Over the course of lockdown I have bought beer from a lot of different breweries and one thing I have found is that almost without fail the best beers from them have being from their normal range, rather than the various random experimental or ’guest’ beers they do. Their is something to be said for a brewery which has complete nailed the malt, hops, water choice, yeast etc. and have brewed the same beer hundreds or thousands of times. Also I do not have the time or the inclination to brew enough to give myself the variety that want sometime I want a sour, or a good barley wine but don’t want 10L or more of it.
And those same brewery's may well have a house yeast which may have been in constant use for years so they know exactly how to get the best out of it.
