I have had quite a bit of of Felton road over the years (even before becoming a TWS member)
I found that Cornish and Calvert were the sweet spot: you do see the step up from Bannockburn, and have never quite been able to appreciate the Block cuvees when taking into account their price (maybe I drank them too young? but the Felton road drinkability matrix says they are ok to be drunk young!). In recent vintages, Cornish Point was my preferred cuvée
Obviously, the recent price increases are challenging my personal stance as the price gap between Bannockburn and Cornish Point/Calvert has been increasing…
If the dinner had been in London or somewhere equally accessible I would have been there like a shot, but it is not the sort of dinner you want to drive to, and the public transport options for me are limited, complicated and expensive. Ruled it out for me I’m afraid.
