Long time lurker, first time poster.
Recently, I tried my hand at brewing a Terrapin Golden Ale clone (available in GA). After the boil and prior to pitching, the wort seemed great (sweet/good color). I pitched yeast at 68F and fermented at 68-70F for two weeks. I hit my projected OG and FG and the beer tasted great (flavorful, tasty, great color). It even almost seemed to have a slight carbonation, but unless that is relevant, it may have been my imagination. Finally, I bottled the beer and primed using pure organic cane sugar as I have in the past.
In an effort to try to understand the conditioning phase better, I thought I would try a beer every week or so to see how it changes. Upon opening my first beer after 4 days in the bottle, it tasted weak and had a tiny fraction of the flavor of what I experienced. It didn't seem to be overly alcoholic (original estimated abv: 4.6%), just weak with a decent carbonation but no where near finished priming phase.
What's going on here? I cant see that the flavor would return after the typical two week recommended conditioning phase and can't explain why it had the flavor strength of a light lager style beer if it tasted great at bottling. I am really careful about being sanitary and not contaminating my batch and have brewed multiple All-grain batches with no issues, just never tasted one this early after bottling.
I've considered a gusher bug, but wouldn't the abv rise as the bug did it's thing?
Details of brew below. Let me know if there is any other relevant info that might help.
