We report the discovery of 9 new hot molecular cores in the Deep South (DS)region of Sagittarius B2 using Atacama Large Millimeter/submillimeter ArrayBand 6 observations. We measure the rotational temperature of CH$_3$OH andderive the physical conditions present within these cores and the hot core SgrB2(S). The cores show heterogeneous temperature structure, with peaktemperatures between 252 and 662 K. We find that the cores span a range ofmasses (203-4842 M$_\odot$) and radii (3587-9436 AU). CH$_3$OH abundancesconsistently increase with temperature across the sample. Our measurements showthe DS hot cores are structurally similar to Galactic Disk hot cores, withradii and temperature gradients that are comparable to sources in the Disk.They also show shallower density gradients than Disk hot cores, which may arisefrom the Central Molecular Zone's higher density threshold for star formation.The hot cores have properties which are consistent with those of Sgr B2(N),with 3 associated with Class II CH$_3$OH masers and one associated with anUCHII region. Our sample nearly doubles the high-mass star forming gas massnear Sgr B2(S) and suggest the region may be a younger, comparably massivecounterpart to Sgr B2(N) and (M). The relationship between peak CH$_3$OHabundance and rotational temperature traced by our sample and a selection ofcomparable hot cores is qualitatively consistent with predictions from chemicalmodeling. However, we observe constant peak abundances at higher temperatures($T \gtrsim 250$ K), which may indicate mechanisms for methanol survival thatare not yet accounted for in models.
