Between 2007 and 2012 a team led by Dr Lindy Crewe from the University of Manchester have been excavating a Cypriot Bronze Age site at the south-western settlement of Kissonerga-Skalia near Paphos.
The team excavated a two by two metre domed mud-plastered structure and have now demonstrated by means of experimental archaeology and various other evidence that it was used as a kiln to dry malt for beer making three-and-a half-thousand years ago.
The form of this construction suggests that the most likely function was as a drying-kiln, and that one of the primary uses of this structure was for drying malt or curing malt cakes.
The excavation of the malting kiln with associated sets of pottery types and tools left in place gives a great opportunity to look at Bronze Age toolkits and to figure out techniques and recipes.
According to Dr Crewe, beers of different flavours would have been brewed from malted barley and fermented with yeasts with an alcoholic content of around 5 per cent. The yeast would have either been wild or produced from fruit such as grape or fig.

Whilst use of alcoholic beverages is considered an important feature of most societies, identifying alcohol production and consumption in the archaeological record is notoriously difficult.

Dr Crewe said, “Archaeologists believe beer drinking was an important part of society from the Neolithic onwards and may have even been the main reason that people began to cultivate grain in the first place.”
Important evidence comes from the well-known ‘scenic compositions’ found in tombs of the Early–Middle Cypriot Bronze Age, which have been the focus of a great deal of speculation on the nature of the activities shown and the meanings behind the imagery. The new data from Kissonerga-Skalia provides impetus for the re-interpretation of a number of the scenic compositions as narratives of the related activities of producing beer and bread.
The associated architecture and material culture is primarily of types found at Bronze Age sites elsewhere, but allows for extrapolation of some of the less archaeologically distinct aspects of beer production.
Beer production and subsequent consumption was an important feature of celebrations, used to foster community cohesion during the Early–Middle Cypriot Bronze Age, and may even have been manipulated to create inequalities during the transition to the Late Cypriot Bronze Age.
The oven discovered by the archaeologists was positioned at one end of a 50 metres square courtyard with a plastered floor.
The archaeologists found grinding tools and mortars which may have been used to break down the grain after it was malted, a small hearth and cooking pots made of clay to cook the beer gently. They also found juglets, which it is believed, probably contained yeast additives or sweeteners to produce beers of different strengths or flavours. Beer ingredients were found by the team as carbonised seeds.
Crewe added: “Beer was commonly drunk because it is more nutritious than bread and less likely to contain harmful pathogens than drinking water which can make you ill. But alcoholic beverages were also used to oil the wheels of business and pleasure in much the same way as today: work brought communities together for tasks such as bringing in the harvest or erecting special buildings. Instead of payment, participants are rewarded with a special feast, often involving quantities of alcohol, which also transformed the work from a chore into a social event. The people of the Bronze Age, it seems, were well aware of the relaxing properties of alcohol.”

In August 2012, an experimental archaeology team, led by Ian Hill of HARP Archaeology, recreated the drying kiln using traditional techniques in order to test Dr Crewe’s theory. The field school replicated the installation to a working level in order to test its functionality and suitability for malting grain.
The structure was built with a domed roof, a large entrance and a sunken pit near the entrance to house a large pot used as the firebox of the kiln. The theory being that heat generated from the fire would rise and circulate around the dome, with the most intense heat remaining within the pot. By covering the entrance to the installation with temporary doors and building a chimney into the domed roof, the temperatures and airflow within the dome could be further controlled.
This modern version used hot air to produce a temperature of 65° C – perfect conditions for heating and drying grains but still preserving it’s enzymes and proteins.
Ian Hill said: “After the beers had been strained, we felt they were all pretty drinkable, though some varieties were better than others. The grape was less pleasant - a bit too sweet– the outcomes are less reliable when using wild yeasts, compared to brewers yeast, but the fig beer was definitely the most popular.”
Information for the 2013 Field School will be posted in early 2013, but for more information regarding the project and to express an interest in participating please contact here.

