Dark Mild to Dark mAIld

Early in 2025, I tried Timothy Taylor’s Dark Mild on cask. It was fantastic, I had to brew one once the weather got colder.

Interestingly enough, I believe Taylor’s Dark Mild is actually Golden Best with caramel put into the cask — it’s the same ABV (3.4%) too.

Upfront, this ended up as a double brewday.

The original recipe was an adaptation from David Heath’s Dark Mild.

Notes

Brew Day

This brew day started out great, I was well prepared and everything ran smoothly.

Grain

Mash

However, due to scaling the recipe down and having odd amounts of water, I ended up over sparging, diluting the wort substantially.

The fermentation went very smoothly, I didn’t cold crash in an effort to keep the beer as fresh/traditional as possible. However, I only hit an OG of 1.033, finishing at 1.010, resulting in a 3.2% beer. This wasn’t necessarily bad news, Timothy Taylor’s Dark Mild is 3.4% and very sessionable.

Fermentation

This was the first time I’d used S-04, it took a while to get going but then flew through the wort, minimal krausen.

Fermentation

Closed transfer.

Tasting

After conditioning and force carbing for a week, I pulled my first glass and my first impressions were great. The aroma was spot on, the taste, while being a bit thin as I’d anticipated, was solid too. My problem though, was head retention.

I tried a different tap and used a KegLand Stout Spout with creamer disks, but still the head would dissipate rapidly.

Batch1 - Pour

Enter Claude. After reviewing the grist and accounting for the over-sparge, it flagged the obvious thing I’d missed: no wheat, no oats, nothing to build a stable foam head. That night we rebuilt the recipe — the Dark mAIld.

Recipe 2

Grain

  • 2.75kg - Crisp Maris Otter (No.19 Floor Malted)
  • 200g - Crisp Torrified Wheat
  • 200g - Thomas Fawcett Flaked Oats
  • 200g - Thomas Fawcett Pale Crystal Malt
  • 100g - Weyermann Carafa Special II
  • 50g - Crisp Black Malt

Hops

  • 45g East Kent Goldings (EKG)

Hop Allocation

  • 25g - Boil (30min)
  • 20g - Boil (15min)

Water

Spotless / RO

  • 15L Mash
  • 10L Sparge

Water Treatment

  • 3g Calcium Chloride
  • 1.5g Gypsum
  • 1.5g Baking Soda
  • 1g Epsom Salt

Yeast

  • 1 pkg SafAle Fermentis S-04

Nutrients

  • 1 pkg ProMix - Boil (10min)

Hot Side

  • Mash: 69c for 60min
  • Mash Out: 75c for 10min

Cold Side

  • Primary: 7 days @ 18c
  • Diacetyl rest: 4 days @ 21c - 3 day ramp

Gravity

  • OG: 1.039-1.040
  • FG: 1.013-1.015
  • ABV: ~3.5%
  • IBU: ~20

Notes

To summarise the changes:

1) The recipe was scaled for ease of measurements - clean/rounded numbers.

2) I’ve moved from Tesco Ashbeck to Spotless Water. I had come across a thread on Reddit that Ashbeck had changed, and as I’ve never got round to replacing the RO system, I decided to give it a go. 46L for £2.35!

3) Mash ran at 69c rather than 67c

Grain Spotless

Brew Day

Another really smooth brew day. For next time, I will add a handful of rice hulls as the mash was a bit sticky and I had to turn the recirculation pump down. I also ran a new drill-powered mash stirrer for the first time. Immediate impact on efficiency — pre-boil reading hit 1.039 against an expected ~1.034 across five refractometer checks. I’m now consistently hitting 75–80%.

Mash

Fermentation

Exactly as before, bit of a slow start and then like a rocket.

Fermentation

Closed transfer as always.

Transfer

Tasting

What a difference. Miles better. Much more mouthfeel, aroma broadly similar. Both batches were single infusion — darker malts straight in, not added late. Worth noting for next time. The head retention, though: fantastic.

Batch2 - Pour 1 Batch2 - Pour 2 Batch2 - Minikeg

Closing notes

Unfortunately I don’t have the fermentation graphs for either brewday — the move to the new RAPT Brew app meant I lost the data older than 30 days. I’ll work out a nicer way to pull the data and keep it long term.

Cheers.
