Scottish-style ales are among the most misunderstood beer styles in homebrewing, commonly described as “smoky” (they’re not, traditionally) or assumed to be sweet (only if fermented too warm or underpitched). What a well-brewed Scottish ale actually is: a deeply malt-forward, clean, low-bitterness beer with remarkable complexity from caramel and toffee malt character, a slightly lower carbonation than English ales, and a dry finish that keeps the sweetness in check. I’ve brewed many Scottish ales over the years and the key to getting the style right is understanding what it actually is, not what the “Scottish = smoke and peat” stereotype suggests.
Style overview: Shilling designations
Scottish ales are traditionally categorized by shilling designations (60/-, 70/-, 80/-) that originally referred to the price per hogshead of beer in 19th-century Scotland, higher shillings meant stronger, more expensive beer. In modern homebrewing terms:
- 60/- (Light): OG 1.030–1.035, ABV ~2.5–3.2%. Very light-bodied session ale. Largely historical today.
- 70/- (Heavy): OG 1.035–1.040, ABV ~3.2–3.9%. The everyday Scottish pub ale. Restrained hop bitterness, clean malt character.
- 80/- (Export): OG 1.040–1.054, ABV ~3.9–5%. The most commonly brewed Scottish ale style today. Rich malt character, caramel notes, very low bitterness (15–30 IBU).
- Scotch Ale / Wee Heavy: OG 1.070–1.130, ABV ~6.5–10%. Strong, rich, intensely malty, sometimes with a hint of smoke. This is the style most commonly associated with export “Scottish ale” internationally.
80/- recipe (5 gallons, all-grain)
- Grain bill: 9 lbs (4.1 kg) Maris Otter pale malt; 8 oz (225g) Crystal 80L; 4 oz (113g) Crystal 120L; 4 oz (113g) Roasted Barley (for color depth, not roast flavor, small addition). Target OG: 1.048.
- Mash: Single infusion at 156°F/69°C for 60 minutes. The slightly elevated temperature creates a fuller body and residual sweetness appropriate to the style.
- Hops: East Kent Goldings, 1.5 oz at 60 minutes for 20–25 IBU. No late hop additions, Scottish ales are not hop-forward.
- Yeast: Wyeast 1728 (Scottish Ale), WLP028 (Edinburgh Ale), or Mangrove Jack’s M15 (Empire Ale). Ferment cool, 60–62°F/15–17°C. Scottish ale character comes partly from cool fermentation that suppresses ester production.
- Fermentation: 14 days primary at 60–62°F. No diacetyl rest needed if fermented cool throughout, low fermentation temperature prevents diacetyl formation in most cases.
The “smoke” question
Many homebrew recipes for Scottish ale include small amounts of peated malt to add a smoke character associated with Scotch whisky. This is historically debatable, traditional Scottish ales were not peated, and the association with smoke comes from conflating Scottish beer with Scottish whisky culture. Modern BJCP guidelines for Scottish Ale explicitly note that smoke is not a characteristic of the style. If you want to brew a smoked Scottish ale as a creative variation, a small peated malt addition (2–4% of grain bill) can be interesting, but it’s not traditional. Brew the style first without smoke, the malt complexity from crystal malts and a careful mash is more than sufficient for a compelling beer.
Common Questions
What’s the difference between a Scottish Ale and a Wee Heavy?
A Wee Heavy (Scotch Ale) is essentially an extreme version of the Scottish Ale concept, the same malt-forward, low-hop profile but amplified to strong ale strength (6.5–10% ABV) with intensified caramel, toffee, and sometimes dried fruit character. Where an 80/- is a sessionable (by British standards) pub ale at 3.5–5%, a Wee Heavy is a warming sipping beer. The production technique differs too: Wee Heavy benefits from a first-wort caramelization technique where the first runnings from the mash are kettle-caramelized before adding the remaining wort, creating deep toffee and caramel compounds not achievable through malt alone. This caramelization technique, along with a rich crystal malt bill and high-gravity fermentation, is what gives an authentic Wee Heavy its distinctive character.
