During the final Ale through the Ages program of the 2011-2012 season at Discovery World on March 22nd, we were honored to have University of Wisconsin-Milwaukee Professor of Anthropology Bettina Arnold and her German colleagues, Sabine Hagmann (State Monuments Office Baden-Württemberg Hemmenhofen) and Rosemarie Stadler (Federseemuseum), as guest presenters. This special brewing program, titled, “Power Drinking and Power Dressing in Iron Age Germany” celebrated the “beer and bling” of the continental Celts from southwest Germany.
The evening of the event, guests were treated to samples of “Keltenbräu”, a recreated Iron Age beer that was brewed by Dr. Arnold and I specifically for this program. The recipe was derived from archaeological evidence excavated at several Iron Age sites in SW Germany (Stika 2011). The Keltenbräu consisted of German malted barley (Weyermann, pale, roasted, smoked and acidulated malt) and flavored with mugwort (Artemisia vulgaris) and carrot seeds (Daucus carota). 6 gallons was fermented with a standard American Ale Yeast, while another 6 gallons were fermented with a Roeselare Ale yeast (saccharomyces and brettanomyces blend). At 6% ABV, the resulting beverage was a mahogany-colored slightly smoky ale, with a distinct tart finish from the mugwort. 1 lb of wildflower honey was added to the standard ale yeast batch for balance and contrast to the sour Roeselare Ale yeast version.

Power Drinking & Power Dressing
The recipe that we chose to brew for this special program was an Iron Age honey mead, found in a bronze cauldron at the foot of a Celtic chieftain who was buried in a central burial chamber, beneath an earthen mound near the village of Hochdorf in southwestern Germany. Excavations led by Dr. Jörg Biel in 1978-79 revealed that this elite male was buried around 550 BCE. To discover an intact burial chamber from this period was a rarity, as most were looted over the centuries. Included in the burial was a wagon with nine bronze plates and three bronze serving platters. Nine large gold decorated drinking horns, likely aurochs horns. Eight of them could hold 1 liter of liquid, yet the largest horn which hung above the chieftain’s head could hold a 10 pint (5 liter) capacity (that’s a “power drinker”). Additionally, a very large Greek-imported bronze cauldron with a capacity of 70 gallons (ca. 265 liters) was placed at the chieftain’s feet. Upon analysis of the desiccated remains, it was determined to have once been mead (honey wine). Such a volume of mead was quite an extravagance and very expensive to obtain, particularly considering the Celts did not have formalized apiculture.
Therefore, it was an outward symbol of power to procure that much honey and then ferment it for ritual consumption during the mortuary feast. It isn’t entirely clear whether this mead was intended for the deceased upon his arrival to the afterlife, or if it was for the attendants at the burial of the Hochdorf chieftain. Nevertheless, it was this mead that we recreated during this special Ale through the Ages program and it was the textiles found in the grave itself that were recreated and modeled during this event.
Etymology of “Mead”
The earliest surviving written notation of mead comes from a hymn in the Rig-Veda, one of the sacred books of Hinduism dated around 1700–1100 BCE, in which it states “In the wide-striding Vishnu’s highest footstep, there is a spring of mead.” The etymology of the word mead can be traced to the Sanskrit word, madhu, which became the Old English word Medu and German Met, all of which are the precursor to “mead.” Indeed, the term “honeymoon” is considered to be derived from the tradition of newlyweds drinking mead for one month (one moon) following their wedding to ensure fertility. In pre-historic Europe, mead was considered the drink of Celtic royalty and has been found in many archaeological contexts, not only in Germany, but also into Ireland and beyond.
Power Dressing
What also made the Hochdorf burial so remarkable was the state of preservation of the textiles. Rarely do 2,000 + year-old textiles survive in the archaeological record, so when they do, it “literally brings the individuals who wore the costumes back to life” (Dr. Bettina Arnold). Textiles are commonly underappreciated as outward symbols of status, particularly considering the amount of time and labor required to produce them in antiquity. After tallying up all of the hours it took to reproduce a costume from this period, it came out to 1,762.5 hours for just the fabric alone. The rarity of natural red and blue dyes in continental Europe in the Iron Age would have also acted as visible symbols of status. This Celtic Period costume consisted of a red woven undergarment made of wool with a blue diamond boarder, a blue cloak with embroidered meander and swastika patterns (common symbols found throughout the ancient world), leather pointed-toe shoes with gold filigree, bronze cloak pins (fibulae), bronze hair pins and a large pattern-embossed bronze belt plate. Taken altogether, it is clear that they way someone dresses (even in this day and age), offers insight into a person’s socio-economic status, as well as the context in which the costumes were worn. It is much like today’s cultural rituals of dressing the part when attending award banquets, weddings, funerals, etc.
Hochdorf Mead
As previously mentioned, the mead we were recreating was based on evidence found in a bronze cauldron buried with a Celtic chieftain at the site of Hochdorf in southwestern Germany. Palynological (pollen) analysis performed by Udelgard Körber-Grohne, showed that the residue contained pollen from at least 60 different plants. The two most common pollen types were thyme and meadowsweet. Thyme (Thymus vulgaris), is a small shrub bearing small pink flowers in midsummer which attract bees. The fact that thyme pollen was the most common type found in the Hochdorf mead sample indicates that the honey was collected in mid-late summer. Additional pollen found in the Hochdorf mead residue was that of meadowsweet (Filpendula ulmaria or Spiraea ulmaria). Also known as bridewort, queen of the meadow and meadwort, it is a perennial plant with creamy white flowers. Archaeological evidence points to it being a common brewing addition in Europe for millennia. It was also traditionally used for medicinal purposes as an anti-inflammatory, antacid and for fever relief. It is likely therefore that the pollen in the Hochdorf mead residue accounts for the pollen the bees collected on those flowering plants during the late summer.
The honey we used in this mead was donated by the Urban Apiculture Institute here in Milwaukee. This was wildflower honey also made during the late summer from the flowers of Goldenrod and Aster. So to account for the thyme and meadowsweet pollen in the original Hochdorf mead, both of these were added in small amounts to our mead during the brewing. In order to preserve the subtle honey aromatics the 12 gallons of sweet liquid was kept below boiling temperature for 30minutes. The resulting Original Gravity came in at 1.18 (25˚Plato)! Six gallons were fermented with lambic yeast to convey the wild yeast flavors, while the other six gallons were fermented with a sweet mead yeast. Fermentation began in earnest and continued steadily for two weeks. Typically mead should be allowed to ferment for months, but this class was on a schedule and could not wait that long.
Therefore, after two weeks the gravity dropped to 1.040 (10˚Plato) on both carboys, i.e. 10.5% ABV. In order to mitigate the potential for continued fermentation in the bottles, a small amount of potassium sorbate was added, whereby making the yeast dormant. The resulting flavors were delicious, sweet indeed with a hint of thyme and a warming wine-like finish. Ninety-five 12 fl. oz. bottles were filled, capped, labeled and taken home by the program participants, thus ending the 2011-2012 Ale through the Ages season. Certainly this special Hochdorf Mead will age splendidly and hopefully evoke the fermented flavors of the European Celts whose cultural power continues to influence Western Civilization.
