Sweet??? ewwww It was too over-the-top for me, yin!! (I tried, but I couldn't learn to even pretend to like it.)Wheat grass is VERY easy to sprout. You might like nibbling or munching on it raw...
There is a "green-color" vegetable-fruit(?) beverage you can buy at local grocery stores. It would be in the refrigerator section (next to carrot juice, strawberry-banana, etc.). Sorry I can't remember the brand....
When I took my first sip of this thick "green" beverage, I noticed a distinct 'wheat grass' sweetness....
Maybe that drink is on your grocer's self? Can try out the flavor...
