Essential Ingredients of Beer

• Malted Barley• Hops• Yeast• Water• Not required, but

frequently found ingredient– Starch adjuncts

• Corn and rice starches

Making Beer:a three step process

• Malting• Brewing• Fermentation

Malting• Takes place in malt houses– Occasionally in a brewery (Coors)

• Controlled germination of barley– Moisture – Temperature– Carbon dioxide

• Goal– Produce enzymes useful for brewing

• Amylases• proteases

Malting• Soaking the grain• Allow for controlled

germination– Maximum enzyme

production– Minimum enzymatic

activity and plant growth• Kiln drying– Stop germination – Stabilize malted barley– Impart color and flavor

• Light malt, dark malt, amber malt, black patent malt

Brewing

• Brewing done in 5 steps:–Milling–Mashing– Lautering–Wort boiling–Whirlpool kettle–Wort cool

Brewing

• Milling of malted barley– Careful cracking of malted barley• Shatter endosperm• Keep husk in large pieces

• Adding water• Controlled temperature for enzymatic action

Mash Tun

The mash tun is a vessel in which the milled malted barley is mixed with waterAnd the enzymes are allowed to degrade the starches and proteins intoSubstrates that the yeast can utilize during fermentation

Mash

These photos show the milledMalted barley being mixed withWarm water. The enzymes Convert the starch to maltose and The proteins to amino acids creatingWhat is known as sweet wort.

Lautering (filtering)The sweet wortIs separated from The spent barleyBy a filtration stepKnown as Lautering. The Barley husks serveAs the primaryFiltering material.Here, the remainingSpent grains areBeing removed fromThe sweet wortWith this screen.

Wort boiling

Extraction of hops and pasteurization of wort and colourization is the main principle of boiling.

Whirlpool Kettle

Operation:

• To rest the wort in whirlpool

Fermentation and cellar

Fermentation:

• It is the process of production of alcohol and release the co2 from the malt sugar by action of yeast cells

Unitanks:

Beer filtration

• Beer filtration is a separation process in which the yeast cells and other turbidity causing materials steel present in beer are removed from the beer

• By using plate and frame filter
