UK Vintage 2018 Report #5 – July

As July comes to an end the weather has been so continually hot that comparisons to the famous hot summer of 1976 have moved on to comparisons with the equally hot 1937.

As I write we have just had our first prolonged bout of rain in 8 weeks which was much needed, but has only cooled the temperatures down to the low 20°C’s which would be a pretty good summer for us usually.

The vines have been getting on with their work, putting their energy in to the grape clusters and, for the most part, little pruning has been required.

July 18 Chard

Coping well with the heat and intense long sun hours, the Chardonnay continues to be the most vigorous, the MVN3 the most productive.

July 18 MVN3

My Ortega, however, hasn’t fared well at all and looks only one step away from dying off completely.

Perhaps struggling without water access, the canopies are thinning, with whole shoots/leaves turning brown in some places.  The almost non-existent crop hasn’t developed much further either, and they generally look quite sad.

July 18 Ortega

Even though temperatures are cooler this weekend and in to next week, further warm weather is on the way, with August looking to deliver much the same as July.

UK Vintage 2018 Report #4 – June

Time for a quick check in on my vines now and how they’re doing in the blisteringly warm June sunshine.  Temperatures throughout the month have been at record breaking levels, with many days hovering in the high 20’s, and nights staying in double figures.

The main activity this month has been trimming back the increasing level of vigour and growth, allowing the remaining vines to focus their energy, which will help the clusters to continue developing.

UK June Chard

Whilst the Chardonnay is progressing OK, my Ortega is looking like it is going to be somewhat lacklustre this year, and there’s limited clusters coming through for whatever reason.  It’s been growing vigorously enough, but does get a lot of attention from mites, hence the blotchy leaves in the picture below.

UK June Ortega

The lack of potential Ortega grapes is well offset by my MVN3 which is getting itself ready to deliver a huge crop, so it’s a shame that I still don’t know which variety it is.  These vines were planted one year ahead of my Chardonnay and Ortega vines and so has a little more maturity to it, which may be helping.

UK June MVN3

Whilst allowing the lack of natural water to stress the vines just enough to promote growth, occasional watering is taking place so as not to dry them out completely.  Temperatures are set to hit 30° C this weekend, and the uninterrupted sunshine is set to continue as far as current forecasts go.

Summer is well and truly here!

UK Vintage 2018 Report #3 – May

UK May18 ChardChardonnay

May in the UK has a Bank Holiday Weekend at both the start and the end of the month.  These two events, mere weeks apart, couldn’t have been more different to each other in terms of the weather conditions.

The first managed to continue the glorious early run of uninterrupted sunshine and warm temperatures that we’ve seen, whereas the latter (which has just occurred as I write) was just a touch cooler but several degrees less sunny.  There’s been mist, rain, and several prolonged thunder storms across much of the country.

To be fair, the general month of May has seen untraditionally high temperatures (generally 18-23°C) carry throughout the month in long uninterrupted periods.  It’s amazing to see the advances on the vines versus last month now that they have been exposed to a good few weeks of sunshine.

UK May18 OrtegaOrtega

Well on track despite the late April start, growth has accelerated, changing mere shoots in to fully formed trailing vines requiring early trellising, and buds have begun their transformation to grape clusters.  As per every other year, my Chardonnay and Ortega vines have bumpy leaves left from mites, whilst the MVN3 manages to escape.  As it is only a cosmetic malady it’s not too much of an issue.

UK May18 MVN3MVN3

Despite the current mist and dampness, the good news is that we are extremely far away from the May conditions of last year which saw the early development of the vines destroyed by late frosts.

The current projections for June’s weather are positive, with the sunny and warm days set to return.

UK Vintage 2018 Report #2 – April

As pondered in my previous March vines blog, some 2-3 weeks later than expected, all my vine varieties have now sprung in to life.  This was definitely hastened along by the very un-seasonal and highly unusual weather conditions that we’ve seen in April, which (sadly) arrived just in time for everyone to return to work following the Easter holidays.

