Yep, I always wondered that as well. From what ive been told and researched, Chilean juice/grapes are more consistent from year to year because of the consistent climate. California juice can be a crap shoot due to drought, floods, cool, warm temps. I got started in this hobby doing Chilean juice and so far its been good. This will only be my 3rd year doing Chilean juice tho. I did do a California Merlot last year and did not like it!I'm curious as to how much grapes of the same variety differ from different vineyards/suppliers.
For instance, did Merlot grapes as a whole from 15' all take on similar qualities since they were all harvested in the same climate at the same time?
Or do the different techniques used at the vineyards (for better and worse) show in the grape's quality?
That is the most important point. It's offered, it's relatively cheap, and whether it makes a great wine or not you'll learn something about all juice winemaking. If I listened to a lot of people on this site I'd have never tried Chilean juice, especially for red wine. I'm glad I did. I think the suppliers vary depending on the source of their juice. I'm lucky to have Harford Vineyards nearby as the products they sell have been of very good quality, so far (for the Chilean and Cali products, never tried the Italian or South African juices). And I can get whole grapes in the Spring.Why? Because it's offered and also, why not?
