Greg:
Unfortunately, it's impossible to tell what the alcohol content of these are from the descriptions on the Chef Rubber site. You'll either need to go to the manufacturer's site or call Chef Rubber customer support. I had a tough sourcing problem that they were able to help me with.
Gold standard for flavors, though, is Amoretti . They are expensive but everyone I know says they are worth the difference when flavor is important. If you look at the details tab for their products it will let you know if there is alcohol.
They have generic extracts (e.g., rum) and often taste-alikes for premium brands (e.g., Amaretto, Kahlua) and often have both water and oil soluble versions of the same flavor.
Amoretti also makes edible perfume sprays - you can add aromas to the outside of pieces just before serving them. It sounds weird but it's way cool.
