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.
