I believe those original syrups came from a different company.
Whether or not Belgian breweries use those syrups, all I can say is that my Rochefort "homage" got a lot closer to the real thing once I started using them.

Those were the originally imported syrups. I believe they are just rebranded bulk Belgian syrups. They are quite good IMO.
Yep, they are. Brian imported and rebranded them. Several years later CSI was formed.
