"Most early Celts were subsistence farmers living on agriculture and animal husbandry. However, increasing social differentiation and division of labour in princely seats meant that the farmers in the surrounding area had to produce more than their own subsistence alone. In the early days of the mud-brick wall 600 – 550 BC, some five thousand people had to be supplied with food at the Heuneburg. Remains of plants and pollen analyses show that additional supplies of barley and spelt were brought in, as were pigs and cattle, together with sheep and goats the most important early Celtic farm animals. For the first time in north central Europe, animal bones found at the Heuneburg provide evidence of domestic chickens that had come to the upper Danube from the Mediterranean."
"Early Celts ate grains and legumes, vegetables, meat and fruit, and even garden herbs such as parsley and dill were part of their diet. Provisions had to be protected from moisture and rodents. The Heuneburg food supplies were kept in large clay pots placed in storage rooms on stilts. Other vessels were used as cooking pots, as soot marks on their bottoms and outsides show. Dishes and bowls of various shapes and quality were used not only for the serving of food and beverages, but also for eating and drinking. From the barley-malt kilns found at the Hochdorf settlement we know that the early Celts enjoyed their beer."
