12oz Reusable Coffee Cups

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.

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.
