There are some bobbins beers about.   I want to warn others so you don't waste their money or sobriety.   Beers that I personally find undrinkable are:

VB (Victoria Bitter) - voted worst beer at lager festival. Overpoweringly sulphurous.
MGD (Miller Genuine Draft) - this used to be brewed at Ushers when I worked there. Sweet, bland.
Red Stripe - harsh, metallic, cheap lager sold at premium prices.
Charles Wells Banana Bread Beer - sweet, massively butterscoth tainted.
Cains Toffee Apple Beer - Like banana bread beer only more so.   Buttersocth (diacetyl) is seen as an off-flavour in the brewing industry usually.   A novelty product like a kiss-me-quick hat.
Cropton - all beers by this brewery have been horribly oxidised in the bottle or infected and tasted sulphurous.   Update for March 2008:   Tried M&S Yorkshire Bitter brewed by Cropton as I thought it must be quite good for M&S to sell it.   Very toffee-butterscotch like, with plenty of sweet malt flavour.   I couldn't finish it.   Still, its the best bottle of Cropton I've had so far.
Hampshire - In a cask these beers are excellent. In bottles is a different matter. Every 3rd bottle is oxidised beyond drinkability (survey of 16 bottles bought in 3 different shops). This makes their beer very expensive and very unpredictable. They used to be my closest brewery, so I'd like to champion them, but steer clear of the bottled stuff.   NB This doesn't apply to their Pride of Romsey IPAⁱ and other bottles with a better quality label.   I can only assume they use two different bottling lines.
Hesket Newmarket Brewery - Whilst up in the Lake District I noticed that this brewery did loads of different bottled beers.    So I bought five different bottles.  Every single one was tainted in some way & were thrown away.   They've won awards for their cask beer, so it must be the bottling line that's letting them down.   Just to prove me wrong someone bought a pint of HN at the Cockermouthⁱ Beer Fest and we all agreed it was pretty awful.

Ruddles Rhubarb - Holy Mother of Batman!   Do you like rhubarb?   Do you like Ruddles?   Well have a pint of Ruddles whilst you clean your saucepans with the rhubarb.   They definately do not go together.