Ingredients
1.5 Kg fresh, wild barley
5 large, wild figs (unwashed)
Plenty of water
• Using a porous sack, soak 1.5 Kg of the barley grains in cool running water for 24 hours. A fresh running stream is ideal.
• Drain the grains and remove any unwanted stalks etc.
• Spread the grains evenly inside a semi-porous container (a shallow pottery vessel or wooden bowl for instance) and cover the container with a damp cloth and place the container out of direct sunlight.
• Uncover every 6 hours to stir the grains, so to avoid overheating and moulding and repeat until germination phase is complete (usually 3-4 days).
• Once the grains have germinated they are ready to malt. Split open a grain to check the germination, once the inner shoot of the grain has grown to around 75% of the length of the grain they are ready.
• To malt the grain place in open containers and put them into the bottom of your drying kiln, once positioned fire up the kiln and maintain a steady fire for 24 hours. This will produce a steady temperature of around 60C for malting your grains to produce a pale malt.
• Once malted take your grains and crush using a quern stone and grinder, the grains should be crushed in order to open them and allow liquid so that sugars can be absorbed, but not crushed so much as to make flour.
• Heat 3.75 litres of water in a large cooking pot to between 65and 70C. Add the crushed malt and stir through. Cover the vessel and remove from the heat, but ensure that the temperature does not fall below 65 or above 70C (if necessary add cold or hot water to help maintain the temperature) and leave to mash for 90 minutes.
• Heat a further 3.75 litres of water to 75C in a separate cooking pot and prepare a third, sealable, vessel which will be used to ferment the beer in.
• Once the mash is complete strain the contents of the mash through a porous material, such as cloth, into the fermentation vessel. The grains will be held in the cloth whilst allowing the sweet liquid wort to drain into the fermentation vessel. To get the maximum amount of sugars from the grain and into the wort take the second vessel of heated water and pour over the grains to drain into the fermentation vessel.
• Once the fermentation vessel is full, heat to a high temperature to kill any germs or bacteria. The wort must then be cooled by placing the fermentation vessel into cold water (being careful not to let any of the water into the vessel).
• Once the wort has been cooled take the figs and gently crush them in your hand before placing them inside the fermentation vessel. Seal the fermentation vessel and leave in a cool place, out of direct sunlight for 5-6 days, by which time your beer will be ready to drink.

I’ll miss the pings...
Same here. I’ll miss the pings.
you might also want to get your kidney function checked..
/johnny
SunkenCiv, thanks for all that you do to chronicle new discoveries about things of the past.
Others will benefit from your massive effort to document information of whatbhasngone before.
I, too, will miss the pings, but thoroughly understand your position, and for the need for re-evaluation. Seems we are all about to experience great change, and how to prepare for it is elusive.
Best to you, FRiend!
I’m sorry that I only recently became a member of your ping list.
I’m also very sorry that people are blaming you for multiple pings. Software glitches occur all over the Internet and you should not take the blame for them.
If you do set up a place for SunkenCiv, you can certainly count me in as a member. I’m sure I’m not alone here. :)
I understand certainly and it’s a damn shame. Thanks.
I will of course have to steal that graphic.
Thanks, all, for those kind remarks.
And, yeah, that was pretty funny.
Just Damn! I truly understand why you’re going down that road. I just want to thank you for the enormous amount of effort you put into all this. I, frankly, have been in awe of all the information you have enlightened me with.
Thanks SC!
Thank you very much for your dedication and service all these years - Yours has undoubtedly been my favorite and my longest participated pinglist of all time. And it will be sorely missed. :(
Thanks for your effort all these years.
Thanks very much!
I am sorry to hear you will no longer be heading the ping list for GGG.
I have not always been available to comment, but I look forward to seeing your “name” and discovering the fascinating information you sent that day.
Your service will be missed.
Illegitimi non carborundum
I was getting to the point where I was roused to complain about the multiple posts of ping lists. I had assumed that my name somehow got on the long lists more than once. Your advice that the problem is systemic is helpful. It’s sort of like Obama........ must be endured.
Please know that in spite of the sorta opus, we do appreciate and value your effort. The list topic is broad and some titles are read and the article is skipped because it is not within the scope of our interest. But........many are read all the way through and then again
I’m sorry that this is going to be your last ping. I’ve enjoyed them immensely and have learned a great deal from many of them.
Datburnit! GGG is great reading. Thanks for all the effort you put into it over the years.
