American Oak Chips are roasted between 350 - 375 °F to give them a medium toast. They will allow you to imitate storing your wine in an oak barrel without the expense, giving you notes of vanilla and caramel. American oak chips have more bite, or aggressive flavor, than French oak chips.
For white wine, 1 cup of chips is recommended. Try 2 cups for a red wine.
Simply boil in water for 10 minutes, then drain and place the chips in your plastic or glass fermenter before transferring.
