Having seen the
@NorCal set up, and tasted the wine, I'd say you're being too hard on yourself. Because the wine is already excellent, and any of us would be proud with that result. And the fruit there is beautiful and well tended, and likely better than anything out of a Lodi commercial vineyard. I have not tasted enough Cabernet Franc to know exactly what to look for, but are you comparing apples to apples or Gala to Granny Smith?
I had another thought too.
@NorCal, you mentioned that you minimize fermentation additives like Opti-Red or tannin. For sure, the commercial guys do not, and they have access to all the specialized toys.
Agree with this:
And that's not to mention how commercial process on a large scale is just better than what can be done in the garage. For instance, I was at a winery 3 days ago picking up grapes. They were loading the crusher and immediately steam cleaning the bins. Then the bins were filled with must and ready for fermentation. So in 30 seconds the 1000 pound bin was emptied, cleaned, sterilized and back in use with no wasted motion. I was thinking how smart and how quick that was with no cleaner needed. The owner let me use the steam wand to clean out my Brute fermentors and I was immediately impressed. It was a combination steam cleaner and pressure washer. Perfect. And likely every stage of the commercial process is like that.
