The treading-out process occupied forty-eight hours, and I was heartily glad when it was over. Either the Hadji or I was present all the time, to see that the work was thoroughly done, and that no water, under any pretext, was brought to the scene of operations. The slightest moisture spoils the wine. The bunches were sorted as they were taken from the lodahs; all the unripe or rotten grapes, of which there were very few, removed; and the examined bunches were then thrown under the feet of the treaders. When each pan was thoroughly trodden its contents were carefully gone over, to see that there were no unbroken grapes. Those that were discovered were crushed at once by the fingers, and then the panful was emptied into the jar.
The “Cholar” grape is generally white, very few black vines being found. These grapes, being grown on terraces on the mountains, cannot be irrigated; hence the keeping properties of the wine. Probably no other wine would keep, made in such a hot climate as Shiraz is, more than the year. That from the Cholar grape never goes bad. The grape is quite globular, and the size of a large marble-taw; they cannot be mistaken for any other kind. They are not nice for eating, having a harsh skin and many stones.
At last all the grapes being crushed and in the jars, or kumrahs, as they are called, the room was carefully swept out again and the door locked. Fermentation had already commenced, as a slight crackling noise could be heard from the jars that had been filled first.
The Hadji now prepared three plungers of wood. Each was made like what laundresses call a copper-stick, but had at the extremity four blades of thin plank at right angles to the stick, about six inches long and two broad. These were for thoroughly mixing and working up the mass of husks, stalks, and juice.
On going to the wine-room fifty-six hours after the process had been commenced, the six first jars were found sufficiently progressed to proceed with. The grapes and husks had come to the surface and formed a compact cake, which floated on the fermenting juice, and nearly touched the lid. A buzzing noise came from most of the jars, caused by the bursting of innumerable small bubbles, and the temperature of the room was considerably raised by the heat evolved.
The Hadji drew my attention to the fact that the jars were getting hot, which was satisfactory, showing that fermentation had thoroughly set in. With the plunger he now thrust the cake of crushed grapes, etc., that had formed on the four first jars, to the bottom, and a considerable escape of gas ensued. The plunger was spun round in the liquor with both hands, and the contents of the jar thoroughly mixed, the cloth and cover were replaced, and the door locked.
In four hours’ time the process had to be repeated on eleven more jars and the four original ones. Again in three hours’ time a fresh visit had to be made, and these had to be more and more frequent. Thus great attention was required, for as the room got warmer, from the heat evolved by the fermenting juice, so did the fermentation increase in violence. In some jars it was very furious, and from these the Hadji removed the rushwork lids, leaving the cloths, however, on. The Hadji had with him two of my servants, and he and they crushed in their hands all the grapes that they found in the risen cake that had escaped the feet of the treaders.
I had arranged that the wine when made was to be divided between us haphazard, and now the priest told me that I must make up my mind how I wished to have my wine—fruity, syrupy, dry, or very dry. For though as yet the jars had been treated exactly in the same way, now the treatment must differ for making the various different varieties.
He told me that for immediate drinking, i. e. after the next summer, a dry variety was best, but that for indefinite keeping the more fruity the wine the better.
