Veraison is complete. Proof of work.

The only task I truly dislike in the vineyard? Bird netting. Not because of birds—but because of the neighborhood squirrels. Frustrating, tedious, and absolutely necessary. They’re relentless. Hopefully they don’t find any kinks in the armor.

Today was a long one.

Topping, lateral thinning, and suckering are done. Cabernet Sauvignon is a beast—vigorous and unruly, especially with my tight vine spacing. Most vineyards space vines 6–8 feet apart. Mine? Just 2 feet. Precision is non-negotiable.

Brix levels are sitting at 17–18, tracking toward a late October harvest. Everything’s on schedule.

Veraison marks the turning point: the onset of ripening.

Chlorophyll fades, anthocyanins rise—bringing color and sun protection. Sugars accumulate, glucose and fructose climb. I’m aiming for 24–25 Brix, roughly 1 Brix per week (give or take).

Acidity shifts. Malic acid drops, tartaric acid takes the lead. Aromatics begin to bloom—fruity, floral, and varietal notes emerging with each passing day.

Now begins the ripening phase.

Protect your grapes. Protect your time.

Nature prints squirrels out of thin air.

Not your grapes, not your wine.

In Japan I see grapes wrapped in white paper. I assumed this was so birds don’t eat them.

Looks amazing! 😉

You literally ought to be asking yourself all the time what is the most important thing in the world I could be working on right now, and if you are not working on that why aren’t you?

Cab only? Whereabouts?

My vineyard is in someone’s backyard up in Browns Valley, Napa CA.

I mainly do Cab because it’s what I grow. I have done Pinot in 2019 & 2020 but the vineyard I bought grapes from sold. I made a small amount Petit Verdot last year to blend with. I also buy Cab from a vineyard in Howell Mountain and might be getting other Bordeaux verities from there too but we will see.

Any Franc?

No Cab Franc maybe next year

Curious. I'm yet to taste anything from Napa that doesn't seem like it could have been grown in the Barossa. I've had some surprisingly delicious wines from the Finger Lakes (including a Franc) and Arizona (Caduceus), and further north, Oregon too. But, generally, have found that whatever the US can do, in terms of wine, I can find an equivalent or better in Aus/NZ. Must try more. 🍇🍷🫡

I love all those regions! Barossa produces beautiful wines; some stylistically reminiscent of Napa, but still quite distinct. Napa Cabernet Sauvignon tends to show higher acidity and firmer tannins, while Barossa often leans toward riper fruit expression and softer structure. That said, you can absolutely find compelling equivalents in Australia (especially Margaret River) and New Zealand (particularly Central Otago, though it’s more known for Pinot Noir than Cab).

In Napa, I see three broad terroir categories: valley floor, hillside slopes, and mountain sites. Each yields markedly different styles in terms of aromatics, tannin structure, acidity, and alcohol. Unfortunately, many wine drinkers outside the U.S. rarely encounter slope or mountain grown Napa fruit or even well crafted Napa Cab in general. The diversity within the region is often underappreciated.

Thanks for your note. I love chatting about wine with fellow enophiles!

Come on the pod. Let's annoy listeners with oenphile and gastro chats 😂🤤

Would love to!
