FWIW, my experience has been pretty much the opposite. The Chileans I did a couple years ago are decent, especially when considering that MLF didn't complete, low BRIX, high acid, slightly vegetal, required some front end work, I enjoy them nonetheless.
The Cali's that I've done have been better, Lanza fruit, Brehm fruit, and last two years the Colavita's fruit from Lodi. A pretty penny has been paid for both the Lanza and Brehm fruit, mostly because the grapes were crushed, destemmed, frozen in pails and shipped to me, a much more costly option but the best I could muster at the time.
Also did some frozen must from Spain through Grapemasters, not as costly as the first two, not as inexpensive as the Lodi fruit, this stuff is turning out great, the tempranillo is two years old now and came out of the barrel yesterday and is really good.
The Colavita / Lodi fruit has been a blessing, fresh Cab grapes this year for $29 / lug (closer to $39 / lug with shipping), costing under $3 per bottle for the fruit. Jury's still out on the finished product from 2018, and will be for some time. 2017 wine is still in the 30 gallon barrel, progressing very nicely, and will turn out to be really good, but I do believe that the 2018 vintage may be one of my best in the end.
Just a little different view from my perspective........YMMV
