PROVISIONAL SPECIFICATION.
Manufacture of Material for Use in Brewing or Priming Ales
and Beers.
I, BASIL WILLIAM VALENTIN, of Bryn-Mair, Llanelly, in the County of
Caermarthen, Brewer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to the treatment of malt extract or malt sugar so as to
obtain a material for use in brewing or priming ales and beers. For this purpose,
I make an extract containing malt sugars, that is to say dextrin and maltose (or
the so called malto-dextrins) by conversion of starch with diastase or acid,
conducting this conversion so as to leave a very large proportion of free dextrin.
This extract is purified by filtration through animal charcoal, and is then
concentrated, it may be, in vacuo. It is next submitted to a prolonged melting in
pans provided with stirrers, until it becomes to some extent caramelized. In this
manner I obtain a sugar containing maltose and dextrin, the former being in a
condition in which it is only fermentable with difficulty, while the dextrin, which
is in large proportion, is entirely unfermentable during the primary fermentation
of the wort.
It is well known that, by prolonged boiling of malt wort, certain caramelized
substances are produced which impart great palate fulness to beers; by treating
malt sugar as above described I produce these substances in a concentrated form
suitable for being added to the beer. The saccharine matter, thus added to the
finished beer, is slowly fermented under the influence of cask yeasts, and thus
gives continuous life or condition to the beer, adding at the same time great
palate fulness.
The material produced as above described is also very valuable as a priming to
be added to the finished beer.

I, BASIL WILLIAM VALENTIN, of Bryn-Mair, Llanelly, in the County of

manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-

It is well known that by high temperatures on the malt kiln or by prolonged
boiling of malt wort, certain caramelized substances are produced which impart
great palate fulness to beers; by treating malt sugar as above described, I produce
these substances in a concentrated form suitable for being added to the beer. The

The material produced as above described is also very valuable as a priming to
be added to the finished beer.
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 :-
1. The herein described process for producing a sugar containing maltose and
dextrin and applicable in brewing or as priming for ales and beers.
2. The maltose and dextrin compound manufactured as above set forth.
