Last reviewed by the teas.co.uk team in February 2026.

Twinings Buttermint is one of the brand's more distinctive creations: peppermint leaf with butter sweet flavouring that genuinely mimics a buttermint sweet in liquid form. Polarising. Lovers find it nostalgic and comforting (it tastes like the buttermints your grandmother kept in a glass dish); sceptics find it odd (peppermint should not taste of butter). Worth trying once for the curiosity even if you don't go back. Mainstream pricing.

The blend

Peppermint leaf (the cooling base), natural butter and vanilla flavouring (the differentiating "buttermint" character), occasionally a touch of caramel or honey equivalent flavouring depending on batch. The bag looks like standard peppermint; the surprise is in the cup.

How it tastes

Cooling peppermint hits first, then a sweet creamy buttery note arrives that genuinely tastes like dissolving a buttermint sweet in your mouth. The mint stays distinct; the butter does not turn the cup oily or rich, just sweet creamy. Drinkers who grew up on buttermints, mint humbugs, or after dinner mints will recognise the flavour and either love or recoil. Curator Rating: 4.9/5.

How to brew

1 bag in 200ml just boiled water.
Cover the cup; mint and vanilla aromatics both volatile.
Steep 5-7 minutes.
Drink black; the butter note already gives a creamy mouthfeel without milk.
For a dessert finish: float a small piece of dark chocolate on top and let it melt as you drink (mint chocolate effect).

Use cases

Post dinner dessert tea instead of pudding or biscuits.
Variety in a mint tea rotation alongside plain peppermint and Pukka Three Mint.
Sugar craving substitute (sweetness without sugar or calories).
Curiosity drink for adventurous tea drinkers.
Conversation starter cup for guests who think herbal tea is boring.

The buttermint nostalgia angle

Buttermint sweets are a classic British and American confection, butter, sugar, peppermint oil, churned and cut. The flavour is instantly recognisable to anyone who grew up in the UK or US in the 1960s-90s. Twinings essentially captured that exact flavour profile in a tea bag, which is either a charming retro flourish or a flavour mismatch depending on your taste. The product divides opinion in a way that plain peppermint does not.

Caffeine

0mg.

Vegan

Verify the pack. Some batches use plant based "butter" flavouring (vegan suitable); some use dairy derived butter flavouring (not vegan). The flavouring source varies by year.

Reflux warning

Like all peppermint teas, Buttermint may worsen acid reflux (peppermint relaxes the lower oesophageal sphincter). If reflux prone, pick a fennel or chamomile based dessert tea instead.
