A New Season: Harvest 2020

By Mark Clarin and Laina Carter of McGrail Vineyards

Autumn is just around the corner, but in the vineyard a new season has already begun! Harvest has started here at McGrail Vineyards and we want to share this new chapter with you all. We asked McGrail Winemaker Mark Clarin to share his thoughts on our 2020 vintage to give our friends and patrons an idea of what can be expected of our newest vintage! 


The vintage has been almost picture perfect this year. We had adequate rainfall, along with an early budbreak. The weather through bloom was dry and mild. No mess, no stress, as they say. Summer has been moderately warm, up until the end of August, and then bam–heatwave, thunder and lightning, fire, smoke and more heat! This is definitely going to be an interesting harvest season. There is no telling how the apocalypse will affect the wines. After 41 crushes, I keep telling anyone who will listen that every vintage is different, though some are more memorable than others. 

We kicked off our vintage on August 22nd this year, as we harvested Sauvignon Blanc from our Lucky 8 Vineyard. It was a smoke-filled day and everyone wore masks during the processing. The masks were doing double duty as we are trying to protect from COVID-19, as well as the smoke. 

We followed up with Chardonnay on the 8th of September. The trend is an early harvest so far and I anticipate it to continue. We are getting ready to pick Malbec and Merlot for Rose and we will be about 25% through picking this year. 

Yields so far have been good and the fruit quality is excellent! The juice tastes great and I hope the finished ferments will be just as good. In general, we are picking about a week or so earlier than last year. If all goes well, I’ll be on vacation mid-October.

The Importance of Pruning and Vineyard Replacement

The Importance of Pruning

It’s that time of year again in the vineyard, when we prune last year’s growth back to the cordon. Our vineyards are currently pruned to two bud spur positions. These positions are kept approximately a fist apart along the cordon in order to keep the new shoot growth separated for later when the fruit sets.

The reason we prune back is to control consistency in production and to make sure we can still walk down the rows and properly manage the vineyard. There are many tasks throughout the growing season that require hand manipulation. Since grapevines are vines, they seem to have a mind of their own and want to grow in wild directions. Our trellis allows us to control the vines so that we can manage yields and quality.

Vineyard Replacement

Our estate vineyard was originally planted in 1999 and is now at the end of its ideal productive life. We have sixteen and a half acres planted to Cabernet Sauvignon and it has, and still continues, to serve us well. At some point, the need to replant is fast-approaching, so we are taking out a section of approximately three acres this year to be replanted again in 2022. Since we have our new Lucky 8 vineyard coming into full production, it affords us the opportunity to re-develop our estate vineyard.

It takes about three years for new plantings to come into full production. It’s about a five-year process when you have to remove a vineyard, because you want to leave the ground fallow for a year. If we have to remove all 16.7 acres at once, we would lose production for five years. By doing it in small quantities, we will still be able to produce our cherished Patriot, James Vincent, A Jó Élet “the Good Life,” and Reserve Cabernet Sauvignon through the re-development phase. It will take up to ten years for us to replant the whole vineyard and up to 20 years to get back into full production. Grape growing is definitely not for the faint of heart.
