I have been doing cold brew for about 2 years. At home I use one of those huge massive pickle jars, it makes enough for a few days. I use the ratio of coffee to water you would for a hot pot. I have made it with all types of beans, light to dark. Light I have noticed I need to let brew longer. Normal is 12 hours but if it sits longer it's just fine. With the light, it's 18-24 hours. My house is cool enough that I just leave the jar on the counter. To strain it I take paper towels usually one large or two smaller and light my colander set over a bowl (my Kitchen Aid Mixer bowl) slowly pour some in and let gravity work. Then I transfer it to a mixing bowl that has a pour lip (I don't use it first because it's too shallow) so I can put it in used fruit juice jars. Usually fills up 2 jars and maybe a tall glass which I immediately have. the jars have a sealing action, and you will get that pop when you open them, keeps the coffee fresher. In the refrigerator, they go.
