After years of partial mash, I will jump to the all grain with a BIAB. I order my grain bag + hop bag.
But suddenly, I've a brainwave and see the notice on my sanitary coupler : HT regarding the norm DIN EN 1451-1
So I guess I'm ok, but the guy on the shop cannot tell me if a 90 minutes boild will be ok for this kind of hop strainer:

Best regards,
Dom
