I've been doing my own cold brew for a couple of years. I was using Starbucks french roast, but switched over to Don Pablo several months ago. About a month ago I was suffering through a cup of Don Pablo cold brew and I realized, this tastes like fucking rotting garbage. Why am I doing this? So I went back tot he Starbucks but have been experimenting. I was thinking of trying the Starbucks DIY cold brew kit at home, when I get the cold brew from the store it really does the trick, the homemade stuff just isn't the same, so I considered that. The stuff in the store hits me like amphetamines. Right now I'm doing the Chameleon premade cold brew, especially the vanilla. Good stuff, not the same but it doesn't taste like artisanal midwestern ass crack and it seems to work ok.
