• - Plant cover. 
Plant cover of the wineries
It is the external surface of the wineries, it is completely covered by low-lying vegetation, very varied in herbaceous type and rarely subshrub. This mantle protects the wineries from rain and maintains the structurality of the complex. Traditionally it has been used for grazing sheep in this area as a control of the vegetation. The excavation of the wineries has modified the original profile of the land, presenting a stepped section, especially very visible in the Castle area.[3].
• - Zarceras. They are the ventilation ducts and point of contact with the outside. They run from the different warehouses to the outside of the winery vertically. They have small dimensions. This ventilation has three purposes, firstly, it is necessary for the elimination of carbon dioxide produced during the fermentation of the must for the production of wine, secondly as regulation of the temperature of the winery necessary in the production of wine and thirdly as ventilation to avoid humidity and the consequent collapse of the underground constructions.
• - Facade fronts.
Front facade of a winery
Built using masonry stone with some ashlar elements in the corners, lintels and door jambs. The lintels of the doors are usually made of stone (straight or arched with a voussoir) or made up of juniper wood beams. The warehouse fronts are grouped together forming a street. On some facades, a body has been built in front of the entrance to the winery, called a picnic area. The cellars have a single access hole in the front.
• - Chimneys.
Chimneys of the Baltanás wineries
Also called humerus. Their morphology is very diverse, although they can be grouped into two types: circular chimneys and square chimneys. There are different sizes depending on their use, we can find chimneys from half a meter high to large chimneys of more than two metres. Its exterior envelope is mostly built of masonry stone, although we find others with plaster coverage.
• - Downloaders. 
warehouse unloading
Also called casteras. They are independent architectural elements with a square floor plan, built in masonry stone, and have a small door made of thick juniper wood at their entrance. These elements are connected by a vertical conduit from the outside to the winepress. It is the first element used in the production of wine, since in this place the wooden carts pulled by animals were parked to transport the grapes from the vineyards, later the grapes were poured through the unloaders towards the winery.
• - Numerical signs. 
Numerical sign of a winery
They serve as an identification element of the different wineries. At the end of the century, when the winery census was carried out, the city council registered the winery numbers in blue on the top or side of the door. Currently, the owners of the wineries are changing these elements for more traditional ones made of wood or wrought metal, in some cases accompanying the number with the owners' surnames.
• - Access doors. 
traditional doors
The access doors to the cellars have a unique element, since they are not completely closed, but rather have openings to maintain ventilation in the cellars and prevent collapses. Most of the access doors to the wineries are original made of thick juniper wood, in a minority they are new doors respecting the traditional aesthetics. Other elements that we can find next to the door are small carved stone seats, where we can sit and talk.
• - Descent canyon. It is the first element of the staircase and vault (descent roof) that we find at the access to the winery. It is ahead of the natural profile of the terrain and penetrates into the subsoil. The canyon walls are usually made of stone masonry and its vault is made of juniper wood, stone slabs or stone masonry. This canyon is the width of the staircase and forms the first section of it.
• - Staircase. It is usually a single flight, straight or curved and with a very steep slope. It is excavated in the ground as a passage to the central nave, its vault is usually semicircular. The steps are usually made of earth, stone or wooden sleepers and are irregular in shape and in some cases there are landings between the flight of stairs. Currently, in the case of earth stairs, these have been covered with natural clay ceramic tiles, maintaining their traditional appearance. In some very exceptional cases there is no staircase to access the winery, since they are on a level equal to that of the street and their entrance is via a slight ramp of a few meters.
• - Armholes. These are the different naves that make up the underground framework of the winery. They are dug directly into the ground. These ships are between two and three meters wide and more than two meters high, as for the length, it varies between 10 and 50 meters. Most cellars have one or two armholes, although there are cellars with more than a dozen armholes. They are elongated in shape and are covered by a pointed or flattened vault. There are two types of armholes, on the one hand, linear in which the armholes are distributed successively and on the other hand, parallel in which the armholes are distributed around a larger main armhole. These spaces were originally spaces for the curing and resting of the wine, presenting holes or niches for the vats. Currently, most wineries have stopped providing this service and are used as picnic areas.
• - Kitchen. It is a room that has some storage rooms on one side of the stairs. It served as a place to rest and eat during the days of wine making. Some have a small fireplace and benches carved into the stone itself around the perimeter.
• - Winery. Another room in the winery is the winepress, where the grapes are pressed to make wine, although originally not all wineries had a winepress. In some cases the winepress is located at the back of the winery or in other cases it is located on the side. The winepress consists of a long wooden beam and a large stone that rises from the ground, rotating through a wooden spindle, threaded to the beam. The stone is placed on top of some wooden planks (castillete) and acts as a counterweight (lever), so that it crushes the grapes and the must falls into the basin of the winepress (well). Currently few wineries preserve the winepress. The municipality has a municipal communal winepress in which owners who do not have a winepress in their winery can traditionally produce the must. This winepress is located in the visitor reception area created in 2020.
