Cool climate and clay soil = Chablis?



The truth, I have learned, is that cool/cold areas are best suited for white wine production for a variety of reasons. Whites generally ripen earlier, and they are more forgiving, flexible and adaptable. It is easier to make a good wine from a wider range of maturity than reds. So cool regions that have shorter seasons may still produce acceptable and even excellent white wines. That is not so true of red wines.  Red grapes need a long season of hot weather to mature to just the right sweetness.

Leaves unfurled

Now we know. Our new grape vines survived the winter.

We've had the most unusual weather. More than a week of warm sunshine and absolutely no rain. We have not watered in the vineyard or orchard, only the vegetables, flower garden, and greenhouse.

We launched our boat on the high spring tide in Killybegs on Saturday the 7th of May and delivered her from Donegal to Mayo arriving home Tuesday the 10th. We had no rain and little wind en route and it has not rained since. That's a long time without rain and wind in Ireland. How will the vines react to dry stress?  How will they react to a mild winter and frost only for a few weeks in April. Whatever wind we've had has been easterly and northerly again this whole week.

Where have the bees gone?

It appears that our bees have died. There is collapse of hives being reported all over Ireland this winter. The beekeepers remove the box and find dead bees clustered and the honey untouched. They are thinking that it was the wet summer and cool wet winter that caused disease to kill them off. Up to 50% loss and more being reported. Tragic!

But that spells disaster for our orchard and vineyard.  There are plenty of bumblebees. I saw one wasp and quite a few flies, but the fruit trees are laden with flowers that, for the first time since planting, have not been blown off by hurricane force winds. So I went out with an artist's brush this afternoon and pretended to be a bee.

I had seen an article about the Chinese pollinating their crops by hand because of the collapse of their bees and other insects. So I decided to try the same. I don't know if what I am doing will have any effect but I have to try.

 Meanwhile the grapes have not yet unfurled their leaves as it has been cold. But signs of life continue and hope remains eternal. We'll see what this foray into food production will yield this year.

We had one good year with a bumper crop of apples (2014). One bad year with nothing of note, no apples, one mini-pear, and a few cherries eaten by the birds just as they ripened. Growing food is not easy. I wouldn't want to have to depend on it.

Signs of life

In my last post, I said winter was over. But it had only just begun. Now in April, we've had brilliant sunshine but frost almost daily. 



Our experimental grape vines seem to have survived the winter.  They have not leafed but are budding strongly.  Hope!

The weather has been very strange. The winter was mild but very wet and stormy. Then the cold snap came just before most things started budding.  A few garden plants didn't survive but I am hopeful that the cold was enough to harden the grape vines. They need a bit of cold weather to shock them into action.The last week has been blissfully sunny with no rain at all. How very strange. We went from 3 degrees C to 18.5 degrees centigrade overnight. Now it's back down to 3 degrees again as we cycle within a huge anticyclone and the winds clock between northerly and southerly.

The fruit trees are laden with flower buds ready to burst open, but there is no sign of the honey bees. The hive appears to be dead. How sad, how very very sad. Especially after reading the astonishing novel called The Bees. I couldn't wait to watch them this year having studied their behaviour and read this profoundly influential story. But only bumble bees have appeared in our garden. What will we do?  There is word of hives having collapsed all over the country, thought to be the aftermath of an extraordinarily wet and cool summer that never came last year.

Meanwhile the climate change reports indicate that globally March was once again the hottest month on record (not here!) and the 11th consecutive month of increasing temperatures. According to data from the Japan Meteorological Agency (JMA), the average global temperatures were 1.07 °C (1.9°F) above the average in March since records began in 1891. Data released by NASA shows that March was 1.65°C (3.0°F) warmer than the averages between 1951 and 1980.

The National Oceanic and Atmospheric Administration (NOAA), the primary keeper of such data in the U.S., reported even more dire news. "The average global temperature across land surfaces was 2.33°C (4.19°F) above the 20th century average of 3.2°C (37.8°F), the highest March temperature on record, surpassing the previous March record set in 2008 by 0.43°C (0.77°F) and surpassing the all-time single-month record set last month by 0.02°C (0.04°F). The combined average temperature over global land and ocean surfaces for March 2016 was the highest for this month in the 1880–2016 record, at 1.22°C (2.20°F) above the 20th century average of 12.7°C (54.9°F)."


So according to NOAA's figures, we've already surpassed the 2 degree mark. Anomalies are occurring all over the world.

Meanwhile, last month we visited the Chiltern Valley Winery & Brewery near Henley in England and learned all about small winery viticulture in the UK. They had just pulled up all their grapes and replanted with new varieties. Their wines are quite interesting but they produce mainly with other growers' fruit. We learned principally that it takes a fair bit of investment to get a little operation going and so it's best to produce small quantities of liqueurs. We also learned that we planted the vines in the wrong orientation (up and down the hill instead of across the hill facing the sun).  It was great fun, the guide was very knowledgeable and entertaining, and fun was had by all.

Now let's get back to growing grapes.

