CSI Syrup Shelf Life?

Anyone know, in practice, what the shelf life of these syrups are after opening? CSI says on their website that thy are good for 3 weeks or so after opening but I have trouble believing it would be that short.

Also, anyone use their soft sugars with good results?

I used half a lb of their d-180 six months after using the first half. Smelled good, and made a good beer. I kept it in the fridge. Otherwise, I have used their d-90 and d-45, and think they are great. In fact, I just kegged a Belgian single, and a saison that used the d-45, and the samples were quite tasty.

That’s good to know. I make 1 gallon batches so 1 lb for 5 gal. = .20 lb for my batches. If I bought a pound of all  their varieties of have stock for the whole year basically.

Anyone use the soft sugars? The brun leger and brun fonce?

I think they have extremely long shelf lives. I have had them stored in hot warehouse conditions for  over a year with no issues.
