Yes, it's completely normal and harmless! In fact, it's a sign that your beer is unfiltered or unpasteurised, which can enhance its flavour and character. Those floating particles are natural yeast sediments that often occur in such beers. Hazy, wheaty, or bottle-conditioned beers may have a solid layer at the bottom, resulting in a thicker and cloudier appearance when poured into a glass.
If you prefer a clearer pour, we recommend pouring your beer slowly and steadily to minimise the disturbance of the yeast sediments. Some brewers even suggest stopping the pour before the bottle or can is completely empty to keep most of the yeast sediments inside. So, rest assured, those floating particles are part of the beer's natural goodness and won't affect your enjoyment.
