The cradle of winemaking


Alex and I have speculated that there must be ancient vines in Ireland because we did have early Christians here for a long time. As wine was central to their rituals, the monks must have brought along vines to plant so they could reproduce the blood of Christ. We've asked Seedsavers if they are aware, and they do apparently have some vines grown from ancient vines near monastic ruins. We'll have to visit them. 

I also had been wondering where the culture of winemaking first started. I knew that ancient Egyptians made wine and beer and cultivated the yeast Saccharomyces cerevisiae. But were they the first? Perhaps the Mesopotamians were the geniuses that created the elixir of the gods? But today, I saw an article about how the fall of the Soviet Union changed wine forever and I was drawn to investigate. 

It turns out that Ukraine's neighbour, Georgia was known to be cultivating grapes and making wine 8000 years ago. Archaeologists actually uncovered a vessel that was used to store wine and dated it to 6000 BCE. That's 2000 years before the Ceide Fields in Ireland were populated by farming peoples. Georgians claim that their region is the cradle of winemaking, and that could put Ukrainians on equal footing. 

Stalin essentially destroyed the winemaking tradition during the Soviet era, forcing farmers to join collectives that focused on cheap food production of mediocre quality, not like that of their winemaking expertise. Wine was considered elite, a drink for the royalty not the proletariat. Yet somehow, people managed to preserve some of the techniques and after the fall of the Soviet Union, restored the remaining vineyards for a new era.  I'll need to research their methods in greater detail as they must have farmed organically. 

We've had Bulgarian wines at our favourite restaurant in Westport, Sage. And they are top quality so I am now eager to sample more wines from the countries of the former Eastern bloc. Let the adventure begin.

Poles are in


It looks like we have planted a field full of telephone poles, which will serve as the uprights in our trellis arrangement for the vineyard. The vines are doing well and it is encouraging that we have not only Rondo but also a few Chardonnay and Pinot Noir clusters. The Pinot Noir is surprising as this is only their third season. The Albarino aren't even considering it yet. And the Solaris is seriously disappointing again. 

I am concerned about this week's heat wave and lack of rain. An entire week of near 25C temperatures and no rain. That could put a serious damper on grape development. Although the heat might help and there is water below the surface as we saw in the holes that were dug. Fingers crossed.

Progress toward trellises

 

Poles waiting to go in. 

Holes are dug, the top of the field is levelled, the gorse has been pushed back, and the poles are ready to go in. Two of the holes are filling with water. Small wonder after the heavy rain we had several days ago. But they are not where I expected them. I expected them mid-field in the area where we lost several Solaris and Chardonnay vines, we thought due to water pooling. Perhaps we have hit a spring?

Anyway, it's really exciting to have the wild concept vineyard turn into the real deal. 


Spacing of holes.

Levelling the slope for safety.

Chardonnay and Solaris vines looking righteous!

It's quite the view over our lttle vineyard.

Poles all laid out for Ghostie to inspect. 

Very neatly drilled.

July weather


So July ended with the same rainfall as last year but 1.6 degrees cooler. Note that August 1, in one day, we had almost as much rain as we had the entire month of July. That's caused the grapes to swell rather quickly and they are noticeably bigger today than on Saturday. 


Meanwhile, Cathal Keane has arrived to begin work on the construction of the trellis structure that will support the remaining vines as they mature. Today, he is digging the holes for the uprights -- telephone poles discarded as they are replaced in our area. Tomorrow, they begin cementing in the poles in the holes. It's a big job.
