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 i’s 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 earth over millennia.
