Blending Cider Apples for Balance and Flavour

Three families, three jobs

Cider apples are not dessert apples. Bite into a Kingston Black or a Tremlett's Bitter straight from the tree and you will pull a face: the fruit is dry, astringent, sometimes fiercely acidic, and rarely pleasant raw. That is the point. These apples carry the acid, sugar and tannin that yeast turns into something far better than the sum of its parts, and British growers have spent centuries sorting them into three practical groups.

Classification comes down to two measurements. Acidity is read as malic acid, usually between 2 and 12 grams per litre. Tannin is read as tannic acid equivalent, from nearly nothing in a dessert apple up to around 0.6 per cent in a heavyweight bittersweet. Sharps are high in acid and low in tannin; sweets are low in both but high in sugar; bittersweets are high in tannin, low in acid and generous with sugar. A fourth group, the bittersharps, combine high acid with high tannin and turn up in blends as intensifiers rather than foundations.

What each family contributes

• Sharps give lift, freshness and line. They sharpen the finish, keep a heavy cider from tasting syrupy and add a clean, bright note that survives months in bottle. Michelin and Bramley are dependable workhorses; Foxwhelp brings startling, almost grapefruit-like acidity and a touch of tannin.
• Sweets give sugar for fermentation and much of the aroma. Cox's Orange Pippin, Ashmead's Kernel and old cider sweets such as Sweet Coppin contribute perfume — honey, pear drop, rose — and soften the attack, though they leave little structure behind.
• Bittersweets give body, tannic grip and length. Dabinett is rich and spicy with a long, soft finish; Yarlington Mill is aromatic and lightly tannic, a useful bridge between families; Harry Master's Jersey is mild and mellow; Chisel Jersey is bold enough to carry a blend on its own.

A cider made only from bittersweets tastes broad and drying. Only sharps and it is thin and bracing. Only sweets and it is a soft, forgettable drink. Balance is not a compromise; it is the whole craft.

Working out a ratio

A sound starting point is 60 to 70 per cent bittersweet, 15 to 25 per cent sharp and 10 to 20 per cent sweet. Use it as a compass, not a rule. Aim for a combined gravity of around 1.050 to 1.060, acidity of 4 to 6 grams per litre of malic acid, and tannin somewhere between 0.15 and 0.30 per cent. Push acidity higher for a lean, aperitif style; push tannin higher for something to lay down for two or three years.

If your bittersweets are low in tannin — common in a wet year — a modest addition of a heavy variety such as Chisel Jersey, or a longer maceration, will do more good than any adjustment made later. If the juice tastes flabby at pressing, it will taste flabby after fermentation too. Fix it before the yeast gets to work.

Bench blending before you commit

The most useful habit in a cider shed is to taste blends in a glass long before they reach a barrel. Press each variety separately if you can, keep the juices in labelled containers and chill them overnight so they settle. Then make up small samples — 100ml in a clean glass is plenty — and build blends in 10 per cent steps: 70/20/10, 60/25/15, 65/20/15 and so on. Write down what you taste, not what you hope to taste.

Warm the samples to 15–18°C before judging them, because cold juice hides both aroma and tannin. Two approaches are worth knowing: a blend fermented together marries into a single character, while a blend assembled after fermentation keeps each variety distinct and lets you adjust right up to bottling. Many makers do both, fermenting a base blend and holding one or two components back as seasoning.

Planting and picking for a blend

If you are planting, think in ratios rather than rows. Roughly six bittersweets to two sharps and two sweets will give you a workable blend in most years, with a few extras for insurance. Most traditional cider varieties are self-sterile or triploid, so plant at least three that flower together — Dabinett, Yarlington Mill and Michelin overlap well in mid-season.

Ripening spreads the harvest from September to November. Early bittersweets such as Tremlett's Bitter come in first, maincrop Dabinett and Yarlington Mill follow in October, and many sharps hang late. Let the fruit sweat in shallow boxes for a week or two before milling; the flavour rounds out and the yield improves. A short maceration of six to twenty-four hours extracts colour and tannin, but leave high-acid fruit in contact with the pulp too long and you will pull out harshness that takes a year to soften.

Reading a blend that has gone wrong

• Thin and watery, no finish: not enough bittersweet. Add tannin-rich juice, or plan a longer maceration next season.
• Harsh, drying, metallic: too much sharp fruit, or tannin that is still young. Reduce the sharp proportion, or give it six to twelve months for the tannin to soften.
• Flabby and cloying: needs 10 to 15 per cent sharp fruit to restore the finish.
• Dull, with little aroma: the sweets are missing, or the ferment ran too warm. Ferment at 15–18°C and consider a perfumed sweet or bittersharp in the blend.

Keep a notebook. Record the varieties, the ratios, the gravity and the date, then taste the results at three months, six months and a year. No formula beats the record of your own orchard, and after a few seasons you will know exactly which tree to reach for when a blend needs lifting, filling out or reining in.
