I even brew it and bottle into the Grolsch flip top bottles, which I believe is the only way to drink a good beer!!
The castors? or the bench?
The bench is 100 by 100, however I mucked up by edging it with Merbau, I should have (and will replace the edging) just done breadboard ends.
The castors are good quality rubber ones, about 50mm diameter. I have skirting on three sides of the island, and the fourth skirting is shorter allowing me to lock in the brakes.
Cheers
