I'm making a wort chiller. That's just a spiral of copper tubing to cool
boiling hot beer brew to put into the fermenter. I need to join the ends,
and in the configuration it's in, it would be easier to use a sweat fitting
than a compression. Is there any problem with that small amount of solder
regarding lead?

Yes, there would be a problem with food contact, since it's too easy
to over do it and have big drips and runs of solder on the inside you
can't see - but that's okay, when you go looking for plumbing solder
it's ALL going to be lead-free now by law, mostly Tin with a little
Silver alloyed in.

Even electronics is being forced to get rid of the lead. They're
going to get burned with $1 Billion satellites dying and falling from
the sky due to Tin Whiskers causing shorts on circuit boards, but the
few Rocket Scientists can't out-shout the many Enviro-Nuts.

There is also Silver-Braze if you need to stay away from Tin too -
that's mostly Copper and Silver. You need a little more heat, but
MAPP and Air-Acetylene will get there for smaller sizes.
