Klyukvenny mors (клюквенный морс) is the Russian cold-climate vitamin drink — wild cranberries gathered from the boggy north (Karelia, Vologda, Arkhangelsk), simmered briefly with water and sugar, strained, and served chilled. First documented in the 16th-century household manual Domostroy, which records the earliest recipe. It remains the standard non-alcoholic offering at every traditional Russian feast.
A cranberry drink — pressed cranberries cooked with sugar and water, then strained, served cold. Russian summer cooler that's actually tart-bitter, not sweet like American cranberry juice.
Russian mors uses only 100g sugar per kilogram of cranberries — the acid stays at 2.5% (vs 0.2% for American juice). The high acidity acts as a natural preservative; mors keeps without refrigeration for weeks.
Variations
Cranberry is the most common; lingonberry 'water' is the most celebrated old Russian version (mentioned in Pushkin's Eugene Onegin); the far north uses cloudberry — all traditional Russian berry drinks, differing only in the berry.
On the Palate
Where Klyukvenny Mors sits in the Russian flavor cloud
Simmer the cranberries only briefly and add the sugar at the very end — a short cook keeps the fruit's high acid and fresh color, and Russian mors stays tart on purpose, using far less sugar than sweet juice.
Ingredients
How it's made
6 steps · 30 min
- 11 min
Rinse 400g fresh or frozen cranberries. Crush them lightly with a wooden spoon to release juice.
Watch outCrush the berries just enough to split the skins and let the juice bleed out.
- 21 min
Place the crushed berries in a saucepan with 1.5 liters of water. Bring to a boil.
- 32 min
Reduce heat, simmer gently 8-10 minutes; the liquid should turn deep ruby red.
Watch outWatch for the liquid turning a deep ruby red — that's your cue it's done simmering.
- 41 min
Strain through a fine sieve, pressing the pulp to extract all liquid. Discard the solids.
- 51 min
Return strained liquid to the pot. Stir in 120-150g sugar (to taste); heat just enough to dissolve.
Watch outAdd sugar off the boil and heat only until it dissolves — no need to cook it further.
