One can lab grow flawless emeralds, rubies and diamonds. So with enough lab work, lab made wine I would not find unexpected.
Which makes it all rather ironic. Such innovating technologies are simply duplicating an already massed produced wine, and thus further reducing total market wine diversity (i.e. yearly varietals, varieties, and all those little idiosyncrasies that make each bottle of wine so unique and wonderful), and ergo reducing wine making innovation. Again -- always ironic when tech, which always talks about the "innovations" in their methods, really ends up doing the opposite elsewhere in the industry and to the product.
But, there are enough niches in the wine consumer pool to satisfy both only those that want consistency and don't care if the wine was made in vat, and those that want something of a more traditional source. To each their own.
