There are times where you really need to know how pungent something is, and I agree that pepper sauce probably isn't the top priority. A lot of folks in my lab used to measure capsaicin concentration in a QC lab setting. The product? It was a topical capsaicin cream, and so it was considered an...

I don't think folks do understand the reliability of HPLC. Reliability is something that itself can actually be measured and quantified. In fact, for method validation and method transfer between labs, that's actually pretty important. I've seen no evidence that "long time members" have done the...

Well yes, it can be, and that word choice wasn't at all by accident. I would also add that that for maximum precision, chromatography is also your only hope. The alternative is... what? A magic eight ball? A ouija board? Divining the answer from chicken innards? I'm not saying that you sent...

HPLC can be EXTREMELY precise. The question is: what protocol did these labs run? If they follow identical protocols, they should get statistically equivalent results. If you find a lab that follows good laboratory practises (i.e. "GLP compliant"), and you have a validated method, you will get...

Greetings from Minneapolis! :)

Thanks, willard3! That's the tricky thing about what is really definable as a "variety"; every variety itself represents a statistical function of genetic variability. Where do you set limits, particularly when you're dealing with large, multivariate, overlapping distributions? I'm not a...

I second that. There are a lot of great people here who will help you get started with seeds (you've come to the right place!), though if you're looking for rare, hot and reliable, pepperlover.com delivers great stuff. Judy take quality control very seriously, so you know you're getting good seeds.

I have listened to Willard -- he's a great source for a lot of info. Unfortunately, the question remains: is there a list of varieties of peppers from Mexico, within information on which states they came from? It turns out, this doesn't look like can be answered easily. It would be nice to have...

Update: I found a couple resources that are looking a little more promising, but still not quite there. I'm beginning to have the sinking feeling that something like this doesn't exist. One thing which I think folks here will enjoy is a search engine by EURISCO, which is an international effort...

Any experience with these? Allegedly, they range from mild to hot, depending. Is it just a lot of genetic diversity within the population, or is it just unusually susceptible to growing conditions? How do they otherwise taste? (the number of Indigenous American varieties in my garden is lower...

Golden cayennes have a lovely, delicate flavor to them. They're prolific too.

Does this include all (semi) boxy-shaped C. chinense varieties, or does it have to have 'habanero' in the title? 'Madame Jeanette' is really something special flavor-wise.

You are not alone with this problem! There are multiple discussions on this topic, including here, here, here, here, and here. There are many different solutions; the one I'm trying right now is the gelatine capsule idea from Yaotsin (with pictures in the last link.)

Most of my favorites are all chinense --especially Mako akokosrade and Madame Jeanette. There are a lot of amazing Trinidad varieties.

Plant breeders' rights are a type of intellectual property, and in the US, it works a lot like a patent. If you come up with a new and unique stable variety (or hybrid), you can register it with the USDA, and retain exclusive rights for 20 years. The idea is to encourage people to develop...

Aparently, your correspondentwork is from Vienna. He says that the variety is still protected by AISPES, and who knows how long that will continue. He says that for 20 EUR that you can register and participate in trades there, and in his opinion, he thinks they are worth supporting. (That was...

I'm still looking to see what's out there. Seedbanks like CGN and GRIN are surprisingly limited in detail. i did come across this article, which is interesting; http://dx.doi.org/10.3732/ajb.0800155/ There's a cool map showing the genetic diversity 9as measured by haplotype) of C. annuum within...

Hi there, Does any body know of a resource for finding pepper varieties from Mexico by state? There are a lot of varieties out there associated with Yucatan and Oaxaca , but when I look for Chiapas, I get nothing. There must be this information out there. Any advice?

Overnitrified soil is a different thing altogether. If all you want is to raise the pH, then some slaked lime would do it. If you're trying to go for large-scale denitrification of something a little larger (e.g. poorly managed farmland), then you need something a little more sophisticated (see...

Hi there, In fighting to keep pH values in a nice stable range, has anybody here used polymers with acid functionalities to maintain a stable pH? I started looking around, and I see some commercialized cross-linked polystyrene sulfonate out there, but polyacrylate and polymethacrylate-based...
