A while ago I was emailing back and forth with Bull City about some unrelated issue and I casually asked them if they could tell me the weight of their bottles with tip, cap and label. They responded that a 30ml bottle weighed 5.91g with cap and label but without the tip. I just weighed a few tips I have and they were all ~.28g. They also said a 10ml bottle weighed 3.29g w/ cap, label, no tip.
I use a juice calculator that keeps track of my inventory and I try to be vigilant about adjusting my inventory after every bottle I make but sometimes you forget or sometimes who knows what happens. Point is, with this number you can quickly determine how much concentrate (in grams) is left in a bottle from Bull City Flavors.
TL;DR:
- 30ml bottle from Bull City Flavors w/ tip, cap, label: 6.19g
- 10ml bottle from Bull City Flavors w/ tip, cap, label: 3.57g
Helpful information. You are way more inventory focused than me. I just add it to my order list when the bottle hits 25%
I couple dozen flavors I use the most frequently I have in 120ml or larger bottles out of sight so that doesn't always work. Inventory management is key! Especially when you suddenly want to make 200ml of a juice, it's nice when your calculator can stop you before you even start.
Anyway yeah, this is just a quick and dirty way to gauge your remaining supply.
I've noticed indifferences with the weight of plastic bottles, same ml size but the weight may be slightly varied, but that is just my experience.
In a week or so I'll probably be running out of bavarian cream 10 ml bottle from nic river, I'll weigh it and post here. Thanks for the link to your calculator. I want to check it out. I was going to use ATF but to use the batch feature you have to pay for it. So I use ELR and a spreadsheet I created. I put in the start weight (10 ml) for each flavor I bought and as I mix I put the weight in for each flavor. Then that weight is subtracted automatically from the start weight. When a flavor is getting low I put it on my to buy list.
The calculator I use is not portable or even mobile but provides a ton more functionality. I only ever mix at home though so I don't need my recipes on the go.
