Too alcoholic beer

[Aramis]

Just curious about my last brew, in fact, 4 last brews, Im brewing Golden ale with 11.5ºP , I ferment with US 05 fermentis at 18ºC, after a couple of days, I take a sample (100 ml) and I feel my self drunk, I dont know why, I brew with 250 gr of yeast per 500 litres of wort, what am I doing wrong?
Hope for your advices
Best regards

First, I would suggest to calibrate your instrumentation.

Secondly, limit your sampling on an empty stomach.

All instrumentation is calibrated, and I drink samples after breakfast
any advice?
