A Roman dolium was a very large ceramic storage and processing jar. In some wineries its heavy body was set partly into the ground; Pompeian evidence also documents dolia used for fish sauce.
A dolium (plural dolia) was a very large Roman ceramic container used for bulk storage and, in some documented settings, processing. It is not the same as an amphora: the broad, heavy storage jar belongs to a cellar or work area, while the familiar handled amphora was shaped for carrying and shipment. The word alone does not establish what a particular jar held; its archaeological setting and residue matter.
The Villa Regina complex at Boscoreale preserves a wine cellar with eighteen dolia. The archaeological park dates the villa's original form to the first century BCE and records its destruction in the eruption of AD 79. This is a specific installation, not a universal count or a capacity standard for Roman cellars.
The comparative study of Roman vinification treats dolia as engineered containers: clay composition, dimensions and shape were selected features, not incidental details. Its comparison with Georgian qvevri asks how vessel material and placement may have influenced wine. Those proposed flavour effects remain interpretations rather than direct evidence of a single taste produced by every dolium.
The dolium's mass and size made its placement part of how it was used. Where a cellar installed jars partly in the ground, the surrounding earth supported the vessel and buffered it from short-term changes in room air. That physical relationship should not be mistaken for refrigeration or a measured constant temperature. The sources do not establish a standard capacity, wall thickness or operating temperature for the type.
Wine storage is documented at Villa Regina, but Roman dolia also appear in other food-processing contexts. Chemical study of six dolia from Pompeii's so-called Garum Shop examined fish remains and compared them with the garum preparation described by Gargilius Martialis. The vessels record different batches at the time of the Vesuvian eruption. This is evidence for those six jars; it does not show that every dolium was used for fish sauce or that wine and salted fish shared one vessel.
The Roman fish-sauce vats known as cetariae were built masonry installations, a separate kind of equipment. A ceramic dolium and a built cetaria should therefore remain distinct even when both appear in evidence about garum. Matching a vessel to the process depends on the site evidence, not a broad visual resemblance.
Dolia survive as objects and as fixed parts of rooms, so archaeology can show how a large vessel related to a cellar floor and to nearby work areas. A photograph of a row of jar mouths in a floor shows the visible installation, not the complete buried bodies. Conversely, a removed jar can show its full silhouette but no longer shows how deeply it was set or how its contents were reached.
No modern maker, standard size or current acquisition route is established for the Roman examples discussed here. Their practical lesson is historical: vessels were selected and installed to meet particular storage or production needs, and their material, shape and placement deserve attention together.
Villa Regina at Boscoreale preserves a wine cellar with eighteen dolia in a complex whose original form dates to the first century BCE and which was buried by the eruption of AD 79.
A dolium is distinct from a transport amphora; its use must be established from context and residue rather than assumed from its shape.

Six dolia from the Garum Shop were examined; this is a specific archaeological context, not a claim that all dolia made fish sauce.
Jars, barrels, skins, leaves, pits and whole rooms decide much of what happens to fermented and cured food. This is how a container works on its contents, and how people in different places chose theirs.
Six ceramic dolia at Pompeii’s Garum Shop held fish-processing remains. They are vessels, distinct from masonry fish-salting vats; the evidence does not establish whether these specimens were portable or fixed in place.
A terzigno is a small wooden cask used in Cetara’s anchovy colatura tradition. A wooden follower and weights press its contents; the 2024 specification describes withdrawal through a hole in the cask’s bottom.
At North Abydos in Egypt, a fixed early Dynastic brewery comprised parallel semi-subterranean installations with rows of ceramic mash vats; excavation reports revise their number, scale and estimated batch capacity.
Ají amarillo is the orange-yellow Peruvian chilli cultivar group of Capsicum baccatum, used to colour and season huancaína sauce and ají de gallina. Published heat estimates do not establish one range for the named cultivar.
Toasted almonds are whole sweet almond kernels dry-roasted until golden to brown. Heat replaces their marzipan note with a roasted, nutty one; they thicken and flavour romesco.
Kodiak salmon, halibut and cod cut as seg'aq and hung on an initaq rack to become tamuuq, with kac'amaasaq and kupcuunaq named as different results.
Aniseed is the dried ripe fruit of Pimpinella anisum, an aromatic Apiaceae spice commonly called a seed. It adds a sweet, warm aroma to breads such as Moroccan krachel and South African mosbolletjies, and is distinct from star anise.
A fixed Late Chalcolithic installation in Areni-1 cave combined a shallow clay pressing basin with a large jar set into the cave floor and storage vessels nearby.
Ripe avocado flesh is the soft, buttery, fat-rich pulp of Persea americana, eaten raw. It is low in acid, so it is a fresh ingredient that needs care in chilled dishes.
A portable dome and pan used over a hearth, with embers on the lid and heat from below. Regional peka and saç forms share this principle while differing in materials, pan shape and how the food is cooked.

New technological contributions to Roman garum elaboration from chemical analysis of archaeological fish remains from the 'Garum Shop' at Pompeii (I.12.8)Fish remains were analysed from six dolia in Pompeii's Garum Shop and compared with a recipe by Gargilius Martialis; the evidence indicates different batches at the eruption.

The Roman city of Baelo Claudia and the secrets of garumCetariae were masonry fish-processing vats used with salting ponds; this is a different vessel type from ceramic dolia.
Production at Baelo Claudia is documented from the second century BCE to the fifth century CE.
