Bottled my first batch, a Sierra Nevada Pale Ale clone, two weeks ago. I stored at about 55-60 degrees for a week before moving to frig. I tried one last night, and there's little to no carbonation. I used about 4 oz of corn sugar for about 48 bottles, boiled it for a few minutes before racking on it. I think the beer tastes OK, you can really taste the hops even though it wasn't dry-hopped, but there is no head, no tiny bubbles, no crispness. I'm sure it's still green, but should I be expecting more carbonation by now? Should I open up half of them and put a teaspoon of sugar in and try again?
