Good morning all

I feel this is a subject that a few here may be able to answer..

So after using a few differment methods of brewing it, I’ve finally taken delivery of my hario mizudashi cold brew coffee pot, so the question now is which beans/grind are people using?
I’m not at the home grinding*/roasting stage just yet, and I prefer a fuller nutty/chocolatey flavour to my coffee as opposed to the floral edge, so just thought id see what you guys are uing and where you are getting them from

Cheers in advance

(*also looking at best grinders so all recommendations greatly recieved)
