Regenerative Viticulture Series #3
The Practicalities of Regenerative Viticulture with Dan Rinke and Luke Spalding

Dan Rinke consults vineyards, orchards, wineries and cideries looking for support in converting to regenerative farming and low intervention wine making, with Art+Science+Cider+Wine Agronomy. His winegrowing career began with university studies in viticulture and plant science. After working at several vineyards in California, Dan took the position as Winegrower (manager/winemaker) at Johan Vineyards, an 88-acre certified organic/biodynamic, dry farmed, and minimally tilled vineyard/winery in Oregon. Dan speaks and consults internationally about implementing regenerative approaches to improve the ecology and profitability of the vineyard.

In this session, Dan is in conversation with Luke Spalding, manager of the beautiful Everflyht Vineyard in Sussex. Luke and Dan cover a real range of topics, with a focus on more on-the-ground implementation of regenerative viticulture methods. They dig in to the practicalities of alternative inputs, building habitats for your ecosystem cleansers with ramial woodchip piles, learning from sap analyses, micro-nutrients, and wood chip applications. We learn about implementing no-till in a vineyard, cover crop mixes, and the liquid carbon pathway to name a few! Dan also shares his key tools for a fully organic and biodynamic approach and some of the theory behind why those approaches work. Watch below to learn from Luke and Dan’s fascinating conversation.

An audience member did also ask a question about iron deficiency in their  soils and the answer to this wasn’t recorded – as a quick summary Dan and Luke spoke about working with biology in a number of different ways: using humic substances to open up the iron availability; potentially encouraging certain plants or ‘weeds’ that mobilise iron; potentially using sheep to bring iron into the system; and trying to encourage microorganisms that mobilise iron. There was also suggestion of considering what is blocking the iron and managing for that as well.

Regenerative Viticulture Series #2
Regenerative Experiments on a UK Vineyard with Regen Ben

RegenBen is an agronomist, turned farmer, turned regenerative agriculture obsessive! Ben uses biological, peer-reviewed methods to produce low intervention crops, with a clear focus on diversity and experimentation. He is keen to put fun back into farming, and share his learnings as he goes. Ben is BASIS & FACTS certified – it was through doing his Nuffield Scholarship in 2016 that he had his eureka moment, realising regenerative agriculture is a crucially different way of understanding farming.

This conversation with Ben focuses on experiments on his plot of vines, and successes he’s had with regenerative methods across his whole farm. We learn about why Ben identifies ‘regenerative’ farming as a departure from both organic and conventional thinking. He talks about the importance of diversity in regenerative systems, why everything comes back to soil health, under-vine companion cropping, how to address compacted soils and the role of micronutrients in producing quality crops. We learn why, when, and how to use sap analysis, and what to look for in your results. A real range of topics were covered in this session, so there should be learnings for all levels of people interested in regenerative viticulture – from seasoned winegrowers to curious beginners!

Sectormentor helps link soil health to vine productivity – Adam Foden at Gusbourne Estate

Gusbourne Estate spans across two vineyards, one in Kent and one in West Sussex, planted with Chardonnay, Pinot Meunier, and Pinot Noir. Their growing ethos is low intervention, allowing nature’s processes to work.

The Gusbourne approach to winemaking is no different – keeping intervention to a minimum to ensure maximum expression and terroir in each bottle. Gusbourne wines have won several international awards, and they are the only three-time winners of the IWSC English Wine Producer of the Year. Adam Foden looks after the vines at the Gusbourne Sussex site.

Sectormentor has empowered Adam to link soil health and vineyard productivity:
 
“Our vines were really struggling in certain spots and we couldn’t figure out why. We sent off soil lab tests and all the indicators were good. We even had the previous farmer out to see if he had any ideas of why certain spots weren’t doing well. It was only after I dug some holes and recorded my observations and overlaid that with other info in Sectormentor that I realised it was the soil structure that needed attention. We were just looking at a compaction issue. We had ordered a load of Magnesium which we were about to apply at a very high rate – it’s great that we figured out the real problem before spinning all of that. We saved ourselves the time and repercussions of overfeeding with Mg. Instead we did some subsoiling in the area and put in mixed cover crops to improve our soil structure.”
 
“I’m very excited to get more into the soils side of it going forward. Soil is something I hadn’t paid loads of attention to even though my background is in horticulture. I never really got down and right into the detail of it, which is what I’m excited about doing. Especially witnessing this compaction issue – that is going to lead on to a regular program of soil maintenance. So we are excited to use the soil side of app over next few years, plotting how that gets better (or worse) as we go ahead.”

Sectormentor frees up Adam’s time and makes collecting information much easier for him and the whole team:

“Sectormentor really does free up my time. Previously I’d have a notebook in the field, and then had to spend 2-3 hours in the office making a spreadsheet with a formula from my notes. It’s a joy to be able to have this all done immediately – you just enter a phenological date and it’s all done, and so easy to use and accessible. It’s become second nature. Inflorescence counts are so easy now – we gave our earliest yield estimate ever this year to the winemaker by the end of June. Usability is brilliant on it, I’ve found it really comfortable to use, and everyone in the team has had a go, there is a whole spectrum of abilities using it.”

“We never really did pruning weights in the past as it felt like too much hassle, but now we’re starting to record them in Sectormentor, and it’s so easy. In some places I’ve been worried we’re stretching the vines too far, so now we’ll be able to see if that’s the case.”

Adam also finds Sectormentor helps to easily share observations with the whole team:

“We had similar information in the past but it sat on many different files, and different people move the files around so you can never find what you’re looking for. Merging all this information into one place means we can easily look at it and everyone is on the same page. As face to face meetings are hard at the moment, I can still easily discuss observations with the team – we know we are both looking at the same data.”

We’re excited to see how things progress at Gusbourne, and particularly how Adam’s soil monitoring journey develops. In response to the compaction issue, Adam has subsoiled and added in a cover crop mix. It will be interesting to see how this affects the Sectormentor soil test results going forwards.

Matt Strugnell at Ridgeview Estate


Ridgeview Estate is an award-winning vineyard just to the north of the South Downs in East Sussex. Ridgeview are at the forefront of English sparkling wine production, and ship their delicious wines around the world, having won several international wine trophies in the process.

Matt Strugnell is the viticulturist responsible for managing the vines at Ridgeview, as well as their many partner vineyards – with 20-odd years of grape growing under his belt. Matt is certainly not your typical data geek, but early on he learnt that attentively monitoring vines and being as pro-active as possible in the vineyard is key to harvesting the best quality grapes. He tells us:
 

Sectormentor helps Matt keep things organised 
 
“A big chunk of our vineyard information is now in one place, which saves me so much time. Now, at a glance I can see how the season is progressing so far and how it compares to past years.” 

Visualising his data also helps Matt to plan for the season ahead

“Some people like seeing lists of numbers, but I prefer visualising things on a graph or chart. Using the Sectormentor tools has made it easy to compare different years side by side on graphs which has been really useful for forward-planning. Pretty early on I realised collecting key information about the vineyard is vital so you can plan well ahead and get your timings just right. 

A good example of how it changed my thinking: I had an inkling for a while that flowering and harvest dates were very related but all the information was spread across so many different spreadsheets it was very difficult to compare year to year. With the Phenology Tool that has changed – I can immediately see there is an incredibly consistent relationship between flowering and harvest dates over many years, for each block. I now feel confident that on the day of 50% flowering I can pick up the phone to our contractor and let them know which week we will need a harvesting team – ensuring I’m booked in well ahead of time.”

We’re excited to see how the growing season progresses at Ridgeview, and how their key phenological dates continue to evolve year on year.
