Chateau Saint-sulpice Merlot Blend Recipe

1. Taste & Plan

Chill and decant small samples (1–2 oz) of each component wine so they are all at similar serving temperature. Taste each separately and note characteristics: Merlot base should provide plush fruit and mid-palate, Cabernet Sauvignon adds structure and black-fruit, Malbec lends color and spice, Petit Verdot adds tannin and floral lift. Decide on blending order and keep target blend ratio roughly Merlot 60%, Cabernet 20%, Malbec 10%, Petit Verdot 5%, reserve Merlot 5% (adjust to taste).

2. Combine the measured components in a clean, sanitized glass or stainless steel jug: 3 cups Merlot base, 1 cup Cabernet Sauvignon, 0.5 cup Malbec, 0.25 cup Petit Verdot, and 0.5 cup reserve Merlot. Stir gently with a sanitized stainless spoon for 30–60 seconds to integrate. Avoid vigorous agitation that can introduce oxygen.

3. Taste the combined blend. Evaluate color, aroma, mid-palate, finish, acidity, and tannin. If the blend feels short on mid-palate or fruit, add small increments (1–2 tbsp) of reserve Merlot and re-taste. If it needs more structure, add up to 1–2 tbsp Cabernet. Make adjustments in small increments to preserve balance.

4. If you desire a subtle oak signature, add 2 tbs of pre-soaked medium-toast oak chips in a sanitized tea infuser or mesh bag. Let the chips steep in the blended wine for 1–3 days, tasting daily. Remove when desired oak level is reached. Do not let chips contact the wine for longer than necessary to avoid overpowering.

5. If the blend lacks a touch of structure, dissolve 1 tsp wine tannin powder in a little wine and stir into the blend. Mix thoroughly and wait 24 hours, then re-taste for astringency and balance.

6. If slight microbial protection is needed, add approximately 1 tsp of a prepared potassium metabisulfite solution (calculate to achieve roughly 50 ppm free SO2 based on batch size). Mix gently and allow to rest 24–48 hours. (Note: exact sulfite dosing should be calculated from lab measurements; this is a guideline.)

7. If sweetness or finishing balance is required after cold stabilization or tasting, dissolve up to 1 tsp grape sugar in a small amount of warm water, cool, and stir into the blend. Make additions in very small increments and re-taste until desired balance is reached.

8. Polish the wine by passing it through a sterile filter or using filter pads to remove fine particulates, if available. This step improves clarity and shelf stability prior to bottling.

9. Sanitize bottles, corks, and bottling equipment thoroughly. Rack the blended wine off any sediment into a sanitized bottling bucket, leaving behind lees and any oak chips or solids.

10. Using a bottling siphon and filler, fill each 750 ml bottle to approximately 1–1.5 cm headspace below the cork line. Avoid splashing to minimize oxygen pickup.

11. Insert natural corks using a corker. Wipe bottles clean and label them with the name 'Chateau Saint-Sulpice Merlot Blend', blend date, and any other notes. Allow bottles to rest upright for 24 hours to settle corks, then store horizontally in a cool, dark place (50–60°F / 10–15°C) for at least 3–6 months to allow the blend to integrate. Taste periodically and adjust cellaring time based on development.
