I'm planning to run a series of 2.5 gal test batches to zero in on the flavor I'm looking for. I decided to do this after a couple of batches at full scale 5 gal didn't turn out how I wanted. I know extract would be a big time saver for these testers but I can't seem to find extract in any quanity.12 bucks for 3 lbs just kinda stings a little is ther anywhere that might sell it in bulk? or should I consider doing the testers as all grain to control cost. Thanks
