How it is classified

Long Ashton classification

Sharp

High acid, low tannin. Includes both purpose-grown sharps and many culinary apples.

Basis: Above about 0.45% w/v acid and below about 0.2% w/v tannin.

A sharp of high acid and negligible tannin, in line with culinary fruit generally.

Every classification on CiderHQ names its system. Why there is more than one.

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.

Contribution to a blend, scored 1–5 as a band. The filled segment is the typical value; the paler segments are the range.

Based on: its recorded classification

Description of an early culinary sharp. No cider analysis attaches to this cultivar. These bands were authored from description; published analyses of this fruit have since been transcribed onto the record from named trial programmes and are shown above. The bands are not derived from those figures, which is why this profile is marked as classified rather than measured.

Supplies sharp acid and low sugar early in the season, and nothing else.

Aroma

No aroma descriptors are recorded for Grenadier, 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.

Put Grenadier into a blend

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.

Measured on the fruit

Measured on the fruit itself, before anything was done to it. These figures hold whatever was later made from the juice.

How these were measured
  • Mean of the fruit sampled per accession; where a bracket is shown it is one standard deviation either side of the mean, not the observed range. Published to two decimal places and shown at the precision CiderHQ displays for the unit.
  • Mean of the fruit sampled per accession; where a bracket is shown it is one standard deviation either side of the mean, not the observed range.
  • Cornell generic starch–iodine chart, 1–8, where 1 is no hydrolysis and 8 is complete. Mean of replicate fruit; a bracket, where shown, is one standard deviation either side of it.
  • Penetrometer, mean of replicate fruit; a bracket, where shown, is one standard deviation either side of the mean.
  • Refractometer on pressed juice. Mean of replicates; a bracket, where shown, is one standard deviation either side of the mean.
  • Titration to pH 8.2 with sodium hydroxide, reported as malic acid equivalents. Mean of replicates; a bracket, where shown, is one standard deviation either side of the mean.
  • Meter on pressed juice before fermentation. Mean of replicates; a bracket, where shown, is one standard deviation either side of the mean.
  • Löwenthal permanganate titration, reported by the source as grams per litre of tannic acid equivalent and stored here as milligrams per litre by exact conversion so that it sits in one column with the Folin–Ciocalteu figures the site also holds. The two methods do not measure the same thing and are not interchangeable.
  • Enzymatic assay (Megazyme). Mean of replicates; a bracket, where shown, is one standard deviation either side of the mean.
  • D-sorbitol/xylitol assay kit (Megazyme), sorbitol dehydrogenase method. Mean of replicates; a bracket, where shown, is one standard deviation either side of the mean.
  • Published in the two-figure form the table uses (a printed 51 meaning 1.051) and written here in full.
  • Titration, reported as malic acid, on juice from freshly harvested fruit.
  • Method not stated in the compilation; the Long Ashton work behind it used Löwenthal permanganate titration.
  • A chart position, not a quantity. Almost every accession here scored at or near 8, which says the fruit was picked at or past full starch conversion rather than that the cultivars are alike.
  • One harvest at one site. Soluble solids move several degrees between seasons and with crop load.
  • A permanganate figure and a Folin–Ciocalteu figure for the same juice can differ by a factor of two. Compare this reading with other permanganate readings, not with a Folin one.
  • A National Association of Cider Makers compilation crediting three bodies of work — MAFF/ADAS acidity and pH from freshly harvested fruit, Long Ashton cider-making trials with dessert and culinary varieties reported in 1977, and the Long Ashton Annual Report for 1922. The compilation does not say which row came from which, so no row can be dated more precisely than the span of the three.

The compilation does not say which row came from which, so no row can be dated more precisely than the span of the three. Several cultivars appear more than once in this table under sample numbers, and the repeats are far apart: Bramley’s acid is 1.21, 1.05 and 1.43 per cent in three rows. Read any single row as one pressing of one parcel of fruit.

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.

USDA-PGRU Malus germplasm characterisation

USDA-ARS Plant Genetic Resources Unit, Geneva, New York, in the Finger Lakes region of western New York State · 2017 · Cornell University / USDA-ARS Plant Genetic Resources Unit

Humid continental, with cold winters and warm summers moderated by the Finger Lakes — a sharper seasonal swing than any of the European cider regions whose fruit the collection holds, and warm enough in late summer to bring acid down faster than a maritime autumn does.

Held as
PI 589684, held as “Grenadier”

One harvest season. Fruit assessed for weight, diameter, starch pattern index on the Cornell 1–8 chart and flesh firmness by penetrometer; juice pressed and measured for soluble solids by refractometer, titratable acidity by titration to pH 8.2 as malic acid, pH by meter, total phenolics by Löwenthal permanganate titration as tannic acid equivalent, and glucose, fructose, sucrose and sorbitol by enzymatic assay.

Typical English apple juice analyses

England — the compilation does not name the orchards · 1922–1977 · National Association of Cider Makers, Archive of Cider Pomology

English fruit-growing country, and no closer than that: the source gives neither site nor season for any individual row, which is a real limit on what the figures can be asked to do.

Listed as “Grenadier”

Juice from freshly harvested fruit. Acidity and pH credited to MAFF/ADAS; the remainder to Long Ashton cider-making trials with dessert and culinary varieties (1977) and to the Long Ashton Annual Report for 1922. Specific gravity is printed in a two-figure form and written out in full here.

How it is used

On its own

Not suited to a single-varietal cider

Very sharp and very low in sugar. Alone it would ferment to something thin and severe.

About Grenadier

Grenadier is an early cooking apple and, for a cidermaker, a source of August acid. Early juice is usually short of it — the early sweets and the early bittersweets both ferment to something flabby — and a proportion of Grenadier fixes the problem at exactly the point in the season when warm weather makes a high-pH ferment risky.

Its low sugar is a real limitation. It brings acid without alcohol, so a blend leaning on it will finish lower in strength as well as sharper, and that has to be planned for rather than discovered.

The tree is unusually healthy — resistant to scab and mildew, frost-tolerant, reliably heavy-cropping — which made it a standard choice for gardens and difficult sites long before anyone was pressing it.

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.

Origin · traditional account

Recorded from the 1860s and distributed by English nurseries thereafter. The raising is undocumented.
