Reply To: What is your favorite brand of instant coffee?

Regarding coffee on Shabbos- I have a friend that owns a coffee shop where they sell a concentrated cold brewed coffee (a process that takes at least 12 hours). In essence it is similar to tea sense, where you can just add it to hot water and you’re done. I’m not sure everyone would agree that it’s permissible to use on Shabbos as it is not “heat brewed” during the process.
