Growing hops in Egypt (part one)

I was quite surprised to find a report about growing hops in Egypt early in the 20th century.

From what little I know about the growing of hops, they require very specific climatic conditions. One of which is the length of daylight in the summer. Which, in the northern hemisphere, means that there's a limit to how far south hops can be grown. And the limit is much further north than the southern coast of the Mediterranean. Meaning growing hops in Egypt was never going to work.

The Cultivation of Hops in Egypt.
Some years ago we drew attention to the fact that Mr. C. Howard Tripp, managing director to Messrs. Ind, Coope and Co., of Burton-on-Trent and Romford, was endeavouring to start the cultivation of hops in Egypt. The matter was taken well in hand, and, through the kindness of Dr. Mackenzie, the Principal of the School of Agriculture at Ghizeh, near Cairo, three-quarters of an acre of Government land was reserved for making a trial. Mr. Tripp has twice visited Egypt during the last few years, and, on each occasion, thoroughly inspected the hops; they were not sufficiently advanced, nor did there seem to be much prospect of success. The matter has, however, recently been again brought under Mr. Tripp’s notice, and, at his request. Dr. Mackenzie instructed his assistant, Mr. Linton — who is in charge of the hop cultivation at the School of Agriculture above mentioned — to make an exhaustive report on the whole subject.

The Trade has every reason to be grateful for this disinterested enterprise which Mr. Tripp has undertaken, and our readers will be glad to learn that he is nothing daunted by the want of success which has, up to the present, attended the scheme. He has now suggested to Dr. Mackenzie that as the English hop sets, Essex, Worcesters, East Kents, Wealds, have all more or less failed to withstand the trying July heat referred to in the report, Californian hops might, perhaps, prove better adapted to these conditions. Mr. Tripp purposes, therefore, sending Dr. Mackenzie, during this autumn, from California, a quantity of hop sets. It would unquestionably be a great assistance to the trade if it were possible to grow a large quantity of hops, even of the Californian type, in Egypt. No crop is more insidious than the hop, and the shortage of the present season brings this prominently to the minds of brewers. la order that our readers may see for themselves how very thoroughly these interesting experiments have been carried out, we give below in extense the report on the subject already mentioned. If it be found possible to make the necessary arrangements a trial may be made in the neighbourhood of Alexandria, where during the summer the atmosphere is moister and the temperature lower than at Ghizeh.

For anyone brewing in Egypt, locally-grown hops would have been dead handy. Plenty of barley was grown in the Middle East and hops would have been the only ingredient which would have needed to be imported.

I'm not surprised that English hop varieties struggled in the heat of the Egyptian summer. Though, given the daylight requirements of hops, American varieties weren't going to fare much better. Making any attempt at growing hops in Egypt futile. I wonder when they realised how much daylight hops required?
