We'll start with some general remarks about the beers entered. Beginning with those fancily-labelled beers.
One of the first points to be noted at the exhibition was the pains expended abroad in making bottled beers attractive to the eye by choosing the most tasteful bottles and labels. It will not be invidious to state that the beers of the United States of America stood out prominently in this connection, whilst the Russian and Japanese samples deserve the highest praise for their artistic get-up.

Most UK labels were pretty functional back then. With little more in terms of graphic design than the company's logo. Like Bass and their red triangle. Mostly, iy was just text.
There had been a revolution in brewing outside Europe with the development of artificial refrigeration. Which made brewing possible anywhere in the world, no matter what the climate. My experiences in brew houses in Brazil, where I felt like I was about to collapse from heatstroke, demonstrate how difficult brewing there would be without refrigeration.
The adoption of scientific methods of brewing has rendered possible the production of beers in countries where the climate is by no means propitious, so that those who have taken up their abode in tropical countries need no longer be deprived of the luxury of malt liquors except at prohibitive prices. Indeed, the establishment of breweries would seem to proceed hand in hand with the spread of civilisation, and to-day some type of beer is produced practically all over the world.
Bearing in mind the conditions obtaining in some of the countries from whence the beers emanated, and taking into account the distance they had to be sent, it would not have been surprising had many of the samples arrived in an undrinkable condition; yet such was not the case, and among the whole collection tasted not one of the beers could be described as actually unsound.

There were drawbacks to these new cold-fermented beers. Without cooling, they quickly spoiled.
Bottom-fermentation beers must of necessity be brewed under what may be described as artificial conditions (low temperature), so that the difficulties of local environment are in a sense minimised. On the other hand, it must be remembered that these bottom-fermentation beers are less able to withstand disease when exposed to ordinary temperatures for lengthened periods than are top-fermentation beers. It is, therefore, the more to the credit of those who produced them, even bearing in mind that they were all bottled samples, that they stood the transport so well. But most of the samples from India, Canada, Australia, and New Zealand were top-fermentation beers, and although these differed from the English product, being more of the Lager type in character, the majority were of very excellent quality, and none of them could be described as undrinkable.

It's interesting the colonial top-fermenting beers were Lager-like in character. What is exactly meant by that? A lack of fruity esters? A high dextrine content?
Finally, a note on the system of marking.
In making the awards, beers of similar types and from the same countries were placed in competition. This was the only practical course since the products of different countries differ so markedly. The beers have been awarded three, two, and one marks respectively in their order of merit; but these marks have a purely relative value, and it must not be concluded that two samples from different countries to which equal marks have been given are of equal excellence, even sui generis. In some cases the type of beer differed so greatly from anything we were previously acquainted with, that comparison was a difficult matter.

No style guidelines, then. Just comparing like with like, as for style and origin. Seems fair enough to me.
