Explore The Nuances: 3A Draft Beer Vs Pilsner

Beer is one of the most widely consumed alcoholic beverages in the world, with over 9,000 craft breweries in the US alone. There are two main categories of beer: ales and lagers. Ales are brewed at warmer temperatures than lagers, with top-fermenting yeast, and have a more complex flavour profile. Lagers are known for their crisp, clean taste and are typically brewed at cooler temperatures, using bottom-fermenting yeast. Pilsners, which originate from the Czech Republic, fall under the lager category. German pilsners have a pale gold colour and a crisp flavour, while Czech pilsners are darker and more bitter. Draft beer, also known as draught beer, is typically served from a keg or cask and consumed at bars and restaurants.

Pilsner is a type of lager beer, produced through a specific process of lagering

Pilsner, also known as pilsener or simply pils, is a type of lager beer. It takes its name from the city of Pilsen (Plzeň in Czech) in the historical region of Bohemia, which is now part of the Czech Republic. The world's first pilsner, Pilsner Urquell, was produced in 1842 by the Pilsner Urquell Brewery.

Pilsner is a pale lager with a crisp, refreshing taste that's lightly hopped. It is bottom-fermented, which means the yeast settles at the bottom rather than floating at the top, as is the case with ales. Pilsner is brewed with pilsner malt, lightly kilned malted barley, lager yeast, spicy hops, and soft water. The head of a pilsner is typically white and dense, and the body is straw-coloured. The aroma features hints of hops and graininess, and the flavour is simple, with light grain and hops bittering.

The process of making pilsner involves carefully controlled "lagering". This is an aspect of the beer brewing process that can produce other types of lagers under different circumstances. Therefore, all pilsners are lagers, but not all lagers are pilsners. The specific process of lagering involves storing the beer at cold temperatures for months before it is ready to be consumed. This is where the term "lager" comes from, as it is derived from the German word "lagern", which means "to store".

Pilsner is the most popular style of beer in the world, commanding over half of the beer market worldwide. It is brewed all over the world, with different regions having their own variations, such as German-style pilsner, European-style pilsner, Mexican-style pilsner, American-style pilsner, and Australian-style pilsner.

Lager is bottom-fermented with yeast settling at the bottom, while ale has yeast floating at the top

Lager and ale are two of the main types of beer. The key difference between the two is that lager is bottom-fermented, while ale is top-fermented. This means that during the fermentation process, the yeast used in lager settles at the bottom of the wort, whereas the yeast in ale floats at the top.

Lager yeast works at the bottom of the wort at a much lower temperature, typically between 4°C and 10°C. This is because lager yeast is a hybrid of Saccharomyces cerevisiae and Saccharomyces eubayanus, a wild yeast from Patagonia that can thrive in colder temperatures. The baby yeast, or the offspring of these two yeast types, Saccharomyces pastorianus, inherited this ability to thrive in cold temperatures. The slower metabolism of lager yeast means that bottom-fermenting lagers take longer to ferment, resulting in a "crisper" beer with less pronounced flavours compared to ale.

Ale yeast, on the other hand, is applied to the top of the wort and ferments at a higher temperature, typically between 17°C and 25°C. This top-fermenting method is the oldest method of brewing beer, and the yeast used for it is called Saccharomyces cerevisiae. Top-fermenting tends to yield more flavour due to the warmer fermentation temperature, as esters and phenols are more pronounced.

It is important to note that the terms "bottom-fermenting" and "top-fermenting" are somewhat misleading, as during active fermentation, yeast can be found throughout the wort, regardless of the type of beer being brewed. However, the terms originated from the practices of top and bottom cropping, where yeast was harvested from the top or bottom of the fermenter, respectively. Over time, these practices led to the selection of yeast that preferred to live at the bottom or top of the wort, resulting in the distinction between lager and ale yeast.

Now, to clarify the difference between draft beer and pilsner: draft beer, or draught beer, refers to beer that is stored and served from large kegs or casks. It can be either lager or ale, and it is not pasteurised, which means it must be kept at low temperatures at all times. Pilsner, on the other hand, is a specific type of lager that is carefully controlled and produced through a process called "lagering". Therefore, all pilsners are lagers, but not all lagers are pilsners.

Draught beer is stored and served from large kegs and casks, not a type of beer

It is a common misconception that draught beer is a special type of beer. However, draught beer is simply beer that is stored and served from large kegs and casks. The word “draught” refers to beer that is kept in large containers called casks with a capacity of 5 gallons or more. The term "draft" reflects the historical practice of pulling a hand pump to dispense ale beer from these large casks in ancient times.

It is important to note that draught beer is not a specific type of beer but rather a method of storage and serving. Any style of beer, such as lager or ale, can be served as draught beer. Lager and ale are the two main types of beer, differentiated by the fermentation process and the behaviour of yeast during fermentation. Lager is bottom-fermented, with yeast settling at the bottom, while ale has yeast floating at the top. Additionally, lager requires cold temperatures for fermentation and takes months to be ready for consumption.

