Chianti Rufina makes good wines, the equal of Chianti Classico in quality but with a more rugged, savory character, the product of its cooler, mountainous terrain. But it's not in Chianti Classico, which makes nearly 12 times as many wines per year.
In October I visited the region for the first time to write about its new higher-end classification, TerraElectae. I was impressed by the wines. If you like cool-climate Sangiovese, you'll like these: more red fruit than black; savoriness more than fruitiness; good freshness and structure.
Here's the article I wrote for Wine-Searcher. Cheers.
