Treen's Classic

Deep amber, malty bitter beer with an intensity of flavour which belies its modest strength. Caramel and soft fruit flavours are balanced by a hint of dark chocolate and a spicy hop bitterness.

Our debut beer. This classic best bitter has quickly become a stalwart in our range.

Treen's Sunbeam

Golden Ale with a complex nose and well balanced body. A full citrus aroma with floral and spiced notes rides above delicate malt flavours of grain and caramel.

Treen's Resolve

Full, rich and very dark. This Premium Ale is brimming with flavour. Deep, roasted malt competes with dark chocolate and coffee culminating in a smooth, comforting finish.

Strong, dark and warming. This steadfast and dangerously drinkable beer is comfort food in a glass.

Treen's Krowsek

Full bodied, amber Special Bitter. Spicy hop and soft fruits on the nose over malt flavours of biscuit and caramel ending in a refreshing bitterness.

Krowsek, meaning irritable in Cornish, is a satisfying beer which will help wash away that teasy feeling.

Treen's Mariner

Traditional IPA. Strong, golden ale with a full mouth-feel and crisp bitterness. Classic British hop aromas of flowers, grass and spice above clean cereal malt flavours.

The Age of Sail required robust ales to survive long sea journeys. Thus the formidable India Pale Ales were born.

Treen's Hirra

Golden lager with delicate flavours of grain and a hint of grassy hop on the nose leading to a clean dry, refreshing finish.

Named in Cornish meaning “Longer” we draw on the Bohemian tradition of storing the beer for months at lower temperatures to make sure it is as thirst quenching as possible.

Treen's Local

Well rounded, golden ale. Grassy, floral hop nose above an easy drinking biscuit malt base with a hint of caramel. Soothing body with a refreshing bitterness on the finish.
Brewed to support CAMRA Kernow’s “Support Your Local” pubs initiative we created an ideal accompaniment for a relaxing trip to your local.

Treen's Smoulder

Smoked ale. Ruby in colour with a rich nose of wood smoke. Full-bodied with hints of fruit under a distinctive savoury smoke-house flavour.

Brewed in homage to the Rauchbier of Bamberg this smoked ale is a warming treat for the nose and palate.

Treen's Cloud Cuckoo

This warming winter ale is matured for a minimum of 6 weeks in our cellar to ensure a full and smooth flavour. Deep ruby, full-bodied strong malty ale. Plum and soft fruits dominate followed by a smooth roasted finish.

The name reminds us of our early years “Cuckoo Brewing”.
