How to Make Blackberry Wine (1 UK Gallon Recipe)

 blackberry

Blackberry wine is one of the most iconic hedgerow wines in the UK. Rich, deeply coloured, and packed with wild fruit character, it produces a full-bodied red-style wine that often improves dramatically with age.

Wild blackberries (brambles) are ideal, especially those picked in late summer or early autumn. After a frost or a spell of cool nights, the flavour deepens and the natural sugars increase slightly. This wine is often described as having a “jammy” character when young, which gradually softens into a smooth, rounded, almost wine-shop-quality red after maturation.

Wine Profile

  • Style: Country Red Fruit Wine

  • Colour: Deep ruby to dark purple

  • Body: Medium to full

  • Sweetness: Dry (can be back-sweetened)

  • Acidity: Medium

  • Alcohol: 11.5–13% ABV

  • Yield: Approximately 1 UK gallon (4.5 L), around 6 × 750 ml bottles

  • Difficulty: Beginner to Intermediate

Harvest Calendar

  • Harvest Season: August – October (UK)

  • Best Picking Time: Fully black, slightly soft berries after warm days and cool nights

  • Suitable for Freezing: Yes (highly recommended)

  • Best Source: Hedgerows, woodland edges, gardens

Ingredients

  • 4.5–5.5 lb (2.0–2.5 kg) fresh or frozen blackberries

  • 2.25–2.75 lb (1.0–1.25 kg) white sugar

  • Water (to make up to 1 UK gallon / 4.5 L total volume)

  • 1 tsp yeast nutrient

  • ½ tsp pectic enzyme

  • 1 Campden tablet (optional, recommended for fresh-picked fruit)

  • Wine yeast (half packet recommended):

    • Lalvin 71B (recommended for fruity, rounded style)

    • Lalvin D47 (more structured, fuller body)

    • EC-1118 (very dry, clean fermentation)

Optional Ingredients

  • ½ tsp wine tannin (recommended for structure)

  • Juice of ½ lemon (if berries are low acid or very sweet)

  • 1 cinnamon stick (light spice note)

  • 1 tsp glycerine after fermentation (for mouthfeel)

Preparation

  1. Wash berries lightly and remove any leaves, stems, or unripe fruit.

  2. If using fresh hedgerow berries, check carefully for insects or debris.

  3. Freeze the berries overnight if possible — this improves juice extraction significantly.

  4. Lightly crush the fruit using a potato masher or sanitised hands.

  5. Place crushed berries into a sanitised fermentation bag inside the primary fermenter.

Making the Must

  1. Dissolve the sugar in approximately 2.5 litres of boiling water.

  2. Pour the hot sugar solution over the fruit.

  3. Add cool water to reach 1 UK gallon (4.5 L total volume).

  4. Allow to cool below 25°C (77°F).

  5. Add:

    • Pectic enzyme

    • Yeast nutrient

    • Crushed Campden tablet (if used)

  6. Cover and leave for 24 hours if Campden was added.

Primary Fermentation

  1. Add yeast and stir well to distribute evenly.

  2. Stir once or twice daily to break up the fruit cap.

  3. Push the fruit bag under the liquid each day.

  4. Ferment for 5–7 days at 18–22°C.

Transfer to Secondary

  1. Lift the fruit bag and allow it to drain naturally — do not squeeze hard.

  2. Siphon liquid into a sterilised demijohn.

  3. Fit airlock.

  4. Top up with cooled boiled water if required.

Secondary Fermentation

Allow fermentation to complete over 4–6 weeks.

Rack off sediment when 1–2 cm of lees forms at the bottom.

Clearing & Aging

Once fermentation has finished:

  • Allow to clear for 2–3 months

  • Rack once or twice if needed

  • Bottle once bright and stable

Blackberry wine improves significantly with time and should be aged for at least 6–9 months, with 12–18 months giving a much smoother, richer result.

Expected Results

  • Original Gravity: 1.090–1.098

  • Final Gravity: 0.995–1.000

  • Alcohol: 11.5–13% ABV

Tips for Better Blackberry Wine

  • Frozen berries give better extraction and colour than fresh-picked alone.

  • A mix of ripe and slightly overripe berries produces deeper flavour.

  • Avoid squeezing the fruit bag — it can release harsh tannins.

  • 71B produces a softer, fruit-forward wine; EC-1118 gives a drier, more “wine-like” finish.

  • Blackberry wine often tastes sharp when young but improves dramatically with aging.

About Blackberry Wine

Blackberries (brambles) are one of the most abundant wild fruits in the UK and have been used for centuries in rural winemaking. Traditionally foraged from hedgerows in late summer, they were often combined with apples or other hedgerow fruits when harvests were abundant.

Blackberry wine is known for its deep colour and robust flavour. While it can taste slightly tart and jam-like when young, it matures into a smooth, rich wine that rivals some light red grape wines in complexity.

Serving Suggestions

  • Serve slightly cool (12–14°C)

  • Pairs well with roast meats, game, and hard cheeses

  • Excellent with chocolate-based desserts when slightly sweetened

  • Can be enjoyed as a winter warming wine when aged

Storage & Aging

  • Improves for up to 2–3 years

  • Store in a cool, dark place

  • Best drinking window: 9 months – 2 years

  • Benefits greatly from bottle aging

Frequently Asked Questions

Can I use frozen blackberries?
Yes — and they often produce better results than fresh.

Why is my blackberry wine cloudy?
Pectin haze is common; ensure pectic enzyme is used and allow more time.

Can I make it sweeter?
Yes, but only after stabilising the wine.

Do I need to remove seeds?
No — they add structure and are strained out during fermentation.

Can I mix blackberries with other fruit?
Yes — apple, elderberry, and raspberry all work well
