Lean vs Big

[megawill]

Okay so this comparison (Lean versus Big/Overblown) showed up in another post and I'm trying to distinguish in my novice wine knowledge exactly what is meant by each.

Can someone define a lean wine as well as Big Wine (and give some example of bottlings under say $20.00)?

Lately, I've been drinking a lot of Aussie Shiraz (Yangarra Park, Jacobs Creek, Alice White) and California Zin (Seghisio, Buena Vista, Rancho Zabaca)as well as some Italian Primitivo and Blends (A-Mano, Falesco Vitiano, De Majo Norante Sangiovesse)...so if anybody has some examples in these varietals it might help my untrained palate understand a bit...

thanks in advance....
