How Many Syns in Pimms No.1?

By Jenny Updated

Pimms No.1 is the quintessential British summer drink, a gin-based fruit cup with herbal and citrus undertones that practically demands a deckchair, a punnet of strawberries and a tennis match on the telly. For Slimming World members trying to enjoy a sunny afternoon without derailing their week, Pimms sits squarely in the alcohol section of the syns book, with a 25ml measure costing roughly 2 syns and a more generous 50ml pour weighing in at about 4 syns.

Because the spirit itself is around 25% ABV, the syn count is lower than a standard 25ml gin or vodka, which makes it a relatively friendly choice when you want something long, slow and refreshing rather than a quick shot. The trick, of course, is the mixer.

Traditional Pimms is built with lemonade, mint, cucumber, orange and strawberry, and the lemonade is where most people accidentally double their syn spend. Swapping in sugar-free lemonade or diet ginger ale brings the total drink back to just the syns in the spirit itself, leaving room for a treat later.

The fruit and cucumber garnish is free, so pile it high in a tall glass for that proper jug-of-Pimms feeling without any extra cost. It is worth measuring carefully though, because Pimms is one of those drinks that slips down dangerously easily and the syns add up faster than you might think across an afternoon.

A jug shared between four, made with diet mixer and plenty of ice, is a genuinely sociable way to mark the start of British summertime while keeping your weekly syn allowance intact. Pair it with a free salad-and-new-potato spread and you have a Wimbledon-worthy lunch that still leaves you on plan come weigh-in day.

Lower-syn alternatives

Swaps that keep the feel of the original without the syn hit.

Prosecco

3 syns per 125ml flute

A glass of Prosecco at 3 syns delivers a celebratory fizz that pairs well with summer gatherings. It is slightly higher per serve than a single Pimms measure but feels more like a complete drink without needing a mixer. Top with frozen berries for extra flair.

Gin and slimline tonic

2.5 syns per 25ml

A 25ml gin with slimline tonic costs roughly 2.5 syns, making it a similar option to Pimms. Add cucumber and lime for a refreshing, low-syn long drink. The flavour profile is different but the summer-garden experience is comparable.

Sparkling water with fruit

Free

For a zero-syn alternative, sparkling water with sliced strawberries, cucumber and mint delivers the visual and aromatic experience of Pimms without any alcohol. It is the smartest choice on days when you want to save all your syns for food.

FAQs

How many syns in Pimms?

Pimms No.1 is approximately 2 syns per 25ml measure on Slimming World. A 50ml double is around 4 syns, and a generous 75ml pour climbs to roughly 6 syns. A ready-to-drink can with lemonade (250ml) costs about 9 syns. The syns come from the alcohol itself, so using sugar-free lemonade as your mixer keeps the total to just the spirit's syns.

Is Pimms low in syns on Slimming World?

Compared to stronger spirits, Pimms is relatively gentle at 2 syns per 25ml, thanks to its lower 25% ABV. A standard gin or vodka at 37.5% would cost closer to 2.5-3 syns for the same measure. The danger is in the mixer: regular lemonade adds another 3-4 syns per glass, while diet lemonade keeps it at just the 2 syns for the spirit.

Can you drink Pimms on Slimming World?

Absolutely. A 25ml measure with diet lemonade, cucumber, mint and strawberries makes a gorgeous summer drink for just 2 syns. The fruit garnish is Free, so pile it in. Two 25ml pours across an afternoon is 4 syns total, which fits comfortably into most daily allowances. Avoid the pre-mixed cans at 9 syns unless you have budgeted generously.

How many syns in a Pimms and lemonade?

A Pimms and regular lemonade made with a 50ml measure is roughly 7-8 syns total because the full-sugar lemonade adds 3-4 syns on top of the 4-syn spirit. Switching to diet or slimline lemonade brings the total back to just 4 syns for the 50ml measure. Always use sugar-free mixers to keep the syn count as low as possible.
