I am making a new beer for a friend from Jamaica and I am having trouble getting enough sweetness. I am making a hibiscus ginger beer and I want it to be more like a Mikes lemonade or something equivalent. I know I could use caramelized grains like crystal malts, use malt-dextrin or lactose. I do not want to use lactose so that anyone with allergies can still drink it. Any suggestions would be great, thanks!!
