In 1860, Belgian Eugene Rodenbach went to England to learn brewing. At that time, the most popular beer there was the London Porter. It was aged in giant barrels of 100,000 liters. The more it was aged, the drier and more sour the beer became. Not everyone could afford to drink beer that had spent several years in a barrel. That’s why in pubs they mixed beers of different ages into one glass.
On his return to Belgium, Eugene reproduced the porter production technology at the Rodenbach family brewery and obtained the first samples of Flemish ale.
Basic facts you should know about the production of Flemish ales:
— When brewing, predominantly light malt is used with a small addition of dark, roasted varieties.
— Unflavored, old hops are used. It is added at the very beginning of brewing so that it does not give bitterness and flavor, and does not interfere with the balance of the ale.
— Mixed fermentation is used. After brewing, cultured brewer’s yeast and lactic acid yeast are added: the former converts the sweetness from the wort into alcohol, the latter adds sourness.
— The beer is aged in a barrel or tank. From 8 months to 3 years the wort is kept in special oak tanks. They give the beer wine notes.
— Aged and young beer is blended. After the beer has been in the barrel for more than a year, it is mixed with less aged beer. This is how you get the perfect blend of flavors.
Flemish red ale is produced using red-brown malts and aged in oak barrels for two to three years. As a result, the beer interacts with sour bacteria, which imparts a characteristic sourness to the flavor. To reduce the tartness, younger, sweeter beers are added, which increases the flavor and complexity of the finished brew, and adds carbonation (carbonation) to the final product.
Flemish red ales tend to be pungent and bracingly tart, with a fruity and winey flavor. The aroma is winey, with hints of fruit. The flavor is dominated by vinegar sourness, plum, cherry, currant and orange. Also in the red ales one can feel the oak barrel. It opens with notes of vanilla, wood, spices and tannins. Red Flemish ale is produced with a small addition of dark roasted malt, but still the base is light. The fruity and sour profile of the drink dominates.
Another mixed sour ale from Flanders is called Oud Bruin, or flanders brown — a Flemish brown ale. Although it is often considered the equivalent of Flemish red ale, these styles are quite different (also, Oud Bruin originated in East Flanders, not West Flanders — this matters to the Flemish).
While Flemish red ales have a pungent flavor, Oud Bruin tends to be more malty and somewhat sweeter, with notes of ripe plums and raisins, and much less tart. As in Flemish red ales, the fermenting bacteria traditionally come from tall oak barrels where the beer is aged. But many modern versions are fermented in stainless steel vessels, with yeast and bacterial cultures added.
In brown Flemish ales, more dark, heavily roasted malts are added. Therefore, bread notes and caramelization are felt in the flavor. The flavor and aroma of brown Flemish ales is fruity and malty with sourness. It contains plums, dates, dried fruits. Maltiness is expressed in hints of caramel, chocolate and molasses. The longer the brown ale is aged, the more distinct the acidity is felt.
Despite its Belgian origins, the inspiration for the Flemish red ale is likely to have come from the sour blended porters that once dominated the English beer market. The godfather of the style is considered to be Eugene Rodenbach, who trained in brewing in England and brought porter blending techniques to Belgium. Rodenbach created the first examples of Flemish red ales at his family brewery. Rodenbach sour ales, with their deep red color, are characterized by a berry and plum flavor with notes of balsamic vinegar and an inherent sourness that is created by the bacterial fermentation of the wort in oak barrels.
There are many articles on the internet that say roughly the same thing, yet one says Flemish ale and the other says Flanders ale. And any person, even a biergic, might have a question: what is the right one?
Both red and brown Flemish ales are produced in Flanders, a region in the north of Belgium. But Flanders is inhabited by the Flemish.
If we talk about the Rodenbach brewery, and they are the originators of this style, they have «FLEMISH» written on the bottle. The BJCP (world beer style chart) also has a section for «Flemish ales.»
The most famous Flemish ale that comes immediately to mind is Bourgogne des Flandres. It is made using a different technology from the classic Flemish ale. It’s also labeled «lambic» or «brune» on the bottle.
To find a classic Flemish red ale on the store shelf, look for «flemish» on the label and read about the beer’s production. It should be aged in barrels. If you want to find a brown Flemish ale — the label will say «oud brun».
And you can try it in any beer restaurants of the Lambic chain. We are waiting for you!
