atleast in some of the pics the trees show a lot of bourbon characteristics rounded rippled leaves, slighty acute angle to the brances. long droopy branches with wide internode spacing and ball-like fruit clustering. although in some other pics the plants look more typica like. thought i saw some copper tipped leaves, could've been the lighting though and more flat narrow leaves. but certainly very plausible that it is bourbon. the french did plant plenty of bourbon in french indochine a century or so ago. i beleive Ukers mentions Vietnam 'Grand Bourbon' . do you know any more specifics about this area where these farms are? altitude. rainfall. how much land planted with bourbon? i've felt for years south-east asia was the final frontier for specialty coffee. i see no reason why the highlands of thailand, laos, vietnam, yunnan and the northern phillipines couldn't produce great coffee. they all used to be arabica producing regions before rust wiped most of their production out long ago.
