Folding Hill Pinot Noir Orchard Block 2012

I really enjoy tasting the latest from Folding Hill, firstly because they are classic examples of the Central Otago style, which we could consider today an essential benchmark for understanding what Pinot Noir is capable of. For me, establishing some sort of taste memory for a wine such as this is vital when I come to taste Pinot Noir from Sancerre, Cheverny, the Auvergne (and even the occasional Burgundy) and so on. Secondly, the intrinsic quality here seems to me to be very high, with pure fruit, fresh acidity and confident texture; these aren’t difficult wines to taste! And thirdly because proprietor Tim Kerruish is from my neck of the woods, and even went to the same university as I did. He ended up a wine celebrity in beautiful New Zealand, while I ended up……well, let’s not go there.

Folding Hill Pinot Noir Orchard Block 2012

This is a small-scale operation, with a tiny production from just 4 hectares of vines. The winemaking is currently outsourced, but all the fruit is home-grown and hand-picked. It is 100% destemmed and fermented in small steel vats, before spending 18 to 20 months in oak. The wines are unfiltered and unfined.

Folding Hill Pinot Noir Orchard Block (Bendigo, Central Otago) 2012: Bottled under DIAM cork. In the glass this is a dark, richly pigmented wine, but there is still a fine translucency to it. It has a fascinating nose, brimming with dark fruits, with a lightly curranty character which I like, reminiscent of dried damson skins, but there’s a rich, sweet confidence as well. Some of it seems to be oak-derived, with touches of cocoa and cigar smoke, some new barrel spice giving it a sweeter edge. The palate is sweetly ripe, textured, peppery and spicy fruit, with damson skins, fresh and vibrant acids here, but with a vinous texture. An attractive, supple, very slick and yet energetic style, with lots of polish. Great potential here. 17.5/20 (January 2012)

Terroir and Yeasts Revisited

Once I learnt of it, and really began to understand what it was telling me, the concept of terroir always made sense; in essence, two different sites will always give, even though the variety and the vinifications are the same, two different wines. So a Bourgueil from Les Malgagnes will taste different to one from Les Quartiers, even though both come from the same cellar and the same vigneron. That is terroir.

Defining what lies behind terroir, however, is fraught with controversy; understanding why one site gives different wines to another seems an impossibility. We have climate, soil, bedrock, aspect, drainage and more. Should we include the winemaker? Should we include the local microbiology, either that in the soil, on the grapes or in the winery? All have been mooted.

The thought that terroir might be a yeast effect is a tempting one. After all, as far as I am aware, few agricultural products show this ‘regionality’. Please correct me if I am wrong, but a peach from one orchard tastes much like a peach from an orchard down the road, provided the variety and agriculture is the same, but two wines from fruit grown just metres apart can be radically different. The key difference between the two products is that wine has undergone a microbiological transformation, a process not relevant to the world of peaches (unless you’re into home brewing I guess).

While there is no doubt different yeasts imbue wines with different characteristics (cultured yeasts are sold on this very basis – some types are ‘neutral’, while others produce more aromatic results) I have stated before I find the idea that terroir differences might be due solely to yeasts rather an unlikely one.

A recently published paper from Matthew Goddard and team from the University of Auckland School of Biological Sciences would appear to support my thoughts, even if the authors argue it in the other direction. The authors fermented many (over one hundred) sterilised samples of Sauvignon Blanc juice with genetically diverse isolates of Saccharomyces cerevisiae from six different regions of New Zealand. They then looked at an array of volatile compounds to see if they differed from one S. cerevisiae ferment to the next, and therefore from one region to the next.

Here’s the science bit, part one. Goddard et al found that when the juice was fermented with single strains, there was some difference between the aromatic profiles of the wine that resulted. But there are three important points here: (1) this isn’t surprising; we know different yeasts produce wines of different aromatic qualities, (2) the differences between the six regions when tested with single-strain ferments was only 10% down to the yeast, so even with a single-strain ferment the aromatic differences were 90% due to other (mostly unknown) factors, and (3) the aromatics differed from batch to batch – variation between batches accounted for 7% of the differences in levels of the volatile aromatic compounds (nearly as much as the yeast-effect, which was just 10%).

With the yeast effect hardly stronger than batch variation, is it really a plausible candidate for the cause of terroir?

