Great for cold brew. The glass is strong, but glass. Doesn't feel as strong as a 1 gallon pickle jar but strong enough. My wife doesn't grind coarsely so I have some grist at the bottom of the glass but it really isn't that bad and I'm fine with that. Rough sanding will likely solve this problem. I have personally found that 3 cups of ground coffee gives me the flavor and strength that I love in coffee. Your mileage may vary, but this should give you a good starting point.
