Clue: When it's not run out, love getting into popular tipple, excellent Scotch (6)
Answer: BEEZER
Explanation: Definition: excellent Scotch
**ZE**(ro) ("love", without r.o. ("run out", in cricket)) *getting into* **BEER** ("popular tipple") 
*I've always used the word "beezer" in phrases like " a beezer catch" without realising that it was a Scottish word – I had assumed it was standard English.
