Water Water is 90% of Beer Breaks down malts and exposes
starches and sugar
Slide 5
Hops Humulus Lupulus (hops) are the flowering cone of a
perennial vining plant and a cousin of the cannabis variety (sorry
no THC in this stuff) that typically thrives in climates similar to
the ones that grapes do. Hop plants are dioecious, meaning the
males and females flower on separate plants -- and the female cones
are used in the brewing process. Hops are the age old seasoning of
the beer, the liquid gargoyles who ward-off spoilage from wild
bacteria and bringers of balance to sweet malts. They also lend a
hand in head retention, help to clear beer (acting as a natural
filter) and please the palate by imparting their unique characters
and flavours. Basically, hops put the "bitter" in beer.
Slide 6
Malts/Adjuncts Malts/Adjucts provide the fermentable sugars
that are required to make beer (and to make beer "sweet"). The
process of malting converts insoluble starch to soluble starch,
reduces complex proteins, generates nutrients for yeast
development, and develops enzymes.
Slide 7
Extras Other ingredients that add flavor and/or fermentable
sugars that do not come from malt
Slide 8
Yeast Single celled organisms that are responsible for
converting starch and sugar into alcohol and CO2
Slide 9
Ale Yeast vs. Lager Yeast Ale Yeast Top Fermenting (yeast
ferments at the top) Ferment at Higher Temps Adds Fruity/Ester
Flavors Lager Yeast Bottom Fermenting (yeast ferments at bottom)
Ferment at Lower Temps Adds Crisp Clean Flavors
