preslove, there's this place by my work I can't remember what it's called, but I stopped in there to get a drink once and their cold brew was pretty fucking good. only time i've had cold brew, it is something I would like to try again.
I recommend the Toddy system. It's $32 on Amazon and they provide everything you need, sans coffee. I just go to starbucks (the only place in town that has full pound bags of beans that will grind them) and get a pound of beans and have them grind them course, then pour in water and coffee grounds in the provided tub according to their instructions. It creates this cool semi-firm blob that you let sit for 12 hours. After the 12 hours, you release the stopper and pour it into their carafe. This is a concentrate that you you mix with water/cream to your liking. The coffee is really smooth and doesn't have that acidic "bite" that most coffee has.
A real plus is that it takes a lot less time and no clean up during the morning. I just mix the concentrate with water and a little cream and sugar and go to work.
Also, Toddy's component prices are pretty reasonable. You can get replacement filters (they give you two, which are reusable) for 2/ $5.79 on Amazon. I forgot to bring the stopper for mine when I moved to Texas, so had to order another one from amazon. I got 6 for $5. It's a real plus that they don't rape you on replacement parts.
