Not that difficult really. 
Hardest parts are keeping everything sterile so it doesn’t get infected and have a constant temperature controlled environment so the yeast can doesn’t give nasty flavours.
It’s a fun hobby that when you do it right you trap good tasting rewards.
It’s my real life proof of work. 

 Keep going, that’s good for you - just by reading your words. I would be honored to drink one day, it would be nice to encourage you, and of course; to present me with the flavor. 🫂♥️🫀 

 You’re welcome to my citadel to shoot the shit, enjoy a brew and a steak anytime mate 

 🙏
