How do you measure volume in a KeepCup?

Our original barista standard range was designed to mimic the functionality of a takeaway cup. The cups were designed to replicate takeaway cup volumes, commonly described in fluid ounces. The volume was measured to brim full using a press on lid. The Original range is designed to enjoy your coffee lid on or off and to facilitate latte art and a great pour. New designs like Cold Cup have a press in lid which slightly adjusts internal volumes, but the overall idea remains the same, to create an enjoyable drinking experience you want to reach for again and again.

What drinks are best for a 12oz KeepCup?

A 12oz KeepCup (around 340ml) is the most popular size, often equivalent to a “medium” takeaway coffee at cafés. It offers a balance between volume and portability, making it versatile for a wide range of drinks.

Specialty Coffee: Perfect for lattes, cappuccinos, and flat whites if you like a little extra milk. It’s also a great choice for larger long blacks or Americanos when you want a longer coffee without it being too diluted.

Specialty drinks: Works well for chai lattes, matcha lattes, mochas, and hot chocolates where the extra room balances flavour and milk.

Cold drinks: Ideal for iced lattes, iced long blacks, cold brew, and even small smoothies or juices.

Tea: Generous enough for a full black tea, green tea, or herbal infusion, especially if you enjoy a larger cup to sip on throughout the morning.

Batter up! the 12oz KeepCup is the “all-rounder” — great if you like a medium-size coffee, want extra room for milk-based drinks, and want versatility for hot and cold beverages.
