Narrator: AUTOMATIC SLIDING DOORS

ARE THE NORM AT MOST SUPERMARKETS

AND LARGE RETAILERS.

SENSORS DETECT YOUR APPROACH

AND PROMPT THE DOORS TO SLIDE OPEN.

THEY OPEN WHEN YOU ARRIVE AND CLOSE WHEN YOU DEPART,

WHICH IS CONVENIENT WHEN YOUR HANDS ARE FULL.

THESE AUTOMATIC SLIDING DOORS

ARE CUSTOM-MADE TO FIT THE CUSTOMER'S DOOR OPENING.

THE DOORS ARE PROGRAMMED TO OPEN IN 1 1/2 SECONDS,

BUT THAT CAN BE ADJUSTED DURING INSTALLATION.

THE DOOR STRUCTURE AND FRAME ARE MADE OF ALUMINUM

THAT'S BEEN HEATED TO A SOFTENED STATE.

IT'S THEN FORCED THROUGH A DIE TO GIVE IT A SPECIFIC SHAPE.

A COMPUTER-GUIDED SAW CUTS THESE ALUMINUM PIECES

TO THE LENGTH REQUIRED FOR THIS ORDER.

THIS IS ONE OF THE PIECES

THAT WILL FORM THE VERTICAL SIDE OF THE DOOR STRUCTURE.

WORKERS INSERT DURABLE WEATHER STRIPPING

INTO A BUILT-IN TRACK.

THEY COLLAPSE THE END TO LOCK THE STRIP IN PLACE.

ON THE OPPOSITE SIDE, THEY FASTEN LONG, THREADED RODS.

THE RODS ARE USED TO ATTACH THE RAILS.

THE RAILS FIT OVER THE ROD

AND ARE SECURELY FASTENED TO THE DOORFRAME

WITH AN ALIGNMENT CLIP AND NUT.

ONCE WORKERS HAVE ASSEMBLED THE TWO DOOR STRUCTURES,

THEY INSTALL A PIVOT AT THE TOP OF EACH ONE.

THIS TOP PIVOT ALLOWS THE DOOR TO SWING OUTWARD

WHEN YOU PUSH THE EMERGENCY EXIT BAR.

THEN, THEY ASSEMBLE THE DOOR HANGER.

IT CONNECTS THE DOOR TO THE TOP OF THE FRAME.

THE HANGER ROLLS ON TWO WHEELS.

A URETHANE RUBBER ONE ALLOWS THE DOOR

TO MOVE SIDEWAYS ALONG THE TRACK...

AND A PLASTIC ONE, WHICH PREVENTS THE DOOR

FROM GOING OFF THE TRACK.

THEY ATTACH THE DOOR'S TOP PIVOT TO THE HANGER.

AN ACCESS CONTROL RELEASE IS NEEDED TO OPEN THE DOORS

IN CASE OF EMERGENCY.

WORKERS INSTALL IT INTO SECTIONS OF THE DOORFRAME

THAT MEET WHEN THE TWO DOORS CLOSE TOGETHER.

WHEN YOU PUSH THE EMERGENCY BAR,

THIS MECHANISM ROTATES TO LET THE DOOR SWING OPEN.

THE HANGER DETENT PREVENTS THE DOOR FROM SWINGING OPEN

DURING NORMAL OPERATION.

IT ATTACHES THE ACCESS CONTROL RELEASE

TO THE DOOR HANGER.

WORKERS COMPLETE THE DOOR STRUCTURES

BY APPLYING LEGALLY REQUIRED SAFETY DECALS.

MEANWHILE, AT ANOTHER STATION, WORKERS INSTALL

THE DOOR'S ELECTRONICS IN THE HEADER.

THIS IS ONE OF THE MANY INFRARED SENSORS

THAT TRIGGER THE DOORS TO OPEN.

THE SENSORS DETECT PEOPLE APPROACHING

BY READING THE INVISIBLE HEAT ENERGY HUMANS GIVE OFF.

AFTER LOADING THE NUTS, THEY'LL NEED TO FASTEN

THE REMAINING COMPONENTS TO THE HEADER'S TRACK.

THEY INSTALL A PULLEY,

PART OF THE DRIVE SYSTEM THAT MOVES THE DOORS.

THEN, THEY SLIDE THE HEADER'S COVER INTO A TRACK

AND CONTINUE INSTALLING COMPONENTS...

FIRST, THE END CAPS,

WHICH ATTACH THE HEADER TO THE DOORFRAME,

THEN, THE DOOR CONTROLLER, THE BRAINS OF THE ENTIRE SYSTEM.

IT HAS BUILT-IN OPERATIONAL SOFTWARE.

YOU CAN RUN THE DOORS ON THE DEFAULTS

OR CUSTOMIZE THE SETTINGS.

NOW, FOR THE REST OF THE DRIVE SYSTEM.

THEY INSTALL AN ELECTRIC MOTOR AND PULLEY.

THE MOTOR HAS A SWITCH THAT DETECTS THE DOOR'S POSITION.

NEXT, A TIMING BELT IS LOOPED AROUND TWO PULLEYS.

THEY ADJUST THE DISTANCE BETWEEN THE PULLEYS

TO TIGHTEN THE BELT.

