On Friday evening, I cut up the very last bit of the Lanc I made on January 28th - it was about 100 days old and it was really, really good. I shared it with the cheesemaking class, as we made a wheel of Lanc and they all enjoyed it, too.
This is one that was good all throughout it's life, with a mild cheddar-like flavor early on, developing more character all along. It all depends on what you are looking for in a cheese, but I wouldn't hesistate to cut into a Lancashire at any time from 4 weeks to the full 90 days and still be assured of a good cheese. It held onto the creamy texture all throughout, too.
I have to say that this is the first aged cheese I have made that I feel was a complete success.
