HARIO V60 Titanium 02 or Suiren 02?
Separate dripper construction from claims about the coffee in the cup.
HARIO lists the Titanium Dripper 02 with titanium and silicone construction. The Suiren 02 uses a wall-free rib structure and V60 02 filters. Both listings state a one-to-four-cup serving range. That range describes the products; it is not a recipe or a guarantee that every household mug fits the same interpretation of a cup.
Decide what you want to inspect before choosing: the body construction, filter support or the way the dripper fits your server. Check the manufacturer’s dimensions and care instructions against your existing setup. The Titanium listing gives 140 × 120 × 88 mm; that does not establish compatibility with every vessel.
For a personal comparison, hold coffee, grind, water and recipe constant before interpreting a difference in taste. Changing several variables while changing the dripper makes the result hard to attribute. Treat any preference as your observation under those conditions.
We have not brewed with these models or measured extraction and heat retention. Their different construction offers a concrete buying distinction, but it does not support declaring one universally sweeter, faster or better.
