Geoff, anything involving hops are remarkably sensitive to temperature and time since brewing - super fresh pale ales taste very different to those even a couple of weeks old. Cloudwater are now using their own cold chain vans to ensure freshness. A month plus from brewing and they really lose their vibrancy. Also certain recipes don’t scale up well.
Chai made in Himachal Pradesh by boiling tea leaves and cardomom in fresh buffalo milk, amazingTravelling around India in my early 20s I have vivid memories of unbearably long and uncomfortable bus journeys. These were always punctuated by roadside stops in the early hours of the morning for a warm cup of chai spooned out of a concoction brewing on the side of the road. It was always extremely good - just enough sweetness, milk and spice to revive and refresh after all the bumps and no sleep!
