A cocktail strainer is a metal bar accessory used to remove ice from a mixed drink as it is poured into the serving glass.
A type of sieve, the strainer is placed over the mouth of the glass or shaker in which the beverage was prepared; small holes in the device allow only liquids to pass as the beverage is poured.
The Hawthorne strainer is a disc (called the "rim") with a handle and two or more stabilizing prongs.
A metal spring fixed around the edge of the rim rolls inward to fit inside the glass.
The Julep strainer is shaped like a bowl with a handle, and will fit tightly into a mixing glass or shaker when inserted at the proper angle.
