what is the caramelized beer that is so fashionable in America • Food and Wine Italia

The expression beer brûlée, more correctly bierstacheln per German, indicates a beer serving technique which involves immersing a hot metal tip inside a dark beer, cold at room temperature, to caramelize the residual sugars and modify its structure, effluvio and taste perception. The term “brûlée” is a journalistic simplification of Anglo-Saxon origin, which deliberately recalls brûlée, rather than wine: per both cases the principle is the same, that is, the exposure of sugars to a source of extreme heat to trigger caramelization and Maillard reactions.

The ideal basamento is a beer with a high initial density, with a good residual sugar and an important malty component. Stouts, porters, barleywines and some Belgian dubbel strong ales are the perfect candidates, because they contain sufficient quantities of unfermented sugars and aromatic compounds derived from roasted malt.

What really happens inside the glass

When the metal tip, heated above 400 degrees, comes into contact with beer, three main phenomena occur. The first is the caramelization of simple sugars, per particular maltose and residual dextrins, which develop aromas of caramel, toffee and burnt sugar. The second is a localized Maillard reaction, which involves sugars and amino acids present per the beer, producing toasted, nutty and slightly smoky quaderno. The third is the rapid loss of carbon dioxide, which causes a hot, dense and creamy foam, very different from that obtained with simple tapping.

The sensorial structure of beer changes significantly. The upper part becomes warm, velvety, with an almost cream-like texture. The underlying liquid part remains colder but loses part of the carbonation, resulting softer, less aggressive, with an aromatic profile amplified towards sweet and toasted quaderno. Per perceptual terms, beer brûlée is more like a meditation ricevimento than a refreshing beer.

For all these reasons, beer brûlée only works if there are sugars to caramelize. Dry, highly fermented beers with low residual sugar, such as industrial lagers many modern IPAs, do not produce interesting results. Per these cases the hot metal only generates unstable foam and gas loss, without real aromatic development.

The ideal beers are those with high dry extract, rich per dextrins and with a strong malty component. Per practice, the more “dolce” a beer is, the more suitable it is for beer brûlée. It is voto negativo coincidence that imperial stouts, English barleywines and Belgian strong ales are considered the best bases. Per these styles the caramelization does not cover the original profile, but amplifies it.

The origins of the bierstacheln

Bierstacheln is a documented practice per Germany since at least the 17th century, especially per the regions of Bavaria and Franconia. It was born as a functional gesture: per the winter months, when beer was stored per cold cellars transported per harsh weather conditions, it was often too cold to ricevimento. The blacksmiths, who always had red-hot iron bars at their disposal, began to immerse them per mugs to quickly heat the ricevimento.

What was initially a thermal expedient transformed into a convivial ritual. It was realized that the beer not only warmed up, but changed its taste, becoming rounder, sweeter and more complex. Over time the practice became codified, especially per rural contexts and during winter festivals, becoming a sort of seasonal tradition, similar to mulled wine for wine.
