is all going to the same spot.”


Mary Ventura is buying small bottles of wine that she describes as
“liquid candy.” Ventura and the sales clerk chime in when I ask her
what she’s talking about:


“This is ice wine. It’s not something you can find on all the shelves.
And so we came across this little winery and it’s great.”


Mazza’s is one of the few wineries in the United States that sells and
produces ice wine. More and more people are discovering this rare,
super sweet dessert wine:


“We’re going to head out right behind the winery, actually.”


Mario Mazza is a third generation grower. He says their vineyard’s
location along the Lake Erie shoreline in Pennsylvania makes ice
wine production possible. For vineyards in this region, the Great Lake
changes the local climate:


“In the spring it keeps the shore a little bit cooler, keeps the grapes
from budding too early, which is a good thing… prevents them from
getting hit from the later spring frost. In the fall, we have the reverse
happen. In September and even in October we have a little bit more
warmth along the lake shore here.”


But the real ticket to producing ice wine is a final burst of cold winter
weather. In December or January, winds off Lake Erie can bring the
temperature to well below freezing. As snowflakes whip around the
vineyards, Mazza stands next to rows of grapes still on the vine. The
rows are netted by hand to protect the vines from high winter winds
and hungry animals:


“These vineyards we’re looking at here are vidal blanc grapes.
They’re a great variety because they have a relatively thick skin and
can hold up to the colder climate, to the colder weather and leaving
them on the vine for an extra two months.”


Natural ice wines require a hard freeze to occur sometime after the
grapes are ripe. If a freeze doesn’t come fast enough, the grapes
might rot and the crop will be lost. If the freeze is too severe, no juice
can be extracted.


(Sound of bottling inside winery)


Back inside the winery, Mazza helps out with bottling. During a break,
he says that catching the right sustained freeze means that workers
must be ready to roll out of bed early to pick the grapes used in ice
wine:


“When we go out there and pick ’em about 5:00 in the morning with
headlights down the rows, you’re actually picking these grapes at
about 18 degrees Fahrenheit so they’re actually frozen, just like a marble.
You get very, very sweet juice when you press that out.”


Ice wines are very sweet because the grapes dehydrate the last two
months on the vine. That concentrates the sugar and the flavor:


“The sugars are twice that we get in a normal harvest date in October. And
the flavors are just so much more intense and concentrated.”


Murray: “So you don’t end up with a lot of juice then?”


Mazza: “Hence the rarity, the sale in a smaller bottle and the price
tags on ice wines. A lot of people look at them and say wow, those are
awfully expensive. When they learn about the extensive effort put into
making these wines, they then understand that it’s well worth it.”


At $40 dollars a half-bottle, ice wine generally is worth the extra work
for growers. It might take months to completely ferment ice wine.
Regular wines take days or weeks. Each year, the Mazzas produce
only about 250 gallons of ice wine — a tiny amount compared to other
wines.


Worker: “There should be about a case down there.”


Upstairs, customers continue to stream in and out of the Mazza wine
shop, some of them eyeing the small bottles of liquid gold that nature
and patience help make possible.

Cut in Farm Subsidies Might Hurt Midwest Vintners

Votes from many of Ohio’s farmers helped President Bush win re-election last year.
Now many of them feel betrayed because the President’s 2006 budget proposal calls for
federal agriculture spending to be cut by nearly ten-percent. The cuts would drastically
reduce farm subsidies… and they would curtail agricultural research efforts. The Great
Lakes Radio Consortium’s Kevin Niedermier reports that would be an especially big
problem for a fairly new crop in the Midwest…grapes for wine:


President Bush wants to cut agriculture spending by more than eight billion dollars as he
looks for ways to reduce the federal deficit. If Congress approves the proposed cuts,
agricultural research at all of the nation’s land grant universities would suffer. For
example, Ohio State University’s Agriculture Research Center in Wooster, Ohio, would
lose six-million dollars. Director Steven Slack says, when you multiply that reduction by
all the research universities across the region… it could mean a lot of cuts.


“If that budget goes through this October, we would see an impact that would reduce
about 200 faculty positions, about 400 staff positions, and about 550 graduate students
that are supported in the north central region, and these are the states from Ohio to the
east and Iowa to the west.”


