The range do a really good brew bucket . Bigger than most at 32ltr which gives more head space so less likely to foam out of the airlock when fermenting, and top quality for a tenner. If they still do it.
You need an airlock. A syphon tube and save some fizzy pop bottles (free) (don't bother with a barrel, they're crap, and bottles fit in the fridge lol.
A long plastic spoon or paddle to stir it. And Milton sanitizer for babies bottles is good for sanitising equipment.
Wilko's is decent for kits and equipment. some online sellers are better.
You can buy a full starter kit off them.
Yes it is easy. The most important thing is cleaning and sanitising equipment.
Ps, that was either a Wilko's chocolate stout or a Cooper's Irish stout.
You can either use normal sugar, dextrose or liquid malt for fermentation.
I use the latter two for better body, head and taste .
I use normal sugar for carbonation. I have another bucket with a tap I rack off the beer too with around 170gm sugar to secondary ferment to add carbonation. I fit a bottling wand to the tap to make bottling easy peasy
Pps, look on Facebook sales for 2nd hand equipment.
