Lovibond (°L) is the scale used to measure the color of malted grain and other brewing ingredients. Every grain on your homebrew shop shelf has a Lovibond rating that tells you how much color it contributes to your beer, from 1°L for pale pilsner malt to 600°L for black patent. Understanding these numbers lets you predict your beer's color before brew day and adjust grain selections to hit any target on the SRM spectrum. It also tells you something about flavor: higher Lovibond generally means more Maillard reaction products, caramelization, and roast character.
Lovibond ratings for common brewing grains
| Grain | Lovibond (°L) | Flavor contribution | Typical use rate |
|---|---|---|---|
| American 2-Row | 1.5–2°L | Clean, neutral malt base | Up to 100% of grain bill |
| Pilsner malt | 1.5–2°L | Light, slightly sweet, subtle grain | Up to 100%; lager base |
| Pale ale malt | 2.5–3.5°L | Slightly more malt character than 2-row | Up to 100% |
| Vienna malt | 3–4°L | Light biscuit, toasty, slight sweetness | 10–100% |
| Munich malt (light) | 6–8°L | Rich malt, bread crust, honey | 10–60% |
| Munich malt (dark) | 10–15°L | Deep malt, toasty, slight caramel | 5–30% |
| Biscuit / Victory malt | 23–25°L | Biscuit, bread crust, nutty | 5–15% |
| Crystal/Caramel 10 | 10°L | Very light caramel, slight sweetness | 3–10% |
| Crystal/Caramel 40 | 40°L | Caramel, toffee, light dried fruit | 5–15% |
| Crystal/Caramel 60 | 60°L | Rich caramel, medium body | 5–15% |
| Crystal/Caramel 120 | 120°L | Dark caramel, raisin, dried plum | 3–8% |
| Special B | 115–135°L | Dark fruit, raisin, fig, slight roast | 3–8%; Belgian dark ales |
| Brown malt | 65–80°L | Coffee, biscuit, dry roast | 5–20%; porter, brown ale |
| Chocolate malt | 350–400°L | Chocolate, coffee, mild roast | 3–8% |
| Carafa I / Dehusked chocolate | 300–350°L | Smooth dark color without harsh astringency | 3–8% |
| Roasted barley | 300–500°L | Dry, coffee, espresso; dry stout character | 3–10% |
| Black patent malt | 500–600°L | Harsh, acrid roast; use sparingly | 0.5–3% |
How Lovibond converts to SRM
Lovibond and SRM are approximately equal for values below 10, a 2°L malt and 2 SRM color are essentially the same measurement. Above 10, the scales diverge slightly. The SRM of the finished beer is calculated by totaling the Malt Color Units (MCU = grain weight × grain Lovibond / batch volume) and applying the Morey formula: SRM = 1.4922 × MCU^0.6859. Brewing software handles this calculation automatically when you enter grain weights and Lovibond ratings.
Common Questions
Why does the same grain have different Lovibond ratings from different maltsters?
Malting process variability, kiln temperature, time, and moisture content during kilning, produces slightly different color results even from the same base grain. A "Crystal 60" from Briess may have a slightly different actual color than a "Caramel 60" from Weyermann or Simpsons. Most are close enough that recipe adjustments aren't necessary, but if you're switching maltster for a style with tight color requirements, check the specific lot's Lovibond on the maltster's spec sheet. Brewing software databases include maltster-specific values for common grains.
When should I use Carafa (dehusked) instead of regular chocolate or black malt?
Dehusked roasted malts (Carafa Special, Blackprinz, Midnight Wheat) produce dark color with significantly reduced astringency and harshness compared to regular roasted barley or black patent malt. The husk is where most harsh tannins and bitterness in roasted malts originate, removing it before roasting produces a smoother, more rounded dark color addition. Use dehusked roasted malts when you want dark color without strong roast flavor (dark lagers, dry Irish stout where smoothness is a goal) or when you're adding very small amounts for color adjustment and don't want the flavor impact. Regular black patent and roasted barley are appropriate when roast character is intentional and desired.
