Beer Guide: Ales, Lagers, and Craft Beer Styles
Beer is the world’s most consumed alcoholic beverage and one of its oldest prepared foods. The variety of beer styles available today is staggering, from pale, crisp lagers to dark, roasty stouts, from hop-bomb IPAs to funky, sour lambics. Every style traces its lineage back to four essential ingredients: water, malted barley, hops, and yeast. Understanding how these ingredients interact and how different brewing techniques produce different styles gives you a framework for appreciating the full spectrum of beer. This guide covers the major beer families, the defining characteristics of popular styles, how to taste and evaluate beer, and how to pair beer with food.
The Four Ingredients
Water
Beer is more than ninety percent water, and the mineral composition of the water profoundly affects flavor. The famous pale ales of Burton-on-Trent owed their character to water high in calcium sulfate. The dark stouts of Dublin were built on soft water low in mineral content. Brewers today adjust their water chemistry to match the style they are brewing, adding minerals to replicate classic brewing regions or to highlight specific hop or malt characters.
Malt
Malted barley provides the fermentable sugars that yeast convert into alcohol and the color, body, and flavor of the finished beer. Lightly kilned malts produce pale, bready flavors suitable for lagers and pale ales. Darkly roasted malts contribute chocolate, coffee, and caramel notes to stouts and porters. The degree of roasting determines the beer’s color, measured on the Standard Reference Method scale, from the pale straw of a pilsner at two SRM to the opaque black of an imperial stout at forty-plus SRM.
Hops
Hops are the flowers of the Humulus lupulus plant and provide bitterness to balance the sweetness of malt, as well as aroma and flavor. Hops contain alpha acids that isomerize during boiling to produce bitterness. They also contain essential oils that contribute citrus, pine, floral, tropical fruit, and herbal aromas. The timing of hop additions determines their effect. Bittering hops added early in the boil contribute bitterness without aroma. Aroma hops added late in the boil or during fermentation contribute intense aromatic character without significant bitterness. Dry hopping, adding hops to the finished beer during conditioning, maximizes aromatic impact.
Yeast
Yeast is the microorganism that ferments the sugars in wort into alcohol and carbon dioxide. Different yeast strains produce radically different beer styles. Ale yeast ferments at warmer temperatures and produces esters and phenols that create fruity and spicy flavors. Lager yeast ferments at cooler temperatures and produces clean, crisp flavors. Wild yeast and bacteria produce the complex, funky, and sour flavors in spontaneously fermented beers such as lambics and Flanders red ales.
Ale Styles
Ales are fermented at warm temperatures with top-fermenting yeast strains. The category encompasses the widest range of flavors and styles.
Pale Ale
Pale ale is the foundational craft beer style. It balances moderate hop bitterness with a bready malt backbone. English pale ales are earthy and balanced, with flavors of biscuit, toffee, and floral hops. American pale ales are more assertive, using New World hop varieties that contribute citrus and pine aromas with a cleaner malt profile.
India Pale Ale
India Pale Ale, or IPA, is defined by pronounced hop bitterness and aroma. The style originated as a strongly hopped pale ale that could survive the sea voyage from England to India. Modern IPAs have evolved into a broad family. West Coast IPAs are bitter, dry, and intensely hoppy with resinous pine and citrus character. New England IPAs are hazy, juicy, and low in bitterness with intense tropical fruit hop flavors. Double and triple IPAs increase the malt and hop quantities for higher alcohol and more intense hop presence.
Stout and Porter
Stout and porter are dark beers that use roasted malts to produce chocolate, coffee, and caramel flavors. The difference between them is historical rather than technical; in modern usage, stout often indicates a stronger, more roasted beer than porter. Dry Irish stout, exemplified by Guinness, is light-bodied with a dry, roasted character and low carbonation. Imperial stout is a high-alcohol, full-bodied version with intense dark fruit, chocolate, and molasses flavors. Oatmeal stout uses oats to add body and a silky mouthfeel. Milk stout uses lactose, an unfermentable sugar, to add residual sweetness.
Belgian Ales
Belgian brewing traditions produce some of the world’s most distinctive ales. Belgian yeast strains create complex esters and phenols that produce flavors of banana, clove, bubblegum, and pepper. Dubbel is a mahogany-colored ale with flavors of dark fruit, chocolate, and caramel. Tripel is a golden, strong ale with spicy, fruity notes and a dry finish. Belgian golden strong ale is pale, highly carbonated, and deceptively potent. Saison, a farmhouse ale, is spicy, fruity, and highly carbonated with a dry finish.
Wheat Beer
Wheat beers substitute a significant proportion of wheat for barley malt, producing a lighter body and hazy appearance. German hefeweizen is cloudy, highly carbonated, and features banana and clove flavors from the yeast. Belgian witbier is spiced with coriander and orange peel, producing a refreshing, citrusy character. American wheat beer is clean and neutral, serving as a canvas for fruit additions.
Lager Styles
Lagers are fermented and conditioned at cold temperatures with bottom-fermenting yeast. The cold fermentation produces clean, crisp flavors without the fruity esters of ales.
