Tea! Tea! And more tea!!!
I drink about 3-4 litres of tea every day. English Breakfast tea (Taylor's of Harrogate,) Yorkshire Tea (it's not for them wot's from Surry!) Keemun and Assam. Hot and black, no sugar or lemon. For a rainy cold November day reading by the window, nothing beats a steaming mug of Lapsang Souchang. (Except perhaps a good single malt.... Nah... TEA!!)
