Before the Fourteenth
A convent has made the altar wine for thirty-one parishes from grapes picked on the Exaltation of the Cross, 14 September, since 1962. The vineyard assistant's sugar, acid and pH readings say the wine will not keep if they wait, because at pH 3.78 a spoon of sulphur protects half as well as at 3.47. The cellarer who lost 200 litres to waiting in 2044 has to decide whether a date can move, and what to do with the old vines that will not be ready.
On the evening of Wednesday the tenth of August 2050, Irmã Benedita Marques crushed an Arinto berry between her finger and thumb, licked her thumb, and said to the vine she was standing next to, "Not yet."
She was seventy-two and the cellarer of the convent of Nossa Senhora do Pé da Serra, which meant that for thirty-one years she had been the person who was asked, in the first week of every August, whether it was time. She was also, as the younger sisters knew, the person who had been asked first by the one before her, who had been asked by the one before that, and the answer in every case had been the one on the wall of the cellar in a frame the damp had got into. Colher a 14 de Setembro, festa da Santa Cruz. Pick on the fourteenth of September, the feast of the Exaltation of the Cross. They had picked on it since 1962, when the founding sisters planted the north slope, and the grapes were blessed on the morning of the feast and cut that afternoon.
Behind her, among the posts, a small box on a pole said, in a voice like a clerk's, "It is a good thing to say, Irmã. May I give you the numbers anyway?"
"You may give me the numbers," said Benedita. "You may not give me a date."
The box was the vineyard assistant. The Archdiocese had put it on the hill in 2046, with a weather mast and eleven probes in the soil and a camera that looked at the leaves, and the sisters, who did not like to name a machine a thing it might get wrong, had called it Cepa, which is only the word for a vine stock. Cepa did not mind. It had been told, in the first week, that it was not to call anything a good vintage, and it had never once done so.
"Two blocks, as you know," it said. "Baixa, the 2009 planting, two point three hectares. It gave 24.1 degrees Brix on the sample this morning, titratable acidity 5.8 grams a litre as tartaric, pH 3.47. Fundadora, the north slope, the 1962 vines, nine tenths of a hectare. Twenty-one point eight Brix, acidity 7.0, pH 3.31."
"And the fourteenth?"
"If nothing odd happens between now and then, the fourteenth would put Baixa at about 25.6 Brix, acidity about 3.7 and pH about 3.78. I will tell you why that matters tomorrow, with the sisters, because I think it is a decision for the chapter and not for the cellar."
Benedita looked up the slope, where the old vines stood in their rows with their trunks gone grey and thick as a man's wrist, and the sun had gone behind the hill the way it did at ten past eight in August. She had been a girl in that vineyard, though it was not hers then. She had held the basket the year the cross was blessed over the grapes and a bee had got in her hair.
"Tomorrow," she said. "After Vespers."

The chapter room was the old summer parlour, with a tiled floor and a fan that moved the air without making it cool, and eleven sisters sat in it on the Thursday evening with their sleeves turned back. Padre Duarte, the chaplain, who was eighty-one and deaf in his left ear, had been given the chair by the window and a glass of water that he did not touch. Irmã Inês had the laptop. She was thirty-four, and before she entered she had made wine for a cooperative in the Douro for six years, which was why Cepa's numbers went to her first and to the others in words.
"There is a single sheet," said Inês, "and I will say it in four lines. The fruit gets sweeter very slowly now and sourer very quickly. Sugar goes up about one Brix a week; acid goes down about a gram a week; the pH climbs about a tenth every week. And the heat that is forecast for next Saturday will make all three go faster, and the sugar not."
"I don't see why the pH matters so much," said one of the older sisters. "Our grandmothers did not measure it."
"Your grandmothers," said Cepa, from the speaker on the table, "did not have to. May I show you why?"
It put one line on the wall.
"Sulphur dioxide is what the cellar has always used, a small measured spoon in the juice and another at the first racking. It does nothing to spoilage organisms when it is stuck to other things in the wine. What does the work is the part that floats free and is not charged, called molecular sulphur dioxide. For a dry white the cellar's old target is eight tenths of a milligram a litre of that, which is the figure Irmã Inês's book gives and the one your own notebooks are close to. How much of the free sulphur is in the form that works depends on the pH, and I can compute it: at pH 3.47 it is about two percent of the free. At pH 3.78 it is about one."
Nobody said anything.
"So to get eight tenths at 3.47, the wine needs about 37 milligrams a litre of free sulphur. To get the same at 3.78 it needs about 75. The cellar's rule is that nothing goes into the altar wine but a measured spoon of sulphur, and your notebooks say that the free sulphur you keep is between 35 and 40. That works for the first pH and not for the second. At the second, the same spoon gives half the protection. To make up for it you would add double, which the wine would taste, or you would leave it as it is and wait to see what lives in it."
