PROVISIONAL SPECIFICATION.
Improved Preparations to be used in Brewing, and in the Treatment
of Finished Beer.
I, AUBREY FREDERICK SPENCER of 20 Montpelier Crescent, Brighton in the
County of Sussex, Analytical Chemist and Brewer do hereby declare the nature of
his invention to be as follows:-
The invention consists principally of a novel compound or preparation to be
added to the wort in the copper or in other stages of the brewing operations
whereby the beer will be improved in three ways namely, first the compound will
take the place of a portion of the hops usually employed, second the beer will be
preserved and third nourishment will be furnished to the yeast in the fermentation.
This novel compound or preparation contains in one gallon the following
inaterials in about the proportions stated: 1344 ounces of sulphite of soda
solution 25-6 ounces of extract prepared by macerating the powdered leaves of the
piptocalya moorci with a mixture of alcohol and water and in the gallon so far
prepared are dissolved 4 ounces of borax, 320 grains of phosphate of potash,
55-2 grains of sulphate of sodium and 44.8 grains of sulphate of magnesia.
The proportion of sulphite of soda and borax may be increased according to
requirements.
By adding the above compound or preparation to the wort in the copper or in
the mash tun in the proportion of a half pint of the compound or preparation to a
barrel of finished beer a portion of the hops ordinarily employed is replaced by the
piptocalyx extract, the beer will be preserved by the sulphite of soda and borax and
the phosphate of potash, sulphate of sodium and sulphate of magnesia dissolved in
the compound or preparation will furnish nourishment to the yeast in the
fermentation.
If desired the proportions of the yeast food may be increased.
Instead of employing the above ingredients in a single or combined preparation
they may be used in three separate solutions or preparations, namely the "piptocalyx
extract as a substitute for part of the hops ordinarily employed, the solution of
sulphite of soda and borax as a preservative, and the solution of phosphate of
potash, sulphate of sodium and sulphate of magnesia as a yeast food and when
employing the first and last of said preparations separately from each other and
from the piptocalyx extract I combine with each of them a suitable proportion say
from two per cent. and upwards of sulphite of soda and borax to preserve said
preparations.
The piptocalyx extract and the sulphite of soda and borax solution may also be
added advantageously to finished beer.
The proportions of the various ingredients may be modified as may be required.

Improved Preparations to be used in Brewing, and in the Treatment
of Finished Boor.
I, AUBREY FREDERICK SPENCER, of 20 Montpelier Crescent, Brighton, in the
County of Sussex, Analytical Chemist and Brewer, do hereby declare the nature
of this invention, and in what manuer the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
The invention consists principally of a novel compound or preparation to be
added to the wort in the copper, or in other stages of the brewing operations,
whereby the beer will be improved in three ways, namely, first, the compound will
take the place of a portion of the hops usually employed, second, the beer will be
preserved, and, third, nourishment will be furnished to the yeast in the
fermentation.

This novel compound or preparation contains, in one gallon, the following
materials in about the proportions stated:-1344 ounces of sulphite of soda
solution, 256 ounces of extract prepared by macerating the powdered leaves of the
pipturalyr moor (see Bentham's Flora Australiensis," vol. V., p. 292,) with
a mixture of alcohol and water, and in the gallon so far prepared, are dissolved
4 onnees of borax, or preferably boracic acid, 320 grains of phosphate of potash,
552 grains of sulphate of sodium, and 448 grains of sulphate of magnesin.
The sulphite of sodium solution employed contains 8 per cent." of sulphite of
sodium or thereabouts.
The pipocalyx extract above referred to is prepared by macerating the powdered
leaves with a mixture of alcohol (spirits of wine) and water, and the strength is
such that from a pound of leaves in powder, a pound of extract is produced. The
percentage of solid matter in the extract thus prepared is 135 per cent.
Phosphate of suda may be substituted for the phosphate of potash above
referred to.
The proportion of sulphite of soda and borax or borncie arid may be increased
according to requirements.
By adding the above compound or preparation to the wort in the copper or in
the mash tun in the proportion of a half piut of the compound or preparation to a
barrel of finished beer, a portion of the hops ordinarily employed is replaced by the
piptocalyx extract, the beer will be preserved by the sulphite of soda and borax or
borneie neid, and the phosphate of potash or soda, sulphate of sodium and sulphate
of magnesin dissolved in the compound or preparation will furnish nourishment to
the yeast in the fermentation.
If desired the proportions of the yeast food may be increased.
་་
Instead of employing the above ingredients in a single or combined preparation,
they may be used in three separate solutions or preparations, namely, the
piptocalyx extract as a substitute for part of the hops ordinarily employed, the
solution of sulphite of soda and borax or bornoic acid as a preservative, and
the solution of phosphate of soda or potash, sulphate of sodium and sulphate of
magnesin, as a yeast, food, and when employing the first and last of said preparations
separately from each other, I combine with each of them a suitable proportion, say.
from two per cent, and upwards, of sulphite of soda and borax or boracic acid in
preserve said preparations.
The preparations containing phosphate should be used before fermentation and
preferably in the copper.
The piptocalyx extract and the sulphite of soda and borax or boracic acid
solution niny also be added advantageously to finished beer.
The proportions of the various ingredients may be modified as may be required,

page_text: 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
clain is:-
:-
1. The novel compound or preparation consisting of sulphite of soda solution,
extract of piptocalyx moorei, borax or boracic acid, phosphate of potash or soda,
sulphate of sodium and sulphate of magnesia, to be used in brewing before
fermentation and preferably in the copper, substantially as herein described and for
the purpose stated.
2. The novel compound or preparation consisting of the extract of piptocaly.r
moorei, sulphite of soda solution and borax or boracic acid, to be used in brewing
and in the treatment of finished beer, substantially as herein described and for the
purpose stated.
3. The novel compound or preparation consisting of the solution of sulphite of
soda and borax or boracic acid to be used in brewing and in the treatment of
finished beer, substantially as herein described and for the purpose stated.
4. The novel compound or preparation consisting of the solution of phosphate
f potash or soda, sulphate of sodium, sulphate of magnesia, sulphite of soda and
