The Rich History of Belgian Beer
​
Belgian beer has a complex history that dates back to the medieval era where monks honed brewing , a tradition that continues to impact beer making today. During the Middle Ages, beer became a staple as water sources were often unsafe, making it a more reliable option. Monks were the main brewers, benefiting from their access to pure water and expertise in fermentation.
Trappist and Abbey beers played a crucial role in forming the Belgian brewing culture, which evolved under various laws and regulations, including a tax known as “gruit” instituted by the Catholic Church in 12th century. Over the years, the brewing landscape transformed, leading to beers that were both longer-lasting and more flavorful. By the 20th century, Belgian beer achieved international acclaim, particularly with the popularity of Trappist beers.
In 2016, UNESCO recognized Belgium’s brewing heritage as part of its Intangible Cultural Heritage. Today, Belgium boasts 6 Trappist breweries, each dedicated to producing exceptional beers. The quality of Belgian brewing has significantly influenced contemporary beer.
Belgian Pale Ale
Belgian Pale Ales strive for balance, typically featuring a modest ABV and subdued flavors of bubblegum, clove, and banana found in other styles. They often consist of a high proportion of Pilsner malt, with Munich or Vienna malt added for body and maltiness. Sugar, which is significant in Belgian brewing, is generally unnecessary due to the lower ABV, and hops play a balancing role rather than a dominant one.
​
Belgian Strong Pale Ale
These ales share a similar color to regular pale ales, ranging from gold to light copper. While hop bitterness remains balanced, what distinguishes strong pale ales is their higher alcohol content, which contributes spiciness and complexity to the beer. *
Trappist & Abbey Beer
Trappist beers are crafted by Cistercian monks and must be produced in one of the seven Trappist abbeys, six of which are in Belgium. These beers showcase a wide range of colors from pale to dark chocolate, typically categorized into Singel, Dubbel, Tripel and Quadrupel based on strength, often indicated by color. Hops are not prominent, and while may be included, they are used sparingly, resulting in a generally dry finish.
Lambic
Lambics are a type of beer brewed in the Pajottenland region of Belgium southwest of Brussels since the 13th century. Types of lambic beer include gueuze, kriek lambic, and framboise. Lambic differs from most other beers in that it is fermented through exposure to wild yeasts and bacteria native to the Zenne valley, as opposed to exposure to carefully cultivated strains of brewer's yeast. This process gives the beer its distinctive flavour: dry, vinous, and cidery, often with a tart aftertaste.
​
Saison
Saison is a farmhouse beer traditionally brewed for summer consumption. Generally moderate in strength, it features a significant amount of Pilsner malt along with aromatic malts. The hop profile is noticeable yet not overpowering, often using varieties like Saaz, and may include spices like orange peel and coriander. This results an exceptionally complex and fruity beer that has seen a resurgence in popularity.

The Beer Brewing Process - The Nitty Gritty
​
​
1. The Ingredients.
Beer brewing only requires a few basic ingredients, but Brewers and crafters also tend to experiment with additives, infusions, or spices.
​
-Water
Water, the chemical of life on Earth, plays a pivotal role in brewing, making up about 90-95% of beer. The quality of water used can significantly influence the final product's taste, aroma and appearance. Different regions boast unique water profiles; for example, Dublin's high bicarbonate levels, or hard water, are perfect for stouts, while Pilsen's soft water excels in brewing pilsners. By understanding and controlling water's mineral composition and pH brewers can craft beers that showcase their distinct styles and flavours.
​
-Yeast
Often said to be the soul of Belgian beer. Specific Belgian yeast strains impart fruity esters, phenols, and spicy characteristics, playing a dominant role in shaping the beer's flavour profile.
​
-Hops
Although Belgian beers aren't usually hop-forward, hops are still crucial for balance and preservation. Traditional Belgian Varieties, like Saaz and Styrian Golding, are known for their subtle, spicy, and herbal notes.
​
-Malt
Belgian brewers typically use malted barley, though some styles incorporate wheat, oats, or spelt. The choice of malt greatly influences the beer's body, sweetness, and colour.
​
-Adjuncts
They are used by many Belgian brewers experimentally to contribute to the variety and innovation Belgian beers are reputed for. These can include candy sugar, herbs, fruits, and spices.

Mash Tuns
Mash tuns are brewing vessels used to turn the starch present in grains into sugar to be used for the fermentation process in beer brewing. acting as large cooking pots, they stew the malted barley (and other grains if used), creating a sweet liquid known as ‘wort’.
Whirlpool Systems
A whirlpool helps to separate hop particles and trub (gunk that forms in the wort boiling) from the wort before being transferred to the fermenter. The benefits of this are to remove as many of the particles out of the wort before adding the yeast.
Copper Kettles
A brew kettle, also known as a boiling pot, is used to boil and pasteurize the wort (unfermented beer liquid) prior to fermentation. It is large enough in volume to provide ample space for the ingredients, as well as for the production of foam on the surface. In recent years, alternative materials have emerged for pasteurization equipment. Stainless steel, for instance, is a popular choice due to its durability, ease of cleaning, and corrosion resistance.
fermentation tanks
A fermentation tank is used for the primary fermentation stage, where yeast is added to the wort to convert sugars into alcohol and carbon dioxide. It typically has a conical bottom that allows the yeast and other sediment to settle, making it easier to separate the clear beer from the sediments. They are usually made of stainless steel or other materials suitable for fermentation.
Heat Exchangers
Thermal treatments are a necessity when producing any beverage that will be bottled, and beer and cider are no exception. Heat exchangers provide many of these treatments, including cooling, pasteurization, fermentation and aging. A quality heat exchange system cuts down on the amount of water during the brewing and tank cleaning procedures, benefitting the brewing process and the environment.
Conditioning tanks
The conditioning tank is used for the secondary conditioning and carbonation of beer after primary fermentation. It’s the final stage before packaging. Unlike fermenters, these tanks often have a dish-shaped or flat bottom. They are designed to store and carbonate the beer while clarifying it further.
