I went on a pilgrimage to what I thought was the brewery for Macintosh ales and is now nearly the only place to obtain them while their website is down. It was anyway hard to obtain them as you could only order on the first three days of the month, which gave them an air of exclusivity. Anyway, it turns out that it is not the brewery at all (it is brewed at Orbit in South London), but merely a picturesque bar in a courtyard just off Bouverie Road in Stoke Newington:-
