The taste of a good pils according to Bart Durlet

Bart: “Pilsener quenches your thirst like no other beer, that’s why I would expect a bitter taste.
Take the new Maes, for example. This one is far maltier and contains more hops than the previous one, so it’s more bitter.
The brewer is after a subtle touch of bitterness, never acerbic, and a brief, dry aftertaste. Above all, a pils has to be pure, with just a short aftertaste and then a neutral mouth feel.
The ingredients of Pilsener are barley malts, with the possible addition of raw grains such as wheat, maize or rice, plus hops and yeast. It has to have these basic ingredients in abundance. However, quality ingredients do not always make for a good glass of Pilsener.
A well-drawn or poured pils is transparent. You can see straight away how well it has been filtered. Also, pils has a low alcohol content - 4.5% to 5.5% - so, as a brewer, you cannot hide your mistakes. If your Pilsener contains unwanted diacetyl, you cannot fail to notice it. It is important to drink your pils as freshly as possible from a cold glass.
Beer’s main enemies are oxygen, light, grease and heat. A freshly poured pils will go flat after only two minutes. Bart reckons it takes two minutes to empty a glass."
Draught Or Bottle?
The unanimous opinion is that it should be on draught. You get more volume, which slows down oxidisation and you don’t get a whiff of something strange you don’t want. Also, as a rule, draught beer is always fresher and younger. What exactly do you taste, and how do you go about it?
Tasting is observing. All beer tasting starts off with observation: examine the colour and the structure of the froth. How does the froth collapse and does it leave traces on the glass (side adhesion)?
Does it have the typical pilsner colour? Clarity also plays a major role. A well-filtered beer is clear. It is also of major importance that the beer is poured into a clean glass, which should be free of grease and fingerprints.
The next step is smell. There are hundreds of aromas to be found in beer. If you can smell bananas, this doesn’t always mean that banana has been used as an ingredient. For example, there are types of hops, which have a pronounced grapefruit aroma.
There is a near to endless range of aromas and flavours: pleasant flavours, from flowers, herbs and fruits to unpleasant smells such as musty, wet cardboard, rancid butter or ‘puttekesgeur’ (a drainy smell); all of which indicate mistakes made during brewing or fermentation.
The four basic tastes are sweet, sour, bitter and salt. Beer has all these flavours except for salt. You will find the other three in abundance and often combined! Unlike wine, beer has to be swallowed to taste it properly. The taste buds for bitter are at the back of the tongue; sour is on either side and sweet is at the tip of the tongue.
What To Look Out For?
“Learn to recognise what a brew should taste like so you can tell when it’s off. Consistency is a brewer’s main challenge, as his customers will expect the same beer with the same taste every time. This requires strict supervision of the brewing process. Smaller breweries rely on the nose for a final decision.”
First, Bart judges the beer’s appearance: colour, clarity, froth. He then lifts the glass up to his nose. A slight shake and turn of the glass will set free the aromas of the hidden ingredients. Then, he puts the glass to his mouth and takes a sip to savour the first taste impressions.
The rising temperature of the beer in the mouth, and the movement of the brew, will free up transient ingredients, which are observed through the taste buds in the mouth and the olfactory nose membranes. This allows Bart to judge the aromas. He then proceeds to research the aftertaste, the ‘mouth’, the carbon dioxide saturation.
And The Difference Is...
A blind pils tasting by the Belgian consumer association 'Test-Aankoop' (*) gave the highest rankings to Estaminet, Bockor and Maes. Bart is getting stuck into Maes, Jupiler, Estaminet, La Trappe Puur and Kaai Bier. I want to know if the beer is too warm. “No, it isn’t. For a tasting, I like a temperature around 10°C,” Bart declares.
“If the beer is too cold, you can’t taste anything.” The brewer pops open the bottle and listens. “Just hear the ‘ssssht’ made by the escaping carbon dioxide.
There shouldn’t be too much froth!” When pouring, he checks how the froth reacts, if there are pearly bubbles in the beer and also its clarity. Bart is now swirling the beer around in the glass.
He tucks his nose in and savours the aromas, which have now been freed. Bart: “Above all, I use my nose to taste. In this lot of Maes pils, I get unwanted aromas such as ‘paper’, ‘cardboard’, ‘metal’ or a ‘pasteurised’ taste.” Immediately, he points out the importance of storage.
Pils is best enjoyed at around three months; six months is about the limit at which you can keep it. This batch of Maes is unconvincing as the beer is not fresh enough. Jupiler is all things to all people, as it is malty, fruity and mild all at the same time. Bart detects a typical ‘grain aroma’ in this crystal clear and very fresh Pilsener. Our beer taster is less complimentary when it comes to the Estaminet (Palm): “Mild, subtle, fruity but not enough bitterness for a pils. I won’t have a second one.”
Number four is the odd one out. La Trappe Puur is a pils from a Dutch Trappist brewery. Unlike our other Pilsners, this one is unfiltered. Cloudy flakes are dancing around. You have to pour this one slowly and carefully.
“A tasty pils with a lovely flower aroma, plenty of hops in the nose with a primarily dry bitterness. Great aftertaste,” is Bart’s opinion. La Trappe Puur is brewed with pure hops without using extracts.
We finish off our tasting with Kaaibier. This unfiltered pils is produced exclusively for brasserie De Bierkaai (www.bierkaai.be) in Heusden-Zolder. It is the only one of our five pilsners that continues to ferment in the bottle. Kaaibier is slightly fruitier and has a taste reminiscent of La Trappe Puur, with equally prominent hop flavours.
