Does anybody know if there is a Cornish cream stout in a shop or on the web as i can not find it?

You might have some luck checking local specialty beer shops or visiting the websites of breweries in Cornwall, as they may offer online ordering. Additionally, platforms like Untappd or BeerAdvocate can help you find specific beers and their availability. If you're looking for a particular brand, it might be helpful to contact the brewery directly for the most accurate information.
