Ristretto is traditionally a short shot of espresso made with the normal amount of ground coffee but extracted with about half the amount of water. Since ristrettos are essentially the first half of a full-length extraction, the faster-to-extract compounds predominate in a ristretto. The opposite of a ristretto is a lungo, which is typically double the shot volume. Ristretto means “limited” or “restricted” in Italian whereas lungo means “long.”

Drinking more coffee is linked to a lower risk of depression, according to a review of 26 studies published in Australian & New Zealand Journal of Psychiatry in 2016. For each cup of coffee consumed per day, the risk of depression decreased by 8 percent, the researchers found. However, it's worth noting that too much caffeine can cause problems in people who also suffer from anxiety, negating any beneficial effects the coffee can have on depression risk.
