Kleine Landlbirne

How it is classified

What it contributes to a blend

A direction, not a measurement. These bands are the level of resolution the evidence supports, and they say which way adding this fruit pushes a blend rather than what the finished cider will be.

Intensely pear-flavoured, and described by the Austrian ministry as carrying vanilla, light honey and a suggestion of banana.

Aroma

No aroma descriptors are recorded for Kleine Landlbirne, and for a great deal of cider fruit that is a finding rather than a gap. Bittersweet apples in particular contribute tannin, sugar and body while being close to aromatically mute, and most of what a cider made from them smells of was produced by the fermentation rather than carried in by the fruit. CiderHQ publishes the absence rather than filling the space with descriptors nothing supports.

Measured analysis

Each figure is shown with where and when it was taken. They are not averaged: the same cultivar grown in another climate genuinely gives different numbers, and collapsing them into one would be the most misleading thing this page could do.

Compare within a study to see where these figures sat among the other cultivars the same work analysed — which is a more robust statement than the figures themselves, because absolute values move between laboratories and the ordering inside one study mostly survives.

Watched in the orchard

What named research programmes recorded about this fruit at their own sites. Bloom, harvest and cropping belong to a place and a run of seasons rather than to a cultivar, so they are reported site by site rather than merged.

Not recorded. Austrian sources do not publish flowering groups or bands for Mostbirnen in any form CiderHQ has reached.

Juice and pressing

• 84 to 94 degrees Oechsle depending on rootstock — the highest in the trial
• 6.4 g/L malic and 7.1 g/L citric acid
• 2 450 mg/L total phenols
• 367 mg/L arbutin, the highest in the trial

How it is used

• A Mostviertel Most pear with an unusually specific described flavour.

About Kleine Landlbirne

Names, origin and identity

Cultivar naming is the hardest problem in cider fruit data. The same tree carries different names across ten miles, and two different trees have shared a name for two centuries.

Why it matters

• The highest sugar of any Austrian pear in the trial, and the only one on this site with an official flavour description naming vanilla and banana.

Fruit that plays a similar part

Cultivars sharing a classification under the same system and a comparable role in a blend. Not a similarity score — a stated relationship.

• Plant de Blanc

  The dominant poiré pear of the Domfrontais and the cultivar the Poiré Domfront appellation is built around.

• Green Longdon

  The senior member of the Longdon group, widely grown in north-west Gloucestershire and carrying six synonyms, three of which other Longdons also claim.

• Oldfield

  A Worcestershire perry pear with a nineteenth-century show reputation, giving a light, low-acid perry that has been made single-variety for well over a century.

• Speckbirne

  The principal Austrian Most pear, named in Austrian wine law for a lower acid floor, and the variety the Klosterneuburg trial pressed twice to two entirely different results.

• Taynton Squash

  A Gloucestershire pear named in seventeenth-century writing as one of the finest for perry, reduced to very few trees by the twentieth century and propagated back from them.

• Tumper

  A very early Three Counties perry pear whose juice contains almost no nitrogen a yeast can use, and more proline than any other variety measured.

What people ask next

Questions readers ask about the things this page mentions. Each one goes to the section that answers it rather than to a page written to receive the question.

• What is perry — Perry is an alcoholic drink made by fermenting the juice of pears, traditionally of specific perry pear cultivars rather than eating pears. It is to pears what cider is to apples, and has its own history in the three counties of England and in Normandy.
• How long can apples be kept before pressing
• What does sweating apples mean — Sweating is holding picked fruit in a heap or store for days or weeks before milling, so it softens, loses water and gains sugar concentration. Perry pears in particular are usually held until they yield to the thumb.
• What is juice blending
• What is the main austrian most pear — Speckbirne, which Austrian wine law names for a lower acid floor. It is also the clearest caution in the Austrian data: the Klosterneuburg trial pressed it twice and got two entirely different results.
• Is most made outside the mostviertel — Yes. Upper Austria carries the same pear and apple Most tradition as the Mostviertel next door, on a large orchard base, and the boundary between them is administrative rather than cultural.

  Fourteen Austrian perry pears trialled at the research station that also runs Austria’s statutory fruit-wine analysis panel. The only measured Austrian Mostbirnen data CiderHQ has found, and the first Austrian figures on the site. Its tables are scanned images with no text layer, so every figure published here was read from the rendered pages directly rather than from an extraction, and the source’s own typesetting error — Knollbirne’s residual sugar printed “3,o” — is recorded rather than normalised. The acid convention is tartaric rather than malic, which is Austrian wine law and is stated on every measurement taken from it.

  The Austrian agriculture ministry’s own account of its perry pears, in its register of traditional foods. It carries no analytical figures at all — no acid, no sugar, no tannin — and is cited here for synonymy, geography, dates and the ministry’s own descriptions of what the fruit tastes like. Its estimate of over 400 Mostbirne types in Austria is labelled by the ministry itself as an estimate, and CiderHQ repeats that hedge rather than the number alone.

  The instrument that decides what Most legally is in Austria, and the answer is: a fermented drink. That single fact is the one most often got wrong in English writing, because Most means the unfermented juice in Switzerland and is ambiguous in Germany. The ordinance also names two pear cultivars individually — Speckbirne and Schweizer Wasserbirne — in a derogation lowering their minimum acidity, which is a legislature encoding pomology. Retrieved from the federal cellar inspectorate’s mirror because the Austrian legal information system refused every automated request.
