Chianti Classico vs Brunello Day Tour Logistics — Too Ambitious from Florence?

[Rede2mption]

Planning a 3-day stay in Florence this October and trying to optimize one dedicated wine day without turning it into a rushed Instagram checklist.

Current debate:

• Focus purely on Chianti Classico (Greve + Panzano + Castellina area) with smaller producers and maybe compare galestro-heavy soils vs alberese influence
  or
• Go south and do Montalcino for Brunello, even if it means longer transfers and fewer wineries.

I’m mainly interested in production differences, aging philosophy, clone discussions, oak approach (large Slavonian botti vs smaller French barrique), and vineyard exposure — not luxury tasting rooms.

Has anyone done both as day trips from Florence and felt one was significantly more rewarding for actual wine geeks? Also curious whether harvest season traffic in October makes Montalcino unrealistic for a proper deep-dive day.
