GRAY'S INN WINE ESTABLISH—
AIENT, No. 23, HIGH HOLBORN, LONDON.
After ten years' experience, the Proprietors of the Gray's
Inn Wine Establishment have the satisfaction of knowing that
the liberalized spirit of enterprise with which they commenced
business has accomplished the object they hoped to obtain—the
continually increasing confidence and patronage of the public.
It was seen that, while enlightened principles and improved
systems of business were being extended to almostevery branch
of commerce, the WINE and SPIRIT TRADE partook of
little of those advantages—the consumers in many instanees
being supplied from small dealers, who frequently, from acci-
dental or necessitous circumstances, were thrown into the wine
trade without the slightest claim to a knowledge of its princi-
ples, possessing little or no capital, generally the most incom-
Potent judges of the articles they profess to understand ; and,
from all these causes, perfectly unable to protect the interests
Insd health of their customers. Thus a wide field was open for
bell-directed capital and exertion.
The Proprietors associated themselves with a gentleman edu-
cated from his youth upwards into a full knowledge and ac-
quaintance with every department of their business, embarked
a large capital, opened direct communications, and ultimately
established intimate relations with the wine growers and 4iip-
Pers of all countries, thereby placing themselves in the most
favourable position to take advantage of both the Home and
Foreign 'Markets. They have always sold at a fixed and mode-
rato profit, which, together with their increasing desire to gra-
tify both the tastes and wishes of their friends, has enabled
lllem to succeed in raising their Establishment to its present
eminence.
The Bonded, as well as the Duty-paid Stock, embraces every
variety of Wine, from the most economical up to the highest
possible quality. Gentlemen who prefer it can make their se-
leetion of Pipes, Hogsheads, or Quarter-Casks, in the Docks.
Ip the Duty-paid Stock there are always from Forty to Fifty
pipes of Wine on Draught, of which any quantities may be
L "ad• The Bottled Stock contains from Five to Six Thousand
siozen of Port Wine of the best Vintages, from two to ten
/cars in bottle; the whole at the lowest prices consistent with
the quality offered.
The most various and most curious of the Sherries shipped
so,rsnt.le Lay of Cadiz are to be found in their possession, and
e
winea rich treat to the Connoisseur in really Pure and Virgin
The Proprietors, in returning their best thanks to the Public
the constantly-increasing encouragement their exertiens
met with, beg to add, that their Business will continue,
4lt has continued since the Ist January, 1834, under the di-
rection of Mr. Kislingbury, the Managing Partner; and their
!latitude will stimulate them still further, if possible, to de-
serve its entire confidence.
