‘Base malts’ are the malt or malts in a grist which, when mashed, provide the bulk of the fermentable sugars in a wort. After being malted, base malts are very lightly kilned both to dry the malt and to develop subtle flavors.
Because of their high fermentable sugar potential, and because of their starch converting enzymes, these light colored (low Lovibond/SRM) malts are the primary malts used in most beers made “from scratch” by advanced brewers or commercial breweries. Due to the fact that the base malt accounts for the majority of the grist in most beers, the subtle differences between them can make a significant difference in the final beer. Country of origin is an important aspect in identifying those subtle differences which result in very different beers.
Extract brewers can use them to color and flavor light beers, adding interest to their brews in much the same way that more colorful and assertive specialty malts would be used with other beer styles.
A two row pilsner malt from Belgium which makes a fantastic base malt for Trappist and Farmhouse style ales. Light color is complimented by a delicate biscuity flavor and aroma.
Appearance
Color: 1.5° Lovibond - Contributes light straw color
A German, lager-style base malt produced from high-quality, 2-row spring barley. It contributes a pale-straw color to wort and adds mild, malty-sweet flavor with gentle notes of honey. This malt also provides the finished beer with substantial body and mouthfeel, as well as good foam development and head retention.
Appearance
Color: 1.5 - 2.2° Lovibond - Contributes light straw color
A light-colored base malt made from a blend of American 2-Row barley varieties. It is darker than most lager malts, but lighter than most pale ale malts. It has moderate protein levels, and good extract yield. Its neutral characteristics make it extremely versatile, and it is widely used by American craft breweries as their standard base malt for any beer style.
Appearance
Color: 1.7 - 2.2° Lovibond - Produces a straw color when used alone
High Color 2 Row, often referred to as "Pale Malt", contributes a light golden color and a bold, rich, malty character with biscuit notes making a solid malt backbone for bigger beers.
Appearance
Color: 2.6 - 3.0° Lovibond - Contributes a golden color
A medium color pale malt with exceptionally high alpha amylase and diastatic power with the ability to help convert starches present in adjuncts which lack the ability to self-convert. Six Row Malt has a higher percentage of husk, which makes it useful when brewing beers that employ grains such as wheat, which have no husk of their own.
Appearance
Color: 2.1 - 2.5° Lovibond - Contributes a golden color
Good for Starch Conversion?
Yes, 6-Row contains an exceptionally high level of enzymes.
A UK base malt which gives a beautiful mouthfeel to bring balance to beers with even the gutsiest hops. And when you drop the gravity for a session beer, you won't lose out on body. This gives the biggest base of any malt without adding color, resulting in exceptional beers.
Appearance
Color: 2.1 - 2.8° Lovibond - Contributes a golden color
A favorite of many brewers for its earthy, nutty malt character. Maris Otter Pale Malt is a British, high-color "pale malt" made for ales from the famous Maris Otter barley variety. It is renowned for its ability to enhance foam formation and palate fullness and for producing a consistent, flavorful base malt. The low protein content and high degree of modification make for easy mashing and lautering.
Appearance

