Monthly climate stats

 


As I already reported, Met Éireann has confirmed that May was officially the hottest May in recorded Irish history. The rainfall amount was higher than average, but not as high as it was last year. The temperature was 1.2 degrees C higher than the LTA. 

August proved more average. Rainfall was slightly higher than the LTA, temperature was somewhat higher, and soil temperatures were slightly higher than normal. Otherwise, it was uneventful.

Time to harvest?


I had a few moments yesterday to run up to the vineyard and test the Brix levels of our grapes. I grabbed the refractometers and started squeezing grape juice. The readings from three different areas of the vineyard were:

Rondo

  • 20            1.080
  • 16            1.065
  • 17            1.070
Solaris
  • 19.4          1.075
  • 16.0          1.065
  • 22.0          1.093

What a relief that we can wait a few days to harvest. 

Last week, we had more visitors, three brothers from Aghagower, one of whom, Brendon Edgeworth,  lives in Australia but wants to plant a vineyard on a plot he inherited here. They are very nice. I hope he does plant. The more the merrier. 



And Met Éireann today confirmed that this year was the warmest year in Ireland on record.