UK April18 ChardChardonnay

Although the whole week in general was hot by UK standards, Thursday the 19th through to Sunday the 22nd was our ‘heatwave’, ushered in from South Africa and giving temperatures up to something like 28°C at its peak.  This gave us our warmest April day in nearly 70 years and was extremely welcome.

UK April18 OrtegaOrtega

Although temperatures are now firmly back to circa 8-11°C and carrying with it a fair share of (April) rain and cold winds, further good weather is apparently back on the way and will hopefully eliminate the usual late April frosts.

UK April18 MVN3MVN3 (currently lagging slightly behind the others)

Traditionally our early May Bank Holiday weekend usually brings with it wet weather but, as forecasts currently stand, temperatures will apparently be lurking around the 20°C mark.

Here’s hoping!

UK Vintage 2017 Report #6 – September

The last blog piece written about the progress of my vines through the 2017 season lamented the less than stunning weather seen in August and hoped for a warmer September to compensate.

Any summer renaissance however (which was promised by several forecasters) never materialised and we are now fully in to the cooler temperatures and visibly shorter days of autumn.

Here’s an update as to how things are progressing in the final run up to the harvest.

Ortega

Ortega Sept 17

Furthest along in terms of maturity, this variety is there or thereabouts ready for picking.  The leaves are already starting to change colour to autumnal brown, and I measured the Brix level of the grapes as 19 (giving a potential alcohol of 10.8%).

As a short explanation for those not familiar with growing/picking grapes, a refractometer is an essential tool for a winemaker.  You simply squeeze a small amount of the grape’s juice on to the clear end plate, seal it in and look through the viewing lens.  As light refracts through the trapped juice, the angle of refraction measures the volume of sugars present, ergo the potential alcohol.

Refractometer

10.8% potential alcohol is fair for a white wine produced in the southern UK climate.  11.5% would be perfect so I’ll try to hang on just a little bit longer for now.

Chardonnay

Chardonnay Sept 17

Probably about 2-3 weeks behind my Ortega is my Chardonnay, with a current Brix level of 16 (potential alcohol of 8.8%).  The leaves here have also just started to change colour but, unlike my Ortega, the last couple of weeks have seen the vine continuing to grow, not so much in length/height, but in density.

MVN3

MVN3 Sept 17

As mentioned last month I have seen a very poor yield this year.  This last week has seen veraison (the changing colour of the berries) start to kick in, but the Brix is still tracking at a lowly 11, which is not even on the conversion chart!

You would expect a red grape to be trailing behind the whites, and this one looks like it will need every single remaining day of the harvest if the poorer crop is to come to anything at all.

Summing up, there is once again a slight resurgence in the temperatures forecasted for next week but, as this change has been on the horizon for a good few weeks now, I will believe it when I see it.

UK Vintage 2017 Report #5 – August

As suspected, the weather this last month has been variable and pretty typical of an English summer.  Whilst it hasn’t been overly cold (temperatures have been anywhere between 16-23°C) it has been generally overcast and cloudy, and fairly muggy.

Heavy bouts of rain have punctuated throughout, with at least 2 short hailstorms here in Newbury, so the grapes have been well watered.  Only one final trim of the vine length has been needed which hopefully means that all their energy is going towards swelling the grapes.

Chard Aug17

The Chardonnay and Ortega continue to track pretty evenly with a pleasing number of good sized bunches each.

Ortega Aug17

Conversely my MVN3, which is the more established of my varieties, is having a lean year this year (perhaps due to less keen attention on my part in taming its vigour).

MVN3 Aug17

Usually if we see such wash-out weather in August we get a late summer renaissance in September.  Initial forecasts look like this may be the case but, with a Bank Holiday weekend coming up, we can never be too sure!

UK Vintage 2017 Report #4 – July

The recent weather, interspersed as it has been with some of the hottest days on record and most days hovering around the 21-22° mark, has a lot of similarity to the start of the 2016 harvest.  In terms of the progress of my vines, it couldn’t be more different.

A good portion of the reason I keep these short weather and growth diaries is to cross-check their performance year on year, and this month versus last July is a good case in point.

The 2016 vintage, although beginning with early warm weather, failed to produce a yield of any substantial size.  The temperatures pulled back somewhat in July and August and the potential crop never filled out, leaving slim pickings come October.

