Soy is often the first non-dairy milk people try. We find it has a strong flavour and a very watery consistency. It doesn't heat well & often splits.

Oat milk behaves more like dairy due to its thicker consistency. There are many well developed options, including 'barista' editions.

Almond is another watery plant milk, which means it doesn't perform well for thick frothy coffee. It also runs very sweet, even the 'unsweetened' versions.
