When the climate turns chilly, nothing melts the chilliness away fairly like a Scorching Toddy, Irish Espresso, or a mug of mulled wine. For beer drinkers, although, winter-friendly choices are usually restricted to stouts, barleywines, ambers, and Bocks — all of that are usually served chilly. That’s to not say that they don’t present some warmth as soon as consumed, however the beer world doesn’t current any apparent choices when one needs to cozy up with a heat drink.
But, as is the case with so many points of the beer world, the Germans found out a method round this dilemma centuries in the past, and stateside breweries are lastly catching on. It’s referred to as “Bierstacheln,” which interprets to “beer spike.” The method entails plunging a purple scorching metallic poker right into a glass of chilly darkish ale or lager, thus reworking it right into a caramelized beer brûlée of types.
The Origins of Bierstacheln
Whereas we don’t know precisely when the apply first happened, we are able to pin its creation to after lagers had been invented, someday within the 1400s in Bavaria, since that model was the primary to obtain the Bierstacheln therapy. Again then, business refrigeration didn’t exist, so brewers would retailer casks of beer in freezing chilly caves to maintain them each cool and recent by means of the winter.

In response to Germany’s oldest brewery Weihenstephan, drinkers typically discovered these lagers to be too chilly to really get pleasure from within the useless of winter, so blacksmiths conjured up the thought to stay piping scorching iron spikes, or “stacheln,” into lagers to carry them as much as appropriate consuming temperatures.
How Does Bierstacheln Work?
The method doesn’t make the beer scorching, per se, however warms it simply sufficient to forestall the chilly shock that an icy sip usually delivers. The remainder of Bierstacheln’s advantages arrive by way of textural and aroma adjustments — plus a bit spectacle for good measure.
Though the apply originated as a technique to warmth up any sort of German lager, brewers ultimately discovered that Bierstacheln has essentially the most profound transformative results when utilized to darker, maltier types.
Since most darkish beers include a good quantity of residual malt sugars after fermentation, the temperature of the metallic rod causes these sugars to caramelize upon contact. Because the metallic sizzles within the liquid, a heat layer of creamy, sugary foam rises to the highest of the glass, which brewers declare exudes a “toasted marshmallow aroma.” Moreover, the method causes the beer to launch a big portion of its carbonation, leading to a softer mouthfeel. Upon taking a sip, drinkers are greeted with a kiss of scorching foam adopted by a contrasting semi-chilled, silky swig of darkish beer.
As of late, most breweries use metal over iron, and heating sources for the rods fluctuate between scorching coals and open flames. So as to present ample room for the beer to foam up as soon as the rod has been submerged, the glass ought to solely be half-full.
Whereas Bierstacheln works — in idea — with all beer types, it’s greatest to use the ritual to beers with a excessive content material of residual sugar. Meaning malty lagers and high-gravity beers. Suppose amber lagers, Bocks, Doppelbocks, porters, stouts, and barleywines. If a beer has a ton of hop expression (IPAs) or employs predominantly lighter malts (Helles lagers and pilsners), Bierstacheln will subdue the brew’s aromatics fairly than improve them. It received’t wreck the beer, it simply received’t ship the complete Bierstacheln impact.
