Basically the same as giraffe and c-rider, I cold brew based on the process outlined on an AHA Zymurgy article, https://www.homebrewersassociation.org/how-to-brew/cold-brew-coffee-adding-coffee-beer/
I like to use African coffee as they don't have the jalapeño character that's common in South American coffee.
Coffee Toddy
3 oz coarsely ground coffee
3 cups chilled RO water
Cold brew for 24 hours in the fridge with a French Press. Add at kegging/bottling
