Lodi 101 (for true-blue Lodi wine lovers)

Lodi wine lovers at 2019 Lodi ZinFest

Have you found yourself becoming a true-blue Lodi wine lover, almost to the point of some kind of geekiness?

Scary thought? Well, if you’ve come to love the gentle yet refreshingly pure and fruit-forward styles of Lodi grown wines... not just the sumptuous yet feminine Zinfandels, but also the pungently spiced Grenaches and earthy Tempranillos, the crisp and precise Albariños and Vermentinos, plus the sheer variety (everything from Aglianico to Barbera, Kerner to Piquepoul, Touriga to Zweigelt) being grown here...

If you’ve also become intrigued by the history of Lodi’s winegrowing industry – how most of it, for instance, is dominated by families who have been farming in the region as far back as the 1860s (the opposite of the “new money” feel of what passes for “wine country” these days) – not to mention the region’s “small town” charm and earnest hospitality...

Then maybe you have become something of a Lodi wine geek!

If you need to face facts, there are some basic things that every Lodi wine lover should know. Not to “show off” your wine knowledge – Lodi wine lovers don’t tend to be pretentious or pontificating like that – but rather, to better understand exactly why you feel the way you do.  But it’s human nature to become a student of things we love most.

Therefore some the following questions-and-answers, we admit, are a little geeky. No shame in that. If to-know-him-is-to-love-him, then to know Lodi wine better only makes you love it more!

Hence, our “Lodi 101”:

To increase the profitability of wine grape production through well organized promotions and communication, and through viticultural research and education – including California’s original third party certified sustainable program called LODI RULES for Sustainable Winegrowing (now also visible on wine bottles with Certified Green seals, and available to growers outside the Lodi region with the optional usage of the term CALIFORNIA RULES).
