Gday, I've put on an amber ale (just a kit) and after running a few IBU calculators I think I've under hopped. Went with 20g chinook for a 10 minute boil, and another 20g thrown in with the first lot to steep for a further 30 mins. This was done as a tea and added to the kit wort before pitching. Looking for around 50 IBU and thinking I'll fall drastically short (went with LHBS guys advice and didn't think to check calculators first). My question is, can I boil up some more hops and add the liquid 2 days into fermentation or will I stuff the brew?
