Date sugar was a popular addition for a while, mostly to belgain brews. The sugarcane and date sugar mix jaggery has been a pretty popular beer addition as well. If I remember correctly using dates or date sugar was discusssed in brew like a monk? Sorry I don't have any personal experience to share but with a crate full of dates I think I'd be trying an experimental batch as well. cheers, j
oh yeah - dates and 70% cocoa dark chocolate is a pretty hard to beat snack
