Color me confused: the top positive review says in one place that you typically use 1 oz of coffee per 1 oz of water. That means you get fewer than 13 cups of coffee from a 13 ounce can? I know about the grind. I’m using the can as an example for quantity purposes here. You can yield so much more by making drip pots and adding ice. Sounds like very little yield. Is it really worth it?
That reviewer goes on to say (and they are a huge cold brew person) that you can make a couple of weeks worth of cold brew in four hours. I guess this presumes that a person (that is a coffee drinker) drinks only one 8 ounce cup of coffee per day? I’ve never met such a person in my universe.
A questioner on the mothership said the directions say to use 2/3 of a cup and does that sound like a lot. It does to me! 6 ounces? Nearly half a can of coffee and 2 cups of water? Is that accurate?
This product interests me greatly but getting a handful of cups from a one pound bag sounds very off.
I only drink one cup (10 oz average, so I am 2 oz over) of coffee on most days. I don’t do well with a lot of caffeine. Not all coffee drinkers drink to excess.
What is excess to you is apparently basic sustainance to many. Two cups of five ounces each would not even get most coffee drinkers I know our the door in the morning. At any of the places I did my time paying income tax, my 2 large (14 oz ) mugs each morning were deemed minimal because I cut off the coffee at lunchtime. Seems the vast majority stuck to 8-10 oz mugs but drank their preferred brew all day long…
If you look at the side picture, the bottom of the carafe is black and (scale is difficult) 1-1.5 inches thick. There’s a blade of some sort concealed in the bottom section. It might be a magnetic stir bar as used with the stirrers people have posted about, but the top positive comment in the reviews says that it’s hard to clean. Something has to be moving the coffee, it’s not working by magnetohydrodynamics.
Cold brew is usually brewed as a concentrate, being many times stronger than drip coffee. Then it’s diluted with water, to taste. So one batch of cold brew could possibly last someone for a couple of weeks. But yeah, the yield all depends on the ratio of grounds to water.
I found the instructions for this thing. There’s apparently a special “stirring cup” you place at the bottom of the carafe, which looks like a metal cup inside a plastic cup in the other pictures I found. I would guess the inner metal cup is on a ball bearing, and this is basically a magnetic stirrer with an over-engineered replacement for the stirring rod.