One of the newer ag industries that has benefited greatly from federally supported
agricultural research is America’s wine producers. For instance, university research into
“bio-dynamic” farming can help vineyards produce wines that don’t rely on synthetic
fertilizers, pesticides or fungicides. Instead, it uses natural methods. It’s like organic
farming…. only it limits the materials used to grow a crop to the farm on which the crop
grows. It’s a closed system.


Under the President’s budget, that kind of research and much more would be cut
at a time when the Midwest wine industry is just getting a good start.


During the last few decades, U.S. wineries have grown from a few hundred, to more than
35, 000 according to the Ohio Wine Producers Association. Most of them are small,
family run operations.


Near the Lake Erie shore just outside Cleveland, Lee Kling-Shern runs the
ten-thousand gallon a year Klingshirn Winery. As wineries in this part of the world go…
his is an old one. His grandfather began growing grapes and making wine on this farm in
1937. Klingshirn says federally funded research made it possible for Midwest vineyards
to grow better varieties of wine grapes…like Viniferas.


“And it’s only been in the last 30 years that technology and research has brought
recommendations to ambitious growers like ourselves to explain how best to handle these
tender varieties and make them work in the field. And thus, today our business is now at
a competitive level with other wine-producing areas of the world as far as the varieties
that we can produce and the quality that we can make. And allows us to be something
worthwhile to come see and do and experience.”


Like Ohio wineries, vintners in states such as New York, Michigan, Illinois, and Missouri
have turned out higher and higher quality wines. Klingshirn is worried that federal cuts
to research spending will make it harder for small vineyards to stay competitive….


“There was finally a research development operation slated to be built at Cornell-New
York which would apply to our style of viticulture here, that as far as I understand has hit
the trash can at this point. So, that’s something we’ve needed for years and years and
years and just as we’re on the cusp of getting it, it’s pulled away.”


Klingshirn and other vintners are also upset that the Bush budget proposes a fifty dollar
fee be paid by winemakers anytime they change the label on a bottle. The money would
be used to pay inspectors who make sure the new labels meet federal standards for health
warnings and other required information.


The vineyard owners and winemakers say the new fees and research cuts are bad timing
for the wine industry in the Midwest, just as many of the vintners were beginning to win
gold medals nationally and internationally.


They’re afraid their progress will be tarnished by the Bush Administration’s proposed
budget.

Winemakers Bugged by Asian Beetle

  • The Multicolored Asian Lady Beetle was introduced in 1916 to control aphids. It has since established populations around the country. (Photo courtesy of the USDA)

Many people in North America have already met the multicolored Asian lady beetle. It looks like an ordinary ladybug, but it has some bad habits. It stinks, it bites and it invades homes when the winter approaches and stays there until spring. And not only is it a pest in our houses, it has decided that it likes wine too.

Many people in North America have already met the multicolored Asian lady beetle. It
looks like an ordinary ladybug, but it has some bad habits. It stinks, it bites and it
invades homes when the winter approaches and stays there until spring. And not only is
it a pest in our houses, it has decided that it likes wine too. The Great Lakes Radio
Consortium’s Victoria Fenner has the story:


Ann Sperling goes out to the vineyards every day to check for bugs. She’s the vintner
with Malivoire Winery. Malivoire is a small organic winery in the Niagara Peninsula in
Southern Ontario, just north of the New York State border. There’s one kind of bug in
particular that Ann is hoping she doesn’t see – the multicolored Asian lady beetle.


It was introduced to North American in 1916 to control help aphids on plants. In 1988 in
Louisiana, the ladybug population suddenly started to grow. Scientists still don’t know
what happened to make them reproduce so fast at that time. But in only six years, it
spread as far as the northern states and southern Canada.


The spread of the bug has been very bad for the grape and wine industry. Sperling is
nervous about these ladybugs because she was caught by surprise a few years back. She
didn’t know anything about the problems they would cause to her wine at the time.


“Typically there is a certain number of insects including wasps and things like that that
are harvested with the fruit and it doesn’t cause any problems in the processing. And in
2001 there were these Asian lady beetles and they infected, or affected, the flavor of the
wine, so that there were many wines from that vintage throughout the Niagara peninsula
that had the characteristic flavor and were not saleable.”


