Improvements in the Method of Treating Beer for Export and in
Barrels for the same.
I ARTHUR HOLLE of Muenchen in the Kingdom of Bavaria, brewery manager,
do hereby declare the nature of this invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
"
The object of my invention is to render beer which is intended for export to hot
countries or transoceanic shipment and has previously to be subjected to a
pasteurising" process capable of being exported safely and cheaply in the same
vessels in which it has been subjected to the pasteurising process and in large vessels
instead of having to be exported in bottles as ordinarily done. For this purpose I
employ metal barrels suitably prepared in the manner hereinafter described so that no
metallic taste is imparted to the beer or the latter spoilt by entering into combination
with the metal. The use of metal barrels serves to accelerate the pasteurising process
as metals are good heat conductors.
The barrels are made by preference of good charcoal sheet iron and are cheaply
prepared on their insides in the following manner: the inside of the barrel while open
at one end is carefully painted with tasteless iron lacquer as usually employed for
cooling vats or cisterns and after the first coat is dried, receives a second coat of paint
upon which while it is still moist silk or tissue paper is smoothly laid. The latter
then is also coated with a coat of lacquer. In this way a kind of paper barrel is
formed with an iron envelope and the beer prevented coming into contact with the
iron.
After the lacquered and papered barrel has been sufficiently exposed to the air
for deodorisation the bottom prepared in a similar manner is soldered on and the barrel
rinsed with concentrated beer. After being tested by hydraulic pressure the barrel
is filled and its contents subjected to the pasteurising process..
In order to protect the beer as much as possible against sudden changes of
temperature during transport, the barrel is surrounded by an envelope or cover
consisting of a bad heat conductor, for instance a coffee bag. Instead of the paper
lining the barrel may be lined with a metal not oxidised or attacked by beer, for
instance with nickel, but the paper lining is preferable on account of its cheapness.

page_text: The use of barrels made as hereinbefore described renders it possible to export beer
to hot countries in large vessels where otherwise it can only be exported to in bottles,
and greatly facilitates such export, as independently of the circumstance that the metal
barrels can be continually used over again for the same purpose, the volume and
weight of the packages in proportion to the volume of beer is reduced to a minimum
in comparison with the usual export in bottles, the cost of packing is materially less
and the losses through breakages are obviated.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is,
Firstly, treating beer for the purpose of rendering it capable of being exported in
the same metal vessels in which it is subsequently exported.
Secondly, the use of metal barrels prepared as hereinbefore described for the
pasteurising and export of beer, substantially as hereinbefore described.
Thirdly, the manufacture of metal beer barrels lined with lacquer and paper or
with a layer of non-oxydising metal so as to prevent contact of the metal of the
barrel with its contents; substantially as herein before described and for the purpose
set forth.
