Brewing a Scottish export ale at home

Export is the strongest of the everyday Scottish ales

Scottish ales were sold in strengths historically labelled by shilling price: light (60/-), heavy (70/-) and export (80/-). Export is the strongest of the three. Typical numbers: original gravity 1.040 to 1.060, final gravity 1.010 to 1.016, 3.9 to 6% ABV, 15 to 30 IBU and an amber to copper colour around 13 to 22 SRM.

The flavour is malt first: toffee, bread crust, a touch of dried fruit. Hops are there to balance, not to be tasted. Fermentation is clean, with few esters.

Skip the peated malt

Many homebrew recipes add peated malt to give a Scotch whisky note. The style guides treat peat smoke as a fault. Peated distilling malt is intensely phenolic and even 2% can make the beer taste of TCP. If you want smoke, brew a smoked porter instead.

A grist built on pale ale malt

For 20 litres at about 1.052:

• 4.2 kg Maris Otter or another British pale ale malt (88%)
• 0.3 kg medium crystal malt, around 120 EBC (6%)
• 0.2 kg Munich malt (4%)
• 0.08 kg roasted barley (2%)
• Mash at 67 to 68 °C for 60 minutes for a fuller body

The roasted barley is there for colour and a dry edge, not roast flavour. Keep it at 2% or below. About 35 g of a 5% alpha English hop such as Fuggle or Goldings at 60 minutes gives roughly 20 IBU.

Boil down the first runnings for depth

This is the trick that makes the beer. Take the first 2 litres of wort off the mash into a separate pan and boil it hard until it reduces to about 0.5 litres, thick and dark amber. Add it back into the main kettle. The reduction builds caramel and toffee flavours that crystal malt alone gives in a flatter way.

Watch the pan. Thick wort scorches quickly on a gas burner. A burnt reduction ruins the batch. Stir it and lower the flame as it thickens.

A cool, clean fermentation

Scottish ale strains ferment well cool. Pitch at 15 to 16 °C and hold there for the first five days, then let it rise to 18 °C to finish. Warmer fermentation adds fruitiness that competes with the malt. In most Indian cities that means a fridge with a controller or a water bath. Our guide to amber ale with crystal malt covers the same colour range with a hoppier balance.

Expect final gravity around 1.012 to 1.014. Cold condition for a week if you can, then carbonate lightly to about 2.0 to 2.3 volumes. Serve at 10 to 12 °C, not ice cold, so the malt shows.

What a judge would look for

A good export is clean and malty with a dry enough finish that a second pint appeals. The common faults are cloying sweetness from too much crystal, diacetyl from a rushed fermentation and smoke from peated malt. Being able to tell a rich malt character from a sweet, underattenuated one is a palate skill worth training.

Water and finish set the balance

Malt-led beers like a little chloride. If your water is soft, add about 3 g of calcium chloride and 1 g of gypsum to the 20 litres. That gives calcium for yeast health and a fuller palate without making the hops taste sharp. If your borewell water is hard, cut it with RO first. The darker malts in this grist tolerate some carbonate, but the crystal and the reduction already push sweetness, so you do not want a high mash pH making it flabby.

Aim for mash pH around 5.3 to 5.4. Check the final balance by tasting a warm, flat sample from the fermenter when gravity settles. It should finish dry enough that the toffee note fades within a few seconds. If it lingers like a sweet, consider a lower mash temperature or less crystal next time.

Scottish ales also take well to a cask or a lightly carbonated keg. Low carbonation and a cellar temperature serve let the malt speak.

One reduction teaches more than a recipe

Next time you brew any amber beer, pull 2 litres of first runnings into a separate pan and reduce it to a quarter. Taste a spoonful of the cooled reduction against the main wort. That one comparison shows you what the trick adds before you commit a whole batch to the style.

Common questions

Should Scottish export ale taste smoky?

No. Peat smoke is considered a fault in the style. Depth should come from malt and caramelised wort.

What does 80 shilling mean?

It is a historical label for strength and price. 80/- was export, stronger than 60/- light and 70/- heavy.

What temperature should I ferment Scottish ale at?

Around 15 to 16 °C for the first days, rising to about 18 °C to finish, for a clean malt-led beer.
