What's a good alternative to mouthwashes that contain alcohol?

A good alternative is natural mouthwashes, which are typically alcohol-and-sugar-free. Many of the natural ones use baking soda as a natural abrasive to remove stains, plus pure mint oils or other essential oils, or even ginger for flavoring. Look for alcohol-free mouthwashes. Look for alcohol-free mouthwashes, such as Tom’s of Maine, and soon to be released alcohol-free products from Scope and Crest.

A great alternative to mouth wash would be to use a device called the Water Flosser. It is has been shown to be effective with plain tap water. Three studies have compared the Water Flosser to traditional string floss and in each case, the Water Flosser was superior to floss in improving gum health; specifically it was much better at reducing bleeding and as effective at reducing plaque. All the studies were done with plain water. Simple, easy, and cost effective.
