Second All-Grain IPA Tastes Bitter From Keg

[gmcardle]

Hey guys, ok so I've just brewed my second all-grain IPA, two weeks in primary and then kegged. I live in Midleton, Co. Cork and decided to use 100% tap water as I need to do more research on mash ph, water treatment etc. Anyway after a week in the keg at 12psi I tried a sample, it's not the worst however I am getting a harsh bitter taste that I don't often get when tasting commercial IPAs. I've no idea what might cause this bitter, watery taste and was wondering if it could be anything to do with:

A. The fact that I didn't use spring water or any water treatment?
B. That this beer is still 'green' and needs time to age?
C. I didn't dump the first glass or two I pulled from the keg?
E. I've possibly oxygenated the wort somewhere during my process?
F. After kegging at 12psi for a week I purged the head space completely before pouring as there was too much pressure?

Hoping someone might have a answer : (

Most likely B. I wouldn't consider any of the other options until you've given the beer time to to condition fully. 3 weeks from pitching yeast to drinking is not a common timeframe for home brew.

I've attached the recipe below, it's a Hop Bursting IPA

Hop bursting to me would be a straight doubling of those additions
