Narrative:
On final runway 35L den; approximately 500 ft AGL; experienced a 20 kt loss of airspeed followed by a windshear warning. We started an escape maneuver and after two windshear callouts; the warning ceased and we continued with a normal go-around. On downwind; we were told to plan on the visual approach to 35R; adding to our workload. I selected managed speed [and] the aircraft started to accelerate. I'm not sure if I activated the approach; but I could have sworn the speed bug was at vapp. To prevent a flap overspeed; I disconnected the auto pilot and auto throttles and went to idle power. We were definitely unstable at 1000 ft; but we were day VMC. I continued high and fast; working back to glideslope and approach speed. We then got a master warning light with 2 ECAM messages. I saw the one labeled 'engine 1 egt over limit'. This confused us; because at that time; the power was still at idle. As we neared 500 ft; still 15 kts fast; coming out of idle; engines starting to spool up; I elected not to go around because I was uncertain of the condition of the #1 engine. Smooth winds; long runway; it was a safe landing. I never caught the 2nd ECAM message.

Narrative: On final Runway 35L DEN; approximately 500 FT AGL; experienced a 20 kt loss of airspeed followed by a Windshear warning. We started an escape maneuver and after two windshear callouts; the warning ceased and we continued with a normal go-around. On downwind; we were told to plan on the visual approach to 35R; adding to our workload. I selected managed speed [and] the aircraft started to accelerate.

We were definitely unstable at 1000 FT; but we were day VMC. I continued high and fast; working back to glideslope and approach speed. We then got a master warning light with 2 ECAM messages. I saw the one labeled 'ENG 1 EGT OVER LIMIT'. This confused us; because at that time; the power was still at idle. As we neared 500 FT; still 15 kts fast; coming out of idle; engines starting to spool up; I elected not to go around because I was uncertain of the condition of the #1 engine.
