I've got some Coopers Stout finished, but still young, I used some of the LME to replace sugar.
The LME seems to be a good product, it was easy to use I'd recomend it as a sugar replacement. Especially so as the price is better than most.
Over the weekend I'll be doing a small full extract batch/partial mash (bitter) using LME and I will post a review of it when it's brewed and tasted.
