It is my first home brew. The batch size was 10ltr. I used 100% wheat malt of 2 kgs and used bitter orange peel of 36gm instead of Hop. The OG was1.02 and FG is 1.01 after 14 days of fermentation using Safale S04 of 11.5g at 25 - 27°C. After 14 days though it taste like flat beer but the colour is very light golden and it taste too much citrusy... I have attached an image of it Kindly suggest what may go wrong...
As farmersteve said that bottle isn't going to work for carbonating. You need a bottle that will be air tight, and to add a priming sugar.
Cloudy is to be expected from 100% wheat.
About the citrus balance, I think the 1.24oz / 36gm of peel was fine. And the amount of grain was good. You just had poor effenciency.
Your OG is about half what it should have been with that recipe I get a target OG of 1.044 at 75 % efficiency with the volumes and weights you provided. So it's going to basically have half of the other attributes of the malt too, which is why the citrus is over bearing.
Maybe if you can update with the exact kind of wheat you used and your brew process we can help with the efficiency problem.
