Pleased to hear you were positively surprised by the flavour. For now, we only have sweet flavours. But we're going to test some new flavours in the near future, and there's some savoury options to test then as well. I cannot guarantee that those will make the cut and be added to our flavours though, but we're working on it!
With regards to warming up your Queal: It can be warmed up, but increasing the temperature of the mix will decrease the amount of the vitamins, as they degrade in heat. So that's up to you!