And here’s the science bit, part two. Because part one is not applicable in the ‘real world’ (because wild ferments involve many different yeasts all working at the same time – they are not single-strain ferments) the team also did co-ferments, with not one strain from each region, but six single-region strains mixed together. With these fermentations, there was no statistically significant relationship between the region from which the strains came and the aromatic profile of the wines. Now this might just be a problem with sample size – perhaps running the test again with several hundred more samples would solve this (yes I know that is easier said than done – this paper reflects a lot of hard work).

Even so, for the moment it appears to me that any regional ‘yeast effect’ is identifiable but small with a single strain, but this appears to be lost in the mix once you have a body of yeasts working together, as in the ‘real world’.

Perhaps yeasts do contribute something to terroir. I am open-minded on the matter, and await some convincing research to persuade me one way or the other. But even if they do contribute, this research suggests yeasts play a minor role, which would therefore seem to indicate that the traditional view of terroir as being related to the physical properties of the site still holds true. Or at least more true than it does for yeast.

Two from Folding Hill

What I expected to find when I engaged with Twitter for the first time was a lot of gossip, breaking news stories and naturally the occasional scandal. I didn’t expect to discover somebody like New Zealand winemaker Tim Kerruish.

Tim might be a resident of New Zealand now, where he tends Pinot Noir vines on the northern terraces of Bendigo Creek, Central Otago, but he is a Brit who grew up in the Isle of Man. That’s funny, so did I! Spreading his wings he went on to university, to study medicine. Another coincidence – I did exactly the same! Tim studied at Liverpool University.

Err….hang on a minute. So did I.

Sadly for me, that’s where the similarities end. Our respective periods of study at Liverpool overlapped by only a year, and I never met Tim. And shortly afterwards he hot-footed it over to New Zealand, where he now works in Emergency Medicine, that’s when he isn’t busy with his vines and his wine of course. From his 4 hectares of vines Tim gathers together enough fruit to produce just a few hundred cases of wine every year, sold under the Folding Hill label. The operation is bijou and there is clearly a focus on low intervention and high quality. His domaine is accredited under the Sustainable Viticulture Scheme administered by New Zealand Wine Growers, the fruit is picked by hand, destemmed and fermented in 30-hectolitre vats, with the cap submerged through pigeage or punched down by hand rather than pumping over. Only the best vats are selected, blended and bottled without fining or filtration, and what remains is sold off in bulk.

The wine you are most likely to encounter is the straight Folding Hill cuvée, but thre is also a special selection from the Orchard Block, a small vineyard in the lee of an orchard of old cider apple trees. Thanks to Tim I recently had the opportunity to taste both wines from the 2009 vintage. The fruit for both was harvested on April 16th 2009, and both are closed with a DIAM cork (hurray!) meaning a secure seal and zero chance of cork taint.

Folding Hill

Folding Hill Pinot Noir (Bendigo, Central Otago) 2009: Bottled under DIAM agglomerate cork. A pure, cherry-red tinge in the glass. The nose opens up over half an hour or so to reveal something very relaxed, fruit-dominated and accessible. The style kicks off as bright and strawberryish, but it soon becomes apparent that this is ripe and rich, but happily not sweet or over the top. The plummy fruit is concentrated and lightly savoury, with a little dark chocolate and mushroom polish laid on top. There’s a touch of truffle to it as well; this is certainly no simpleton! The palate has a gentle concentration with a fresh and acidic brightness, showing the mouth-watering tartness of just-ripe raspberry alongside the more savoury tones, and in the finish more challenging hints of pepper, spice and some tannic lick. Lovely stuff this. 16.5/20 (March 2012)

Folding Hill Pinot Noir Orchard Block (Bendigo, Central Otago) 2009: Like the domaine cuvée, bottled under DIAM agglomerate cork. Just 75 cases produced. This has perhaps a touch more concentration on inspection, the core of the wine a little darker, but the hue is still bright and vibrant. The fruit here is slightly more high-toned and elusive in character, but it also has that mushroom and dark chocolate character to it. The truffle isn’t here, but there are slightly wilder, more gamey feathered notes instead. Very solid and forthright on the palate, a much more reticent style than the first wine which is certainly more open and ready. This wine needs more time yet, and it says this more clearly on the finish with a seam of spicy tannin which will keep this wine going in the cellar for years. Savoury, slightly cerebral, and definitely worth a punt. 17/20 (March 2012)

All in all, two very good wines, the first for drinking now, and the second deserving of a year or two in the cellar I think (and I am sure the first could stand up to this as well). Well done Tim!
