My experience is; After the normal Calvados and coffee, Calvados drinks, out comes a preserving jar with 2 large spheres inside. After much intrigue, the contents were described as Quarante Quartre (44 if i've spelt thin wrong), and the spheres were 2 oranges. From what we understand, the home made Calvados is further distilled to Eau de vie and that is the base liquid of the Quantro copy. We have tried the following recipie with both a supplied Eau de vie, and some of the fruit's de alcohol from the supermarkets, both with success; 1 large perserving Jar 2 large oranges, pricked with a knife 44 times and placed in the preserving jar (you could get awa with 1 orange) 44 sugar cubes disolved in enough eau de vie to fill the preserving jar (add more to taste during next couple of months) 44 coffee beans (to give colour) Leave for a couple of months, and voila, you have our your home made Quantro. Passed the recipie to friends who devourd a litre in 1 evening. Give it a try (no responsibility taken for any misshaps etc...) Anyone else got any recipies to share ????
