it will be nothing like Pilsner thats for sure, more like Pale Ale if you used Ale yeast. From what I know Coopers uses same ale yeast (yellow packets) for all of their kits. It will be beer, just not true Pilsner. My first ever batch was a Brewhouse Pilsner kit with Coopers yeast, was drinkable but can't say it was great. For most beer styles yeast responsible for about 80-90% of flavour profile. I can take exactly same grain bill and use different liquid yeast to make Pale Ale, Munich Helles, Pilsner and Kolsch. All 4 will taste very different due to specific yeast. So its not about a kit you using, its about the yeast for the most part. You will learn that first hand soon
