First of all terpenes have zero flavor, only aroma. Terp talk has done nothing but ruin weed and the timing isn't coincidental. Fake terps are now the legacy of American weed. Fake American , synonamous. Thats domestic weed now that big corporations who won't grow legit bud have seen tons of the shit sold for craft prices. Its too late now they've been selling fake weed in Arizona since 2012 (Az ops are pheno farms for big tobacco, and Az mmj is the infected pulled sprayed renamed culls from those ops (and the thousands of distillate pen flavors of course,which all taste like saran wrap anal rape))
I've concluded 99% of the population absolutely cannot perceive flavor. Especially on the west coast. Fukashima or something for them fucked up. Evolution has failed us. Stuff that's suppossed to make people puke, the masses now claim to be enjoy. Tide pod Americans... Plain vanilla SCENT is now a luxury weed FLAVOR... Thats todays reality: people smoking aromas and claiming to get flavor from it. People claiming lemon og gets its flavor from an easily switchable scent product: fruit peel limonene,when it's actually a complex blend of acids, none of which are on a terpene panel.
Any breeder who, in 2019, doesn't even own a vaporizer and/or do extracts, they are excluded from the flavor discussion, they do not understand it. Earthy? That's kinda wide catch all at this point. You gotta pry, does that mean sandalwood? Ancient buried banana crystals from alien stoners? Biological? Like dirt? Aint no weed on earth that tastes like dirt btw, just a bunch of dirt growers who don't know how to keep their bud from tasting like nutrients.
Tldr: Most people growing smoking and selling Cannabis are unqualified on multiple levels. Quality has been replaced with marketing tactics. Terpenes do not have taste. Citric acid is not a terpene but i taste it in lots of weed.
