The Julep Strainer is a perforated metal strainer in the shape of a spoon which fits snug across the top of a boston cocktail shaker. The julep strainer is to small for the opening in the container. but however does fit gently within the mixing glass at an angle. It takes a little practice, but adds a really nice touch to the process. This Julep strainer is made of quality professional grade stainless steel.
