80g for how much H2O, and how many glasses do you get out of that? We built a japanese drip using a cone-shaped separatory funnel (it arrived at the lab with a tiny notch in the glass/glass wedge and I opted to "upcycle" it) and a chemex, but it only holds about 500ml. The coffee is fantastic, but 500ml even highly concentrated doesn't last too long around our house..
