Coffee Ages telomere length of Cells but beer extends length

I'm going to continue with both.

Coffee Every Day Keeps the Dementia Away 

Moderate consumption of beer is associated with lower cardiovascular (CV) risk- better endothelial function

Don't do anything stupid based on this, its for yeast cells.

Coffee Ages Cells
But a glass of beer might have the opposite effect, according to a study of telomeres in yeast cells.
The length of these end caps on chromosomal DNA, which determine how many times a cell can replicate with implications for both aging and cancer, grew when cells were exposed to alcohol or vinegar but shortened with caffeine or high temperatures.
Oxidative stress and a number of other environmental stresses tested had no impact on telomeres, Martin Kupiec, PhD, of Israel's Tel Aviv University and colleagues reported inPLOS Genetics.
"For the first time we've identified a few environmental factors that alter telomere length, and we've shown how they do it," Kupiec explained in a statement. "What we learned may one day contribute to the prevention and treatment of human diseases."
