Yes — Muscat of Alexandria is a vigorous vine that must be pruned annually to produce its large, aromatic berries. It is typically trained as a rod-and-spur system against a warm wall (essential in the UK). Without pruning, energy goes into wood, not fruit, and bunch quality declines rapidly.

Why is UK pruning timing different from American advice?
Most pruning guides online are written for US conditions and anchored to USDA zones. Britain's maritime climate gives milder winters but later, less predictable last frosts — from March in the south-west to mid-May in the north — so the RHS advises against winter pruning for most plants: it pushes out soft growth that a late frost then kills. Britain also has the nesting-bird law, which has no US equivalent.
