I like to make a concentrated form so I can just heat it if I want hot or put it right into a big ol cup and drink it as cold brew. So I store it in the fridge for several days in a glass jar and it comes out great. I can only do decaf, so I use organic espresso beans that are swiss water processed. Wonderful to have a quick way to make it into cold brew. I also used for tea Concentrate but took a lot of loose tea to make it strong enough. So will probably stick with hot steeping method there.
