Field Marshal Otto Krieger

5-Gallon All-Grain Homebrew Recipe

THE CHARACTER

In the spring of 1912, when the first cylinders fell burning from the sky and the tripods rose from the craters like iron nightmares, the world panicked. Governments froze. Armies scattered. Civilians fled. Field Marshal Krieger did not flee. He organized. He strategized. He stood in front of frightened men and spoke with a calm so absolute that they believed him when he said they would win — even though every piece of evidence suggested otherwise. He studied the machines. He found their weaknesses. And when Oktober came and the final assault was mounted, it was Krieger who led the charge that brought the last tripod crashing to the earth. His Oktoberfest Märzen is brewed in March and lagered through the long summer — patient, disciplined, building in strength and character until autumn arrives and the waiting is over. A Field Marshal doesn't show up every day. He arrives when he's needed.

THE STYLE

Märzen — German for "March beer" — is a style born from the practical realities of pre-refrigeration brewing in Bavaria. Before the advent of modern temperature control, brewing during the hot summer months was both difficult and dangerous. Warm temperatures promoted bacterial spoilage and wild yeast contamination that could ruin an entire batch. In 1553, the Bavarian Brewing Ordinance officially prohibited brewing between April 23 (St. George's Day) and September 29 (Michaelmas).

To ensure a beer supply through the summer, Bavarian brewers would produce an extra-strong batch in March — the last month of the brewing season — using extra malt and hops to help preserve the beer through the warm months. These beers were stored (lagered) in cold alpine caves and deep cellars packed with ice, slowly conditioning through the spring and summer. By September, when the new brewing season began, the remaining March beer needed to be consumed to make room in the cellars for the fresh batch.

This tradition of consuming the previous season's stored beer at the start of autumn eventually became formalized as the Oktoberfest celebration. The first official Oktoberfest was held in Munich on October 12, 1810, to celebrate the marriage of Crown Prince Ludwig to Princess Therese of Saxe-Hildburghausen.

The style itself has evolved over the centuries — modern Munich Oktoberfest beers have become lighter and more golden. But the traditional amber Märzen — rich, malty, toasty, and balanced — remains the most beloved expression of the style and the beer most associated with autumn celebration. Krieger's Märzen is the traditional amber version. Not the modern pale imitation.

This is the SEASONAL beer in the Duffy & Ward lineup. Brewed in spring. Lagered through summer. Released in autumn. Gone by winter. Anticipated, celebrated, and then it disappears — until next year.
