Coffee Science & Extraction

Coffee is one of the most complex ingredients in drinks.

Small changes in grind size, brew ratio, contact time, temperature or filtration can dramatically alter flavour, aroma, sweetness, acidity and bitterness. That complexity becomes even more important when building exceptional coffee liqueur and coffee cocktails.

At NORSE CODE, we believe extraction expertise is one of the most overlooked skills in the coffee liqueur category. Many brands focus on sourcing coffee or using trendy brew methods, but far fewer understand how extraction controls flavour clarity, balance and stability.

Our Coffee Science & Extraction articles explore the deeper technical side of coffee — from brew methods and flavour chemistry to extraction theory, filtration and the science behind preserving delicate coffee character in spirits and cocktails.
