If I know I’m hosting a larger crowd than one or two friends, my go-to is a large batch of cold brew. This allows me to serve both hot and iced coffee depending on my guests’ preference. I aim for 100g of concentrate per guest and top it with 100g of hot water or a mix of ice and cold water.
Coffee in water! I use a French press and pour it through a V60 filter because I prefer a clean drinking experience. My most used recipe for cold brew is 500g water and 83g coffee (1:6 ratio) and leave it for 24-48 hours (depending on how much warning I have).
From north west Spain (pot cofee) just using a pot, is a method that allows you to make coffee for an unlimited amount of people depending on the size of the pot:
