Have you ever sat at a bar, stared at a sea of tap handles, and wondered: “Why do all lagers taste the same?” This is a common question that even seasoned beer enthusiasts grapple with. Contrary to popular belief, lagers do not all taste the same. The consistency in taste is often attributed to the specific brewing process and ingredients that give lagers their distinctively crisp, clean profile. Yet, there’s more diversity within the realm of lager than meets the eye, with subtle variations awaiting the discerning palate
The Lager Lowdown: Decoding the Similarity
From the bustling beer halls of Munich to the neighbourhood pubs of London, lagers are a global favourite. But what gives them their hallmark taste, and why do they often seem so similar?
The crux of the lager puzzle lies in its unique brewing process. Unlike ales brewed with top-fermenting yeast at warmer temperatures, lagers utilise a bottom-fermenting yeast strain known as Saccharomyces pastorianus. This yeast does its magic at cooler temperatures, generally around 7-13°C, a process aptly termed “lagering” from the German word “lagern” – to store.
Lagering encourages the yeast to produce fewer fruity esters and spicy phenols – flavour compounds commonly found in ales. Instead, the lager’s flavour profile tends to be clean and crisp, allowing the malt and hops to take centre stage. This characteristic taste, subtle and less varied than the broad spectrum of ales, contributes to the perception of lagers as being remarkably alike.
Moreover, the traditional lagering process involves an extended maturation period at near-freezing temperatures, often weeks to months. This step helps to smooth out any rough edges in the flavour and produces a rounded, well-balanced beer. This consistency in the process leads to consistency in taste.
However, it’s essential to note that not all lagers are identical. Variations in the type of malt and hops used, the specific strain of lager yeast, and local water quality can all impact the final product, leading to subtle differences in flavour, aroma, and mouthfeel. Hence, while lagers might share certain taste elements, each brew is unique in its own right. So, what then separates a premium lager from a regular lager? Is it all in the name, or does the difference lie deeper?
Not All Lagers are Created Equal: Premium Lager vs Lager
You’ve undoubtedly noticed the term ‘premium lager’ emblazoned on some beer labels, while others simply state ‘lager’. Is there a significant difference between these two, or is it merely clever marketing?
Firstly, it’s essential to understand that there’s no standard, regulated definition for ‘premium’ in the beer industry, unlike terms like ‘organic’ or ‘gluten-free’. Therefore, ‘premium’ often refers more to a brewery’s positioning of its product than to specific brewing characteristics.
However, many premium lagers often possess specific distinguishing characteristics. They tend to incorporate top-quality ingredients such as speciality malts and exclusive hop varieties. They may employ traditional brewing methods, such as lengthier lagering periods, to enhance the beer’s smoothness and balance. As a result, these lagers can provide greater complexity and depth of flavour compared to their standard counterparts.
Nonetheless, be aware that not all ‘premium’ labels deliver on this promise. Some breweries might label their lagers as ‘premium’ as part of their marketing strategy, even if the beer doesn’t significantly differ from standard lagers in quality or taste.
Another element in the premium vs regular lager debate is the alcohol content. Some people associate premium lagers with a higher ABV, but this isn’t a universal rule. It’s perfectly possible to find low-ABV beers that are considered premium due to their exceptional quality and flavour.
Ultimately, the distinction between premium and standard lager lies mostly in your personal taste preferences. How can you discern the difference? The answer lies in a good old taste test. But what if you’ve had your fill of store-bought lagers and fancy trying your hand at brewing your own at home?
DIY Brewing: Can You Make Lager at Home?
Indeed, you can brew lager at home, and it can make for an exciting journey for any beer enthusiast. However, it’s worth noting that brewing lager requires a bit more patience and precision than brewing ale, primarily because of the lagering process.
Lager yeast, a bottom-fermenting variety, thrives at cooler temperatures, typically between 7-13°C. This cooler fermentation process gives lagers their signature clean, crisp flavours but also necessitates a longer fermentation period.
Compared to the few days needed for ales, a typical lagering period can last several weeks or even months. This time allows any remaining sugars to be fully consumed, reducing unwanted flavours and aromas, leading to a smoother, more balanced beer.
If you’re considering brewing your own lager, you’ll need to think about your equipment. For lagers, you may need a dedicated fridge or a cool cellar to consistently maintain the required cool temperatures, in addition to the regular brewing gear.
Homebrew shops often offer lager kits, which include malt extract, lager yeast, and hops. You can also purchase these ingredients separately if you prefer a customised brew. Remember, balance is key in lager brewing due to its subtle flavour profile.
Summary
Despite their seemingly common, crisp, clean taste, lagers hold a world of subtly distinct flavours and characteristics. This perceived uniformity in lagers can be traced back to their specific brewing process, using a particular lager yeast and lower temperatures, leading to a cleaner, less fruity profile than ales. However, not all lagers are created equally. Premium lagers often utilise high-quality ingredients and more time in the brewing process, resulting in more refined flavours and a smoother finish. If you’re an adventurous beer enthusiast, brewing lager at home is a perfectly viable and exciting endeavour. Although it requires patience due to the cooler fermentation and extended lagering periods, the result can be rewarding. With this newfound knowledge, your next sip of lager might reveal a fresh appreciation for this classic beer style. So, remember, even though lagers might share certain characteristics, they are far from being all the same.
