This week, the San Luis Obispo Tribune posted a nice article pointing out the terrific representation of San Luis Obispo County in the two most influential year-end "Top 100" lists published by the Wine Spectator and by the Wine Enthusiast. The Wine Spectator included seven local wines in their Top 100, while the Wine Enthusiast added three more in their Top 100. Let's stop and think about this for a moment. That's 10 of the 200 wines represented in the two lists from our little county, or 5%. And even better that most of the wines listed were toward the tops of the lists. Already pretty satisfying, right? It's actually even better than that.
How much wine does San Luis Obispo County make, compared to the rest of the state, country, and world? In 2016, San Luis Obispo County ranked seventh in the state of California by bearing acreage according to the USDA:
- San Joaquin: 68,210
- Sonoma: 58,007
- Monterey: 44,095
- Napa: 43,589
- Fresno: 37,831
- Madera: 32,763
- San Luis Obispo: 31,480
Overall, our county represents 6.8% of the 459,629 bearing acres in the state of California. So, 5% doesn't seem like that great a representation.1 But of course, not all the wines in the two "Top 100" lists are from California. In fact, just 39 of the 200 wines in the two lists (17 in Wine Enthusiast and 22 in Wine Spectator) are from California. So, that's 25.6% of the state's "Top 100" representatives that come from SLO County. Not bad.
Perhaps you'd prefer to look at what percentage of American wine our little county represents? Opening up the list to wines from Washington, Oregon, and New York adds an additional 22 wines. That reduces SLO County's percentage from 25.6% to 16.4%, still well above the 3.45% of the country's total production that San Luis Obispo County represents.2
Or perhaps you're prefer to look internationally. In 2015, the United States produced 10.48% of the world's wine. So, San Luis Obispo County produced 0.36% of the world's wine: just one out of every 277 bottles made. That means that in the two "Top 100" lists, the 5% that SLO County represents is overperforming by something like 14 times, measured as our percentage of world production.
However you choose to measure it, we punched way above our weight class in 2017.
You go, San Luis Obispo County.
1. It's actually a little better than it sounds, since although SLO County represents 6.8% of California's acres, it represents something less than that of its production. That's because coastal regions like ours generally produce many fewer tons per acre than counties in the Central Valley. Figuring out by how much is a little tricky, since production isn't tracked by county, only by Grape District. In the California Grape Crush Report for 2016, District 8, which includes San Luis Obispo, Santa Barbara, and Ventura Counties, produced 224,584 tons. If SLO County represents the same 67% of tonnage that it represents of the district's bearing acreage, which seems reasonable, it would produce 150,471 tons, or about 3.7% of the state's 4,031,000 total tons produced.
2. This calculation required a bit of cross-referencing, since grape acreage statistics in states outside California, Washington, Oregon, and Texas are hard to come by. I used instead the tons estimate I calculated in the above footnote, and calculated the percentage of total national production based on the Wine Institute's data that California represents roughly 85% of the United States' total national production.
