SUGAR POUNDING,
AND
GENERAL GRINDINC
MACPHERSON STREET, GLASGOW.
f 9
The only Steam-power Roasting Establishment connected with the Trade in the City.
DMINTO begs leave to return thanks to the Grocers and Druggists of this town and vicinity for past t
• favours.
He also begs to intimate, that in connection with his Coffee- Roasting, and Coffee and Spice- Grinding
Works, he has fitted up an extensive Sugar-Pounding Machine, offering to the Confectioners and Trade in:
general an advantageous opportunity of having their Sugar Pounded by Steam-power, far surpassing
anything ever yet offered to the Trade.
P.S. — All Orders punctually attended to, and delivered by his Vans at the proper time.
Macpherson Street,
Glasgow, May, 1866.
The Coffee Plant, " Coffea Arabica'" of Linnaeus, is an evergreen, and, as may be inferred from its
scientific name, is a native of Arabia. It produces a pulpy berry about the Size of a small cherry, inclosing
two seeds, which, separated from their pulpy envelope, form the well known Coffee Beans of Commerce. It
may be remarked, as a singular fact in reference to Coffee, that while all of the vegetable kingdom that have
been taken under the care of man have been improved, it alone asserts its independence ; for, although
cultivation may greatly enlarge the crop, it as certainly, at the same time, deteriorates the flavour, "and the
produce of the wild plant still maintains the highest figure in the market. It is well known that Coffee
would be of no real value were it not properly roasted — a process which, as it requires much skill, is only
to be acquired by experience. How man became acquainted with the fact, that the tasteless seeds of a
berry, when roasted, ground, and infused, would form a grateful beverage, will most probably remain a
secret to the end of time. That the developement of its useful properties depends wholly upon the roasting,
is evident. About two hundred years ago Coffee was first introduced into England, since which its con-
sumption has steadily increased, and deservedly so, when its medical properties are considered, it having
been found useful in headaches arising from a particular state of the stomach, and much benefit having been
derived from its exhibition in cases of asthma.
A French scientific gentleman, who has directed his attention to this subject says : — I have found that
Coffee is better roasted, and more of the aroma retained, when a double cylinder is used — the air between
the interior and exterior cylinders acting as a non-conductor of heat. It is done more uniformly, while the
essential oil on which the aroma depends is less liable to be dispersed, than when exposed to the fierce heat
of a fire in a single cylinder."
In the double rotatory globular method of roasting as practised at Mr. Minto's Works, Macpherson
Street, Glasgow, the above principle is acted upon, inasmuch as the globe (which has superseded the
cylinder since the application of steam-power to this branch) revolves in a medium of heated air, which,
experience has shown, best prevents the dispersion of the essential oil, or aroma.
