I use imitation. I actually like it better. I don't know the alcohol content, because it's not listed on the bottle.
Does imitation vanilla extract have alcohol?
Most extracts, be them imitation or pure, contain some level of alcohol. The alcohol is used to help extract the vanilla flavoring from the beans. Pure vanilla extract must have at least 35% alcohol content by volume. Imitation vanilla often contains less, sometimes as little as 2% alcohol.
For a truly alcohol-free vanilla, look for extracts that say “alcohol free” on the bottle, or try vanilla flavoring instead, which may not contain any alcohol.
