Beer Styles Best bitters, milds, porters, (not stouts) Usage Rate Up to 10% With Medium Crystal those intense caramel flavours of thick treacle toffee are developed. To achieve these kinds of flavours the temperature is raised a further step from Light Crystal and the sugars darken further still giving the beer a deep copper hue. Remember that Crystal Malts have no enzymes or FAN preserved so be careful with the addition rate in your mash. You want to add enough to get the depth of flavour desired, but not so much that you will have issues in fermentation due to a lack of nutrients.
