You'll find it in the Weyermann malts, they just give their crystal malts weird names. I think the cara bohemian is pretty close to 90.

You can get Briess Crystal 90 (180 EBC) fromHamstead Brewing Centre which is a bit lighter than the dark crystal that Rob sells.

This is crystal 90 - bought some from MM not so long ago (EBC240 = 90L)

SRM 90 = EBC 180 roughly; ie EBC = 2 x SRM

For all intents and purposes; 1 Lovibond = 1 SRM (Standard Reference Method) = 2 EBC (European Brewery Convention)

I didnt think that was the case... e.g.

90L = 122SRM = 240EBC

Well they are incorrect. The Lovibond system was set up by Mr Lovibond (surprisingly) in 1883 based on determining colour by light, this was later modified to the Series 52 Lovibond scale. In the '50's in America the use of spectrophotometers measuring wavelength of light led to the Standard Reference Method (SRM) which approximates the Lovibond Series 52. The European Brewing Congress (EBC) uses a different wavelength for measuring and is ~1.97 x SRM. All systems go a bit tits up when measuring darker malts/liquids.

Weird, cos looking online there's a bunch of sites and posts on forums suggesting that the relationship is:

SRM = 1.3546 * L - 0.76

e.g. Wikipedia https://en.wikipedia.org/wiki/Standard_Reference_Method

it looks like this is what brewtoad is using...

I always used this when translating recipes that state a crystal malt in Lovibond. Would be good to know if I'm doing the wrong thing. At darker colours the above gives quite a big difference....

This is probably something to be adjudicated by our more learned colleagues. I just get my information from reading books, and from John Mallett's book Malt;

"Wort and beer colour is assessed and reported using one of 3 methods; Lovibond, SRM or EBC. The Lovibond method is the oldest and uses direct comparison of a sample to coloured glass slides. The more modern SRM and EBC methods photometrically measure the light absorbance of filtered, clear samples at the light wavelength of 430 nanometers (deep blue).

SRM values were created to agree with the original Lovibond scale and are fundamentally interchangeable. EBC and SRM values differ by a factor of 1.97, making EBC roughly double that of SRM."

Excuse the pun but beer colour is a whole load of dark arts and is a can of worms. When selecting malts, you should only be looking at flavour attributes rather than what colour it is.

Darker crystal malts have different flavour contributions than paler crystal malts though. So ideally you do need to be matching the colour if you are using a supplied recipe to brew that beer

Thanks for the link, another quality post from Graham. I know it is Sunday morning, but he started losing me when talking about SRM and "adjusted" SRM. However I think it proves your point on the colour calculation from Lovibond, although for malts it is probably good enough to use x2. None of us really know without testing. I recently made a stout that was dark and then added 160ml of caramel, which made it very dark :lol: but I wouldn't know what the EBC is, if you hold it right next to a light bulb you can't see through it :lol:

Over here we have a simple choice of crystal or caramel malts (from the MM, approx. EBC), caragold (10), pale (60), standard (120), dark (240) and extra dark (350). US caramel is available in steps of 10 from 10 Lovibond. I've been using some of the Briess malts from a shop near me and found them to be very good.
