As for the OP, I drink wine but only red and only bitter flavour. I've had white wine and overall I've found it's sweeter than red, even if it is a bitter variety of it.
Depends on what you like. If you want something that tastes more like juice than wine, I'd suggest sangria or a chilled red wine like Lambrusco. Or you can go super cheap and get that Arbor Mist stuff. It's technically wine I guess.
