History of Hop Trading

Written proof of hop trading appear together with written reports about hop growing. Hops were exported on carts, waggons and by river in the llth century. They went mostly to Prague Bavaria and Hanse town. The location of Prague in former trade, the way of building roads, which ran from Prague in all directions, made this town a centre for hop, grain and cattle trade. The main road went through Zatec to Nuremberg and was known as the King's road and the North salt route. The trade with the seaside towns had increased by The reign of King Charles IV., who in 1375 made a journey to Luxemburg where he made negotiations about trade among coastal countries and the Czech country. We do not know the amount of this export at this time, but it probably was not much. They used to sell surplus only.

Only with the progress of production and the foundation of towns was there an increased amount of beer drinking and so hop growing. From the point of quality there was growth of so called hop growing towns, which as opposed to field growing had more of a trading character, and were orientated more towards quality. Over the years the demand for Czech hops increased. You could find them in Lithuania, Brandemburg, Hamburg, Italy, Flanders and others. On the river Elbe it was shipped to Hamburg on so called Forum humulli. In 1546 Ferdinand I. could order a tax on hops, because the demand could not be endangered even by high custom's duty.

At that time it was well known, that the best hops were from Klatovy, Zatec and Ustek. Particulary Klatovy for its advantageous distance from Bavaria and with that a cheaper transport, was looked on as a source of quality hops. It was so good, that the town founded a special seal in the year 1533 by which hop originality was ensured. The same arrangements were also made by other towns a few years later, mostly in Zatec and Rakovnik. In the second half of the lóth century Klatovy hops had lost their popularity. The bavarian attention was set on better hops in the Zatec and Ustek areas. The interest and high quality of these hops brought about falsification attempts. Less valued and cheaper hops were sold as though from Zatec. These efforts were so big, that even arrangements of the towns against it were not successfull. So Marie Theresa had to rectify the situation by her letters in 1758 to 1784.

To mention the technical side of trade, either the brewers came to buy hop themselves, usualy from their favourite town and grower or the merchants with their own or purchased hops went to the distant breweries and offered the hops. While the first way of trade was a safer way of purchase for the customers than the other which faced certain risks. The cartman took the risk of damaging his hops with rain, and with small demand and also low prices. Many times they were forced to sell under price. This way of transport and the risks, were very expensive. The trip with horse-cart was long and the hop packed linen bags were very large.

At the beginning of l9th century the trade in hops was in the hands of a vast amount of merchants, Czech or foreign. Except for big merchants purchasing 700 - 1 000 "stricks" (till 1843 the hops were measured not weighted) the registers state that the amount of small merchants, who purchased 10 to 50 "stricks", waited for price increases and then again sold the hops.

In the middle of the l9th century there was a great change in hop trading. With the gradual arrival of the railway the hop merchants had to stop cart trading. After introduction of telephone and telegraf, communications spread more quickly. In autumn 1843 the hops were weighted in so called Vienna cents (56 kg) and verifing papers are introduced. From 1875 the decimal system was set and hops were weighted in custom's cents (50 kg). Mainly the railway meant the biggest step in hop trading. The transport reduced to 1/8 the price, it was faster and protected hops against climatic changes.

In the 60's of the l9th century the hop trading law became common. It was never passed officially but was consistently kept. It divided the merchants into 3 groups - local, commissars and experts. The local traders were specialised in purchasing hops from the producers. The commissars exchanged and delivered hops for a fee. From 1860 to 1879 there was a so called hop-market in Zatec. It was opened from October to December, on every Thursday. The main Hop-merked was opened from l5th to 31 st October daily. By the use of price and quality sorting were Zatec hops divided to town, district and region. The Market was well known for íts strict control of production, origin and quality. Each group of hops had its own attesting papers. The ballots were marked by the so called big seal of the Zatec Hopmarket.

At that time sales technique was definitely formed. During the 50 years  the means of sale changed from house to house sale to capitalistic based on the marked custom of the Bavarian business chamber. The amount of local merchants had decreased and the market was in the hands of less people. During the 70's there were 6 big companies, which took all the local trade and purchase and export. They originated mainly from the joining of house and local merchants. The first company was founded in 1866 by Martin Holy.

At the end of l9th century the Czech Hop-market was in the hands of german capital. Limited partnership company, which was first founded as the 1st czech business Hop company became the "First Czech Stock company in Rakovník and Zatec" in the year 1898.

