Our tour begins with the "Seven Essential To Success" in the Brewing, Bottling and Distribution of high-class Ales and stouts. These - Davenports believed - are the following:
1.
Pure water
2. Best Quality Materials
3. Good Yeast
4. Efficient arrangement and equipment of Brewery and bottler
5. Cleanliness
6. Efficiency of office and transport organisation
7. Service
...
and continues:
The attainment of perfection in these seven essentials has
been our constant aim for fifty years, and during that time we have spared
neither
energy nor expense in our efforts to attain the results which we now propose to
describe under the seven appropriate headings.

Davenports
insisted that the most important of all factors in good brewing was a
constant supply of pure water; without this all other considerations
became secondary.
A borehole some 700 feet (213.36 meters) deep, and taking five years to sink,
was taken down through several water strata until pure water was struck. Iron
tubes weighing over ten tons were then lowered into the pure water and liquid
concrete pumped into the hole to make a perfect seal.
This effort was rewarded by the granting of this Testimony of Purity:
It was dated 12 October 1928, and reads:
Dear Sir
Samples of water collected from your two deep artesian wells,
designated "Brewery Well" and "C. B. Well" respectively,
Have been submitted
to
a complete bacteriological examination.
I have to report that these waters are of an exceptionally high order of purity
by the
standards adopted for drinking waters.
Yours faithfully
C. J. Lewis BSc. M.A.
Together with the water, only Malt, Hops, and Sugar were used to make the beer.
MALT
Davenport's
barely-malt was specially made under licence [seemingly by several companies]
and stored on their premises until required. It was stored
with great care, immune from any trace of damp. Once delivered to the brewery
it would be kept with the same care in a specially built insulated
chamber at a constant temperature of 85 degrees Fahrenheit (29.4 degrees
Celsius).



When
the souvenir book was published in 1935, the Transport Fleet consisted
of
"... 140 motor lorries of varying sizes".
Each year that fleet carried approximately
90,000 tons of goods from the premises and returned 60,000 tons of empty
bottles and cases.
The distance traveled by the lorries in that year was
a little over 1,500,000,000 miles, equivalent to sixty journeys around
the earth at the Equator.
The brewery had, at that time, 175,000 regular customers.
