Smoke coming from behind engine after short drive

After a journey, 5-10 miles roughly not far. Fan is on but the engine is not overheating (90*), the smoke appears to come from brake fluid reservoir or around that area, and brake fluid appears to be draining quickly. Turning A/C or heater on worsens it also, and a strong smell similar to burning alcohol is released and can smell in the car. Has been doing this since I got the car 2 months ago. Not after every single journey but about once or twice a week it happens. Smoke only starts after I turn the engine off and usually smokes for 5-10 minutes.
