Note on the Original Text
This recipe is written in an early 18th-century English hand, characterized by phonetic spelling (e.g., 'bery,' 'boyling,' 'dure your hand') and loose grammar. Directions unfold as a narrative sequence, without exact times or temperatures, assuming the cook's basic kitchen knowledge. Measurement units like 'quarts' and 'gallans' reflect period usage, which have been converted to liters here. Words like 'isinglass' are clarified for the modern reader (now often replaced by gelatin), and the concept of 'working' refers to fermentation. The overall tone assumes a hands-on, experiential approach rather than relying on strict recipes.

This recipe comes from Rachel Kirk, dated 1707, a time when home wine-making was a practical way to preserve the summer berry harvest for year-round enjoyment. Such recipes circulated among the gentry and aspiring middle classes eager to create domestic wines in the style of foreign imports. The detailed steps, including clarification with isinglass (a common fish-derived fining agent), suggest an understanding of both fermentation and sophisticated wine-making practices, signaling this was a recipe for those with time, space, and some resources.

Historically, the key tools would include large wooden or stoneware vessels for fermentation (with lids), a jelly bag (a fine cloth bag for straining juice), a wooden paddle or masher for bruising fruit, and a hearth or slow fire for gently dissolving isinglass (or gelatin). Glass bottles with corks would store the finished wine, and basic scales or measures allowed for proportioning sugar and fining agent.

Ingredients
- Ripe blackberries (amount as desired; e.g., 22 lbs for a large batch)
- Boiling water (enough to cover berries; e.g., 2–3 gallons per 22 lbs berries)
- Granulated sugar, 2.2 lbs per 2.6 gallons blackberry juice
- Isinglass, 4 oz (or powdered gelatin as modern substitute)
- Dry white wine, 1 pint (used to dissolve isinglass/gelatin)
- Additional blackberries (to provide 1 gallon of juice for clarification)
- Sugar cubes or lumps (one per bottle, optional)
Instructions
- Begin by selecting ripe blackberries.
- Place them in a large non-metallic vessel (preferably ceramic or glass) with a lid.
- Pour enough boiling water over the berries to just cover them.
- Allow to cool until the mixture is warm to the touch, then thoroughly mash or bruise the berries.
- Cover and leave the mixture at room temperature.
- After 3–4 days, when the berries have floated and fermentation is noticeable, strain off the juice into another clean vessel.
- For every 2.6 gallons of juice, add about 2.2 pounds of sugar and stir until dissolved.
- Allow this to ferment in a clean container for 7–10 days.
- After the initial fermentation, strain the liquid through a fine jelly bag or muslin into a large vessel.
- Soak 4 ounces of isinglass (or substitute with powdered gelatin if unavailable) in 1 pint of white wine for 12 hours, then gently heat until completely dissolved.
- Mix the dissolved isinglass into 1 gallon of blackberry juice, bring just to a boil, then combine this back into the main batch while still hot.
- This quantity will clarify up to 30 gallons of wine.
- Cover and let the vessel stand in a moderately warm place for 12 hours.
- After settling, siphon off the clear wine and bottle, adding a cube of sugar to each bottle if desired.
- If the vessel remains full and you're not ready to bottle, let it settle a bit longer before proceeding.

Cooking Estimates
Most of the time is spent waiting for fermentation and settling. Preparing the fruit and mixing takes about 1 hour. Cooking time is mainly for briefly heating the isinglass or gelatin mixture. Each serving of this wine contains about 100 calories. This recipe yields about 100 servings when using 10 kg of blackberries.
