so... how many units was your largest production run of spices to date?
Should be simple enough to do some math, figure out what your production can be. If you have to limit order size... (Gasp! NOOOOOOoooo!) just tell the customer you can supply 60% of their order by XXX date and the rest by YYY date. Talk to them and let them know that as order size increases, you will be scaling up production for a faster turn around, while keeping the runs to just the size needed to insure a FRESH, Quality, made to order product.
If we are talking about the spice blends, what ingredients are you growing your own and what are you sourcing thru spice suppliers or other growers? What can you get from other quality spice and herb suppliers?
For my salsa, the spice blend contains about 12 ingredients. I used to measure out about 6 batches worth at a time into #5 spice jugs. It got to the point where I was having to monitor inventory of 12+ ingredients, take the time to mix up the bulk batches, and then I was getting so fed up with having ONE MORE THING to keep track of...
Eventually, I contracted with Firehouse Flavors (originally Firehouse Pantry) to custom make the batches and seal in foil pack bags. One Bag, One Batch.
I also did the same with the Texas Creek Chipotle Dip Mix. Mix one small foil packet with 2cups sour cream/mayo for a creamy spicy dip mix. This one was packaged by a company in Seattle.
The idea and recipes are all mine, I just have others do spice packaging. I think for the salsa blend, the full batch recipe makes ~50 salsa batches. For the smaller spice dip mix, I think the full batch yielded ~350 (?) packets. It was pretty cost effective given the stress and aggravation of having to monitor all the ingredients and the (aw Crap! I forgot to pick up something, and it is 10 miles to the nearest grocery store for me...)
Let me know if you want more info.
