Weaker than I expected
Seemed strong until I used it in my home-made mint choc chip ice cream. Recipe called for quarter of a teaspoon of peppermint extract. I ended up using three whole teaspoons and the mint flavor is still overwhelmed by the chocolate chips. You can hardly taste it. That's 15ml versus the 1.5ml in the recipe. Ingredients are "rapeseed oil, peppermint extract". So, really I've bought oil flavoured with the extract, not the extract itself.
