Scottish Wee Heavy, Part Two: Clarify, Cold-Crash, and Bourbon-Oak Without a Barrel (2-Gallon)

Big malt. Clean finish. In Part Two of our 2-gallon Scottish Wee Heavy, we verify fermentation, rack off the yeast cake, and make the beer crystal-clear using gelatin finings plus a 48-hour cold crash. Then we “barrel-age” without a barrel: build a bourbon-oak tincture, strain it, and dose by the drop so you control flavor without risking oxidation or over-oaking the whole batch. Clear beer. Precise oak. Repeatable results.




Goal: take a high-gravity Scottish Wee Heavy from primary to bright, pour-ready beer and add precise “barrel-aged” character with an oak-bourbon tincture.

  • Batch size: 2 gal
  • OG: 1.114
  • FG (measured): ~1.030 (target 1.022–1.024)
  • ABV (approx.): 11.0% using (OG−FG)×131.25
  • Clarifier: Unflavored Knox gelatin
  • Cold crash: 24–48 hr at ~37–38°F (3°C)
  • Oak program: American oak chips → bourbon tincture, 1–2 weeks, then strain

Why stopping at ~1.030 is fine: A point or two high on a big beer is acceptable. Residual sweetness balances alcohol warmth in a Wee Heavy.


Step 1: Gravity Check, Taste, Decide

  1. Sanitize thief, hydrometer, and cylinder.
  2. Pull sample gently. Spin hydrometer. Read at the meniscus.
  3. If FG is stable and the sample tastes clean, proceed to secondary even if a few points high.

Future batches: For OG ≥1.060, pitch more cells (two dry packs or a starter).

Step 2: Clarify With Gelatin + Cold Crash

Ingredients (2 gal): ~½ cup very cold water, ~1 tsp unflavored gelatin.

Method

  1. Bloom: Sprinkle gelatin evenly over cold water. Rest 15–20 min until gelled.
  2. Dissolve: Microwave in 15-sec bursts, whisking between, until transparent. Do not boil.
  3. Dose: Pour clear gelatin into a sanitized secondary.
  4. Rack: Siphon beer gently on top. Avoid splashing.
  5. Cold crash: 24–48 hr at 37–38°F. Haze drops out fast.

Step 3: Oxygen Control That Matters

Keep transfers smooth. No splashing.

CO₂ blanket: If available, give the headspace a short CO₂ purge before installing the airlock. CO₂ is heavier than O₂. No CO₂? Use the smallest possible secondary to minimize headspace.

Step 4: Barrel-Aged Flavor Without a Barrel (Tincture)

Barrels are slow and risky. Chips dumped straight in can overshoot. A tincture gives precision and consistency.

You need

  • Clean mason jar with lid
  • Bourbon: 4–8 oz decent, everyday bottle
  • American oak chips: ½–1 oz

Make it

  1. Add bourbon and chips to the jar.
  2. Seal and store at room temp for 1–2 weeks, shaking daily.
  3. Strain through a coffee filter into a clean jar. Label and cap. Shelf-stable.

Why this wins

  • Dose to taste by the glass, bottle, or keg.
  • No risk of over-oaking the whole batch.
  • ABV impact is negligible at drop-level additions.

Step 5: Dose by the Drop (Simple Scaling)

Pour a 3 oz sample of the finished, carbonated beer.

Add 5–10 drops of tincture. Stir. Smell. Taste. Adjust.

Scale up using proportional math:

12 oz bottle = 4× your 3 oz drop count

16 oz pint = ~5.3×

2 gal keg (256 oz) factor = 256 ÷ 3 ≈ 85.3×

Example: 6 drops per 3 oz → ~512 drops for the full keg

Record the number. Repeat it for perfect reproducibility.

Troubleshooting

High FG/stall: Gently rouse yeast and raise temp a couple degrees. If needed, pitch rehydrated neutral yeast.

Gelatin clumps: Re-do bloom; use short heat bursts until clear.

Oxidation worry: Reduce headspace or purge. Keep transfers calm.

Over-oaked pour: Reduce drops next glass. Always titrate before dosing a whole keg.

Gear Checklist

Hydrometer + cylinder • Auto-siphon • No-rinse sanitizer • Secondary fermenter • CO₂ tank and line (optional but useful) • Thermometer • Pipette/eyedropper • Mason jars • American oak chips • Bottling or kegging setup

Tasting & Serving

Base Wee Heavy: big malt, caramel, warming finish, light residual sweetness.

Bourbon-oak variant: vanilla and toast from oak, bourbon aroma, rounder finish.

Serve: 6–10 oz in a snifter at 50–55°F.

Next Steps

Build a tincture library: oak, cacao nibs, cinnamon, citrus peel, peppers (use neutral vodka for non-oak infusions).

Re-brew with optimized pitch rate. Keep your dosing log. Establish your house profile.
