Input: Read this: After 1965, differences between the Hot 100 chart and the Easy Listening chart became more pronounced. Better reflecting what middle of the road stations were actually playing, the composition of the chart changed dramatically. As rock music continued to harden, there was much less crossover between the Hot 100 and Easy Listening chart than there had been in the early half of the 1960s. Roger Miller, Barbra Streisand and Bobby Vinton were among the chart's most popular performers.

Output: the Hot 100 chart

Input: Read this: Nearly all beer includes barley malt as the majority of the starch. This is because its fibrous hull remains attached to the grain during threshing. After malting, barley is milled, which finally removes the hull, breaking it into large pieces. These pieces remain with the grain during the mash, and act as a filter bed during lautering, when sweet wort is separated from insoluble grain material. Other malted and unmalted grains (including wheat, rice, oats, and rye, and less frequently, corn and sorghum) may be used. Some brewers have produced gluten-free beer, made with sorghum with no barley malt, for those who cannot consume gluten-containing grains like wheat, barley, and rye.
Question: When is sweet wort separated during the brewing process?

Output: during lautering
