Im in Australia and buying all my honeys at a local farm from a 1,200+ hive primary producer. Non pastuerised and fresh from the harvest.
All the rules are out the window on dark and light honeys, Ive had darks with delicate flavor and lights with strong flavor.
My ironbark eucalypt variety is rather delicate and my stringybark eucalypt is rather strong. Im brewing 100% (no diluted mixtures) eucalypts in Mead and have not found any of the problems associated with them. One problem you could be facing is a blended pastuerised multi-varietal mixure being sold to you under the name eucalyptus honey. Without a proper varietal its going to be a bit of a crap shoot as to what to expect but the standard dilution ratios in water and a taste will give you an indicator of where its going to be headed.
There are over 500 species of Eucapytpus and many more hybrids so judge anything labelled Eucalyptus honey wih a wary eye unless it tells you the exact variety.
The most popular varieties of Eucalyptus honey locally are:
StringyBark
Ironbark
Yellow Box
Red River Gum
Salvation Jane
White Box
Spotted Gum
Mallee
Leatherwood
There is no scent of eucalyptus/flavour in the honey. You have adulterated honey if you do. And no, people don't slather it on their skin here so you have honey and eucapyptus oil mixture for cosmetic use it seems.
Cheers,
