Many persons restrict the term beverages, contending that it refers
to refreshing or flavored drinks. It should be remembered, however, that
this term has a broader meaning and refers to any drink taken for the
purpose of quenching thirst. Water is the simplest beverage and is in
reality the foundation of nearly all drinks, for it is the water in them
that slakes thirst. Flavors, such as fruit juice, tea, coffee, etc., are
combined with water to make the beverages more tempting, and
occasionally such foods as eggs, cream, and starchy materials are added
to give food value; but the first and foremost purpose of all beverages
is to introduce water into the system and thus satisfy thirst.
5. KINDS OF WATER.--Inasmuch as water is so important an element in the
composition of beverages, every one should endeavor to become familiar
with the nature of each of its varieties.
SOFT WATER is water that contains very little mineral matter. A common
example of soft water is rainwater.
HARD WATER is water that contains a large quantity of lime in solution.
Boiling such water precipitates, or separates, some of the lime and
consequently softens the water.
