In Dragon Age: Inquisition, there is an unmarked quest called "Bottles on the Wall." The quest has nothing to do with the main plot nor does it have a story. Basically, it is just a collection of various bottles of Thedas' malts, meads, brandies, and reserves. Every bottle found comes with a little Codex Entry and 200 influence.
Also, players can admire their bottle collection in Skyhold. Like the quest itself though, the collection is a little hidden. The bottles found around Thedas get placed onto a set of shelves found in the basement of Skyhold's lower courtyard.
Finding all 29 bottles in the vast lands of Thedas can be like searching for a needle in a haystack. This is especially true considering the fact that the bottles are all located in large maps such as the Hinterlands and Western Approach. Some bottles you will stumble on during main quests, while others are pretty out of the way.
Bottles In Crestwood
*Important note: Do not look for any of these bottles until after you drain the lake as most of the bottles are in that area.
- Antivan Sip-Sip: Head to the Glenmorgan Mine area. This bottle is located deep in a cave close by to The Guide of Falon'Din landmark, aka the statue of the owl. To get there, go northwest of the Three Trout Farm Inquisition Camp. The cave is down the hill of an astrarium in the region.
- Hirol's Lava Burst: Travel south of the Flooded Caves. The bottle is in a closed house in the drained lake area near the place where you do a quest for a spirit called "Burdens of Command."
