Some goji berry varieties are sweeter than others, but it really comes down to harvesting at the correct time. While goji berries turn red very quickly, they will continue to have a bitter taste until fully ripe. In general, goji berries should be left to ripen for several weeks before harvesting to attain that slightly sweeter flavor. Once they turn red, taste one every so often to see how the flavor is changing as they ripen on the plant.
