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.

Flu Virus Flourishes in Cold

Researchers have known for a long time that cold weather brings the flu season. But they
haven’t known exactly why. Now, they think they know why cold weather affects how
flu is spread. Mark Brush has more:


The researchers at the Mount Sinai School of Medicine found that once the flu virus is
airborne, it hangs around longer in cold air and low humidity. The virus doesn’t survive
as well in higher temperatures and higher humidity.


They tested guinea pigs infected with the flu virus – and found that the animals are more
contagious when they’re in a colder environment. They believe that’s because their bodies
don’t get rid of the virus as fast in cold temperatures.


Peter Palese is one of the authors of the report published in the Public Library of Science:


“So that makes sense when your grandmother told you ‘don’t go out when it’s cold, and
stay warm and you might get the flu,’ she was probably right.”


Palese says other research doesn’t support the use of vitamins to prevent the flu. He says
the best way to keep from getting it is to get a flu shot.

Growers Cover Up Local Produce

  • If the hydroponics trend continues, strawberries could be available locally everywhere. (Photo courtesy of the USDA)

It’s the middle of winter and you’re craving some fresh,
juicy strawberries. Go to your local grocery store and
you’ll find lots of packaged strawberries shipped from the
west coast or down south. For locally grown strawberries,
you have to wait till June if you live in the Midwest. But
that’s starting to change. Jennifer Guerra has the story:

It’s the middle of winter and you’re craving some fresh,
juicy strawberries. Go to your local grocery store and
you’ll find lots of packaged strawberries shipped from the
west coast or down south. For locally grown strawberries,
you have to wait till June if you live in the Midwest. But
that’s starting to change. Jennifer Guerra has the story:


I like strawberries. A lot. There’s strawberry rhubarb pie
for starters, strawberry and spinach salad, strawberry
shortcake. But I’ve been on this kick lately of trying to
buy only locally-grown produce, which is admittedly hard to do when you
live in the Midwest, especially with strawberries. Most of
the year, they’re shipped in from Florida and California,
but there is one place in Michigan were you can still pick
strawberries as late as October.


(Guerra:) “The redder the better…that’s too green”


It’s snowing out. I’ve got on the winter coat, the hat, the gloves,
and I’m picking strawberries with Kelly Bowerman.


(Guerra:) “So, which one is this?”


(Bowerman:) “This is a tribute. We have aroma, diamante, and
tribute. Aroma is a nice big berry, diamante’s even a bigger berry,
but it just don’t turn red, it’s oranged-colored, and tribute is smaller with a lot more
flavor.”


(Guerra:) “Alright, let’s get all three. Let’s get a
variety.”


Bowerman calls his strawberries three finger berries, which
he says are roughly the same size as the ones shipped in
from California


(Bowerman and Guerra try strawberries)


And frankly, the strawberries better taste
good, seeing as how Bowerman spent 60,000 dollars on them.


Well, not on the actual berries themselves, but on the
hydroponics system he uses to grow the berries. With
hydroponics, he still grows his strawberries outside, but
instead of planting them in the ground, the runners sit in
pots above the ground in a solution of warm water and
minerals. And since there’s no soil, the strawberries can
grow from June to October without the roots freezing over at
the first sign of cold weather. Still, there’s only so much
a hydroponics system can do on its own:


“He’s gonna find out that people want strawberries at
Christmastime, and so the next step will be to put a
greenhouse over that system and then we have 12 months.”


Merle Jensen is a professor of plant science at the
University of Arizona and he knows his hydroponics. He
knows growers all across the country who’ve started moving
their hydroponics systems inside greenhouses so they can
artificially light the crops. That way, they can produce
year round. But wait, there’s more:


“All of our leafy vegetables – high value fruits like
strawberries – will all be under cover in the next 5 years.
I’m sure of that. It’s a rapid expansion, not only in the
United States, but we see it in Canada, Mexico. So, this is the wave
of the future.”


A future that Jensen swears will taste delicious:


“You know what? I can say that because we can control the
nutrition, the salinity within the root system such that we can
program that product to have more acid and more sugars and better
flavor, and we can do that through hydroponics at will. And local growing is
becoming bigger and bigger all the time. It’s just got an
image of being better.”


Of course in the Midwest, “local” is still pretty relative.
Our Michigan farmer, Kelly Bowerman, says he gets people
from up to 50 miles away to pick his strawberries:


“One guy bought $28 worth of strawberries, and he said that ain’t
no big deal cause it cost me $40 worth of gas to
get here and back.”


And he’ll have to continue putting in that kind of travel
time if he wants to eat locally grown strawberries in the
middle of winter. Unless of course Jensen’s right and
hydroponic greenhouse systems really are the wave of the
future. If so, it might not be too long before Bowerman’s
strawberries show up year round at your supermarket.


Oh, and by the way, I liked the tribute strawberries the
best. They were my favorite.

Epa to Tune Up Fuel Economy Estimates

The Environmental Protection Agency is proposing to change the way it
calculates fuel economy estimates on the window stickers of new cars
and trucks. Consumer and environmental groups have been arguing that
the estimates don’t match up to real world driving. The Great Lakes
Radio Consortium’s Rebecca Williams reports:


The current EPA tests assume cars and driving conditions are the way
they were in 1985. The tests don’t factor in air conditioning, driving in
cold weather or driving any faster than 60 miles an hour.


The EPA says the new methods will lower the miles per gallon estimates
on most vehicles. The city estimates for conventional cars and trucks
could drop 10 to 20 percent. For hybrids, the city estimates could drop
up to 30 percent. A hybrid’s fuel economy is more sensitive to cold
weather and air conditioning.


Consumer groups say the new tests will give buyers a more accurate
picture of the car they take home.


Susan Pikrillidas is with AAA.


“We do honestly and truly believe that accurate labels will cause people
to buy more fuel efficient vehicles particularly in light of the high
gasoline prices.”


Under the proposal, the new test methods will begin with 2008 models…
so you could see the new stickers on cars as soon as fall 2007.

Upturn in Steel Market Extends Shipping Season

A rare extension of the shipping season through the Soo Locks at Sault Saint Marie,
Michigan is encountering the challenges of nature, but ships continue to plow their
way from Lake Superior ports to the lower Great Lakes. Mike Simonson reports for
the Great Lakes Radio Consortium:


An unusually high demand for domestic iron ore from northern Minnesota and
western coal from Montana and Wyoming caused the U.S. Army Corp of Engineers
to keep the Soo Locks open an extra ten days. Weather permitting, they’ll try to
keep the locks open until January 25th.


Glen Nekvasil is with the Lake Carrier’s Association in Cleveland. He says this
won’t become an annual extension.


“This is a one-time request. The steel industry had a late surge in 2003, especially
seeing the tariffs on imports are gone, we just could not take a chance on letting that
momentum slip away because 2004 is a whole new ballpark for them. We got to start
out with every advantage we can.”


The U.S. Fish and Wildlife Service and Michigan Department of Environmental
Quality all had to agree to the extension, since they say plowing ice flows can cause
environmental disruption.
