My understanding of bor/gor varieties:
There are 3 varieties:
1) Boro( n)goru (heavy):
Hemotype 24
2) Borogu (balanced):
Very characteristic taste - very pepper, difficult for many people
3) Gorgor (heady):
(Personally, I haven't tried it yet) Description from ArtOfKava - "The taste is smooth and easy drinking.", "It's a bit heavier than our kelai but has similar euphoric effect and nice body relaxation."
We can find many more variants of these names. This is due to the fact that on Vanuatu itself they can appear in various variants and the fact that these names are not easy to remember by people outside of Vanuatu and thus distorted.
They probably all look the same and are therefore considered to be one. In this atlas (
link) they appear on one page with common photos. Probably the terms bor/gor have meaning related to appearance features. Any of you know what they mean?
In this Vanutu kava list
(link) there are 3: Borogoru, Borogu, Gorgor. Which seems to confirm my opinion.
