glyphosate – ‘a gift from god’

By billn on August 13, 2018 #a bit of science

This is a very important principle.

Properly used, in the dosages recommended, there are no reputable scientific studies that point to a cancer link with glyphosate. Not yet anyway! The single study (in over 40 years of studies) that suggests a link between the two has been accused of cherry-picking some data and avoiding contrary data. That’s why there is peer review of science, not courts of law to decide such things. The recent award of almost $290 million is a travesty, sorry as the case of the individal is.

Let’s be clear about this, I don’t condone the use of Roundup where expensive wines are produced, it is not just lazy, it is indecently money-grabbing when there are so many alternative manual approaches. But this particular molecule has benefited millions, if not billions of people and animals when it comes to the production of basic foodstuffs. Monsanto are an easy target, indeed they are a deserved target for some of their approaches, practices, and some other of their products, but a CEO of that company once described Glyphosate as ‘a gift from god,’ and, so-far, there is no credible evidence to the contrary…

chardonnay – as you’ve never seen it before!

By billn on June 05, 2018 #a bit of science

Way back in 2010 I had a contact in Basel who did, and still does, some extra-ordinary work with his electron microscope. Dr Martin Oeggerli has been published worldwide by the BBC, National Geographic, Nature and so many others. See here: www.micronaut.ch

Having seen so a lot of his work with plants I asked if he would like to do the same with some pinot and chardonnay from Burgundy – we also collected some aligoté and gamay. I thought if the images were as great as I expected, then I could do a nice sideline, selling special fine-art prints of the images – they would have been expensive, but hey!

I recruited a certain David Clark, formerly of Morey St.Denis, to collect samples at flowering – and then passed on the phials to Martin in Basel.

As it turned out, for quite some time afterwards Martin was simply snowed-under with publishing work, then my own position became complicated after the company where I worked was acquired. I saw some interesting black and white images from Martin but colouration – and all such images that you see require many, many hours of colouration – was put on the back-burner and eventually forgotten – by me – but seemingly not Martin!

Today he sent me this great image – “Bill. Today, I finished a picture from a sample you originally provided back in 2010 (Chardonnay; enclosed)… hope you like it.” Now how cool is that?

We had a short conversation which I will include so that you may understand what you’re seeing:

Me: “Is that the tip from the flower, post fertilisation?”

Martin: “Exactly. To me, the stigma looks pretty fresh. I guess, it is showing the tip of the pistil (with the stigma in red) during, or just very shortly after fertilization. One pollen grain has hydrated and grows a pollen tube across the stigma. Since I am working on a project on plant tissue I was digging in the archive…”

Enjoy…

agrumes?

By billn on December 23, 2016 #a bit of science

When even a (non-French) winemaker asks me what I mean by ‘agrumes’ in my tasting notes, then I realise that I’m using a ‘too Frenchie’ term in an Anglo-Saxon context, and I need to explain. I’ve added the following to my ‘Technical Glossary‘ page:

Agrumes
Agrume is the type of fruit that can range from orange to grapefruit – and everything in-between.* An agrume desert is normally a mix of orange, mandarin, grapefruit et-cetera. Agrume reduction or ‘noble reduction‘ (as is the current phrase-du-jour) is the Roulot style of white wine reduction that (everyone is trying to mimic today) has a grapefruit-style aromatic and even flavour, yet is (technically) closely associated with a modest reduction.
*Agrume fruits: Bergamot, Bigarade, Calamondin, Chedrat, Citrandarin, Citrange, Citrumelo, Clementine, Clemenvilla, Combava, Grapefruit, Kumquat, Lemon, Lime, Limette, Mandarin, Orange, Pomelo, Tangelo, Tangerine, Tangor, Ugli, Yuzu

[launch] üllo – wine purification?

By billn on July 22, 2015 #a bit of science#accessories

ullo-1Or maybe better – ‘sulfite removal’!

I had some PR puff about this, and normally I avoid gizmos such as this, like the plague, but as a former research chemist I was interested in what the process might be.

From the website and the linked Kickstarter page it probably works like an ion-exchange resin – i.e. similar in mode to the standard filter that you may use to make your water a little more palatable, assuming you live in a hard-water area; here in Europe Brita water filters are one of major brands.

If the video is anything to go by, the filter works amazingly fast – so I expect it’s a mock-up – but I’d be really interested to see how ‘selective’ this ‘solution’ is, or whether it neuters the wine in any way. I also expect some blockage (blinding) due to the sediment in older wines – but maybe sulfites are not an issue with older bottles, so (in this case) the gizmo isn’t required. I’d also be interested to know how much volume, and of what type of wine, is required to ‘exhaust’ a filter – for instance sweet wines have much more sulfite to preserve them.

A fair question, though, is ‘how many people are really affected by this?’ I’m aware, anecdotally, that many are, and particularly for those who drink white wines, though in today’s market for ‘healthy living’ I’m sure this has great potential for sales, regardless of whether they drink Richebourg, Sauternes or Yellow Tail. Let’s see.

I assume though, that the company won’t be using the following data in their marketing campaigns, much as I know some people also have problems with dried fruit!

sulfites...

wine faults seminar 15th may in london…

It seems that half a dozen places are still open for this seminar, so if you’re both interested and available, please directly email andrea.warren at btinternet.com

“Pyrazine in the Burgundy: could it really be the ladybirds?”

Bill Nanson has had derision and support from winemakers in almost equal measure for his theory about the ailment that affects 2004 and 2011 red Burgundies, and the basis of this will be explored and no-doubt extensively challenged during this discussion. But it seems that a minority of people can taste and smell this aspect of those vintages – or is that simply because they haven’t been properly introduced to it(?) During this discussion we may find out, with four examples from very well-known and admired producers, some false positives, and some fun exhibits that may or may not support Nanson’s contention…
