The Book of Household Management by Mrs Beeton

Often and erroneously referred to as Mrs Beeton’s Cookbook, The Book of Household Management has a great deal more to it than just recipes. A portion of the book is set over to the duties of staff, including those responsible for the cellar:

2163. ...but the real duties of the butler are in the wine-cellar; there he should be competent to advise his master as to the price and quality of the wine to be laid in; "fine," bottle, cork, and seal it, and place it in the binns. Brewing, racking, and bottling malt liquors, belong to his office, as well as their distribution. These and other drinkables are brought from the cellar every day by his own hands, except where an under-butler is kept; and a careful entry of every bottle used, entered in the cellar-book; so that the book should always show the contents of the cellar.
2164. The office of butler is thus one of very great trust in a household. Here, as elsewhere, honesty is the best policy: the butler should make it his business to understand the proper treatment of the different wines under his charge, which he can easily do from the wine-merchant, and faithfully attend to it; his own reputation will soon compensate for the absence of bribes from unprincipled wine-merchants, if he serves a generous and hospitable master. Nothing spreads more rapidly in society than the reputation of a good wine-cellar, and all that is required is wines well chosen and well cared for; and this a little knowledge, carefully applied, will soon supply.
2165. The butler, we have said, has charge of the contents of the cellars, and it is his duty to keep them in a proper condition, to fine down wine in wood, bottle it off, and store it away in places suited to the sorts. Where wine comes into the cellar ready bottled, it is usual to return the same number of empty bottles; the butler has not, in this case, the same inducements to keep the bottles of the different sorts separated; but where the wine is bottled in the house, he will find his account, not only in keeping them separate, but in rinsing them well, and even washing them with clean water as soon as they are empty.
2166. There are various modes of fining wine: isinglass, gelatine, and gum Arabic are all used for the purpose. Whichever of these articles is used, the process is always the same. Supposing eggs (the cheapest) to be used,—Draw a gallon or so of the wine, and mix one quart of it with the whites of four eggs, by stirring it with a whisk; afterwards, when thoroughly mixed, pour it back into the cask through the bunghole, and stir up the whole cask, in a rotatory direction, with a clean split stick inserted through the bunghole. Having stirred it sufficiently, pour in the remainder of the wine drawn off, until the cask is full; then stir again, skimming off the bubbles that rise to the surface. When thoroughly mixed by stirring, close the bunghole, and leave it to stand for three or four days. This quantity of clarified wine will fine thirteen dozen of port or sherry. The other clearing ingredients are applied in the same manner, the material being cut into small pieces, and dissolved in the quart of wine, and the cask stirred in the same manner.
2167. To Bottle Wine.—Having thoroughly washed and dried the bottles, supposing they have been before used for the same kind of wine, provide corks, which will be improved by being slightly boiled, or at least steeped in hot water,—a wooden hammer or mallet, a bottling-boot, and a squeezer for the corks. Bore a hole in the lower part of the cask with a gimlet, receiving the liquid stream which follows in the bottle and filterer, which is placed in a tub or basin. This operation is best performed by two persons, one to draw the wine, the other to cork the bottles. The drawer is to see that the bottles are up to the mark, but not too full, the bottle being placed in a clean tub to prevent waste. The corking-boot is buckled by a strap to the knee, the bottle placed in it, and the cork, after being squeezed in the press, driven in by a flat wooden mallet.
2168. As the wine draws near to the bottom of the cask, a thick piece of muslin is placed in the strainer, to prevent the viscous grounds from passing into the bottle.
2169. Having carefully counted the bottles, they are stored away in their respective binns, a layer of sand or sawdust being placed under the first tier, and another over it; a second tier is laid over this, protected by a lath, the head of the second being laid to the bottom of the first; over this another bed of sawdust is laid, not too thick, another lath; and so on till the binn is filled.
2170. Wine so laid in will be ready for use according to its quality and age. Port wine, old in the wood, will be ready to drink in five or six months; but if it is a fruity wine, it will improve every year. Sherry, if of good quality, will be fit to drink as soon as the "sickness" (as its first condition after bottling is called) ceases, and will also improve; but the cellar must be kept at a perfectly steady temperature, neither too hot nor too cold, but about 55° or 60°, and absolutely free from draughts of cold air.

She also explains the correct way of opening wine and champagne:

2192. In opening wine, let it be done quietly, and without shaking the bottle; if crusted, let it be inclined to the crusted side, and decanted while in that position. In opening champagne, it is not necessary to discharge it with a pop; properly cooled, the cork is easily extracted without an explosion; when the cork is out, the mouth of the bottle should be wiped with the napkin over the footman's arm.

Now you won’t find any of that in Nigella...