Good for Starch Conversion?
Yes
Non-Barley Malts
Lacking in husk material, some non-barley malts, such as wheat and rye, may present unique sparging problems if used alone in amounts larger than one pound. Mash them with enough extra mash water to keep them from sticking together, or mash them together with at least 30% malted barley and perhaps some extra rice hulls, oat malt, or 6 Row Malt to help with separation.
Low color oat malt is gluten-free and adds a nutty oat flavor and creamy mouthfeel. Functionally works similar to rice hulls as an aid in increasing sparge efficiency.
Appearance
Color: 1.9 - 2.3° Lovibond - Contributes a golden color
Good for Starch Conversion?
No, it may not contain enough enzymes to self-convert.
Rye malt lends a slightly spicy flavor profile and high protein content. Recommended for 10 – 20% inclusion in mash. It is higher in protein and beta-glucans, so rice hulls are recommend to avoid stuck mashes.
Appearance
Color: 1.8 - 3.0° Lovibond - Contributes a golden color
Good for Starch Conversion?
Yes, but due to lack of husk it should not be used for more than 30% of the malt base or it may result in a stuck mash.
Toasted, Light Roasted & Kilned Malts
‘Kilned’ malts have undergone further kilning relative to base malts. The extended kilning imparts more complex aromas and flavors, with different kilning procedures accounting for the different malt varieties.
‘Roasted’ malts have been heated at high temperatures in drum roasters for various lengths of time.
The high temperatures can denature enzymes, therefore many high-kilned & roasted malts do not retain the ability to self-convert.
Vienna malt is a golden color lager malt that is kilned to produce a smooth mouthfeel and malty sweetness with gentle notes of honey, almond, and hazelnut. The color may be the same or slightly darker than a British Pale Malt. It is lightly kilned from quality, two-row, German spring barley and produces full-bodied beers. It is especially intended for for use in Vienna style beers, Festbier, and Märzenbier.
Appearance
Color: 2.8 - 3.9° Lovibond - Contributes a golden to orange color
Munich Malt is an amber to deep amber color lager malt that is kilned to produce full body and smooth mouthfeel with strong maltiness and rich aromas of light caramel, honey, and bread. While it is usually used a specialty malt, it has a high enzyme content despite its color, and can constitute up to 100% of the grist. It is typically used in dark lagers and ales, especially Munich-style lagers, various bock styles, and German festival beers like Märzenbier, Festbier, and Märzen.
Appearance
Color: 5.1 - 9.9° Lovibond - Contributes an amber to deep amber color
The flavor of this malt is very bready, with hints of raisins. Belgian Aromatic Malt is a kilned specialty malt from Belgium designed to boost both the malt flavor and aroma characteristics of a recipe. It is great for adding maltiness without the sweetness of caramel malts. Try Aromatic Malt at lower rates for any American or British style of beer or any recipe which is malt forward. Mashing this specialty grain is suggested as it has not been pre-converted like a caramel malt.
Appearance
Color: 19.3 - 26.9° Lovibond - Contributes a reddish hue
Good for Starch Conversion?
No, due to its low diastatic power it should not be used for more than 30% of the grist.
Biscuit Malt provides is a toasted malt that provides a warm bread or biscuit flavor and aroma, as well as garnet-brown color. This malt is produced in the roasting drum and has no enzymes, so it must be mashed with malts that have high diastatic power.
Appearance
Color: 23° Lovibond - Contributes a garnet-brown color
Victory Malt adds an aromas of baking bread and flavor of hazelnuts. It is well suited for Nut Brown Ales & other dark beers. Use it in small amounts to add complexity and warm color to lighter colored ales and lagers.

Smoked & Peated Malts
Smoked and peated malts are both dried with the heat and smoke of traditional fuel sources---most commonly Beechwood is used for smoked malt, and peat, of course, for peated malt.
“Rauch” means smoke in German, and smoked beers can be a unique change of pace, especially served with a selection of breads and cheeses.
With a color similar to a high-color pale malt, Rauch Malt produces strong beech smoke aromas and flavor with gentle notes of vanilla and honey. The smoke character is much more restrained than in Peated Malt. OK to use for up to 100% of malt bill. It is perfect for smoked lagers of the German tradition such as Bamberger Rauchbier and Kellerbier.
Appearance
Color: 2.1 - 3.6° Lovibond - Contributes a golden color
Utilizing peat from Aberdeenshire and Scottish spring barley, this malt is slowly dried using the peat as a fuel source to give fullest absorption of phenols by each grain. It is generally not recommended for use in beer due to the potential for phenolic astringency, but very good for old world whisky.

Caramel, Crystal & Other Saccharified Malts
Caramel’ or ‘crystal’ malt refers to malt that has been stewed to allow partial saccharification and then kilned to arrest sugar development. Further kilning results in sugar caramelization and the development of a wide range of flavors, aromas and color ranging from very pale (Dextrine Malt) to somewhat dark (120 SRM) and caramelized flavor. They are used in modest amounts for adding color, flavor, viscosity, and in most cases, some fermentable sugar.
It should be noted that the terms, “caramel malt” and “crystal malt,” could cause some unnecessary confusion. Just be aware that the “caramel malt” is the American term for similar malts that are called “crystal malt” by the British. Because the American home brewing tradition is descended from English roots, “crystal” is in wide use among home brewers.
A unique specialty malt used for recipe adjustment when more body is desired without any additional color or flavor/aroma. Dextrins are large sugars that cannot be fermented, converted into ethanol and CO2, by brewing yeasts. The effects of more dextrins in a finished beer are improved mouthfeel and head retention - foam stability.
Appearance
Color: 1.6° Lovibond - color contribution is trivial, similar to Pilsener Malt in color
Light caramel malts, such as CaraHell® 10L and Briess Caramel 20, contribute a fuller, rounder body and flavor along with a copper color, and gentle notes of caramel flavor. The resulting sweetness comes without contributing strong flavors. To avoid much color contribution, 10L is the most subtle, while 20L will be more noticeable in the beer.
Appearance
Color: 10-20° Lovibond - contributes deep golden to deep copper color depending on amount of use
Medium color caramel malts, in the range of 40 - 60 Lovibond, impart a deep golden color, rich sweetness, and mild to pronounced caramel and possibly toffee flavors. A versatile caramel malt for creating malty sweetness when used in higher quantities (functional maximum about 15% of grist) or a subtle added depth at lower rates. It is a mainstay specialty malt for American Pale Ale and IPA.
Appearance
Color: 40-60° Lovibond - Contributes deep golden to red hues
Dark caramel malts are kilned to a dark toast and impart more complex flavors than light or medium caramel malts. Lower usage rates can provide mild dried fruit, even fig-like character, and toffee notes while higher percentages increase the bittersweet burnt sugar character. Styles particularly well suited for this malt include Porter, Extra Special Bitter - ESB, Belgian Dubbel or Quad.
Appearance
Color: 80-120° Lovibond - Contributes red to deep red hues

