Good Gracious! The rain!

It is rare indeed to see rains this heavy come so early in the Fall. We've had a LOT of rain over several precipitative spells this month, whereas usually September is fully dry for at least the first 2-3 weeks. And the first rains are usually little affairs, whereas today we're facing two or three waves of a dying typhoon.

I think that most of the Pinot Noir is still hanging in the vineyards. It should stop raining by next Thursday or so, and a few days of sun will help, but this is simply too much rain.

Modern varieties, however, ripen earlier and all mine are picked (Cayuga was the last; it came in yesterday, whereas Leon Millot was picked two weeks ago and is already finished not only with primary fermentation but also with MLF!).

Every year is different. Just look at our current radar image:

 

An interesting article about modern varieties of grapes/wines in Vermont, and how successful they are becoming:

Read about it here.

We are seeing a wave of modern winegrapes moving over the country. They are much Greener than the classical vinifera wines whose genes they carry (along with the genes of hardy American grapes): less spraying, less tractor fuel, more cold hardiness, earlier ripening. The wines are the true test, though, and the wines can be really excellent.

Yet another reason why modern varieties of grapes are better than the old vinifera varieties

Napa is going to replant about 15% of the whole valley, due to the surprise inability of a rootstock (promoted 20 yrs ago by UC Davis) to withstand Red Blotch Disease.

Read about it here.

This is yet another reason why modern varieties (sometimes called "hybrids", with American grapes in their parentage) are better than vinifera. American grapes have evolved to keep up with the attacks by fungi and viruses, whereas for 2000+ years we have prevented vinifera grapes from evolving (by cutting and rooting them, instead of allowing them to make seeds, and then growing the seeds), so vinifera grapes have not been allowed to develop defenses against new microbe attackers.

Pretty Darn Good Harvest Weather

I have a few "modern varieties" of grapes still hanging, but have harvested seven varieties already (they ripen earlier than vinifera do, as a general rule). But I think most vinifera grapes are still out there on the vines. Their growers are glad to see a later-than-average start to our famous Fall rains.

The 15-day forecast shows 100% chance of of our first heavy rain on Oct 15, so that is a target date for some growers who will want to pick before it hits. But other growers who need a touch more ripening may wait through that cycle (they'll rightly say that their grapes needed a quick freshening from some rain; they may even rightly say that a bit of rain can push more carbohydrates (sugars) into the fruit, which at first seems counterintuitive). Too early to tell, yet, when the next rain will come, after the first wave hits. There is typically a following period of regained nice weather, after the first rain.

But usually the first Fall rains come in late Sept or early Oct.

We've had a very unusual drought this year--only 0.25" of rain in the July 1-Sep 30 quarter! That's the least in EIGHTY YEARS! And we always get rain until July 4-5 or so, so this is quite unusual.