Coffee and beer are drunk at different times and on different occasions, but they have much more in common than meets the eye. Beverages that were considered ordinary 10 years ago have now become gourmet products: craft beer and specialty coffee have won millions of fans. But what if you mix the two? Let’s find out how justified this combination is and what myths are associated with it. How did the combination of coffee and beer appear? Experiments with coffee and beer began in the middle of the XX century, when brewers and bartenders began to look for new flavors. But the real boom happened in the nineties and noughties due to the growing popularity of craft beer. The first successful variants were coffee stouts and porters — dark brews with deep flavors that perfectly complemented the coffee notes. Brewers added coffee at various stages: — during brewing — for a rich flavor;— during fermentation — for softness;— into the finished beer — as a cold coffee infusion. A good example of such a recipe is the Japanese beer Hitachino Nest Espresso Stout, which can be tasted in Lambic beer restaurants. It’s a flavorful, dense ale brewed in the style of American imperial stouts with coffee beans added for espresso. Bartenders, too, have contributed to popularizing this unusual combination, creating original cocktails from coffee and beer. The most popular is the Black & Tan, which includes stout, lager and espresso. Today, such mixes are part of the craft culture. Is it true that coffee helps sober you up? One of the main myths is that coffee supposedly neutralizes alcohol. In fact, caffeine only masks intoxication. It creates the illusion of liveliness, but coffee does not actually lower blood alcohol levels. In addition, a cocktail of coffee and beer can increase the strain on the heart. If you drink coffee before alcohol, it will temporarily increase the activity of liver enzymes that break down ethanol. But this does not mean that it is necessary to increase the dose. Coffee with beer: harm or benefit? In moderate quantities, low-alcohol coffee beers (for example, stouts with 4-6% strength) are relatively safe. If you want to try such a mix, choose drinks from quality ingredients. For example: — Dark beer (porter, stout) and cold espresso.— Lager or ale and light coffee syrup. There are contraindications for such cocktails. Mixing coffee with beer is not recommended for people with hypertension, heart and GI diseases, as well as those who use drugs incompatible with caffeine. The combination of coffee and beer is an interesting gastronomic experience, especially if you respect the measure. Come to Lambic — we will treat you to interesting drinks without harming your health!

If you’ve scrutinized craft beer labels, you’ve definitely seen the mysterious IBU abbreviation on them. This indicator plays a key role in shaping the flavor of the beverage. Let’s find out what it means and why bitterness is one of the main criteria for evaluating beer. What is IBU? IBU (International Bitterness Unit) is an international indicator of beer bitterness. It indicates the concentration of isohumulone, an alpha acid found in hops, which gives the drink its characteristic bitterness. The higher the IBU, the more bitter the beer will be. However, the perception of bitterness depends not only on this indicator, but also on the balance with malt sweetness, strength and aromatic additives. Why do you need the IBU index? Before the advent of industrial brewing, a beverage could be either too sweet or, conversely, too sour or bitter. To achieve a harmonious flavor, brewers began to adjust bitterness with hops. In the past, herbs (thistle, mint, juniper) were used to soften sweetness, but today the main source of bitterness is hops. It is added at different stages of brewing to: — compensate for the sweetness of the malt;— add complexity and flavor to the beer;— increase shelf life (isohumulone has antibacterial properties). The first to calculate the bitterness of beer were the people of Great Britain, using the formula «pounds of hops per quart of malt». The modern IBU standard was developed to accurately categorize beers. How to calculate IBU? The bitterness index is determined using a mathematical formula: G = D × E D = (A × B) / (C × 0.1) Where: A — mass of hops (in grams); B — alpha acid content of hops (%); C — wort volume (in liters); E — loss factor (production time and beer density are affected); G — final IBU. The longer the hops are brewed, the more alpha acids pass into the wort, increasing bitterness. IBU scale: from lager to IPA Beer bitterness is measured on a scale of 0 to 120+ IBUs, but most beers are in the 5-90 range. Beer Style IBU Level Characteristics Pale Lagers 8–15 Light, smooth, minimal bitterness Wheat Ales 10–20 Fruity notes, low bitterness Porters/Stouts 30–50 Coffee, chocolate tones, moderate bitterness American IPA 50–80 Strong hop bitterness, citrus and pine notes Imperial IPA 80–120+ Extreme bitterness, high alcohol content Why is IBU not the main selection criterion? A high IBU does not always mean that the beer will seem too bitter. For example, sweet stouts (30-50 IBU) seem less bitter than IPAs due to caramel and chocolate notes. And light lagers (8-15 IBU) may be perceived as more bitter due to a lack of malt balance. How do you choose a beer based on bitterness level? If you don’t like bitterness — choose lagers, wheat ales, Belgian trippels (up to 30 IBU). If you like balance, try porters or amber ales (30-50 IBU). If you like a rich hop bitterness, an IPA or Imperial Stout (50+ IBU) is ideal. You can try any of these varieties in Lambic beer restaurants. Come — we will find something to surprise you!
