The Wine Cellar
Grapes are placed inside the
grape crusher where
stems are first removed.
Next, the heterogeneous
mixture is transferred to
the bladder press where
the grapes are crushed to
release juices high in?
Fructose C6H12O6
At the bladder press, the
skins of the grapes are
removed to produce white
wines. Red wines contain
skins reintroduced back
into the mixture after
pressing. Red wines taste
bitter due to tannins from
the skins. The chemical
name for tannin is?
C76H52O46 Tannic Acid
Red Wines
After pressing, the wines
are placed into giant
holding tanks. Here,
yeast is added and
fermentation begins.
What is produced in
C6H12O6  2C2H5OH + 2CO2
carbon dioxide
Blush Wines
After being exposed to
tannins, red wines are
transferred to barrels
while the white and
blush wines age inside
of fermentation tanks
such as this one. How
many liters does it
1000gallons =
3785L Wow!!
Red wines are placed inside of
these barrels for periods
ranging from 6-9 months.
The temperature must
remain 55-60°F or
conditions may become
favorable for unwanted
bacteria to grow rapidly
through binary fission!
How rapidly?
>500 strands/12hr!!
After months of aging,
wines are pumped from
the cellar to the
animated bottling room.
Here, bottles are first
sterilized then the wine
is poured in and sent to
the corking machine.
Who discovered
Louis Pasteur
The bottles are filled with
nitrogen gas N2 to ensure
no air containing bacteria
is introduced into the
wine. The wine is finally
corked and sealed for
freshness to keep out
unwanted bacteria. How
long does the entire
process take?
10-18 months
Whites = short time
Reds = longer time
Ice Wine?
Stacked on top of these crates
are cases of Ice Wine ready
for shipment to Japan &
Asia-the largest consumers.
Ice Wine is a rare and
expensive desert wine that
is produced only in two
areas of the world! Why?
Perfect Climatic
Making Champagne
This bottle of Champaign
was produced last year.
Champagne is made from
the Chardonnay grape.
The only difference
between Chardonnay -a
white wine- and
Champagne is?
Chardonnay + CO2  Champagne
Why are Champagne
bottles rotated?
Champagne, unlike other
wines is aged inside the
bottle. The bottles must be
rotated with the bottle
neck pointed down 1/3
turn every 8 hours. This
machine automatically
accomplishes that task.
Debris removed?
Wow! That’s
Once the debris is
concentrated at the
neck of the bottle it is
removed. How is the
debris removed
without allowed carbon
dioxide (bubbles) to
N2 (l)
Wine Tasting Steps
1 Hold the glass up at an angle
into the light and check for
clarity-should appear clear,
some debris is normal.
2 Swirl the wine and check for
the legs. This step releases
the esters that produce
aromas characteristic to the
wine. -The longer they hang
before falling, the higher the
alcohol content.
3 Smell the bouquet -Think
of fruity smells.
4 Cleans the palate-Take a
small/quick drink.
5 Chew the wine-Take a small
amount and move inside the
mouth like mouthwash,
thinking of different aromas
characteristic to the wine.
