THE FIELD GUIDE VOL. X
Beer is not sipped neat or shaken into cocktails, so filter it the way brewers actually classify it: by fermentation family and grain bill.
THE FIELD BOARD
Beer Styles Explained
Bottom Fermented • Cold Conditioned
Lager yeast works cool and slow, leaving a clean beer where malt and hop bitterness have nowhere to hide.
Top Fermented • Balanced
Warm-fermented ale yeast adds fruity esters, sitting between malt sweetness and hop bitterness.
India Pale Ale • Hop Forward
Heavily hopped ale, historically brewed strong and bitter for export. Modern hazy versions push aroma over bitterness.
Bavaria & Belgium • Cloudy
Brewed with a large proportion of wheat. German hefeweizen yeast gives banana and clove, Belgian witbier adds coriander and orange peel.
Roasted Barley • Dark
Roasted grain drives the colour and the coffee bitterness. Nitrogen dispense creates the dense creamy head of an Irish dry stout.
London Origin • Dark Malt
The older dark London style from which stout grew. Generally softer and more chocolatey than a roasty dry stout.
Belgium • Bottle Conditioned
Only beer brewed within the walls of a Trappist monastery under monastic control may carry the Authentic Trappist Product mark.
Wild Fermentation • Belgium
Lambic ferments spontaneously with wild yeast and bacteria. Gueuze blends young and old lambic to referment in bottle.
Germany • Strong Malty Lagers
Malt-driven lagers brewed for the seasons: Märzen for Oktoberfest, doppelbock originally brewed by monks for fasting periods.

Myth vs Fact
MythDark beer is always heavy and high in alcohol.
FactColour comes from roasted malt, not strength. A dry stout is often lighter in alcohol and calories than a pale double IPA.
Did You Know
The Bavarian purity law of 1516 allowed only water, barley and hops. Yeast was left out simply because nobody yet knew it existed; its role in fermentation was only identified centuries later.
Behind the Bar
Serving too cold flattens aroma. Keep crisp lagers near 5 °C, but let ales, stouts and Belgian strong beers come up to cellar temperature before pouring, and always use a clean, unfrozen glass.