Back to 2017, and now that any risk of frost has been mitigated against, I’m blessed with numerous healthy and blooming bunches on both my Chardonnay and Ortega vines.

UK July17 Chard.jpg

UK July17 Ortega

My MVN3, which is usually quite a large producer (having been established slightly longer than the other vines) is actually the poorest performer at this point.

UK July17 MVN3

There’s been a good deal of cropping this month in the naturally extending length in all vine varieties, as well as significant leaf cropping in the Ortega due to the recurring issue with mite blistering to the leaves (Colomerus Vitis).  Although these mites are not harmful to the overall crop, I’m attempting to keep the soils and vines as uncompromised as possible.

UK July17 Mites.jpg

The last few days have brought significant rain, including one serious overnight storm, and damp conditions are forecasted for the next couple of weeks.  Hopefully this will serve to feed and swell the grapes just enough, without them being overpowered or diluted.

UK Vintage 2017 Report #3 – June

Once the late May frost had passed without too much incident to my vines I wrote of the promise of warm weather.  The warmth we’ve ultimately seen has been both a blessing and a curse, culminating in 2 of the warmest June days for some 40 years.

Post any minor loss of leaves to the frost I’ve been more blighted by strong winds, with both my more exposed Chardonnay and Ortega vines taking a hit and losing some potential new canes.

With a further eye on controlling the impressive early vigour of the vines I’ve cut back a good length of the extreme growth and am now thankfully in a position where I have a good number of healthy bunches beginning to form.   Potential yields for both the Chardonnay and Ortega are on a par with each other, with the MVN3 only a short way behind.

A further month of extremely pleasant and warm weather is forecasted, but I shall be glad when the current heat of 30°C drops down to a more bearable 22-24°C.  Careful watering over the next few weeks will be key to ensuring that all progresses to plan.

UK Vintage 2017 Report #2 – May

My previous growers blog left off with the expectation of a possible bad frost heading my way and, sure enough, the end of April saw low temperatures arrive in the UK.  Like most French wine regions, the south of England saw much destruction with some producers having as much as 75% of their crop affected.

Although France suffered a slower, week-long grip of bad weather, the pain-point here was the night of the 27th/28th of April, and the specific hours of 3am to 5am.  To try and curb any destruction of the early flowering I was one of those lighting small fires around my vines to bring the temperatures up even just one or two degrees.

DSC_0074

Creating this small micro-climate could well have made the difference to this year’s yields, and thankfully (very much due to this precaution), my losses were only small.  The leaves and buds that were destroyed were in between the various heat sources I had laid out and therefore at the mercy of the natural temperatures which dipped down to about -6°C.

Since then the weather has been fair with occasional rain and temperatures in the low teens, and all three of my varieties are now showing good signs of growth with clusters forming.

DSC_0069.JPG

This week has seen me start adding some additional trellising to begin to control the vine growth which, as usual, is led by my Chardonnay vines.

Forecasted for the next two weeks ahead are some glorious clear and sunny skies with temperatures in the range of 20-26°C.  Happily this means we are beyond the worst of the weather and can now look forward to a good growing season.

UK Vintage 2017 Report #1 – April

As usual, one month after the first signs of life in my Chardonnay, Ortega and mystery vines I like to kick of the yearly document of their progress.

UK17 Twit Pic

Compared to last year we have more leaf and new stem growth in all varieties, with the Chardonnay taking the lead as usual.  The weather has been very pleasant, with one early April weekend warmer than many parts of Europe, and temperatures of circa 26°c gave us one of the warmest April days on UK record.

Generally the weather has been hovering around the mid-teens celsius with patchy cloud, and there’s only been a handful of days with rain but, as I write, the vignerons of Champagne are reporting crop loss due to bad frosts.

UK17 MVN3

                                                                               Mystery Variety #3

I’ve noted at least one English wine producer worried about this hitting the south of the UK, and the forecast for the week ahead does seem to be punctuated with overnight temperatures around O°c and more rain than we’ve seen up to this point.

Here’s hoping that the good progress so far isn’t spoiled early on.
