BEER CHAT
FROM THE
Last e-news
we mentioned how winemaking is straightforward: squeeze the grapes, ferment the
juice. Good grapes and no errors
generally results in good wine.
Beermaking
requires more skill and more decisions: barley is first malted, then milled, then mashed. Then the liquid is gently rinsed away from
the husks, boiled and seasoned with hops (in all their wondrous variety!) At last comes cooling, fermentation, and
conditioning: all these steps require decisions and result in different flavors
. . . and we haven’t even mentioned specialty grains yet.
Beer is
made from water and malted barley of some kind – pale malt, pilsner malt,
six-row. These sprouted barleycorns are
packed with starch and with natural enzymes that will turn the starch into
sugar; the sugar will eventually fuel the yeast later, during fermentation. (Craft beer gets its fermentable sugar from
barley, wheat or rye; some specialty craft brewers also add fruit, honey or
Belgian candi sugar. American light lagers use a percentage of rice or corn in
addition to barley.)
To add
darker colors or roasty flavors, or caramel flavors, or biscuity flavors, or
smoky flavors, or to change the body and mouthfeel of a beer, brewers often add
some malt that has been handled differently from the base malt. Often it has been heated, either under dry or
wet conditions, and it is no longer “enzymatically active” – that means it will
not convert from starch to sugar, and fuel the yeast. It’s there in the recipe only for flavor,
body and color, and usually makes up less than 10% of the total malt bill.
Here are some
varieties of specialty grains and what they do for flavor & color:
-Crystal
Malt: pale malt is heated while wet, and the starch turns to sugar and then
caramelizes, all within the barleycorn.
-Chocolate
Malt: no chocolate here – this is malt that has been roasted dry, in a drum
like coffee, until it is a deep brown color.
Used in porters, brown ales, and sometimes in other dark beers to give
round, deep flavor notes that sometimes stop at nutty and don’t reach
roasty. Also used in small amounts in
amber ales and even some pale ales.
-Black
patent malt/roasted (unmalted) barley: Malted (or sometimes unmalted) barley roasted
until black and charred. In judicious
amounts gives roasty flavor and dark color; in heavier amounts makes for opaque
black beer and sharply roasted flavors.
-Peated, or
Distiller’s Malt: Malt kilned over a peat fire, leading to the smoky, spicy
flavor found in some Scotch ales, and some American craft beers. Used by distillers of Scotch whisky in their
mash.
-Smoked
Malt: Malt smoked over wood. In
There are
many varieties and versions of specialty grains; there are even malts kilned at
higher temperatures (like
