Sampling the Airén

I went out to the vineyard in Carabaña (Madrid) yesterday (4th September) to take samples of the white Airén grapes. First the low-down data, then the anecdotes!

The quality is incredible this year - not a single bunch that is bad in any way or infected with mildew or oidium or anything else. They are all clean and healthy. This is rather unusual, extraordinary even, as most years there are a few vines that are affected in some way.

After looking really hard for something to complain about, I can say that the animals have eaten more than their fair share this year, especially round the edges of the vineyard. perhaps because the grapes are so appetizing! Or perhaps because we haven't taken any measures at all to prevent them. Maybe next year we should hang up some shiney CDs or something.

Vine Eaten by Animals

The quantity was also looking OK. Unlike the Tempranillo, of which there was very little (see this previous post). There were also a few vines that were looking a bit weak and not very vigourous. I think that this year we definitiely have get a lorry-load of manure in.

Incredibly Vigorous Vine (Airén)

I did a semi-rigorous sample this time, ie not quick-n-dirty, but not ultra-rigorous either. Looking through the refractometer, I got a probable level of alcohol of 11.3%. And using the mustometer, 11.5%. For the last 8 years we've always harvested when we get a probable level of 12%, and we're going to do the same this year. If the weather stays nice-n-hot-n-sunny all week, we'll probably harvest over the weekend, after doing another few samples during the week.

Nice Bush, Weak Vine (needs manure)

This time I managed to get out to the vineyard quite early, at 9:30, so it was nice-n-cool! I saw a couple of rabbits eating the grapes but they were too fast for me to take a photo. I remembered to take a pair of socks this time, but forgot my shoes! In Madrid, I usually wear sandals from April, and put away all my socks and shoes till about October - except socks and shoes for working in the vineyard/bodega, but for some reason I stored these ones too and haven't got round to fishing them out.

I also forgot to take a container to hold the grapes that I was picking! I was thinking of what to do, as there was absolutely nothing in the car that I could use. Then I saw something white in the middle distance lying among the vines, and it looked like some litter (shock, horror) so I went to investigate. And was it not a plastic bag! Perfect for holding samples!

Then I went to the bodega and crushed the grapes and did the analysis. My last task of the day was to stick some labels on a lot of wine that we bottled a few months ago. It was the Garnacha 2010 with about 4 months in old oak. Only 4 months and old oak so that the wine doesn't get dominated by the oak flavours and keeps its original aromas and tastes. Just enough to "round it off" a little.

I printed the labels myself, as it would be too expensive to do proper labels at a printers - there are only 300 bottles of this wine (267 bottles as of yesterday!).


Even though a barrel in theory holds 300 bottles (225 liters), in practice we only get about 290-295, because the bottom always contains too many lees to bottle. Especially in our case, as we don't filter our wines. I've only sold 4 of these bottles so far, so that means we must have drunk about 20 in samplings and tastings!

Our Bottle Rack

Our 'bottle rack' is a bit precarious to say the least! It consists of plastic crates piled up 3-high in a tiny space between the wall and the oak casks in the barrel-room. At least the temperature is good!

Pre-Harvest Sampling (Tempranillo)

This morning I was in the vineyard in Carabaña (Madrid, Spain) taking samples of the Tempranillo; and as we suspected we're going to harvest tomorrow, as the probable level of alcohol will be about 13,5º.

Tempranillo Cluster

I did a systematic sampling as opposed to a quick n dirty one! ie, I walked up and down every row and picked eithe 1, 2, 3 or 4 berries from each vine, (from different sides of the vine, from different parts of the cluster, etc) so as to get an accurate and representative sample. Quick n dirty smaples are OK during the summer to give you a rough idea, but as harvest time approaches, the more accurate, the better.

More Tempranillo Clusters

Ideally, it's best to go early in the morning to take the samples, because that way it's nice n cool and it's a pleasant task to stroll through the vineyard, listening to the birdies and picking berries! Also the temperature of the juice will be lower and so will give an accurate reading, without having to do any calculations to compensate for temperature differences (most instruments are calibrated to 20ºC). Unfortunately, I couldn't get out till about 12 noon, and it was a bit too hot for confort!

It's also a good idea to wear socks and shoes, as opposed to sandals! I usually keep socks and shoes (and other clothes and tools) in the back of the car, but this was my first trip out to the vineyard after my holidays, and so I'd completely forgotten to load up all the usual stuff.

So all in all I didn't enjoy the (90-minute) experience a lot!

Where's the grapes?

This vine (above) is near the edge of the vineyard, and all the clusters have been eaten by some animal - I suspect rabbits! Note the bottom branch - even the leaves have been eaten off it!!!

Berries eaten

Some of the grapes on this vine have been eaten also, but by a different animal. See how the individual berries have been eaten but the stem is still there.

At this point, my mobile reached its limit and wouldn't let me take any more photos :(

I really must get myself a more modern internet-friendly device, so that I can post stuff straight to the internet from the vineyard or bodega, instead of having to come home and downloading into my PC!

More news and photos tomorrow on the Tempranillo harvest.
