RJ Spagnols Cru Select series of premium quality wine recipe kits include 16 liters (4.28 gallons) of varietal grape juice and concentrate that makes 6 gallons of high-quality wine on completion. RJ Spagnols sources their grapes from all over the world including Europe, South America, California and Australia, and each kit includes the required wine yeast for the specific varietal of wine, stabilizers to prevent off flavors and browning, and clarifiers to stave off cloudy wine. Depending on the style, Cru Select kits also include grape skins for added tannin and mouthfeel, oak chips to simulate oak barrel fermentation, and other flavor packs if needed. Cru Select kits are intended to be bulk or bottle aged after fermentation for 4 months prior to enjoying. Cru Select wine making kits make a fantastic wine with great complexity and mouthfeel, and are among some of the most popular kits on Homebrew Supply.