Caramel-Vienna Malt - Belgian (a light caramel malt)
A light crystal/caramel malt made in Belgium. Due to the caramelization and low drying temperatures, its specific taste is achieved with light fruit character in addition to sweetness. It is used by many traditional Belgian breweries in Abbey-style beers.
Appearance
Color: 20° Lovibond - contributes deep golden to deep copper color depending on amount of use
Honey Malt is similar to German "brumalt." It is stewed like a melanoidin malt and lightly cultured with lactobacillus, resulting in a distinct honey aroma. Honey Malt also provides slight acidity along with its grassy/honey character. This unique malt adds complexity to beers.
Appearance
Color: 25° Lovibond - contributes deep golden to deep copper color depending on amount of use
Melanoidin Malt adds a deep amber to red-brown color and the flavor has notes of honey and biscuit. Melanoidins are brown colored molecules which are formed when sugars and amino acids combine (through the Maillard Reaction) at high temperatures. They are produced in wort by long kettle boils, and can also be added to the mash with this malt. With an intense malt aroma and unique brewing characteristics, this malt helps promote flavor stability with its high acidity, adds body, and produces a smooth mouthfeel.
Appearance
Color: 30° Lovibond - Contributes a deep amber to red-brown color
Carastan lends a burnished copper color and is bursting with the flavors and aromas of bittersweet English toffee, sourdough bread crust, and toasted hazelnuts. It is processed wet, followed by an extensive period of high-degree roasting, resulting in a uniquely English malt.

Black & Dark Roasted Malts
When grains are kilned or roasted beyond 200° Lovibond in color, they will increase the acidity of the mash; consider adding chalk to avoid sour flavors if using these grains.
Black grains don’t necessarily have to be mashed, as all the starch has been effectively burned out during the kilning. These grains consequently have little effect on the amount of fermentables in your wort. Extract brewers have a couple of options as to how to treat these grains. Unless you have a recipe indicating otherwise, you may add black malts to the boil uncrushed 10 to 30 minutes before the end of the boil. If you do that, tying the grain up in nylon or muslin bags makes them easier to remove at the end.
You may also crush and steep them, either with other grains or separately, according to the “Simple Infusion Mash” procedure. That will extract the “goodies” you want, even though you’re only looking for color and flavor, and not fermentable sugars.
Pale Chocolate Malt provides the nutty malt flavor of lighter toasted grains, but also some of the heavier flavor of darker roasted malt. It is lighter in color and milder in taste than regular chocolate malt, and can therefore be used in higher proportions than regular chocolate malt.
Appearance
Color: 220° Lovibond - Contributes dark brown color
Chocolate Malt provides a rich, dark color and roasted, sharp, even burnt or astringent flavors with intense chocolate and coffee notes. It is malted and roasted similarly to Brown malt but at higher final temperatures. When used in very small proportions it adds a nutty flavor, making it useful in Brown Ales as well as darker and black beers.
Appearance
Color: 500° Lovibond - Contributes dark brown to black color with deep ruby or garnet highlights
This black malt has been de-husked to produce rich color, body, flavor and aroma without the harsh flavors and astringency typical of dark-colored grains. It made for use where dark color is desired but malt-based bitterness is not desired, as in Schwartzbier and Black IPA.
Appearance
Color: 300° Lovibond - Contributes dark brown to black color with deep ruby or garnet highlights
Midnight Wheat Malt provides dark color with the smoothest flavor of any black malt making it popular for Black IPA recipes. The bitterness of black grains comes primarily from tannins in the grain's husk, as wheat has no husk there's no bitterness to remove. The result is a mellow roastiness that only becomes apparent at higher usage rates.
Appearance
Color: 550° Lovibond - Contributes dark brown to black color with deep ruby or garnet highlights
Black Roasted Barley provides coffee character, intense bitterness, and dryness to the palate and darkens foam color. It is responsible for the color and flavor of most traditional Irish Stouts, while also popular in Porters and used in very small portions for Red Ales and Scotch Ales.
Appearance
Color: 500° Lovibond - Contributes dark brown to black color with deep ruby or garnet highlights, and darkens the beer foam