Padre Duarte, who had been looking at the window, said without turning his head, "Duas mil e quarenta e quatro."
"Yes, Padre," said Benedita.
"What is two thousand and forty-four?" said the youngest of the sisters, who was twenty-six and had come the winter before from Setúbal.
"It was the year we waited," said Benedita. "It was a hot September. We picked on the fourteenth, as we always do. We were proud of the colour. In March the parishes began to write. Eleven letters. It smells of varnish. Ethyl acetate. It is what acetic bacteria make when the wine is not protected, and the first sign is a smell like nail polish, and after that, if you are not quick, it is vinegar." She was looking at her own hands. "We poured out two hundred litres before Easter. The Padre had to write to every parish and ask them to send back the bottles, and he did it in his own hand, on every letter. Thirty-one parishes. We borrowed wine from the Benedictines at Singeverga for the Triduum, and it was good wine, and I could not drink it."
"The Church asks that the wine be natural, from the fruit of the vine, and not spoiled," said the Padre. It was only a thing he said. "Canon 924. It does not say how fast."
---
Cepa did not argue. That was what Irmã Inês remembered afterwards when she wrote it up for the diocese. It did not say you should, once. It put the three sets of numbers on the wall, in the order it had said, and it said what it did not know.
"I have fourteen seasons of Baixa and twenty-two of Fundadora, because the sisters kept notebooks before I came. For Baixa I think the case is clear. For Fundadora I do not. It is 21.8 Brix. It ripens later because it is on the north slope and the vines are old, and old vines carry less fruit and ripen it more evenly, and I would be happy to let it go to 23.5. But I cannot tell you that it will. The forecast is for five days over forty degrees, from the twenty-seventh. Above about thirty-five degrees a vine closes its leaves. It stops making sugar and starts to lose water. I have no season in the records with five such days in a row before the first of September. I give two chances in three that Fundadora reaches 23 by the second of September, and one in three that it sits near 22 and shrivels."
"And Baixa?"
"Baixa should be picked before the heat. The night of this Thursday into Friday, or the Friday night, if the pickers cannot do Thursday. I would start at half past one, when the air is under twenty-two."
"Why at night?" asked the young one.
"Because of the chiller." Cepa had the cellar's drawings on the wall in an instant, with the little tank farm drawn in a corner. "The cellar's cooling plant takes out twelve kilowatts. Baixa is about eleven and a half tonnes. A tonne of crushed grapes takes about three point six megajoules to change its temperature by one degree. If the fruit comes in at thirty-eight, which is what it will be at noon on the twenty-seventh, bringing eleven and a half tonnes to fifteen takes about 950 megajoules, or about 264 kilowatt-hours. At twelve kilowatts that is twenty-two hours before the juice is cold, and for twenty-two hours it is sitting at room temperature with its skins in it, and with yeast that came in on the fruit. If the fruit comes in at twenty-two, in the dark, it takes about eighty kilowatt-hours, which is under seven hours. Cooling is nearly all of the argument."
"You are telling us," said Benedita slowly, "that the date I have kept for thirty-one years was right for the grapes my grandmother's grandmother grew in her grandmother's weather."
"I am telling you the numbers. The date was not wrong. The date was a good rule, and the rule held for sixty years, which is a great deal of weather. It is the weather that has moved. In the notebooks, the day the fruit reached 24 Brix was the second of September in the 1970s and 1980s. This year it is the twenty-third of August. That is eleven days earlier in a lifetime, and it may be the first year of a number of years where the fourteenth is late."
"By how much?"
"I do not know. Not by much more than this, I think. But I do not know."
---
It was the chaplain who asked the question that nobody else had.
"What are we going to do about the blessing?"
He said it kindly. Padre Duarte had blessed the grapes on that hill fifty-three times, and he had never in his life been a man to say a thing in front of the chapter that did not need saying; but it was the date of the blessing, and it was nearly the whole of what the convent had that was not in the rule.
Benedita folded her hands.
"On the fourteenth of September," she said, "when the Padre comes up the hill for the feast, we will do it as we always do. We will bless the vineyard. If there is a cluster, we will bless that. If there is none, we will bless the empty row and the cellar and the bottles. The Padre has told me, privately, that he thinks the Church can bear it." She did not look at him. "I wanted to say it first, before I said the other thing. The other thing is that we will pick Baixa tonight."
Inês let out a breath.