March has arrived and winter is over

White grape vines still asleep. 

Red grape vines showing signs of life.


It is the 12th of March and winter hardly affected us this year. We had a few days of sleet and hail, lots of rain and wind, but very little snow and frost. It was generally mild the whole way. We did have about a week of cold weather that has just passed when there was frost on the grass so hopefully the much needed snap will have done its duty on insects and sleeping plants.

This week, warm dry weather has arrived. Lots of shrubs and flowers are budding. But the plants in the vineyard are still asleep. It's our first winter and I am anxious about whether the plants survived and if they will produce this year. I am excited about seeing them grow to the height of the stakes Alex erected. He wanted to buy more plants already but I stopped him until we see what happens in this first year.

The strongest El Nino on record and the warmest February ever are wreaking havoc throughout the world but mostly in the Pacific. There was little snow in Europe and we did not go skiing, opting to celebrate our 20th wedding anniversary and Alex's 60th birthday with friends and neighbors. I gave Alex a drone for his birthday so hopefully he'll manage to get some footage of the vineyard and we'll even be able to spot some of the plants from up high.

In the meantime, we've been starting lots of plants in the greenhouse and have prepared the vegetable beds in the garden. Alex even moved the lawn yesterday.  The climate report for Ireland was issued by Met Eireann last week and the effects are already noticeable. Our average temperature is 0.8 degrees higher than 100 years ago. The extremes are expected to get extremer. Let's hope that bodes well for our little vineyard overlooking the Holy Mountain and Clew Bay. Our guard cats certainly enjoy it.

One guard cat on the alert.

The harvest


Our first grapes.


White grape vines more robust
Red grape vines produced fruit

I harvested my first grape yesterday. It was pea sized. It was delicious. Sweet and juicy. Gorgeous deep colour. Thick protective skin. It was such a treat. We had not expected a 'harvest' in the first year.

Well, okay, it's not really a harvest. It's more of a tasting. Only the red grape vines produced fruit. The white vines grew more robustly than the red vines, but the red vines were the only ones that fruited.

At least we know it can happen  -- that grapes may form and ripen in our climate.


Interestingly, we had the coldest summer on record but October has been magnificent. The Azores high has blanketed Ireland and it forced Hurricane Joaquin to go south.  Yippee!  Gorgeous sunshine, gentle breeze, mild days, and cold nights. We actually have a real autumn with trees changing colours rather than just turning brown and blowing off. Perhaps climate change won't be so bad for Ireland after all.

Impact of Climate Change on Viticulture Globally

Numerous articles have been published about the effects of climate change on the wine industry and mitigation strategies are already being implemented. It is always interesting to me that man feels compelled to control his environment. That usually lasts long into the period after realization has set in that controlling it is in fact impossible and moving on is a more sensible solution. But of course, moving on from an estate that's been in the family for centuries is not a really feasible proposition.

The higher likelihood is that someone recognizes the potential and establishes competition elsewhere which eventually becomes more successful. At that point, the original estate begins to need more income and finds new crops to plant that are more suitable to the new environment. At least, that's how I imagine things to work and have read similar stories.

Michelle Renee Mozell and Liz Thach write in their recent review article, "Though wine is not essential to human survival, wine is an important product of human ingenuity." They tackle the global literature  about the impact of climate change on the global wine industry. It's that human fascination with wine that makes wine production a sacrosanct activity and may even be the impetus that gets governments on board the climate change mitigation train.

The entire range of grape growing climate zones is about 10°C globally; for some grapes, such as Pinot noir, the range is an even narrower 2C°. Many progressive wine growers have already taken steps to mitigate the effects of climate change, including cooling the grapes by misting and changes irrigation practices. But in the long run, those types of practices will be affected by availability of fresh water as we are seeing in California. Some are changing the manner in which they process the grapes into wine and others are planting new more tolerant varieties or buying up land in more favourable climates. It is surprising how aware these growers are of the changing climate compared with the naysayers in the public domain. But of course, farmers and fishermen are always among the first to notice the changes, it's just that they are infrequently asked by the scientists to share their observations. Perhaps now they will be, especially as funding for science drops out.

But there are three areas that still need research to determine optimal strategies:
  • studies to identify how plants, microrganisms and pathogens will respond to simultaneous rise in temperature and CO2 while rainfall decreases in traditional wine growing regions
  • means by which to reduce emission of the greenhouse gasses, nitrous oxide and methane, by vineyards during the production of wines
  • resource management throughout the production chain

The authors conclude, "wine's future is tied inextricably to a vital Earth and a vital population. Grape growers and winemakers must understand both the dire condition of the planet and the small, but significant, role their industry holds in the human matrix. They must seek, therefore, in a responsible manner, their proper and effective role in the adaptation to and the mitigation of global climate change. The future of the wine industry is dependent upon an effective course of action. The Romans declared, 'Vino veritas,' or 'in wine there is truth'. The simple, yet tragic, truth is the Earth's climate is changing. How the wine industry responds will determine if the industry is to survive."
