What it does in your beer

Weyermann makes this malt for its very high enzyme power: it's a natural, highly effective supplier of amylolytic (starch-converting) enzymes. The flavour is malty-sweet with hints of honey, and the colour is very pale.

Weyermann lists it for whisky and other grain spirits and for special applications in breweries, bakeries and flour mills; its brewing specification names Pils, lager and specialty beers. In a brew it earns its place when the grist carries a large share of unmalted grain or flakes, which bring starch but no enzymes of their own.

At a glance

How much for a 20 L batch

Up to 60 % of the grist. On a typical 5 kg grist for 20 L that's up to 3 kg (30 × 100 g).

As a guide, 1 kg in 20 L adds ≈ 2.4 EBC of colour on its own and ≈ +10.5 gravity points (≈ +2.62 °P) at 75 % efficiency (approx., Morey colour / extract-based gravity, mid 3.2 EBC, 78 % extract).

Quantity = number of 100 g units: 30 = 3 kg.

How to use

• Mash it with the rest of the grist; its enzymes work on the starch of everything in the mash tun.
• Pair it with flakes or other unmalted grain, which bring starch but no enzymes.
• Weyermann's specification gives a saccharification time of max. 15 minutes (lab mash).

How much can I use?
Weyermann states up to 60 %. Its brewing specification lists Pils, lager and specialty beers.

Does it add colour?
Very little: 2.5–4.0 EBC. 1 kg in 20 L adds ≈ 2.4 EBC on its own (approx.).

Can you crush it?
Sure. Select Crushed in the Milling option; it is milled before dispatch and should be brewed within about 5 days.
