Yep, Sinamar is made by Weyermann, it's an extract of dehusked Carafa that's never been heated, so minimal roasty flavor, just a whiff of malt. Reinheitsgebot compliant. It's cold extracted and concentrated by vacuum boiling to 3000°SRM. So it's like when you cold steep grain, but way more color and less flavor than any homemade hack could provide.
You can get it from William's Brewing. I thought MoreBeer had it too but I could be wrong.
