Two bottles labelled txakoli can answer to two different rulebooks. Bizkaia, Getaria and Álava each run their own denomination, and the only thing on the outside that says which one you are holding is the numbered back label.
How many txakoli denominations are there? Three separate ones: Txakolí de Bizkaia, Txakolí de Getaria and Txakolí de Álava. Txakoli is a traditional term protected under European rules, and each denomination has its own regulating council, its own rulebook and its own numbered back label.
Bizkaiko Txakolina is the denomination of origin for txakoli made in Bizkaia, recognised in 1994 and covering 36 wineries.
One protected word, three rulebooks
Txakoli-Txakolina is a traditional term protected under European rules, and three denominations of origin sit underneath it. They are not sub-zones of a single region: each has its own regulating council and its own rules on varieties, yields and qualification.
For a visitor that difference is practical rather than academic. A txakoli from Getaria and one from Bizkaia are made a province apart under separate regulations, and the label is what separates them. The denomination is printed on the label and on the back label, so the check takes a second in a shop.
Bizkaia’s version was recognised in 1994, after a group of producers grouped under the Bialtxa association in 1987 with backing from the Basque Government and the provincial council of Bizkaia.
The grapes allowed in the bottle
The rulebook splits varieties into three groups, which is why two txakolis from the same province can taste so different.
The main ones are Hondarrabi Zuri, the coastal white variety that sets txakoli apart from other wines according to the Consejo Regulador, and Hondarrabi Zuri Zerratia, a tighter-bunched grape giving floral and vegetal aromas with a slight bitterness. For reds and rosés the main grape is Hondarrabi Beltza.
Two reds are authorised without limits: Pinot Noir and Berdexarie, the local name for Cabernet Franc.
Six whites are authorised with limits: Mune Mahatsa (Folle Blanche), Izkiriota (Gros Manseng), Izkiriota Ttipia (Petit Manseng), Sauvignon Blanc, Riesling and Chardonnay. One blending rule is worth carrying: a rosé must be at least 50% red grape.
What the back label actually proves
Certification happens twice, and by two different bodies, which is the part almost nobody explains at the counter.
The sequence runs in three steps:
- The HAZI Foundation audits the winery — an external control body contracted by the regulating council runs checks, tests and administrative controls, then issues a certificate that the winery’s txakoli meets the denomination’s rulebook
- The council qualifies each batch — every lot destined for bottling goes through a chemical analysis and a tasting by five experts trained in sensory evaluation, so the check is repeated lot by lot rather than once a year
- The numbered back labels are released — only after that second step does the winery receive them, and they are numbered rather than generic
The legal frame is the Order of 17 June 2008, amended by the Order of 7 March 2012. The council itself combines members elected by growers and producers with representatives of the Basque Government and the provincial council of Bizkaia, and sits at Mendibile Jauregia in Leioa.
Thirty-six wineries across twenty-five towns
The regulating council’s directory lists 45 entries, and they are not all the same thing: 36 are wineries and 9 are grape growers who farm without bottling under their own name.
Those 36 wineries sit in 25 municipalities, from Karrantza in the far west to Markina-Xemein in the east and Orduña in the southern exclave. There is no single txakoli valley to drive through.
| Municipality | Registered wineries |
|---|---|
| Lezama | 5 wineries |
| Bakio | 3 wineries |
| Durango | 2 wineries |
| Ibarrangelua | 2 wineries |
| Orduña | 2 wineries |
| Zalla | 2 wineries |
| Muxika | 2 wineries |
| Another 18 municipalities | 1 winery each |
Lezama leads with five, more than Bakio, the coastal town whose name most visitors attach to txakoli and which has three. Lezama sits inland in the Txorierri valley, half an hour from Bilbao and with no sea view at all, and its neighbours Larrabetzu and Zamudio add one each.
The council names Uribe and Urdaibai as the districts with the most vineyard area and the most wineries. Urdaibai covers Ibarrangelua, Muxika, Busturia, Morga, Gernika and Arratzu, the same estuary reached by the Bilbao to Mundaka and Bermeo train, while Bakio sits on the road to Gaztelugatxe.
The vineyard, and why it is small
Txakoli vineyards are mid-slope plots, sheltered from northerly winds and angled for maximum sun, at an average altitude of 50 to 200 metres above sea level, according to the Consejo Regulador.
They are small and awkward to work with machinery, which is the reason txakoli production stayed local for so long and why bottles rarely travel far from the province. Vines are grown on trellises, with planting frames between 3 by 1.5 metres and 2.5 by 1.10 metres, and pruned cane-and-spur, leaving two long canes carrying six to eight buds each.
The climate is Atlantic, humid and mild, with rainfall between 1,000 and 1,300 millimetres a year, heaviest in winter, spring and part of autumn. Soils run to clay loam over limestone and marl.
The calendar has fixed markers: fruit set falls in the second or third week of June and véraison in the second or third week of August. March averages 11.1 degrees against February’s 9.9 over the last thirty years, and that jump is what triggers budburst.
Which txakoli to order
- After the classic → a white from Hondarrabi Zuri, fresh and slightly acidic
- Want more body → a berezia, aged on lees or fermented in barrel
- Curious about red → Hondarrabi Beltza, medium-bodied and lightly tannic
- Ordering rosé → at least half the blend is red grape by rule
- After bubbles → sparkling wines sit under an additional provision
- Unsure of a bottle → turn it round and read the numbered back label
Buying it in Bilbao
Txakoli is sold at the winery, in specialist shops and on market stalls, and the market route is the one that fits a visit rather than a car hire. None of the six municipal markets is more than a short walk or a metro ride from the centre.
La Ribera, in the old town, is the market most visitors reach, with its stall timetables in the guide to La Ribera market. The other five municipal markets keep their own hours, set out in the guide to Bilbao’s municipal markets, and in August most of them have no afternoon session at all.
Reaching the wineries themselves means leaving the city, since Lezama, Larrabetzu and Zamudio are Txorierri villages and Bakio is on the coast. Options without a car are covered in the guide to Bizkaia villages from Bilbao.
Frequently asked questions about txakoli
How many txakoli denominations are there?
Three separate ones: Txakolí de Bizkaia, Txakolí de Getaria and Txakolí de Álava. Txakoli is a traditional term protected under European rules, and each denomination runs its own regulating council, its own rulebook and its own back label.
What does the numbered back label on a txakoli prove?
That the batch passed the regulating council’s qualification procedure, which combines a chemical analysis with a tasting by five trained experts. Before that, the HAZI Foundation audits the winery and certifies it meets the denomination’s rulebook.
Which grapes go into txakoli from Bizkaia?
Hondarrabi Zuri and Hondarrabi Zuri Zerratia for whites, Hondarrabi Beltza for reds and rosés. Pinot Noir and Berdexarie are authorised without limits, and six more white varieties are authorised with limits, Chardonnay and Riesling among them.
Where are Bizkaia’s txakoli wineries?
Across 25 municipalities, not one wine region. Lezama has five of the 36 wineries, Bakio has three, and Durango, Ibarrangelua, Orduña, Zalla and Muxika have two each. The rest are single wineries scattered over the province.
Is txakoli always sparkling?
No. The classic style is a still white from Hondarrabi Zuri, fresh and slightly acidic. The denomination also covers rosé, red, barrel-fermented bereziak wines and sparkling wines listed under an additional provision of the rulebook.
A wine named after a word three provinces share is a wine you buy by reading the back of the bottle.
