Grading My 2014 Napa County Cabernet Sauvignon Acreage Forecast
In 2015, I presented at the Vineyard Economics Seminar. At that point, we only had acreage data through 2014. The presentation was made publicly available. At that time, I predicted that, for the next several years, Napa County Cabernet Sauvignon acreage would increase by 1.25% annualized (per USDA-NASS Crush Report numbers). I decided to check in on that prediction this year. In 2014, acreage was 19,665. A 1.25% compounded annual growth rate would mean 20,667 acres in 2
Quick Take on the Latest Acreage Numbers
The recently-released Acreage Report indicates a 20% increase in non-bearing acreage over last year. That is possibly an enormous jump in supply. But it isn't unexpected. Assuming that acreage is reported in its second leaf, it was planted in 2017. Anyone planting in 2017 had seen prices rise an average of over 3.5% since the start of the Great Recession in 2007. That's a significant outpacing of inflation. For coastal regions, the numbers were even more impressive. It'

Regional Shares of California's Wine Grape Market by Yields, Acreage and Grape Sales Revenue
My last blog post included a new tutorial video showing how to use the Grape Data Tool to create charts depicting the what share of the wine grape market different regions of California have, by yields, acreage and grape sales revenue. Here are the charts below, for anyone who wants it. Note that the region names also include a listing of what USDA-NASS grape pricing districts were included in each region. #winegrapes #wine #winebiz #vineyards #yields #acreage #grapedatatoo
Using the Grape Data Tool to Assess Market Share by Region
Now and again, it's useful to try to take big picture views of our industry. One thing I like to look at is the way market share shifts between regions. Using the Grape Data Tool, it's easy to pull up all the data at once and build out some charts and tables. Unfortunately, I've found that I have a great deal of trouble properly displaying charts on this blog. Not sure why. It used to be easy. Instead of just posting the charts, which I will try to do next week, I create

Half of all Napa vineyards may be Cabernet Sauvignon by 2025.
Since 1994, Cabernet Sauvignon's share of Napa vineyard land has increased by roughly 50%. Other red Bordelais varieties have, as a category, seen a very similar shift, as you can see in the chart below. I know it's hard to see - Wix's blog setup is sub-par - so you'll have to zoom in to read the chart or try right-clicking to download it. If you'd like the original, just let me know. Over the past five years or so, the increase in vine-share dedicated to red Bordelais var
First update of the Grape Data Tool
The nice folks at USDA-NASS took a bit longer than usual, but they finally got the Acreage Report up on Friday. For me, that heralds a busy season. I'm burning the candle at both ends to update grape price forecasts and the Grape Data Tool. So far, I've got the Grape Data Tool's non-macro capabilities updated. Hopefully, they're working well. You can download it here or from the permanent, Excel Tools page of this site. The tool's use is governed by the Free Software Fou


Two Graphic Summaries of the Wine Biz
I've been putting together some charts and graphs for some projects and I just wanted to share two of them with the rest of the industry. I figured some people would find them interesting and, if you want to use them in some sort of report, please go ahead, just leave the attribution in. This graph shows Table 6 average price per ton, bearing acreage, total yield, revenue, tons per bearing acre and revenue per bearing acre for all California wine vineyards, normalized to 199
A tool so you can easily and quickly look up acreage data by variety and geography
I made a tool on Excel that allows the user to rapidly retrieve acreage data by inputting the variety and region. As readers of this blog know, I advocate greater use of basic data in this industry and I hope this helps. I made this tool with three purposes in mind for users: First, to create a quicker way to look up acreage data than flipping through a book or scrolling through spreadsheets. Second, to make it possible to carry the whole acreage report on a tablet and easi
