影音簡介 ：
Gregg Wallace is in Derbyshire at an enormous coffee
factory where they produce 175,000 jars of instant coffee
every day. He follows the production of freeze-dried instant
coffee, from the arrival of 27 tonnes of Brazilian green
coffee beans right through to dispatch. Along the way he
chills out in a freezer cooled to -46 degrees Celsius and
discovers how they give you that hit of freshly brewed
coffee smell when you pierce the foil lid. They extract the
aroma and put it back in just before the instant coffee
granules head into the jars.
Meanwhile, Cherry Healey learns about the chemistry of
coffee. She finds that roasting alters its chemical
composition, and listens for the 'first crack'as steam
splits the bean along its seam. She also goes cold turkey
on caffeine, giving up her coffee habit for five days to
understand how this most commonly used psychoactive drug
affects her body and brain. She discovers that the caffeine
withdrawal headache is due to increased blood flow to the
brain. And she is at Kew Gardens, where they have concerning
evidence revealing that climate change is affecting coffee
harvests worldwide. Cherry samples a brew made from the beans
of a coffee species that could cope in these warmer growing
conditions, and which could ensure a future for the daily
cuppa.
Historian Ruth Goodman investigates the origins of
instant coffee. She tastes a version that looks very like
axle grease which was drunk during the American Civil War
in the 1860s, and finds out why it began being reffered to
as 'a cup of Joe'. She also visits the site of the UK's
very first coffee house, which sprang up in a London
churchyard in 1652, and learns that the early passion
for coffee led to the founding of modern institutions,
including the Stock Exchange, auction houses and newspapers.
