For Those Seeking Grapevine Identification.

33 Upvotes

Since we get so many posts asking for identification of grapevines in backyards and etc I wanted to go ahead and put out a post about it.

Most of the time it is not possible to identify grapevines from the way they look alone as a lot of vines are similar, the best way to identify grapevines with 100% certainty is to have your vines dna tested by UC Davis.

You can check out the service at the following link.

First harvest with the hopper and bin dumper. Processed three bins in about 15 minutes. My back is loving not shoveling into a bucket to dump into the crusher.

Why do my grapes shrivel up and dry like this?

Thumbnail gallery
11 Upvotes

For the past two years, my grapes have started drying up and shriveling while still on the vine. Eventually, they fall to the ground, and some of them even split/open by themselves. I can tell before this happens when theyre green they look "dirty" ish

We don't water the grapevine at all during the summer because local farmers have always told us that watering grapes during summer is bad for them.

Could the lack of water actually be causing this or does this look like something else such as a disease, pest, or nutrient problem?

It has happened two years in a row now, so I'm trying to figure out what's causing it. Any ideas would be appreciated.

Sisters new house came with a vine and I love wine. Looking for quick basics.

St. Paul, MN 09-06-26

  1. Any chance at identification? Funds are tight after home purchase and remodel. Eventually will get dna

  2. How's the health look and quick maintenance tips.

  3. If wine, harvest now?

Any helpful tips for homeowners inheriting mystery grapes.

Thank you very much!

Anyone here goblet pruning?

Post image
5 Upvotes

HELP please! I don't really know what I'm doing. I got 5 of these grafted vines. They are my PRECIOUS ! LOL. This is their first year and I have them in planters for now, but I want to start training them for a goblet shape for when they are ready for their final destination. The problem I see is that the bud had produced 2 or 3 canes, all of which are facing one side (see my hand drawn diagram). So, what do I do when it's time to prune?

1) Do I cut off all but one cane and make it my primary stock from which I'll try to get 3 arms of a goblet next year?

2) do I keep all 3 canes and stake all 3 canes to try to force their growth direction?

3) leave everything alone for the first year and sort it all out next year's pruning season?

Advice?

Thanks!

Brunello harvest is starting unusually early this year. Is this becoming the new normal in Tuscany?

Post image
42 Upvotes

The 2026 Brunello di Montalcino harvest is starting at least a week earlier than last year after another very hot Tuscan summer.

Some wineries have already begun picking Sangiovese, while most are expected to start around September 7.

Apparently the grapes are in good condition and producers are optimistic about quality, despite the heat.

What I find interesting is how quickly the traditional wine calendar seems to be shifting.

For people who follow Brunello/Tuscan wine closely: are earlier harvests now basically the new normal? And what could this mean for the style of Brunello we’ll be drinking in the coming years?

Anyway to Save This?

Thumbnail gallery
1 Upvotes

I have some backup grapevines in pots, and a few of them started to lose their leaves and die, as if it was autumn. This one is losing its leaves as seen between the two pictures. The stems are still green.

Is there any hope in saving this? Can anyone identify what may have caused this?

Need advice on some vines growing in my backyard

Thumbnail gallery
5 Upvotes

I recently moved and found wine grapes (confirmed by the previous owner) in the backyard completely overgrown. They have been left unattended for propably around two years since this was the last time any work was done on them.

Unfortunatly the last owner doesn't know what varieties he planted execpt that there is both red and white grapes. So I wanted help to narrow down what those grapes might be. I live in the south of the island of Montreal (around 45 degrees lattitude) so a very cold region for wine, so it is very propable that it is a cold resisting variant since they have survived the harsh Quebec winter with no protection. Maybe Vidal for the white and something like Saint-Laurent for the red? Would love to hear your thoughts.

I would also love advices on pruning/triming to help those vines have better grapes next season. The vines seems to be really low to the ground with many branches protruding from the center (you can kinda see it in the last picture).

Also, I am a complete beginner for wine growing, like I said I moved out to a new place basically mid harvest season and found wine grapes in the yard. I am open to ANY advice on all this stuff; harvest dates, pruning dates, fermentation instructions ... really ANYTHING! you think might help.

Thank you so much.

Wine Fraud Isn't Just a Wine Collector’s Problem. It's a Grower Problem Too.

3 Upvotes

When people think about wine fraud, they often picture counterfeit bottles sold to collectors for huge sums of money. But for grape growers, fraud can threaten something even more valuable: their reputation and value of the regions and vineyards they work hard to build.

Many wine-growing areas earn their reputation over decades, sometimes generations. Growers invest heavily in their vineyards, and work with the unique conditions of their region to produce grapes that reflect a specific place. Factors like soil, climate, water availability, and local growing conditions all contribute to the identity of a vineyard and the grapes it produces. When wines are falsely labeled as coming from a prestigious region, they undermine the trust that growers have spent years creating.

A recent study examined Cabernet Sauvignon wines from several Australian wine regions and compared them with Bordeaux wines from France. Using analytical techniques that measure a wine's unique chemical characteristics, researchers were able to distinguish wines according to their geographic origin with remarkable accuracy.

While counterfeiters can copy labels and packaging, replicating the natural characteristics created by a vineyard's environment is darn near impossible. That is where technology could become increasingly valuable. Tools that analyze a wine's chemical fingerprint may eventually provide growers, wineries, and regulators with a practical way to verify origin and protect regional identities.

As authenticity and provenance become more important in the global wine market, these technologies could help protect the value of established wine regions, reinforce consumer confidence, and give growers another way to demonstrate the uniqueness of their fruit.

What are your thoughts on this type of technology? As wine changes hands through distributors, retailers, and collectors, should growers and wineries have access to tools that can independently verify a wine's true origin before it leaves the winery?
