Veteran beer blogger Tandleman was recently reminiscing about mainly Northern and therefore largely undrunk by me beers that he misses from his past. Here are some of mine from breweries closed or brewed by others.

Fremlin's Bitter from Faversham aka Whitbread Trophy
Paines Bitter,St Neots.
Gray's Stock, Chelmsford
Rayment's AK, Furneux Pelham
All King and Barnes beers, Horsham, West Sussex
Young's Ordinary and Winter Warmer, Wandsworth, Greater London.
