I have tried to search for this but can't locate a thread.

What is the formula to use if you are converting some previously mixed 1:1 syrup to 2:1? For example, assume you have 10 cups of 1:1 already made, something tells me it's not as easy as adding 5 cups of sugar to that pre-existing mixture.

Any help is appreciated.

Thanks,

Kevin

Being a small scale (like yourself), I operate by standard 4lb grocery store sugar bags.

This makes 2:1 mix trivial.

Mix one 4lb bag with one quart of water - done (you got yourself 2:1 mix).

This also makes 1:1 mix trivial.

Mix one 4lb bag with two quart of water - done (you got yourself 1:1 mix).

For larger amounts - multiply quantities proportionally.

Back to your question - I would just keep adding sugar incrementally and stir until dissolved.

Then maybe add more.

In fact, just feeding 1:1 as it is - a total non-issue (remember, today is July 31st and still a deep summer yet).

You can feed them 1.5:1, 1.7:1, 1.35:1, 1.98:1, .......... - it does not matter what you feed.

Unsure why the hang-up.
