Hi everyone! First post here so apologies if I'm doing anything wrong.

This morning I picked up a Coffeega Alley600 from gumtree, and I'm wondering if anyone has used one before and knows how to get the best out of it. I've got other cold brewers but this one is by far the nicest (and most expensive!)
The interesting thing about this device seems to be the 2 valves, which allow control of water flow into the coffee grounds, and then from the grounds into the carafe. I feel like this adds quite a bit of customisation, but I'm not sure how to take advantage of it.

looking forward to your thoughts,
