I picked up a bottle of the Hamilton 151 after following a couple threads on TikiRoom discussing replacements for LH 151. (A limited supply of Hamilton's available now at Spec's downtown Houston, for those in the area. I understand that Hamilton distribution is tiny. There is no more LH in Texas as far as I know.) I don't recall anything about this in what I've read online, so I'm a bit skeptical, but the guy who ordered it for me said the distributor told him that Hamilton bought the old LH production facility and is using the same recipe as LH 151 for Hamilton 151... taking that with a big grain of salt.
Hassouni, I'd agree with your conclusion--Hamilton 151 is a good sub for LH 151. Side-by-side, they taste pretty similar, if perhaps a little weaker and less concentrated in flavor than the LH.
People on TikiRoom are saying there's a yellow label LH 151 floating around... not really sure what this means for the product's future.
Do you mean the yellow label LH 151 that proceeded the more recent red label version of LH 151 that seems to be discontinued as well at the moment? Don't have a picture handy but shown here on this website if you scroll down a bit. Might be a few of them still floating around. Worth buying the old yellow label version to me if I see it and the price is reasonable.
