Walnut Leaf Wine
Walnut leaf wine has a long history throughout Europe, where walnut trees have been valued not only for their nuts but also for their aromatic leaves. Traditional country winemakers discovered that young walnut leaves produced a remarkably well-structured wine with subtle spicy and nutty characteristics that developed beautifully during bottle aging. Unlike wines made from walnuts themselves, walnut leaf wine is light in colour and delicately flavoured, relying on the leaves' aromatic compounds rather than the rich oils found in the nuts. Given time, it develops into one of the most complex and rewarding wines in the Herbs & Leaves Collection.

FAQs
Does walnut leaf wine taste like walnuts? Only subtly. The wine develops gentle nutty, spicy and honeyed notes rather than the rich flavour of walnut kernels.
Can I use mature walnut leaves? No. Mature leaves contain much higher levels of bitter compounds. Always harvest young leaves in late spring or early summer.
Can I dry or freeze the leaves? Yes. Both methods preserve the leaves well, although fresh leaves generally produce the finest and most aromatic wine.
Why isn't additional tannin required? Young walnut leaves naturally contain sufficient tannins to provide good structure and excellent ageing potential.
How long should I age walnut leaf wine? At least one year is recommended. It continues to improve for several years and is one of the best long-aging herb wines
