Rootstock Podcast Episode Launch

 Hello Dear Growers,

Congrats to another successful harvest! It has definitely been a year to remember, and a vintage for the books. I very much look forward to tasting the 2025 vintage once it's out on the shelves.

Again, congrats, and a job well done.

I'll jump right into upcoming events and new releases.

The "Season Wrap Up" event is less than a month away. Please remember to register and join us for a look back at this memorable season. Benefits include a good day of learning, catching up with your fellow colleagues and a complimentary lunch!

"Cool Climate Crush" Podcast

The new episode is now out. 

Rootstock Insights: Selection Strategies for Cool Climate Vineyards with Dr. Jim Willwerth

Description:
In this episode I speak with Dr. Jim Willwerth of Brock University’s Cool Climate Oenology and Viticulture Institute (CCOVI). Our discussion explores the science and practical application of rootstock selection in cool climate viticulture. We highlight key factors growers should consider, recent research developments, and evidence-based strategies to enhance vineyard resilience and performance.

 Hello Dear Growers, And Happy Weekend!

Here are the Brix, Acidity and Potential Alcohol for the sampled varieties. These samples were taken around Kentville and Wolfville, so your results may be slightly different.

 

Please see the weather forecast coming up and plan your harvests accordingly. It will be a cool and wet week, so let's avoid splitting and dilution as much as possible.

COMING UP: 

Episode 2: Rooted in Resilience – Choosing the Right Rootstocks for Cool Climates

This episode explores the critical role of rootstocks in optimizing vine performance under cool-climate conditions. Join me and our guest Dr. Jim Willwerth as we discuss current research on rootstock–scion interactions, with a focus on cold hardiness, nutrient uptake efficiency, and growth regulation in variable soil and climatic environments. We also examine the physiological mechanisms that drive rootstock adaptation to abiotic stress, and how these insights inform rootstock selection for long-term vineyard sustainability and fruit quality.

I will post the link as soon as it becomes available.

Thank you all for your time this week. I am still in the field sampling. If you would like a visit or a chat, please let me know.

I hope you all have a good week ahead.

Cheers!

As promised, here are the maturity control numbers for this week.

-Firstly, the weather for the rest of the week:

I hope the harvest is going well for all of you despite the rain we had. 

Here are the Brix numbers:

I would expect the Pinot Noir and Chard to be coming off soon-if it hasn't already, with Meunier following very closely. 

Here are a few reminders.

Maturity Control: Week of 29 September 2025

 Hello Dear Growers!

Welcome to another absolutely beautiful week of fall. I am aware that there was no blog post last week, so this week, there will most likely be two. 

Firstly, here are some weather forecasts for this week (and yes, some rain is coming-maybe-we'll see on the day). The temperature will be dropping as the week continues, so please do be aware that some frost in the evening may be a possibility. We are in the thick of harvest, and by all accounts, the situation looks fantastic. I am hoping that the rain predicted for Wednesday does not impact berry integrity or quality in any significant way. 

 

Below is the final data for the season from Jeff at the Kentville Research Centre. 

Table 1.  Precipitation totals for the Kentville Research and Development Centre by month.

Month	25-Year Average (mm)	Current Year (mm)
April	81.9	93.7
May	74.0	88.6
June	98.7	50.5
July	85.9	33.0
August	91.1	13.2
September	98.8	22.3
October	115.8	0.5**

**Up to October 1, 2025

Table 2. Growing degree days and Sine degree days up to October 1, 2025.  All temperature data were recorded at the Kentville Research and Development Centre.

Single sine degree days, base of 0 °C starting on April 1		Growing degree days, base of 10 °C starting on April 1
Current Year	10-Year Average	Current Year	10-Year Average
2828.5	2781.8	1128.4	1110.0

Lastly, please see the sugar and acidity stats below. Accumulation is slowing - as is to be expected. Keep a lookout in your varieties. Some cultivars have shown signs of raisinating as we wait for the acidity to decrease.
