Hi all, I need to buy a keg suitable for secondary fermentation/carbonation and then serving. Ive been looking at a keg with simple vent cap and tap at the bottom rather than s30 valves and having to use co2 cartridges. would a vent cap be suitable enough to carbonate my beer?

I've seen corny kegs with caps that have been outfitted with airlocks (its just an extra cap with a hole drilled, grommet added, and airlock inserted).

However, you cannot carbonate a beer in a vessel with an airlock. Carbonation builds pressure and it will all escape if the vessel isn't sealed.

Look up spunding valve.

You can ferment in a keg with airlock lid once down to about 3-4 points from FG throw on a normal lid with spunding valve on the "gas out" post
Idea behind this valve is keeping the internal pressure between 12-18psi at end of fermentation to natraully carb with your batches own co2 blowoff.
You can save a BUNCH of money on co2 this way if you forcecarb
