Frequently Asked Questions
Does lemon go well with coffee?
Yes! Lemon enhances the bright, fruity notes in coffee, creating a balanced and refreshing drink. It has been a classic addition in Italian espresso tonics and Vietnamese citrus coffee variations.
Can I use espresso instead of cold brew?
Yes! If you prefer a more intense drink, pull a double shot of espresso and pour it over ice, then add lemon and sweetener. This version is more concentrated and resembles an iced espresso tonic.
Is Lemon Cold Brew acidic?
Cold brew itself is less acidic than hot-brewed coffee, but adding lemon increases acidity slightly. However, this acidity is refreshing rather than overpowering, similar to a lemonade-style drink.
Can I add milk or cream to Lemon Cold Brew?
Milk doesn’t pair well with citrus, as it can curdle. If you want a creamy texture, try oat milk or almond milk, which are more stable in acidic drinks.
How long can I store Lemon Cold Brew?
Cold brew coffee lasts up to a week in the fridge, but once mixed with lemon, it’s best consumed within a few hours for maximum freshness.
