15g of medium grind mixed in 250ml of water is a small amount. Id then say it's your personal chemistry that didnt agree with it, or maybe some other factors.
Melo is different, but cant guatantee your body will agree with it. It's the most popular cultivar at our partner kava bar in Auckland though.
I would suggest following @Alia 's advice. Prep 250-300ml to your 15g. Strain it well in Kava Europe's strainer (or equivalent, note both KE and our strainers are customised to our grind type, if you use other strainers they may not be fine enough to filter kava well). Drink it all at oncs or in two portions (each drunk in one go). Eat some fruit immediately after kava (apples or oranges work well).
