These days I steer clear of supermarket packs - in past years I found these made very ordinary beers.
Anyone tried using two cans of supermarket beer mix in a batch (with no extras)? It would be stronger but might also have some flavour, and would be cheaper than augmenting a kit with a brewpack. Two packs in 30 litres might be OK....
Currently brewing: cider - Black Rock + 1kg dextrose + 250 gm lactose + 6 Fuji apples. OG 1.040.
