John Bull Barvarian and Export Pilsner Lager

[gullarm]

I have these two kit getting ready to get on the go in a few weeks.

Do they brew out okay with the included yeast, or is it worth using S23. yeast.

This is my summer party beer and want to make sure its bob on.

I used Brewferm lager yeat ( 2 packets ) on my last lager brew and it tastes cack and after cracking opening a bottle its nearly flat.

I may move the lager to the shed till later in the year see if it improves.
