Very decent lightly sweet taste with plenty of carbs, an impressive 80g of carbs (1:0.8) in just 600ml of water. No gastric discomfort, and honestly quite a nice taste and will definitely continuing to use this. Sachets are large (but expected), and price on subscription is great compared to other brands.
