About Caldera:
• We put together ‘Cal’, which comes from Calcutta’s old and
evergreen name and ‘dera’ a synonym of Kolkata’s old age
adda culture which is prevalent throughout the city, to come
up with the name Caldera. Inspired by the city’s relaxed,
chill-paced lifestyle , Caldera is an ode to its people – the
happiest people of the lot! The name Caldera is our way to
pay a tribute to the ‘Cal way of life’.
• We take great pride in mentioning Kolkata’s finest craft in our
logo’s tagline as the brand is well-knit to the city’s culture to
appreciate crafts of all sorts.
• As big an emotion the city is the people are the one who
adds the ‘joy’ to the ‘city of joy’. Often synonymous with the
city of love, the nooks and corners of the city whisper stories
of mischief and timeless love. Standing on the crossroads of
love and joy, the city deserves its own celebratory drink -
their own craft.
• That’s how the idea of brewing our own craft came up. We
decided to brew the happiest/hoppiest craft for these
people. For people who are in love with the ‘happy state of
mind’, Caldera, Kolkata’s finest craft, is the drink for them!
What is Beer?
Beer is an alcoholic beverage that has been consumed
for thousands of years. It is typically made from water,
malted barley, hops, and yeast. The brewing process
involves fermenting sugars, often derived from malted
barley, with yeast, which produces alcohol and
carbonation. There are various styles and types of beer,
each with distinct flavors and characteristics. Beer is a
widely enjoyed and culturally significant beverage
worldwide, often served in social settings or paired with
food.
MALT WATER
KEY INGREDIENTS
OF BEER MAKING
YEAST HOPS
MALT
Malt is a key ingredient in the production of beer. It is germinated
cereal grains, usually barley, that have been dried through a
process known as malting. Malting involves soaking the grains in
water to allow them to germinate and then drying them with hot air.
This process activates enzymes in the grains, converting the starches
into fermentable sugars.
In brewing, malt provides the sugars needed for fermentation by
yeast, which in turn produces alcohol and carbonation.
Additionally, malt contributes to the flavor, color, and aroma of the
beer. Different types of malt, such as pale malt, caramel malt, and
chocolate malt, offer varying degrees of sweetness, color, and
other characteristics to the final beer.
Malt plays a crucial role in defining the overall profile and style of a
beer, and brewers often select specific malts to achieve desired
outcomes in terms of taste, color, and mouthfeel.
WATER
Water is a vital ingredient in the brewing process, serving
various functions. It facilitates mashing, extracting sugars and
flavors from malt, and rinsing spent grains during lautering.
Water is crucial in boiling with hops, affecting beer bitterness.
It also aids in cooling the wort before fermentation and may
be used for dilution. Water quality, including minerals,
influences beer taste. Additionally, water is essential for
cleaning and sanitizing brewing equipment to maintain beer
quality. Overall, water plays a fundamental role in shaping
the taste, body, and characteristics of the final beer.
YEAST
Yeast is a single-celled fungus belonging to the biological kingdom
Fungi. In the context of beer making, the most common yeast used is
Saccharomyces cerevisiae for ales and Saccharomyces pastorianus
for lagers. Yeast plays a crucial role in fermentation, converting sugars
into alcohol and carbon dioxide, thus defining the alcoholic content
and carbonation of the beer. Additionally, yeast contributes to the
flavor and aroma of the final product.

Top-fermenting yeast refers to strains of yeast, Bottom-fermenting yeast refers to strains of yeast,
typically Saccharomyces cerevisiae, that ferment at specifically Saccharomyces pastorianus, that

with bottom-fermenting yeast.
HOPS
Hops are cone-shaped flowers of the hop plant essential
in brewing beer. They contribute bitterness, balancing
malt sweetness, and provide a diverse range of flavors
and aromas, such as floral, citrus, pine, spice, and fruit.
Hops are added during the boil for bitterness and later in
the process for flavor and aroma, with dry hopping being
a common technique. Certain hop varieties have dual
purposes for both bittering and aroma. Hops also
historically served as a preservative, inhibiting microbial
growth and extending beer shelf life. The careful
selection of hop varieties allows brewers to create a wide
array of beer styles with unique sensory profiles.
