The chemical composition of a peat bog depends on its geographical location. It’s all location, location, location!
Peat from different bogs can be distinguished by its chemical fingerprint ~ and the chemical fingerprint of a bog is still distinguishable in the final spirit.
Peat is created from the flora and fauna of an area. If you had a wooded area, the peat will be different from an area where the peat was mostly formed from heather – as in along the “Low road” in Islay. Here, it is also very salty due to the prevailing winds coming off the Atlantic Ocean carrying salt, also the salt-laden rain falling on the West coast of earth over millennia.
