Aitor over at Old School Bakehouse gave me some tips on how they prepare the cold brew. The ratio he uses is 50g per 1L of water, using the same nylon bag setup I use at home. Since he uses very high quality coffees, he recommended to always increase the time it brews and keep the ratio, so that more special coffees can indeed last for more brews. A good default is 16-20h depending on what you want from the cold brew, and longer than 24h shows diminishing returns.
