Arak (Persian: Arāk – اراک, IPA: [æˈɾɒːk]), also known as Soltan Abad (سلطان آباد – Soltān Ābād), is the capital of Markazi Province, Iran. At the 2011 census, its population was 526,182, in 160,761 families.
It is a major industrial city in Iran, hosting many industrial factories inside and within few kilometers outside the city, such as the factory of Machin Sazi and the Aluminum Factory of Arak. These factories produce nearly half of the needs of the country in steel, petrochemical, and locomotive industries.
As an industrial city in a developing country, Arak is subject to the issue of air pollution
Distillation begins with the vineyards, and quality grapevines are the key to making good arak. The vines should be very mature and usually of a golden color. Instead of being irrigated, the vineyards are left to the care of the Mediterranean climate and make use of the natural rain and sun. The grapes, which are harvested in late September and October, are crushed and put in barrels together with the juice (in Arabic el romeli) and left to ferment for three weeks. Occasionally the whole mix is stirred to release the CO2.
Numerous stills exist including stainless steel or copper, pot and column stills that will affect the final taste and specificity of the arak. The authentic copper stills with a Moorish shape are the most sought after.
The finished product is made during the second distillation. The alcohol collected in the first distillation is distilled again but this time it is mixed with aniseed. The ratio of alcohol to aniseed may vary and it is one of the major factors in the quality of the final product. Another distillation takes place, usually on the lowest possible temperature.
For a quality arak, the finished spirit is aged in clay amphoras to allow the angel’s share to evaporate and thus the remaining liquid is the most suitable for consumption
