Yes! Feel free to check on it every so often to see how it’s doing. To do this, just pour off a couple ounces for a taste test. Such a test might go like this:

• 4 to 6 Days—Too sweet; not all sugar converted.
• 7 to 9 Days—Tastes like sparkling apple cider.
• 10+ Days—Vinegar taste becomes prominent.

Remember to cover it back up after checking it!
