The first step, where the wort is prepared by mixing the starch source (normally malted barley) with hot water, is known as "mashing". Hot water (known as "liquor" in brewing terms) is mixed with crushed malt or malts (known as "grist") in a mash tun. The mashing process takes around 1 to 2 hours, during which the starches are converted to sugars, and then the sweet wort is drained off the grains. The grains are now washed in a process known as "sparging". This washing allows the brewer to gather as much of the fermentable liquid from the grains as possible. The process of filtering the spent grain from the wort and sparge water is called wort separation. The traditional process for wort separation is lautering, in which the grain bed itself serves as the filter medium. Some modern breweries prefer the use of filter frames which allow a more finely ground grist.

What is it called when used grain is separated in the brewing process?
Answer: wort separation

In the north Eristov pushed southwest, fought two battles, forced the Turks back to Batum, retired behind the Cholok River and suspended action for the rest of the year (June). In the far south Wrangel pushed west, fought a battle and occupied Bayazit. In the center the main forces stood at Kars and Gyumri. Both slowly approached along the Kars-Gyumri road and faced each other, neither side choosing to fight (JuneJuly). On 4 August Russian scouts saw a movement which they thought was the start of a withdrawal, the Russians advanced and the Turks attacked first. They were defeated, losing 8000 men to the Russian 3000. 10000 irregulars deserted to their villages. Both sides withdrew to their former positions.

The most significant event between the 7th and 11th century was the Tripartite struggle centered on Kannauj that lasted for more than two centuries between the Pala Empire, Rashtrakuta Empire, and Gurjara Pratihara Empire.

The seventh century also saw the advent of Islam as a political power, though as a fringe, in the western part of the subcontinent, in modern-day Pakistan. The Chola dynasty conquered southern India and successfully invaded parts of Southeast Asia, Sri Lanka, Maldives and Bengal in the 11th century. The early medieval period Indian mathematics influenced the development of mathematics and astronomy in the Arab world and the Hindu numerals were introduced.

When did Islam begin to become a political power in India?
Answer:
seventh century
