Berlin Germany "AN IMPROVED METHOD OF PREPARING COFFEE IN A SOLID
FORM (A Communication from Eugen Geist of Munich Bavaria)
"
The object of this invention is to prepare coffee in the form of a compressed
cake or block which may be rendered suitable for drinking by being dissolved by
boiling in water or which may be eaten in the solid form.
For this purpose the roasted and finely ground coffee alone or mixed with finely
ground figs or other substitute for coffee is placed in a warm concentrated solution
of sugar in syrup and kept warm while constantly stirring until the sugar begins
to get stiff. The mass is then put into moulds and compressed and then left
to cool.
To produce a more flavoured article the process is as follows: 15 parts of white
powdered sugar are dissolved in cold water and boiled while adding 15 parts of
golden syrup until the liquid sugar becomes stringy. When this consistency has
been obtained, 55 parts of finely ground coffee are introduced into the sugar mixed
with 15 parts of roasted and also finely ground figs; the sugar encloses the coffee
particles and prevents the escape of the aroma. The mass is then while stirring
kept over the fire until the sugar begins to get stiff. When the whole mass has

frame divided into square or other fields, shaken, rolled with a glass roller and
subjected to pressure in a press.
The mass under the press is continually heated while slowly causing the press
follower to descend or follow up so that it is rendered close and compact without
loss of aroma. When the pressing is finished the frame is removed from the press,
the coffee tablets are cut, packed in tinfoil or parchment paper and are then ready
for transport and use. The coffee may of course be pressed into other forms than
tablets.
In using the prepared coffee a suitable quantity of it is put into boiling water
boiled a few minutes and then allowed to stand till the grounds have settled.
In the manufacture of this prepared coffee condensed milk may also be added.
It may be eaten raw and thus offers great advantages to travellers and tourists.
By the aforesaid process the coffee entirely retains its aroma and when packed
keeps very long.

The mass under the press is continually heated while slowly causing the press

the coffee tablets are cut, packed in tin foil or parchment paper and are then ready

By the aforseaid process the coffee entirely retains its aroma and when packed
keeps very long.
I claim as the invention communicated to me,
The production of coffee in the form of a compressed cake or block by mixing
burnt and finely ground coffee (with or without admixture of burnt and finely
ground figs or other coffee substitutes) with a warm concentrated solution of sugar
in syrup and if desired with condensed milk, heating the mixture continuously
until the sugar becomes stiff, and compressing the so obtained mass, all substantially
in the manner herein before described.
In Witness whereof I the said Gerard Wenzeslaus von Nawrocki have
bereunto set my hand and seal this Thirtieth day of October in the year of
our Lord one thousand eight hundred and eighty-two.
