My Palate Press piece for this month (which I really wish was entitled something involving “water” to make the subject more clear) is a bit about Waiheke Island, just off the coast of Auckland, and a bit about water footprints in the wine industry. The relationship between the two is that Waiheke — shockingly, for a North American accustomed to consistent public amenities like central heating and easy wi-fi (both unlikely propositions in New Zealand) — has no public water supply. In good years, residents and businesses and wineries meet their individual needs either by collecting and filtering rainwater (most folk) or with a “water bore” into the under-island aquifer (large and/or resource-full folk). In bad years, all of the above buy water from private companies with private water bores, and do laundry less often.
Waiheke is a good reminder, though, that whether water comes out of a tap or off the cistern parked next to your car, it’s always coming from the same two places: the sky, or underground (which isn’t to say that the two aren’t connected, but only that it’s helpful to think of the two compartments). Tap water is a bit like packaged boneless skinless chicken breasts from the grocery store. Someone else has done all of the hard work for us. Both distance us from the hows and wheres of the stuff we use. Butchering chickens is a pain*. It makes endless sense to divide labor, specialize, and let someone else with better equipment and skills and economy of do it for you. And bake your bread, change your car’s oil, and collect and filter your water. Still, all of these things make it easier to abuse the system. We don’t pay as much attention to our dinner’s living conditions when it didn’t live with us before it appeared on the table, nor to how it died if we didn’t kill it. I’d never really thought about water that way before wandering around on Waiheke; I try to conserve it, but I don’t usually think so graphically about what my convenient kitchen faucet implies. I’d never wish drought on anyone (and California and its people have my sympathy). But maybe it’s no bad thing to look for a drinking fountain in a place with no public water and find none, and remember that I should be just as conscientious about my water as I am about my free-range, local, organic Sunday supper.
More about my Waiheke visit, and about water, is on Palate Press.
*As I know from recent experience. The Great Chicken Experiment is, regrettably, over. The first two hand-me-down hens lived happily with us until the neighbor’s rooster discovered them and decided that they were his, after which they lived happily with the neighbor until she decided she was done with poultry and she invited me to dispatch the lot of them (after which they lived in my freezer and my stockpot). Save the (charming, darling) several month-old chicks, who we adopted. Unfortunately, having been raised entirely outside in our mostly fenceless environs, they’d learned to be very freely free-range. A trip through someone’s spinach was more than anyone was willing to tolerate (save, maybe, the chickens) and we handed them on to someone else. We miss them, though my garden does not.
My piece for Palate Press this month asks what California (proto-Davis) wine researchers were doing in the era before mass spectrophotometers and DNA sequencers and even automated pH meters and all the other fancy stuff wine scientists consider essential today. The short story is that they were trying to figure out what grows best where, and how, which is fundamentally what we’re still trying to do. The long story is on Palate Press.
The long story didn’t have space for me to really geek out over the fun of reading old research articles. I think it’s fair to say that science writing — of the by scientists, for scientists variety — wasn’t as dry then as it is now, not just because antiquated language is quaint but because the distance between normal-talk and science-talk was shorter then than it is now. It’s pretty accessible and often entertaining. There’s the simple, voyeuristic pleasure of being astonished at just how backward they sometimes were, and sometimes at realizing that they weren’t as backward as we tend to assume. And then there’s the higher-order pleasure of making stories by connecting what they were doing to what we’re doing and finding new meaning in both the historical and the modern.
But reading about someone else geeking out over light archival wine reading isn’t near as fun as doing it yourself, and the archives of Hilgardia: a Journal of Agricultural Science from the University of California, including much about wine, are freely available via the University of California Agriculture and Natural Resources Respository. When so much is pay-walled and protected, free access to land grant university resources — not just for subscribers, not just for local winemakers, and not just for the taxpayers of California or even the United States — seems increasingly meaningful, and a good reminder of this massive, excellent, egalitarian knowledge-sharing project we practice through land-grant universities and agricultural extensions. I won’t ask you to excuse my unfashionable patriotism.
An enormous lot has been said about the relationship, or lack thereof, between grape yield and wine quality. So why is my October piece for Palate Press about whether higher yields mean lower quality?
1. My Palate Press colleague W. Blake Gray took an interesting economic tack on the problem a few months ago, reminding me that I wanted to revisit what we know via the scientific approach.
2. I’ve been more than a bit obsessed with the contacts (and conflicts, and congruencies) between anecdotal and scientific knowledge of late. The yield-quality problem is a fantastic case of the scientific evidence we have strongly suggesting one position (higher yields ≠ lower quality) while some peoples’ experience suggests that more may be going on than science has yet to document.
3. It’s a perennial question for a reason (or two): it’s interesting, and it’s important. And revisiting interesting and important things is worthwhile.
4. Richard Smart wrote an article for Wine Business Monthly back in 2004 proving, via contrary anecdotes, that higher yields don’t always mean lower quality, and that the principle isn’t true from a scientific perspective. He also implied that anyone who thought that myth had a place in winemaking was 1) a moron, and 2) unscientific, and that riled my epistemological feathers enough to want to write on the same topic from a different (better)* perspective. More on myths another day.
The short version: the oft-cited yield-quality relationship is more about correlation than causation particularly from the perspective of the scientific evidence, but whenever we’re talking quality things get fuzzy (and social) and our perceptions about wine quality involve more than just measurable scientific variables.
The long version is here.
* Yes. I’ve just compared myself to a highly-accomplished viticultural scientist and found him wanting. Dr. Richard Smart is a marvelous scientist. He also, by this single account at least (I’ve not tracked down more examples), has ideas about which forms of knowledge-making are valid that I find deeply misguided.
