I got a juicer a month or so ago... I can hardly wait to make some rhubarb juice. Going to have to wait 2-3 weeks as my rhubarb is just coming up. My wife thinks I'm insane, but I love sour stuff.
I've never heard of rhubarb juice.
I really like it for making desserts and unfortunately it is far too expensive overhere. Let us know the end results.
