Hobby Sauces are an Eat-At-Your-Own-Risk proposition. Since they are not licensed, there is no way to know whether they are safe or not other than making educated guesses based on posted recipes, pictures etc. All those who receive hobby sauces as gifts or whatever in the PepperPeople thread have the choice to eat them or not. They may post a "thanks for the box including sauce" but whether or not it's ever actually eaten...we don't know. I know someone who received a free bottle of hobby sauce that PFFFTTT'ed out like a pop bottle when they opened it, so that bottle got pitched.
Most hobby saucers don't have pH meters. A lot can be determined from a complete recipe, but if someone is in the Hobby phase with intentions to go Legit, they will not want to publically post a recipe with ingredient measurements.
Woozies are cheaper to mail than 8oz canning jars, and the HWB/HotFillHold methods are similar, but it's up to what the Hobby-ist has or can find. There are several no-minimum bottle companies. But some sauces are thicker/chunkier and would do better in canning jars instead of woozy bottles.
Without having any input from admins about this,
I'd suggest -either-
someone who has some hobby sauces to trade start a thread offering to trade with other hobby saucers. Actual connections/trades should be done via private PM. No money should change hands including compensating for addition shipping charges for larger bottles. It HAS to be a No-Money transaction.
A person could post their Hobby Sauce with descriptions, pics, etc and those interested could PM with offers to trade. Those interested would "hook-up" in PM and they could accept or decline the offer to trade.
-or-
each individual who has a sauce to trade post it somewhere. I don't know where, as the THP forum in general is pretty good about not supporting illegally produced sauces being sold (which hobby sauces are not) but still...I don't know what The Boss's stance is on this topic.
Most hot sauce producers start out as hobby saucers. It's a huge step in the process if someone wants to take it up a notch, and there are also tons of fantastic sauces being made by people who just like messing about in the kitchen and want to share. Just so long as everyone knows they assume the risk to eat-or-not-eat and no money is involved.
For those hobby saucers who are looking to go Pro, there's ways to get your sauces out for feedback from serious sauce fanatics and foodies. There've been other posts about this and several folks who have sent out samples for feedback.
