I recently put down some Isinglass Finings on a mail order. The goods arrived today but the Isinglass was out of stock so I've been sent a Kieselsol/Gelatine product instead.
Now I like my beers pure and free from chemicals so I'm dubious about this one, I've heard of Gelatine finings but what is Kieselsol? It also mentions Citric Acid (E330) and 'Preservative' (E202) on the label. They don't sound good.
What do you guys reckon? Should I chuck it in the brew or chuck it in the bin?
