That's a bummer losing a batch ... which actually I did once, too. I started last January, too. The first time I tried an all DME batch, I didn't apply enough thought to the water / DME ratio, which I had way too low (not enough water for the boil). I carmelized the extract .... since I had only used HME's before this, I didn't recognize the problem quick enough, and actually stank up the house so bad, I never thought the smell of burned sugar, which is awful, would ever go away. It did.
I never made that mistake again. Now, doing a DME hop boil is treat. I love going from the aroma of steeped grain, to malt, to hops. But I'll never forget that first one, which was a nightmare.
I also like the Northwestern extracts in pouch in box, that BHB sells. Nice.
I'm trying AG in a bag for the first time this weekend let's hope I don't screw it up, but after so many batches of great beer, I figure I know enough to avoid major pitfalls, but who knows?