The big problem is that Asian ladybugs are the skunks of the insect world. Just like
skunks, they give off a bad smell to discourage predators. And they release a sticky
brown substance from the joints in their body when they’re stressed and they make a real
mess.


At harvest time, there’s a lot of commotion in the vineyards. That’s when the bugs get
really upset, and they leak all over the grapes. They also hang on to the grape clusters
and are pressed into the wine along with the fruit. Sperling says they had to dump half of
their 2001 vintage because it had a bitter taste and a bouquet of raw peanuts.


Because of this, the multicolored Asian Ladybug has become a big problem for wineries
in the Great Lakes region and in the Midwest. It’s such a pressing problem for the wine
industry that the Ontario Grape Growers Association has set up a special task force to
figure out what to do. Gerry Walker is heading up the task force. He says the ladybug
isn’t a problem this time of year, but the populations are being monitored to head off
potential problems during the harvest season.


“First of all, the bug usually is outside the vineyard for most of the season. It’s usually
located in soybean fields or forested areas. It has a wide host range in terms of what
aphid species it will feed on. It primarily feeds on aphids during the growing season,
populations build up and at the end of the growing season when cool temperatures occur
it cues the bug to look for hibernating wintering sites and also to fill up on sugars in order
to hibernate. And so they move to the vineyards as the grapes begin to ripen.”


Asian ladybugs are found across most of the southern part of North America –
everywhere that there is an aphid population.


And there is a connection between soybean fields and vineyards. Here’s why – aphids
like to eat soybeans, and the multicolored Asian ladybeetle likes to eat aphids. When the
soybeans are harvested, the beetles look for new food and move to the vineyards.


Mark Sears is an environmental biologist at the University of Guelph. He’s beginning a
study to find out the movement patterns of the ladybug. He says we can’t get rid of them.
All we can do is control them.


“This beetle’s been here long enough that there’s no way we’re going to eliminate it. We
just want to suppress its numbers so that it isn’t a problem, in this case, in the vineyards.
If we do a good job of suppressing aphids – we’re not going to eliminate them either, but
if we keep them at lower numbers then there’s less food available for beetle populations,
there will be fewer of them to move to vineyards. And therefore we should be able to
contain the problem, not the insect itself.”


Ann Sperling is one of many winemakers who’s happy to see that this major study of the
ladybug is being done. But the invasion of 2001 was also a valuable learning experience.
Sperling says they’re ready if it happens again. Malivoire Winery has bought a shaker
table to dislodge the bugs from the bunches of grapes. They’ll also hire more people to
sort the grapes by hand.


Some people in the wine industry don’t like to talk about the multicolored Asian ladybug.
They’re afraid of tainting the reputation of their wines. Ann Sperling agreed to talk about
it because she thinks there wouldn’t have been as much damage to their 2001 vintage if
they had been better prepared. They haven’t had any big problems since then.


If another large invasion happens now, Malvoire Winery is ready. Ann Sperling hopes
other wineries will learn from their experience.

Regional Winemakers Worry About Disease

Some winemakers are battling a disease called "black goo." It’s caused

Some winemakers are battling a disease called “black goo.” It’s caused by a fungus that leaves infected grape vines stunted and weak. As teh Great Lakes Radio Consortium’s Wendy Nelson reports, no one’s sure where the disease is coming from, or where it might turn up:


Black goo has claimed an estimated nine-thousand acres of vines in California. That’s only about one percent of the state’s vineyards. But so far, there’s no cure; the only thing growers can do is rip up the vines and replant.


Ironically, some think the ever-growing popularity of California wines may be contributing to the problem.


“In other years, some of the weaker vines would have been thrown away.”


Wayne Wilcox is a professor of plant pathology with Cornell University.


“One of the prevailing theories is that this disease – the fungi that are causing it – are preying on some of these weaker vines.”


Wilcox says there have been a couple of isolated reports of black goo outside of California, including one case in New York. But he says Great Lakes winemakers shouldn’t panic. Instead, Wilcox advises them to examine vines carefully and reject any that look weak.