THE DOOR INSTALLERS WILL DO

A MORE PRECISE ADJUSTMENT ON-SITE.

EVERY HEADER UNDERGOES EXTENSIVE COMPUTERIZED TESTING.

THIS CHECKS THE FUNCTION AND SAFETY FEATURES.

THEN, THE DOORFRAME AND STRUCTURE SHIP OUT

TO THE BUILDING SITE,

WHERE THE GLASS PANES GO IN PRIOR TO INSTALLATION.

Narrator: GIN IS A DISTILLED ALCOHOLIC SPIRIT.

IT'S FLAVORED PRIMARILY WITH JUNIPER BERRIES.

IN FACT, THE WORD "GIN" IS

BELIEVED TO COME FROM "JENEVER," THE DUTCH WORD FOR "JUNIPER."

IT'S THE BASE FOR MANY POPULAR MIXED DRINKS,

SUCH AS THE MARTINI, THE SINGAPORE SLING,

AND, OF COURSE, GIN AND TONIC.

THIS MICRODISTILLERY PRODUCES GIN IN SMALL BATCHES

USING A SLOWER DISTILLATION PROCESS.

THEY DON'T ADD ANY SWEETENERS,

ARTIFICIAL FLAVORING, OR COLORING.

AT THIS DISTILLERY, EVERYTHING IS DONE BY HAND,

STARTING WITH THE MAIN INGREDIENT, JUNIPER BERRIES.

THEN, SPICES ARE ADDED --

DRIED ANGELICA PLANT ROOTS...

CORIANDER SEEDS...

LEMON PEEL AND CARDAMOM.

ALL THESE INGREDIENTS GO INTO A 90-GALLON COPPER STILL.

A SPIRIT DISTILLED FROM FERMENTED GRAIN

IS ALREADY IN THE STILL.

IT'S COMPLETELY TASTELESS

BUT HAS AN ALCOHOL CONTENT OF 95%.

TO LOWER THE ALCOHOL LEVEL TO 40%,

THEY'VE DILUTED IT WITH SPRING WATER.

NOW THEY PREPARE TO REDISTILL WITH THE SPICES.

THIS GIVES THE SPIRIT ITS DISTINCT GIN FLAVOR.

TO DO THIS, THEY SLOWLY HEAT THE BOTTOM OF THE STILL.

IN ABOUT AN HOUR, THE ALCOHOL BOILS AND BEGINS TO EVAPORATE.

THEY CONTINUE DISTILLING FOR ABOUT SIX HOURS,

CONSTANTLY MONITORING THE TEMPERATURE.

IF THE TEMPERATURE REACHES 212 DEGREES,

THE WATER WILL ALSO EVAPORATE, RUINING THE BATCH.

THE ALCOHOL STEAM RISES UP AND OUT OF THE STILL

THROUGH PIPES LEADING TO A CHILLED STAINLESS STEEL TANK.

WHEN THE HOT STEAM HITS THE COLD,

IT CONDENSES BACK TO A LIQUID, CREATING GIN.

THROUGHOUT THE DISTILLATION PROCESS,

THEY TAKE SAMPLES TO MEASURE THE DENSITY AND TEMPERATURE.

THESE READINGS REFLECT THE CURRENT ALCOHOL LEVEL.

THEY ADJUST THE DISTILLATION SPEED AS REQUIRED

TO PRODUCE A TARGET ALCOHOL LEVEL OF 76%.

ONLY THE MIDDLE OF EACH BATCH,

KNOWN AS THE HEART OF THE DISTILLATION, IS COLLECTED.

THIS PARTICULAR DISTILLERY ADDS ANOTHER STEP.

THEY INFUSE THE GIN WITH RAW PARSNIPS.

THIS GIVES IT AN EARTHY FLAVOR AND SUBTLE FLORAL AROMA.

THEY PEEL AND SLICE THE PARSNIPS,

PLACE THEM IN A TANK, THEN PUMP IN THE GIN.

AFTER A COUPLE OF DAYS,

THEY PUMP IT THROUGH FILTERS ON THE WAY TO A STORAGE TANK.

THEN, THEY DILUTE THE GIN WITH WATER

TO LOWER THE ALCOHOL LEVEL TO 43%.

BEFORE BOTTLING, THE DISTILLERY DRAWS SAMPLES

FOR QUALITY CONTROL TESTING.

THEY EXAMINE THE COLOR, THE AROMA,

AND, OF COURSE, THE TASTE.

THERE WILL BE SLIGHT VARIATIONS IN FLAVOR

BASED ON THE FRESHNESS OF THE PARSNIPS.

THIS MICRODISTILLERY HAS NO AUTOMATED BOTTLING LINE.

THEY FILL THE BOTTLES BY HAND ONLY SIX AT A TIME.

THEY CORK EACH BOTTLE INDIVIDUALLY

WITH A HAND-OPERATED PRESS.

THEY APPLY A PLASTIC SLEEVE,

WHICH THEY HEAT-SHRINK TIGHTLY OVER THE NECK.

THE CONSUMER PULLS A SMALL GOLD TAB

TO REMOVE THE SEAL AND UNCORK THE BOTTLE.

THIS HAND-OPERATED MACHINE LABELS ONE BOTTLE AT A TIME.