Together with the change of sale came also other changes which are tied closely to the business. Operation on a railway from Prague to Chomutov started in 1871, in 1872 another railway was opened from Pilsner to Duchcov. At that time new transporting companies started operating, one of them, the largest was the company of Eduard Fanta, which also operated special railway carriages for hop transport.Increased market demands and higher quality also caused changes in the packing. Former linen used in packing ballots was replaced by jute.

Tin cylinders started to be used for better and longer storage in the 80's. Transport on sailing boats also brought up the need of storage of packed goods in tinned boxes. High duty stopped bigger expansion of these means of packing. Duty was payed for the whole weight and with cylinders the metal also.

The former measures protecting Czech hops proved inadequate and that is why a special institution for certification of the genuinesness of Zatec hops was established in Zatec in the year 1884. At that time hops were stored in cellars, where storage temperature was maintained by ice. Apart from the European continent, Zatec's hops were exported to Northern America, and in 1901 also to Japan. The main sea route went through Hamburg and a smaller amount through Triest.

Further ímprovement of legal protection of hops was achieved in the beginning of the 20th century. The dissension between towns, producers and sellers went so far, that for some time there were two certification institutions in the town - one was the town's and the other the growers. The town lived on hops. There were for example 53 packing stations in Zatec in the southern part of town. At that time there were 161 companies trading with hops. A few companies always used and shared one packing station. Verifying didn't occur in the packing station as it's done now, but hops were delivered to the certification building. The transport was made by a separate group of people, who formed a guild. All who had anything to do with hops were members of "Business trading company with hops and hop products in Zatec". This company associated all sellers of hops, hop products and comissions. The company had a forced membership. It's aim was to protect common interests and help in educating the economical programmes of its members.

Reguardless of this concentration of companies and capital, Zatec hop companies were also hit by the economic crisis in the 30's. Unmarketable hops were purchased by a Hop-syndicate which organized their liquidation. That was the worst time for Zatec hops. But soon it managed to rise again and became as important as before. Hop business also continued during the war but it wasn't that big. The old timers remember export of hops to America from Jugoslavia. The cargo was marked as "American property" and was followed by war ships.

After 1945 National control was established over the packing stations and small companies which didn't have their own packing station.Beside the Czech hop company there was a seperate plant "Cooperative of Hop Growers". Also there was the Agrasol company, Union for hops, malt and beer and Czech private shops with the hop-companies: Beranek - Kollman, Frantisek Kelner and Vojtechovsky.

After 1948 and nationalization of I packing stations was formed the Company foo purchasing and stocking hops. For export, the Czech company for hop export was founded. Later it became a part of the Koospol stock company. At that time Zatec hops were exported to 72 countries of the world. Technical progress also affected the way of hop exporting. For example on 16.9.1957 J.G. Bauer first used his truck for hop transport. In spite that this was an unusual way to solve transport problems, soon the trucks were used for normal transport. For safety of quaI lity, containers have been used in Zatec since 1977, mostly for transport to the USA and Japan.

Further development of breweries was that in 1973 hop pellet production started on assembly line type 90. Since then the amount of hops produced this way gradually increased, till it exceeded the capacity of the line. By the end of the 80's it was decided that a new place of business for pellet production with both types 90 and 45 lines  should be built.

Gradually some business companies and stock companies (a.s.), also Limited Companies (s.r.o.), arose, they purchase hops and after cultivating and packing in the Zatec cooperative company, they sell it to local breweries and export it abroad.

In the year 1992 the Union of Hop Traders was founded to protect the interests of particular business companies. It associates all hop business companies in the Czech - Republic.  

FORM OF PROCESSING OF HOPS

PRESSED HOPS

Hops from farmers are lightly pressed into farmers bales of about 65 kg and  10 - 11 % moisture, delivered to the processing plant with stem and leaf etc. separated, properly dried and pressed into the requsted shape in synthetic fabric. The weight of individual ballots is 100 - 175 kg.

 

PELLETS TYPE 90

Each lot of hops is analyzed for humidity and alpha contents, then put into the production line, where there are cleaned by magnets and by a stream of air, homogenized, dried up to the desired humidity, milled into powder, homogenized again and pelletized. During this process the temperature is never higher than 58° C and after the granulation pellets are immediately cooled to 20° C - 24° C. The temperature levels are continuously checked at several spots in the pelletizing process. Pellets are then put in 5-20 kg allubags, flushed with inert gas, either with pure Nitrogen (N2) or oxide carbonate (CO2) or with the mixture of both, then put into cartons, cartons on pallets. Bulk pack bags of 90 - 150 kg, are also available flushed with inert gas (either pure Nitrogen (N2) or oxide carbonate (C02)).
For bag packing the pallets 110 x 73 cm are used - optimal quantity loading into 20 feet container. For bulk sized packing pallets 120 x 80 cm are used.
The advantages of pellets are in transport cost, storage space, homogenity and easier dosage in brewing process.