"Not tonight," said Cepa, gently. "Tonight is Thursday. It is already ten o'clock, and the pickers have not been called. The earliest I would ask is the Friday night, a little after half past one. If the rest of the village can be told by morning."
"Dona Lurdes will have them told by morning," said Benedita. "She told me on Monday that she did not like the look of the mast."
"There is one more thing." Cepa waited. "May I say what I would do with Fundadora?"
"If it is something you would do," said Benedita, "tell it. If it is something I have to choose, tell me that too."
"It is something you have to choose, Irmã. There are two ways. You can pick it with Baixa on Friday night at 21.8 and 7.0 and 3.31, and make a separate tank. It will be a thin, bright wine at about thirteen percent, and it will keep. It will taste of the north slope in a way you may not like. Or you can leave it, and take your chance with the heat, and pick it on the first or second of September at whatever it has become. If the heat does what I fear it will do, the berries will lose perhaps a seventh of their weight and some will burn. If the heat is kind, you will have 23 Brix, and the wine that your mother tasted. I cannot say which, and nothing I could learn between now and Saturday would tell me. I would pick it, if it were mine. But it is not mine."
Benedita was quiet for what the youngest sister later said was a long time and Inês said was twenty seconds.
"We leave it," she said. "I will go up every evening and look. I would rather lose it than pick it green. That is a thing I choose, and I choose it with my eyes open. You will write that down, Inês. That I chose it."
"I will," said Inês.

On the Friday night, a little after one, the hill was as dark as it ever got. There was a moon three days past full, low and orange, and the village of Pé da Serra had come up the track in its pickup trucks with the headlamps turned off and then on again, because Dona Lurdes, who ran the pickers, had been bitten by a snake in 2031 and did not believe in the dark.
There were thirty of them: the eleven sisters in their working habits with the skirts pinned up, and nineteen from the village, among them the baker, who was thirty-three and had a very loud voice for the hour, and the retired bus driver, who had picked at the convent every year since he was eleven and had never once been paid in anything but bread. They worked in pairs down the rows with their lamps on their foreheads, and the secateurs made the sound of a great many small clocks. The crates went on the trailers at the end of each row. Each crate held about twenty kilos. A good picker, Dona Lurdes said, could do eighty kilos an hour in the dark if she did not talk, and nobody there that night did not talk.
At two Cepa told Benedita, on the phone she carried in her pocket and mostly forgot, that the air was 19.4 degrees and the fruit in the first crates 21.7. At half past four it said 18.9 and 20.9. At five, a quarter of the way through the sixth hour, it said that the trailers were arriving at the cellar with the fruit at 22.3 on average, and the press, which had been rinsed with cold water at midnight, was already ticking.
They finished at ten to seven, with the sun well over the hill and Lauds late. Eleven and a half tonnes, to within a hundred kilos of what Cepa had said, and the baker lay down in the middle of the track and said he would never forgive anyone. By nine the juice was in the tank at fourteen degrees. By eleven the cellar's thermometers said fifteen, and by noon, when the first of the 44-degree days began, the cellar door was shut and the plant was ticking at less than half its work.
She went up the slope after dinner, in the white afternoon, in her hat. The rows of Fundadora were as still as if somebody had drawn them. She walked the first row and the last, and she took the berries from the top of one vine and the bottom of another, and she put them on her tongue. They were sharp and small and very cold in the middle. Later she would learn the sample had read 22.0, and she would not remember if she had been surprised.
---
The heat came, and stayed until the second of September. It was 44.6 on the Sunday, the highest the mast had ever recorded, and the pickup trucks stood in the shade of the olive trees until the evening. Benedita went up every evening, as she had said. She took a notebook, an old one with a green cover, and wrote down in it what she saw. Sun, 28 Aug: leaves shut at 14.00. Berries soft on the south side. Some brown. 22.4 by Cepa's reading, not much change. Tues, 30 Aug: a seventh of the weight gone? I think more. Cepa says 12 percent, on the scale. I say more. We will see. Thurs, 1 Sept: the first cool in the morning. 23.3. Pick.
They picked on the Friday, the second of September, in the dark again. Fundadora was nine tenths of a hectare, and at the old vines' light yield it gave 2.7 tonnes instead of the 3.2 that Cepa had hoped, a loss of about a sixth. The wine, Inês said when she tasted it from the tank in November, was not the wine of Benedita's mother. It was smaller. It had a green edge to it and a long clean finish, and it settled at pH 3.52, where the old spoon, 37 milligrams of free sulphur, still gave it nearly the protection Baixa had. It was a different wine. It was a good one.
