After a break of over 25 years, I returned to home brewing during the first lockdown.
Things have certainly improved for the home brewer over that time. A lot of the information in the older books is still relevant, I learned a lot, particularly from brewing lager by John Alexander although back in the day there weren't a lot of lager yeasts available !
I loved brewing Dave line's Irish stout, using a starter made from yeast harvested from a Guinness original, (when it was bottled conditioned).
