I recently purchased a kit and the juice bag had sediment in it and did'nt quite smell right although the juice tasted fine. The juice was also a little brown. It smelled more like a raisins raither than a good fresh grape juice, but that may be normal since grapes come from raisins. This is my second time to do this same kit and I dont remember my first kit looking or smelling like this. The sticker on the box indicates that its not old. Just looking for other opinions. Should Riesling juice be brown?