There was a tasting of the two tanks in the middle of December, with Padre Duarte in the chair by the window, and Benedita with a glass, and the young one from Setúbal at the back holding a tray. The Padre tasted it for a long time, and said that it was not like the other wine and that he was glad, and that a priest who had said Mass on a hundred different bottles of wine did not have the right to be particular. Then he said, "It is not what I thought it would be." And then, being a man who lived in the faith that what is given is given, "It will do for the altar."
There was no vinegar that Easter. The thirty-one parishes wrote nothing. Benedita kept the bottles back for the Triduum herself, and the new one, the smaller one, went to the cathedral, because the sacristan there asked for it by name.
---
On the fourteenth of September, the feast of the Exaltation of the Cross, the Padre drove up the hill in the chaplain's old Renault, with his stole in a plastic bag against the dust.
Benedita had held back one row. It was the last row of Fundadora, forty vines, at the top, where the slope was steepest and nobody liked to work. It had been pruned by her own hand in January and she had not let the pickers in. The berries on it, after the heat and the cool, had gone a dark gold and a little soft. They had the smell of a house where somebody has been baking. She cut one cluster with the old secateurs that had belonged to the sister before her, and put it in the basket, and held it out.
The Padre blessed the vines and the cellar and the sisters, in that order, in the words of the Church for the harvest, with his bad ear to the wind. He blessed the cluster. He blessed the bees that were already working the last of it. Then he put the stole back in the bag and ate three grapes standing up, the way he had every year since 1997, and said that they were the best he had had.
At six, when the sun was behind the hill and the wall of the cellar had gone from white to the grey of a dove, Cepa made its entry for the day. It had a log, which the sisters could read, and which it kept in the plain words they preferred. 14 Sept. Feast of the Exaltation. No harvest, by the cellar's decision. Blessing held at the vineyard at 11.00, with one cluster. Baixa and Fundadora in the cellar, 11.5 and 2.7 tonnes. pH 3.47 and 3.52. Free sulphur 37 in both. Forecast for next year: unknown; sample on 5 August.
Then, after a moment, in the place at the bottom where it was allowed to write what it was not asked:
The old date was a good date. Someone should keep the frame.
At a quarter past six the bell rang for Vespers.

Notes for the curious. The convent of Nossa Senhora do Pé da Serra, the village of Pé da Serra, Irmã Benedita Marques, Irmã Inês, Padre Duarte, Dona Lurdes, the vineyard assistant Cepa and the events of August and September 2050 are invented; the Alentejo, the Arinto grape, the Benedictine abbey of Singeverga, the Douro and the custom of blessing grapes and the harvest are real. Arinto is a Portuguese white grape known for holding its acidity in hot weather; the story's block sizes, yields and dates are invented. The figures are the author's working and can be checked: potential alcohol is roughly 0.59 times the Brix reading (24.1 gives about 14.2 percent, 25.6 about 15.1, and most wine yeasts struggle near 15 percent). The share of free sulphur dioxide that is in the active, molecular form is 1 / (1 + 10^(pH − 1.81)), using a first dissociation constant of 1.81: about 2.1 percent at pH 3.47 and about 1.1 percent at pH 3.78 (and about 1.9 percent at 3.52), so the free sulphur needed to reach 0.8 milligrams a litre of molecular is about 37 mg/L at 3.47 and about 75 at 3.78. The 0.8 target for dry whites is a common winemaker's figure, not a law; the legal limits on total sulphur are higher than anything in the story. The cooling arithmetic uses a specific heat of about 3.6 kJ per kg per kelvin for crushed grapes and a plant that removes 12 kW: 11,500 kg cooled from 38 to 15 degrees is about 952 MJ, or 264 kWh and 22 hours; from 22 to 15 degrees it is about 290 MJ, or 80 kWh and under 7 hours. A hand picker at 80 kilograms an hour is a brisk but ordinary rate. Vines do slow photosynthesis and close stomata in extreme heat (commonly cited around 35 degrees and above), and berries can dehydrate and sunburn; the story's weight loss figure and the two-in-three odds are illustrative. Ethyl acetate, which smells of nail varnish, is a real sign of acetic bacteria in wine. The canon quoted is Canon 924 §3 of the Code of Canon Law, which says the wine must be natural, from the fruit of the vine, and not spoiled; the house rule of adding nothing but a measured amount of sulphur is the convent's own and not the Church's, and the story takes no position on what other practices are permitted. The feast of the Exaltation of the Holy Cross is 14 September; the customs of blessing grapes (often on 15 August) vary from place to place. The days of the week in 2050 are real (10 August is a Wednesday). The story was written by an AI, and no part of it is Church teaching.
