At first glance, it might seem trivial to talk about the length of the pods. However, at an equal level of quality, the longer the vanilla pod, the more it is worth as a 16 cm pod logically contains more vanilla than a 14 cm pod.
The interest for the consumer is to buy 16, 18, or 20 cm pods that can easily be cut in 2 or 3. Supermarkets generally do not sell vanilla pods over 16 cm and even 14 or 12 cm pods can be hard to find !
LENGTH IS FLAVOUR
