Extract vs. Oil vs. Flavor
What are the differences? Are there specific uses for each? For my first batch of peppermint bark, I used an old bottle of McCormick peppermint extract. It turned out quite well, but I thought the peppermint flavor could have been better. I visited Penzey's and unfortunately, they don't have any peppermint extract. So I bought organic peppermint flavor from Whole Foods. It has a more viscous consistency than extract, but I think I actually preferred the flavor from the extract (or perhaps I needed to use more of the peppermint flavor). I also have some peppermint oil and am wondering how that would work in the bark.
This is a great online supplier of flavoring extracts, oils and concentrates. Their website is also very informative on what the most appropriate uses are for extracts, oils and flavor concentrates.

i believe the differences of alcohol and oil-based products make one more ideal for flavoring beverages and the other for baking/cooking due to heat stability.
