With the tease of Spring for a couple weeks in early February, it’s not difficult to think Winter is over and done.  But God has a way of letting us know he is still in charge.

April 1, 2010. Snow Cap on Mt. St. Helena.

Snow in San Francisco!! Perhaps on Friday or Saturday that could happen.  I am expecting to see snow ringing the Napa Valley by the weekend, but that is still only the end of February.  In 2010 we had a snow cap on Mt.  St. Helena on April 1st, and it wasn’t an April Fools joke.

The good news for now, is that the vines are still dormant, although it won’t take more than a couple of days at 75 degrees to see buds start to pop into this years new growth.

You may have seen a lot of  vines in the Valley this year with “long haircuts”.  Our Cabernet was “long” pruned a month ago, leaving canes 12 to 14 inches long.  Just as we see signs of bud swell this spring, we will go back into the vineyard and “finish” prune the vines, selecting the spurs to remain for this year’s crop.

Wicker Vineyards Cabernet Vines Waiting For Final Pruning Cuts

This buys us a couple of benefits.

First, it allows us to make the finish cuts just as the shoots start to grow.  Without all the long brush to pull from the canopy, there is no danger of breaking off the tender new buds.  This gains us as much as a week or ten days of frost protection by delaying the bud break.

Secondly, this practice helps us control Eutypa fungus infections.  The free fungus spores are released by rainfall, and infect the vine through the fresh pruning cuts.  When we make the final cuts, any early, wet season infection by Eutypa spores is trimmed off before it has a chance to work its way into the main structure of the vine.  This is a great example sustainable practice farming, preserving vine health without the use of chemicals.

Early April Snow Cap on Mt. St. Helena Was No April Fools Joke

2010:  A growing season to remember.

This was my 41st harvest in Napa Valley since making grape growing my career in 1970; and not one I will soon forget.  The unusually cool season tested the patience of grape growers, many of whom reacted by removing leaves and canopy in a misguided effort to “accelerate” the ripening process.  This season’s fruit had not been exposed to heat all season, and with the exposure created by removing leaves that provide natural shade, the fruit was subject to severe damage when the late season temperatures spiked to 110 degrees or more.

With experience telling us we would see hot weather before the season was over, we were very careful to leave leaf cover to provide protection to the “unseasoned” fruit, particularly on the afternoon side of the vines.  Not only are these leaves nature’s shade cover, but each leaf is also the plant’s tiny photosynthetic “factory”, providing carbohydrates and nutrient utilization.

We were also careful to anticipate the hot weather, making sure the vines were properly hydrated and nourished, much as we humans need plenty of water when it gets hot.  The plant reacts to the sudden heat much like we do, feeling the effects of sudden temperature changes.  When we go from 75 degree weather to sudden 100 degree spells, we find ourselves seeking shade, water and someway to cool off.

Our Howell Mt. fruit made it to harvest in prime condition.  The 2010 Wicker Vineyards Cabernet is in barrels and tasting lush and rich already.  I believe this is one of those years that will lend itself perfectly to our complex, elegant style.  Another Wicker vintage to anticipate.
