I found Cornish Best from St Austell Brewery in the Ostrich Inn which is one of the best Peterborough pubs. St Austell are a proper old Cornish brewery who have just hit their 170th birthday, you'll probably recognise the name from beers like Tribute and Proper Job which turn up absolutely everywhere. Cornish Best pours a fairly transparent oak brown with a reasonable white head, basically it looks like a proper old English bitter, which is exactly what it is. The beers aroma is a little fruitier than I was expecting but there's plenty of traditional bitter biscuit malts in there too.
Cornish bitter has a thin but smooth texture and at 3.5% it's certainly a decent option if you're heading out for a long session and need to watch your intake. The taste is pleasant, there's a few light fruity notes which even out nicely with the more expected malt flavour. There's nothing new or exciting about Cornish Best, but it's not a new or exciting beer, it's a beer that is old, traditional, and suits most palates. I think most people would be happy with a pint of Cornish Best from St Austell Brewery so I'm quite happy to give it 7 out of 10.
