Each spring I’m asked how the vintage is going so far. This year the questions have come more frequently as we have experienced what seems an endless series of rainstorms. In a nod to working people not involved in agriculture, it feels like every week has included a couple of rainy days, but skies have cleared for the weekends. The past week was no exception. Rain poured down on Thursday, May 27th, but then the sun returned and shone throughout Memorial Day weekend. We expect more fair weather for the rest of the week, so perhaps we have turned the corner.

The recurrent rains remind us of the 1998 vintage when it also rained periodically until June. The impression is that we’ve had a really wet spring, but the fact is that the year is pretty normal to date. While it has rained regularly, it hasn’t always rained very much. What … More…

In my last post, I wrote that working with the terroir of a vineyard site is like being handed the keys to a new BMW. How do you drive it?  A writer friend of mine reminded me that I hadn’t answered that question yet, so we sat down for a little question and answer session, which follows:

What is your definition of terroir?

Simply put, it’s all of the physical characteristics of a site. That includes soil, climate (including rainfall, wind and fog) and elements of topography like elevation, slope and exposure. Beyond those physical features, of course, your farming philosophy will also come into play.

What makes a potential vineyard site look promising?

Let’s assume you are in a cool climate region like Carneros appropriate for growing Pinot Noir.  When considering bare ground for a vineyard, you need a clear picture in mind of what constitutes a good vineyard, which, of course, … More…

Over the weekend of May 16-17 this year, we experienced a brief but significant heat spike. Our vines had begun flowering the previous week (less than five percent), and temperatures had ranged from the 70s to the low 80s throughout the week.

As the mercury approached high 90s F., the vines had moved into full bloom. Grapevines are rather vulnerable during this period and require moderate conditions for complete pollination. Extremes of cool, hot, dry or wet weather can interrupt the process.

A good synonym for a vintage is “weather pattern.” Each growing season is a collection of fog and heat and wind and rain events. As wine grape growers, we can’t control the weather, but we do try to react to it in an appropriate manner to obtain the end product we want.

This year, as in 2007, the heat and subsequent rapid and incomplete flowering gave us little shot berries and … More…

It’s been raining off and on this week. We only have a day or two of pruning left, but we’re not working. The cover crops are so high and wet in the rows that we quickly get soaked to the waist, and that’s miserable.The rainfall has been pretty evenly distributed this winter. Although the soil is pretty saturated, the cover crops have done a good job absorbing excess moisture. We haven’t seen a cover crop of this size in years. The vigorous growth is welcome, because the roots penetrate the soil. When the roots die back, they leave room for oxygen and water to move down deep, and the plants also break down into fertilizer and organic matter in the soil.

The vines look relaxed, in great shape … More…

It’s Valentine’s Day, and we’ve received a wonderful valentine – over a week of beautiful weather, with highs reaching 70 and lows in the 30s.

Heavy rains have brought us close to 20 inches for the season, very near normal, which is slightly less than 22 through this month. By comparison, last year we had just over 11 inches to date.

I have been sidelined with the flu, which has seemed ironic during this past week of warm, sunny days. Nabor has been busy in the vineyard, and with dry weather forecast, he should finish pruning our home ranch, The Donum Estate, and nearby Ferguson Block by early next week. Then we start tying.

I’m on the mend, so we’ll head up to Nugent Vineyards next Saturday and start there. … More…