PELLETS TYPE 45

Processing is the same as pellets type 90 except that the milling of the hops occurs below minus 35° C. Customers specif'ied concentrations are set and checked by computers. Packing see pellets 90.
The advantages of this product: Ideal possibility of easier and less expensive transportation and storage. Aroma and all the brewing value are well preserved. Exact and easier dosage in brewing process. Lower contents of nitrates and residua of heavy metals.
 

 

ZATEC SEMI-EARLY RED-BINE HOP

Hops are grown in many places in the world, but not all hop areas have the quality and special properties of the Zatec area. This proves that not only the vine variety, but also combination of natural conditions such as location, soil, climatic conditions contribute to optimize their quality. The tradition of thousand years of hop growing has a substantial effect as well.
    The uniqueness of the Czech Saaz Hops is given by specific natural conditions, especially in the Saaz Area. This area is protected from northwest by Krušné Mountains, Doupov Hills and Czech Mountains, which create so-called rainshade. The yearly precipitation in average is only 450 mm but spread at the same time very favorably to the growth of hops. The average year temperature is 7,5° - 8,5° C. Together with the natural and climatic conditions the soil has a considerable influence on hop quality. There are mainly permian red soils and light drift soils a specific feature of this hop area. The proper development of hop plants is also influenced by the location of hop gardens altitude, location in terrain relief, its slanting and relation to the cardinal points.
    Inside of each hop area there are thus some areas particularly suitable for hop growing i.e. where first class quality hops are produced: wide open valleys with the free air streaming, well protected against the strong west and north winds. Inside Saaz area the best locations are Golden Creek Valley (Údolí zlatého potoka) and Woodland (Podlesí). In Auscha Area Polepy Marshland (Polepská blata).
    The basic quality is, naturally, given by the properties of the "Zatecký poloraný èerveòák" variety (Zatec semi-early red-bine hops). This is a variety with an exceptionally healthy base and genetic purity. The specific characteristics of Zatec hops are the fineness, perfect appearance, fine genuine hop aroma and golden colour, designating the ripeness and health of the hops.
    In a year of normal harvest, Zatec hops contain about 14 - 15 % of soft resins and about 4 % alpha-acid. From the brewer's point of view not only the resins, but also other components, especially tannins and essential oils contribute to the quality of beer.
    Apart from alpha bitter acid there is a very important betafraction in Saaz Hops. This fraction is more marked in Zatec hops than in other hops (1,5 : 1). The results of our own and foreign scientific experiments prove that a larger part of the B-fraction changes by boiling into a soluble form. From tests conducted follows that the higher proportion of the B-fraction in Zatec hops has a significant influence on the typical fineness and pleasant bitterness of beer.
    The most characteristic feature of the Zatec semi-early redbine hops is of course its aroma. Saaz Hop aroma is unique, mild hop aroma, typical for this variety. The chemical analysis confirms again its typical composition: One of the assets compared to other hop varieties - could be considered a low content of myrcene and on the other hand higher content of farnesene.
    The importance of tannins should not be forgotten, too. Saaz Hops has a higher contents of tannins than any other hops. The overall character of Saaz Hops aroma is then given by the relation of all components.
Owing to these properties, i.e. their capacity to impart to beer a fine aroma and a pleasant bitterness, Zatec Hops are used by almost all important breweries at least for the last hopping.   
    Consumers do not wish to see in beer only a means of quenching thirst, but an important and pleasant nourishing product which moreever furthers digestion and healthy sleep. Beers from Zatec hops are intended for the most demanding customers - many breweries are indebted to them for popularity of their beers.
    A virus free hops programme started a few years ago and from 1994 virus free plants are grown on a number of hop gardens. Virus free Meristem roots have been produced by well known methods such as thermotherapy and imunnoenzymatic detection for individual viruses.
    The results after 7 years: the average yield is higher by 28 %, the average alpha acid is higher by 48 %. Chemical analysis of the hop's essential oils and resins confirm that the virus free hops have retained the quality of Saaz fine aromatic hops.
