There are a number to choose from. In Scotland, Rose Murray Brown MW (01334 870 731; www.rosemurraybrown.com) runs courses in Glasgow, Edinburgh and St. Andrews (£125 per person for four sessions) as well as hosting foreign trips.
In Suffolk, David Roberts MW (01359 271795; www.davidrobertsdomaines.com) hosts a relaxed and informative six-part Introduction to Wine Course at stately Ickworth House, near Bury St Edmunds, starting each February (£285 per person).
And in London, I would suggest either Michael Schuster’s Winewise (020 7254 9734; www.michaelschusterwine.com) or the Berry Bros & Rudd Wine School (020 7396 9685; www.bbr.com), both of which run several courses aimed at different levels of expertise.