Pale Lager
Pale lager is the world’s most popular beer style, encompassing American adjunct lagers, German helles, and Czech pilsner. The style is characterized by low bitterness, light body, high carbonation, and a clean, malty finish. Czech pilsner, the original pale lager, has a more pronounced hop bitterness and a golden color. German helles is maltier and softer. American adjunct lagers use rice or corn to lighten the body and produce a crisp, neutral flavor.
Dark Lager
Dark lagers use roasted malts to produce a dark color without the roasted bitterness of stout. German dunkel is malty, smooth, and bread-like with subtle chocolate notes. Schwarzbier, black beer, is a dark lager with a clean, roasted character and no harsh bitterness. Czech tmavé is a rich, full-bodied dark lager with caramel and dark fruit flavors.
Bock
Bock is a strong German lager with a malty, rich character. Traditional bock is amber to dark brown with flavors of toasted bread, caramel, and dark fruit. Doppelbock, or double bock, is stronger and maltier, often with a sweet, almost sweet finish. Eisbock is a concentrated version created by freezing the beer and removing ice, concentrating the alcohol and flavor.
Sour and Wild Beers
Sour beers are produced by introducing wild yeast and bacteria during fermentation. Lactobacillus produces a clean, tart sourness. Pediococcus produces a deeper, funkier sourness. Brettanomyces produces earthy, barnyard, and tropical fruit flavors.
Lambic
Lambic is a spontaneously fermented wheat beer from Belgium’s Senne Valley. It relies on wild yeast and bacteria present in the air of the region, which is impossible to replicate elsewhere. Gueuze is a blend of young and old lambics that undergoes a second fermentation in the bottle, producing a dry, tart, and highly carbonated beer. Fruit lambics, such as kriek (cherry) and framboise (raspberry), add fruit that balances the intense sourness.
Gose
Gose is a German sour ale brewed with salt and coriander. It is light-bodied, highly carbonated, and refreshingly tart, often with added fruit. The salt enhances the perception of refreshment and balances the acidity.
Flanders Red Ale
Flanders red ale is a sour, oak-aged ale from Belgium with a deep burgundy color and flavors of cherry, dark fruit, and vinegar. It is aged in oak barrels for up to two years, during which lactic acid bacteria and Brettanomyces develop the sour, complex character.
Tasting and Evaluating Beer
Beer tasting follows the same sensory discipline as wine tasting. Observe the appearance, noting the color, clarity, foam head, and carbonation. Smell the beer and identify malt, hop, yeast, and fermentation aromas. Taste and evaluate the balance between sweetness and bitterness, the body and mouthfeel, the carbonation level, and the finish. A great beer has balance, complexity, and a finish that makes you want another sip.
Food Pairing
Beer’s carbonation, bitterness, and acidity make it a versatile food partner. Pale lagers and pilsners cut through rich, fried foods and complement light seafood. IPAs stand up to spicy cuisines, their bitterness amplifying the heat. Stouts and porters pair beautifully with chocolate desserts and grilled meats. Sour beers cut through fatty fish and rich cheeses. Wheat beers complement salads and lighter fare.
Frequently Asked Questions
What is the difference between ale and lager?
The primary difference is the yeast strain and fermentation temperature. Ale yeast ferments at 60 to 75 degrees Fahrenheit and produces fruity, spicy esters. Lager yeast ferments at 45 to 55 degrees Fahrenheit and produces clean, crisp flavors. The result is that ales tend to be more complex and aromatic, while lagers are smoother and more refreshing.
Why does craft beer have higher alcohol content than mass-market beer?
Many craft styles deliberately aim for higher alcohol content, but this is a choice rather than a requirement. Imperial stouts, double IPAs, and barleywines are all high-alcohol styles. However, many craft lagers, session IPAs, and mild ales have moderate or low alcohol content. The alcohol level is determined by the style and the brewer’s intent, not by the category of craft versus mass-market.
How should I store beer?
Store beer upright in a cool, dark place. Temperature fluctuations and light, especially ultraviolet light, degrade hop compounds and produce a skunky aroma. Most beers are best consumed within three to six months of packaging. Strong, high-alcohol beers can age for years and develop complex flavors similar to fine wine.
What does a skunky smell in beer mean?
A skunky, sulfurous aroma indicates that the beer has been exposed to ultraviolet light, which breaks down hop compounds into a compound nearly identical to a skunk’s defensive spray. Brown glass bottles offer some protection, but clear and green glass bottles offer little. Avoid beer displayed in clear bottles in direct sunlight.
Can I pair beer with wine or cocktail courses at the same meal?
Absolutely. Beer’s versatility makes it an excellent partner for multi-course meals. A light pilsner with appetizers, a Belgian tripel with seafood, a stout with the main course, and a fruit lambic with dessert creates a progression that rivals any wine pairing. The carbonation in beer also acts as a palate cleanser between bites.
Conclusion
The world of beer offers extraordinary range and complexity. From the crisp refreshment of a Czech pilsner to the deep, roasty intensity of an imperial stout, there is a beer style for every palate, every food, and every occasion. Understanding the roles of malt, hops, yeast, and water, and how different fermentation techniques produce different families of beer, gives you the tools to explore with confidence. Taste broadly, pay attention to what you enjoy, and let your curiosity guide you through the remarkable diversity that brewers around the world have created.
