López de Heredia: even the barrel is made in-house

20 October 2026 · Vikipedia

Curiosity · Winery. A conversation about Viña Tondonia easily turns to time. Years in barrel, years in bottle, years spent trying to remember where the corkscrew went. Yet López de Heredia has another story worth following: the container itself.

The Haro winery maintains its own cooperage workshop. Its documentation describes direct involvement from selecting timber to building barrels. Long before the wine arrives, somebody has already made quite a few decisions.

A barrel begins before it looks like a barrel

The long pieces of wood forming its walls are called staves. Cutting them, putting them together and hoping the wine will cooperate is not quite enough. Preparing the timber is part of the job.

López de Heredia distinguishes drying from seasoning: reducing moisture is not the whole story. Changes also take place in the wood’s components. Its account describes outdoor preparation before the workshop stage. The barrel starts taking shape, in that broader sense, while it still looks like a stack of planks.

Toasting is not an intensity contest

Heat helps bend the staves and transforms components of the wood. The winery explains its preference for a medium toast, consistent with the style it wants to make. This is a choice made by this producer, not a rule turning every other toast level into a mistake.

Be wary of the shortcut “more toast means better wine”. A technical decision matters for what it contributes to the whole, not for how impressive it sounds on a tour. Wine does not automatically improve by becoming more like breakfast.

What this tells us about Tondonia

It invites us to look beyond the number of months spent ageing. Oak origin and preparation, stave cutting and toasting are separate decisions. Compressing them all into the word “barrel” leaves quite a lot out.

It also helps explain why keeping a craft within a winery can be part of its working approach: it allows direct involvement in the vessel. This does not prove that making barrels in-house is superior to buying from a good cooper. There is more than one route to a suitable barrel.

A short guide to observing the craft

Three questions help organise the process. First, which wood is selected? Next, how is it prepared before construction? Finally, how is it shaped and what toast is intended? These are connected decisions, but knowing one does not automatically reveal all the others.

“Oak” identifies a material, “medium toast” a workshop decision and “six years in barrel” an ageing duration. Compressing everything into “tastes woody” loses the process we wanted to understand. A cellar visit improves when we ask about a particular operation instead of expecting an adjective to do the cooper’s job.

Return to a bottle with its own facts

The Tondonia Reserva 2008 entry records its grape blend and barrel-ageing period as documented by the producer. Here we examine the craft of building the vessel. Reading both separates a house practice from the details of one vintage.

Return to the Rioja guide to locate Haro too. Where grapes grow and what happens afterwards are separate questions. Connecting them tells us more than attributing every impression of tobacco or spice to an operation we have not witnessed.

A useful question for the next glass

Alongside “how long was it aged in wood?”, try “which wood, and with what intention?”. The answer may tell you more than a number on its own.

An important distinction: this article describes the producer’s documented practices. It does not identify the exact barrel used for a particular bottle of Tondonia Reserva 2008, or attribute a tasting sensation to an individual stave. We would need information we do not have. The craft is interesting enough without giving it psychic powers.
