Confused over the colour ratings of Roasted Barley. I usually use SRM in Beersmith but thought why not go with EBC as the malt analysis sheets use the same. So I converted an Irish red recipe and updated the details for my Roasted Barley as per the sheet, 1350 EBC. The default roast I had used before was only 300SRM or 591EBC. Obviously as I change my grain to the correct 1350EBC my colour goes black! Now I'm only planning on using 150g in a 20L batch. I've seen others use similar amounts so don't think it looks too much. What's the deal, is the stated EBC value wrong or will I get an Irish black if I use 150g of the stuff? The only other time I used my Roast was for a kit stout so no idea if it changed the colour at all. I think I also grabbed the roast barley from brewcraft shop so no idea if it's the same stuff as Liberty anyway.
Does Roast Barley change colour much between suppliers?
There are two methods of measuring EBC (Traditional and new). The traditional method has a higher value than the new for the same malt. If 1350 is by the traditional system then the new would be roughly 1000 (I think??) and a little over 500 SRM.
Yes different malting houses produce different coloured malts - for roast barley 300 to 600+ SRM at a guess - so a huge range.
If the malt is that dark then I guess it would have quite a strong burnt coffee flavour - you will get some of that in the beer and the beer might come out browner rather than red.
