[Homework]2014-11-03 啤酒是如何酿成的—9

it's not hard to spot a hop field, they are pretty distinctive, because the plant aregrown in rows on strings,
what I am doing there is breaking down the glands, the lupulin glands,  to release the resins.
inside the bracket layer of a female hop cones are wax coated lupulin glands,  they
house a yellow pollen which is made up a bitter resins and aromatic oils, combined , these give hops their bitter flavor  when they are tossed into  a steaming brewing kettle and boil
the bitter compounds, the resins, also have other influences, and they help stablize
the foam, they are also anti-microbial, so they are important for preventing
bacteria  from growing in the beer .
after malt is added to warm water, the beer begins to brew, the mixture taste
very sweet, but it's exactly when brewers add hops to balance the sweet taste
with a litter bitterness and create a more harmonious flavor, like most brewers, Anheuser-Busch uses a form of crushed or dried hops,
you see, we are in hop room now, these are hop pellets, you can see gree??
now what hop look likes when we use it.
the Sierre Novada brewery produces 750 barrels per year,
since we really focus and feature hops  in our beer, hops really are most critical
ingredient for us,
in fact, they grow three acres their own hops,
we have been growing our own hops here to brew for the last four years
