Making cold brew is just one bag of cold brew beans ground on the French press settings, grind it into the filter in the toddy, and then you put 7L of water inside the filter, tie it, 7L outside and let sit for 20 hours. As for when you transfer it, you pour it into the little cubes used for iced coffee up to where the handles are (at least at my store) and then after you pour that into the keg you put the same amount of water in the cube as you did cold brew, mix in 2L of ice and pour it into the keg. If you need any more help
Lmk! I’ve only been at Starbucks since early February so I’ll try my best to answer, I only have the cold brew process memorized bc I do it almost every morning LOL
