My local home brew store has a Grand Cru Petite Sirah wine kit that I am thinking about purchasing. I know that the 10 liter kits are considered lower quility because of the smaller amount of grape juice concentrate. Has anyone purchased a Grand Cru kit and only rehydrated it to 5 gallons as opposed to 6? In theory is seems this would make a higher quality wine with better body...but than again that is in THEORY! Has anyone purchased a 10 liter kit and only added water up to 5 gallons instead of 6? And if you did, how did it turn out as opposed to adding the full amont of water up to 6 ?
