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.

Thanks for the video, it looks like the brake master cylinder is leaking onto the exhaust system which causes the smoke. Can you look under the brake master to confirm? If so, this generic guide can help you change it out and I have included the specific instructions for your car in the diagrams below:
