In medicine, "pearls" are small bits of free standing, practically useful information, often based on experience or observation rather than from academic studies.
Highly valued by clinicians, pearls can be used for decision making during daily life in the real world.
We thought we would apply this concept to coffee and offer a section of "coffee pearls", small bits of information and interesting facts we've learned about coffee.
Contrary to popular opinion,
the caffeine content in brewed coffee is
inversely proportional to the duration of roast
--- in other words ---
the darker the roast, the less caffeine
is in your cup.
For this reason, some prefer a medium
roast for their morning pickup
and a darker roast later
in the day.
the roast affect flavor?
Typically, the lighter the roast, the more
local nuance in the taste... there will be more
fruit or floral elements, and a smoother experience.
As the roast darkens, acidity and local features diminishes and bitterness increases.
Many people like dark, bitter coffee, but there will be less variation between dark coffees from different origins, as long as high quality is maintained.
Full City, which is between medium and
dark roasts, has elements of dark
bitterness while retaining some acidity
and local identity.
You may have noticed that
bags of Dark Roast seem fuller than Medium or Full City. This is because the beans actually lose a significant amount of weight as the roast progresses. Dark roast coffee will have more volume for the same weight, and the bag will be fuller.
Experts agree that the
flavor of coffee depends on
the water source and that the
best reliable way to ensure
excellent taste is to brew
not tap water.
Whatever method of brewing you use, be careful not to burn your coffee. Optimally, water should be about 95˚C when it contacts the coffee to begin brewing.
To maintain freshness,
keep coffee beans in dark and airtight location. Freezing beans is unnecessary, and coffee in your freezer can pick up unwanted taste from other items stored there.
Grind only the quantity of beans you will need just before brewing as ground coffee may start to become stale after fifteen minutes.
