Ruby Mild Beer Recipe: How to Brew a Ruby Mild Beer

Ruby Mild Beer is not a complicated beer to brew, but it rewards attention to detail. Pale Malt forms the base of the mash here, and Golding 5.5% carries the hop character through to the glass.

Brew Day, Step by Step

1

Mash · ~60 min

Mash the grain bill, led by Pale Malt, at a steady temperature to build the fermentable sugars this style needs. Sparge slowly so you do not lose efficiency.

2

Boil · ~60-90 min

Bring the wort to a boil and work through the hop schedule, starting with Golding 5.5%. This is also where you will add any fining agent for a clearer finished beer.

3

Ferment · 22C (72F)

Pitch Wyeast 1187 Ringwood Ale once the wort has cooled to fermentation temperature and hold it steady. Primary fermentation is the most active week, do not rush it.

4

Condition · 3 weeks at 12C (54F)

Rack to secondary (or leave in primary if your recipe calls for it) and let the beer round out at a cool, steady temperature. This step does more for the final flavor than people expect.

5

Package · 1 day, then wait

Bottle or keg once gravity has held steady for a few days in a row. Give it time to carbonate and, for bigger styles, additional time to mellow before your first taste.

That’s the shape of brew day and the weeks after it. For the exact grain bill, hop schedule, and full step-by-step instructions with amounts, use the recipe card below.

Common Questions

Can I scale this recipe up or down?
Yes, the grain bill and hop schedule scale linearly with batch size. Just make sure your equipment, mash tun and boil kettle both, can actually handle the volume you are scaling to.

What is the biggest mistake homebrewers make with this style?
Rushing the schedule. Pulling a beer off yeast too early or skipping conditioning time is the most common way to shortchange a recipe like this one.

Can I substitute a different yeast strain?
You can, but expect the flavor profile to shift. Stick close to the same yeast family (English ale, American ale, Belgian, lager, etc.) if you want a result close to what this recipe is aiming for.
