I did my standard 5 finger discounted history, but it was nice to be able to type out everything else without having to look anything up! The next one up my sleeve will be less derpy...Only joking mate, I always wonder what things do when I visit places and try to figure them out or do further research later on. Good to have someone who knows explain the process
Caustic is the industry standard cleaning solution, so any non porous kit (ie not the oak tuns) are cleaned with it, so mainly the pipework, charger tanks and mash tun. They had no acid lines so I would assume after a thorough rinse with water steam would then be passed through to sterilise everything instead of peracetic acid which is what is generally used now, it is a contact sanitiser that doesn’t require a rinse off because it breaks down when exposed to air. The oak would be cleaned with steam and possibly citric acid. They would have the insides scraped down by hand from time to time because you get a natural mineral build up called beer/wine stone which is precipitated out during fermentation, it even sticks to stainless steel vessels. It’s either elbow grease or nitric acid to shift that, and nitric would eat through wood in seconds!
I love being able to combine exploring with my brewing knowledge for once!
Yeah it’s fucking horrible stuff but it chews through grime very well, as well as your skin! I’ve got loads of small scars from getting drops on my arms and not noticing in time!
My brewery is way more modern than this!
