Hi coffee enthusiasts, I'm new to the cold drip world and have recently got my hands on a second hand hario cold brew device. I have follow 1:11 coffee to water ratio with 0.8 drip rate. The recipe said it would take 9 hours but mine went through in nearly 3 hours. The only information I can find on my device is that it should take around 3 hours to make cold brew as the filter has multiple holes making it faster. However it did not taste good, no floral light coffee like I expected. Also I wasn't sure if I had made a concentration of a ready to drink brew. The coffee beans however were on he darker side of a roast. Any help would be great as I hate wasting coffee as fun as it is to experiment. I'm also using distilled pure water.
