Torrified wheat in English ales

What torrified wheat is

Torrified wheat is whole wheat grain heated rapidly to a high temperature until it puffs up, much like popcorn or puffed rice. The heat gelatinises the starch inside, so the grain can go straight into the mash without a cereal cooker.

It is not malted. There is no germination, so there are no enzymes. The grain has no husk either, because wheat sheds its husk at threshing. In the mash, torrified wheat relies on the base malt to convert its starch, just like flaked grains.

Why English brewers add it

The main reason is foam. Wheat is rich in proteins and glycoproteins that help bubbles hold together. A small share of torrified wheat helps a bitter or mild build a tight, lasting head and leave lacing down the glass. That matters for cask ale, which is served with low carbonation and needs every bit of foam help it can get.

Torrified wheat also adds a little body and a clean, slightly nutty, grainy flavour. It is cheap compared with wheat malt and blends quietly into the background of a malty English beer. Our guide to wheat malt in brewing covers its malted cousin.

How much to use

Typical rates in English ales are modest:

• Bitter and best bitter: 5 to 10% of the grist.
• Mild: 5 to 10%, where it helps a low strength beer feel fuller.
• Pale ale and ESB: 5 to 8%.
• Golden ale: up to 10% for a pale, foamy beer.

Going much above 10% rarely adds more foam but can cloud the beer and slow the runoff. The point is a supporting role.

Milling and mashing it

Torrified wheat is light and puffy, so it behaves strangely in a mill. It can bounce through a roller mill set for barley without being cracked. Many brewers run it through with the malt so the denser grain helps crush it, or set the mill a little tighter for the wheat. Uncracked kernels give up little extract.

Mash it with the rest of the grist at a normal single infusion temperature, around 65 to 67 °C for an English ale. At 5 to 10% of the grist, the husk from the pale malt is enough to keep the grain bed open.

The one floor detail worth knowing: torrified wheat is dusty. Wear a dust mask when milling, keep the mill room clean and do not let the dust settle near open fermenters.

Keeping a head in a warm taproom

In India, most English-style bitters are served from kegs rather than casks, often in warm taprooms where a beer sits on the table for a while. Higher carbonation gives keg beer more foam to start with, but heat, oily food and glasses with detergent residue all knock it down quickly.

Torrified wheat cannot fix a dirty glass, but it gives the beer a better chance. A head that holds for a few minutes makes a bitter look and smell the way it should, because foam carries aroma to the nose. Pair the wheat with rinsed, properly washed glassware and a pour that builds a two-finger head. The beer will then look as good at the end of the glass as at the start.

A worked bitter for 20 litres

Here is a simple English bitter to try torrified wheat in context, aiming for about 1.040 original gravity, 30 IBU and around 4% ABV:

• 3.2 kg pale ale malt (87%)
• 0.3 kg torrified wheat (8%)
• 0.2 kg crystal malt around 120 EBC (5%)
• English hops such as Fuggle or East Kent Goldings to about 30 IBU
• An English ale yeast fermented at 18 to 19 °C

Mash at 66 to 67 °C for an hour. Serve with gentle carbonation to see what the wheat does for the head. Our guide to Fuggles and East Kent Goldings in English ales covers the hop side.

Finding it and what to use instead

Torrified wheat is a British maltster's product and can be hard to find in India. Importers of English malts may stock it alongside pale ale malts and crystal malts. If you cannot get it, there are reasonable substitutes:

• Flaked wheat: also pre-gelatinised and enzyme free. It behaves very similarly at the same rate.
• Wheat malt: gives foam and body with a slightly bready flavour and its own enzymes.
• Puffed wheat breakfast cereal: only if it is plain, with no sugar, salt or flavour. Check the pack carefully.

Store any of these sealed and dry. In humid weather, puffed grain softens and goes stale quickly.

Foam is a recipe decision

A good head is built from many small choices: grain, hop, yeast, carbonation and how clean the glass is. Torrified wheat is one of the cheapest and easiest of those choices. Understanding the proteins behind foam and what kills it is part of the deeper science of beer quality.

Your first step: brew your next bitter twice, once with 8% torrified or flaked wheat and once without. Compare how long the head lasts in identical clean glasses.

Common questions

What does torrified wheat do in beer?

It mainly improves foam and head retention, thanks to wheat proteins. It also adds a little body and a clean, nutty grain flavour.

How much torrified wheat goes in a bitter?

Usually 5 to 10% of the grist. More rarely adds extra foam and can slow the runoff.

What can I use instead of torrified wheat?

Flaked wheat is the closest substitute at the same rate. Wheat malt also works but adds a bready note and its own enzymes.
