AN IMPROVEMENT IN THE MANUFACTURE OF BEER
Year: 1874

page_text: LETTERS PATENT to Alexander Melville Clark, of 53, Chancery Lane,
in the County of Middlesex, Patent Agent, for the Invention of
"AN IMPROVEMENT IN THE MANUFACTURE OF BEER."-A communication
from abroad by Jules Louis Tröster, of Paris, France.
PROVISIONAL SPECIFICATION left by the said Alexander Melvillo
Clark at the Office of the Commissioners of Patents, with his
Petition, on the 13th May 1874.
I, ALEXANDER MELVILLE CLARK, of 53, Chancery Lane, in the County
of Middlesex, Patent Agent, do hereby declare the nature of the said
Invention for "AN IMPROVEMENT IN THE MANUFACTURE OF BEER," to be as.
follows:-
This Invention relates to a new product; viz., beer, concentrated to
any desired degree, and even rendered solid if desired in order to facilitate
transport and exportation,

page_text: By the process of this Invention every kind of beer may be con-
centrated to a pasty or a solid state, in which condition it is not liable
to fermentation, any may be enclosed in metallic cases for transport in
all climates.
In order that the Invention may be more readily understood, I will
describe it in reference to what is known as <<
Strasburg "beer for the
sake of example. To make 220 galls. of the above beer, from 7 to
8 cwts. of malt are employed, and about 16 or 17 lbs. of hops, according
to the quality desired.
Now in order to obtain by this Invention a concentrated product which
will furnish 220 galls. of beer, I employ about 2½ cwts. of malt, that is
to say, only about one-third the quantity ordinarily used to the same
amount of hops. With these materials I obtain by a process analogous
to that of ordinary brewing (but employing only one half the usual
quantity of water) a product which is half the bulk only of that usually
obtained. I then place this concentrated product in a boiler (adding
sugar in proper proportion to suit the strength of beer required) and
reduce it to /ths., the product obtained being what I term concentrated
beer.
The chief object of the Invention is to dispense with the alcoholiza-
tion of beer, to render it capable of undergoing a sea voyage, and also to
save the
expense of transporting a quantity of liquid, and to avoid waste
from leakage and other causes.
The concentrated beer thus made may be converted into a liquid and
drinkable condition as required, in the following manner :-)
-To produce
220 galls. of beer about-220 lbs. are dissolved in water, which will
require about 24 hours. Ordinary yeast is then added in proper pro-
portion. In this manner five days will be sufficient to convert the
concentrated matter into a beer in all respects similar to the " Stras-
burg" beer, taken as an example.
It will be understood that other well known beers may be similarly
obtained in a concentrated form.
It will also be seen that the yeast is separate from the concentrated
beer, which is a distinctive feature of this Invention.
This concentrated beer may be made in the form of cakes, tablets, or
otherwise moulded, or the yeast or ferment may be also concentrated.

filed by, the said Alexander Melville Clark in the Great Seal Patent
Office on the 12th November 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALEXANDER
MELVILLE CLARK, of 53, Cliancery Lane, in the County of Middlesex,
Patent Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirteenth day of May, in the year of
our Lord One thousand eight hundred and seventy-four, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Alexander Melville Clark, Her special
licence, that I, the said Alexander Melville Clark, my executors,
administrators, and assigns, or such others as I, the said Alexander
Melville Clark, my exccutors, administrators, and assigns, should at
any time agree with, and no others, from time to time and at all times
thereafter during the term therein expressed, should and lawfully might
make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and. Isle of Man, an In-
vention for "AN IMPROVEMENT IN THE MANUFACTURE OF BEER," a communi-
cation to me from abroad by Jules Louis Tröster, of Paris, France,
upon the condition (amongst others) that I, the said Alexander Melville
Clark, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and seals, should particularly
describe and ascertain the nature of the said Invention, and in what
manner the same was to be performed, and cause the same to be
filed in the Great Seal Patent Office within six calendar months.next
and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Alexander Melville Clark, do
hereby declare the nature of the said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained
in and by the following statement, that is to say :-
This Invention has for its object to provide a means or method of so
concentrating or consolidating the ingredients or component parts of
beer, ale, or other malt liquors, as to reduce the volume thereof to the.
smallest possible proportion, and by giving to the concentrated or con-,
solidated mass a compact shape, permit of its being casily conveyed from

page_text: process I produce any other kind or description of malt liquor from wort
concentrated or consolidated in the manner herein-before described.
In order to render the Invention more generally applicable in all
cases in which it is desirable to have the necessary materials ready at
hand for producing beer in large or in small quantities, or else to have a
substance possessed of all the properties and virtues of beer without
being in the form of a liquid, I do not confine myself to giving the
concentrated or consolidated wort any particular shape or producing it
in masses of any particular volume, but I reserve to myself the power
of moulding it in such proportions as may be suitable to prepare there-
from any quantity of malt liquor, such as a gallon, a pint, a bottle of
beer, or any other measure that may be required.
With a view to obtain a product convertible into malt liquor by
means of a direct and simple process of solution Ì cover a unit of
ferment corresponding to a pint, a quart, a bottle, or any other quantity
of malt liquor, with a layer or coating of gum, gelatine, or any other
soluble integument, and around this unite of ferment thus coated, as a
core or nucleus, I place or mould a corresponding unit of wort prepared
in accordance with the process of this Invention, and enclose the whole
mass in a coating or layer of soluble material. By this means I am
enabled to produce a unit of malt liquour, say a quart, a pint, or a bottle
of beer by dissolving the mass in a suitable vessel, and allowing it
therein to go through the process of fermentation.
By moulding the mass of concentrated or consolidated wort along
with the nucleus of ferment into lozenges, or giving it any other of the
popular portable shapes, I obtain a product possessed of all the qualities
of beer, but being solid instead of liquid, and suitable for consumption
on a journey and for other cognate purposes.
Having described the nature of the Invention and the manner of per-
forming the same, I declare that I claim as the Invention to be pro-
tected by the herein-before in part recited Letters Patent is,-.
1st. The production of concentrated or consolidated wort, either
solidified or in the form of a paste, by means of a process of evaporation,
substantially as herein-before described.
2ndly. Moulding the concentrated or consolidated wort, as prepared
in accordance with this Invention, with or without a core or nucleus of

page_text: ferment, in lozenges or other suitable shapes, in the manner herein-before
described.
In witness whereof, I, the said Alexander Melville Clark, have
hereunto set my hand and seal, this Twelfth day of November,
in the year of our Lord One thousand eight hundred and seventy-
four.
Witness,
HY. SWALES,
