As per title, Tesco currently have 500ml bottles of Fullers Organic Honeydew beer for £1.00.
This is 5% ABV and the Fullers website says:
'Organic Honey Dew is the UK’s best selling organic beer. Light and golden with a zesty edge and a bitter-sweet flavour, Honey Dew is a naturally palatable brew that is Soil Association approved.
Served chilled, Organic Honey Dew offers both refreshment and an unbeatable taste. The real organic honey in the brew gives a gentle sweetness that appeals to a wide range of people, even those who perhaps wouldn't usually drink beer, making it a very popular choice!'
The next cheapest for these bottles is 3 for £4.00 at Asda.
