PEARLS

​

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.

​

Caffeine content?

 

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.

How does

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

with distilled,

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.

Storage

 

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.
