“New” to wine — what should my next step be based on recent experience?

(Apologies if this is not the right place for this post — I didn’t see a “newie questions weekly thread” )

We live in Arizona and it’s getting properly hot, so we’re trying to (re)enter the wide world of enjoying wine with cool, *dry* whites. I started by looking at a chart of the driest whites and found 3 French dry whites at our local Total Wines & More. (Aside: we think we favor French winemaking based on past experiences). We’ve opened two of those, so far, and the one below I want to use to further our hunt as we *really* enjoyed it. That wine was:

[Chateau Belingard Bergerac Blanc](https://www.totalwine.com/wine/white-wine/sauvignon-blanc/chateau-belingard-bergerac-blanc/p/94068750) ($15, 750ml) which I know is

* a French white
* a combination of grapes (sauvignon blanc 60%, muscadelle 20%, semillon 20%)
* from the region Bordeaux, appellation Bergerac
* ABV 12%

**My question is**: how do I find the next bottle based on liking this? Should I look into other whites from this region / appellation? Do I instead pursue the grape varieties and ABV? And, most importantly, what resources allow me to identify similar bottles *that I can actually find and buy in Arizona (or get inexpensively shipped by the bottle since we’re not ready to order cases)?* (Note: we’re two people and generally drink a glass each per night so I’m trying not to buy too much at a time.)

Scanning through resources here and elsewhere it’s clear there are a lot of resources to explore the wide world of wine but I really want to focus on what I can actually get my hands on without breaking the bank ($15 and under preferred).

Thanks in advance and, again, apologies if this is the wrong kind of post or in the wrong place.

\*I say “new” to wine in the subject line because I’ve drunk wine for decades and have, now and again, explored wine but always been overwhelmed. I’m trying to take a much more targeted approach to learning (and buying) wine at this point.