Pilsner, on the other hand, is a specific type of lager. It is the result of carefully controlled "lagering," a process in brewing that can produce various types of lagers. Pilsners are characterised by their golden colour and crisp, clean taste. Therefore, when comparing a pilsner and draught beer, it is essential to understand that they are different in nature. A pilsner is a specific variety of lager, while draught refers to the serving method of any beer from a keg or cask.

To summarise, draught beer is not a distinct type of beer but a term used to describe the storage and serving method of any beer, including lager and ale, from large kegs or casks. Pilsner, being a type of lager, can also be served as draught beer. The key distinction lies in the fact that draught refers to the method of serving, while pilsner identifies a specific style or variety of lager beer.

Draft beer is served only in pubs, while bottled/canned lager can be consumed anywhere

There are several differences between draft beer and bottled or canned lager. Firstly, draft beer is stored and served from large kegs and casks, typically in pubs and other similar establishments, whereas lager is available in cans and bottles and can be consumed anywhere. This is a key distinction between the two types of beer.

Draft beer is not pasteurised, whereas lager is pasteurised before bottling or canning. This means that draft beer must be kept at low temperatures at all times to prevent spoilage, whereas lager does not have the same temperature requirements. In addition, draft beer tends to foam more than lager, and it is also generally less expensive.

The flavour of draft beer can be influenced by various factors, including the cleanliness of the lines and glassware, refrigerator temperatures, and serving gas pressure. These variables may cause the beer to taste "off". Therefore, the flavour of draft beer can vary depending on the establishment serving it. On the other hand, lager beer is less susceptible to flavour changes, as it is packaged in bottles or cans that protect the beer from light and oxygen exposure, which can compromise the flavour.

It is worth noting that the terms "draft" and "lager" do not refer to specific types of beer. Lager refers to beers that are bottom-fermented with yeast settling at the bottom, and it requires cold temperatures for fermentation. Pilsner is a type of lager, produced through a carefully controlled lagering process. All pilsners are lagers, but not all lagers are pilsners.

Lager is pasteurised, while draft beer is not, and must be kept at low temperatures

Lager is a type of beer that undergoes a unique process called "lagering", which involves storing the beer at a cold temperature for an extended period. This process, also known as "cold-conditioning", helps to smooth out the beer's flavour and clarify the beverage. Lagering can last for weeks or even months, and during this time, the yeast and other particles in the beer settle, resulting in a clear and crisp drink. The name "lager" itself comes from the German word "lagern", which means "to store" or "warehouse", reflecting this crucial step in its production.

On the other hand, draft beer, also known as "draught beer", is unpasteurised and must be kept at low temperatures to stay fresh. Pasteurisation is a heat treatment process that kills bacteria and extends the shelf life of beverages like beer. However, draft beer skips this step, and instead, the fresh, unprocessed brew is delivered directly from the brewery and served from a keg. This means that draft beer has a shorter shelf life and must be consumed within a shorter period, typically a few weeks, to ensure optimal flavour and quality.

The difference in pasteurisation between lagers and draft beers leads to distinct flavour profiles and characteristics. Lager, due to its pasteurisation, tends to have a more consistent and stable flavour, and its longer shelf life makes it widely available and convenient for distribution and storage. The cold-conditioning process contributes to a clean, crisp taste that has made lagers one of the most popular beer styles worldwide. Lagers are often considered smooth and easy to drink, with a subtle, refined character.

In contrast, draft beer is prized for its fresh, vibrant flavour. Without pasteurisation, the beer retains more of the subtle nuances of the ingredients, resulting in a more complex and dynamic taste experience. The flavour of draft beer is often described as "alive" or "brighter" compared to pasteurised beers. The lack of heat treatment also means that more vitamins, minerals, and antioxidants are preserved in draft beer, contributing to its unique character and potential health benefits.

The serving temperature also plays a crucial role in the drinking experience of lagers and draft beers. Lager is typically served chilled, and its smooth, crisp character is accentuated by the cool temperature. The cold temperature helps to refresh the drinker and enhance the beer's carbonation, creating a light and effervescent mouthfeel. Draft beer, however, is ideally served slightly warmer than lager, usually just a few degrees above freezing. This slightly warmer temperature range allows the flavours and aromas of the draft beer to fully express themselves, providing a more robust and nuanced sensory experience.

Additionally, the carbonation levels between lagers and draft beers can vary. Lager is often heavily carbonated, contributing to its refreshing quality and the formation of a frothy head when poured. On the other hand, draft beer may have a slightly lower carbonation level, creating a smoother, less bubbly mouthfeel. This subtle difference in carbonation can impact the drinker's perception of the beer's body and texture, adding another layer of distinction between the two styles. In summary, the pasteurisation and temperature requirements of lagers and draft beers are key factors in shaping their distinct characteristics, flavour profiles, and sensory experiences they offer to beer enthusiasts.
