"Summer's best, cheapest bubbly is this stylish Spaniard from Codorníu. Made by the método tradicional, the same method used in Champagne, from the usual trio of Penedès grapes, parellada, xarel-lo and macabeo, this sub-£6 bargain won’t hang around for long. So if you fancy a simple, zesty, citrus, slightly frothy, 11.5 per cent alcohol fizz, this is for you. "
