![]() By random comparison, Fawcetts doesn't give the EBC method but the IOB colour is 120-140 degrees - i.e. To me, the data sheets/pages suggest that Crisps medium crystal has colour using the EBC method 250-290, and by the IOB method is 95 to 110. However that can be a minefield as colour of grain is an awful subject, with different measurement methods, conversions and predictions, few of which agree. So you should go by the specified values if small differences are important to you. There is no real standard for things like 'medium' and 'light', they are just relative statements it is down to the manufacturer how they apportion their own range and can especially vary between countries and traditions. It would be reassuring to know if there is a standard colour range for various roasts. It seems that the odd maltster have their own ideas of what ‘medium should be! Meanwhile I’ve purchased two more batches of ‘medium’roast crystal malt, one from the Maltmiller which was 150 EBC, and one from Brew UK (Warminster malting) that was 135 EBC, I asked my supplier ( who is a knowledgeable home brewer) what he thought of the great difference, he seemed to think there was little standard and the maltsters have their own standards, which I felt odd. I was supplied medium roast by my local supplier and it was Crisp medium 300 EBC, much too dark for my needs, the last couple of batches being 150 EBC, though I’m not sure of the origin. I know that there will be some variance betwen maltsters but nearly double seems a bit much. I ended up throwing 150g of this and 200g of Crisps (so called) light crystal (160-180 EBC 60-70 °L) into an ESB, it did come out much darker than it looked in Beersmith (20 EBC predicted by beersmith). Looking at other maltsters their medium crystal seems to come in around 140-160 EBC. Looking at Crisps data sheet it says their medium crystal is 250-290 EBC 95-110 °L. When I put it into Beersmith it told me this was an extra dark crystal! I wanted some medium crystal malt so ordered some of Crisps Crystal malt, ( called crystal 240).
